CELL VARIANT

Hi Experts,
Could you provide me detailed information on how to use the cell variants in a normal table in Webdynpro ABAP (using the cell variants to make a read-only field as input field/dropdown field on the click of a button).
Thanks in Advance,
Mirza.

Hi Mirza,
Please go through this excellent [blog|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f0e7461d-5e6c-2b10-dda9-9e99df4d136d] by Suman Kumar in which he explains usage of cell variants to make the cells of a column as checkboxes or textviews dynamically.

Enhancing a standard component - Table Cell Variant

Hi Forum,
I am trying to enhance the standard WD component /SAPSRM/WDC_UI_SC_DOTC_BD view V_SC_DOTC_BASIC in SRM 7.0 .
The requierment that for certain condition the Quantity cell in a row should be read only.
Carried out the following steps:
1. Created an enhancement
2. In the standard table column ITEMS_TABLE_QUANTITY [Columns] , removed the standard inputfield.
3. Added two cell variants ZITEMS_TABLE_QUANTITY_CV1 [CellVariants] and ZITEMS_TABLE_QUANTITY_CV2 [CellVariants] first one contans a text view and second contains inputfield. Variant key for first one is DISPLAY and for second one is EDITABLE.
4. Enhanced the method WDDOMODIFYVIEW with below code:
**Read the ITEMS table
DATA lo_nd_items TYPE REF TO if_wd_context_node.
DATA lt_items TYPE wd_this->elements_items.
DATA ls_item LIKE LINE OF lt_items.
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA ls_context TYPE wd_this->element_context.
DATA lv_disable_quantity TYPE wd_this->element_context-enable_quantity.
DATA lr_table_column TYPE REF TO cl_wd_table_column.
** navigate from <CONTEXT> to <ITEMS> via lead selection
lo_nd_items = wd_context->path_get_node( path = `COMP_CONTEXT.ITEMS` ).
lo_nd_items->get_static_attributes_table( IMPORTING table = lt_items ).
lr_table_column ?= view->get_element( 'ITEMS_TABLE_QUANTITY' ).
LOOP AT lt_items INTO ls_item .
 IF ls_item-catalogid EQ 'VEP_Staples_D0'.
 lr_table_column->set_selected_cell_variant( value = 'DISPLAY' ).
 ELSE.
 lr_table_column->set_selected_cell_variant( value = 'EDITABLE' ).
 ENDIF.
ENDLOOP.
But even after the condition is true ALL cell i.e. the complete column is DISABLED or when the condition is false the COMPLETE column is enabled instead of enabling disabling ONLY THE SPECIFIC CELL.
Is there a problem with the code in WDDOMODIFYVIEW or something else?
Thanks,
Anubhav

Hi Saravanan
Under ITEMS node I added one more Node(cv_quantity) and one attribute(cell_variant_quantity) with in this node.
And code in WDDOMODIFYVIEW :
DATA lo_nd_items TYPE REF TO if_wd_context_node.
DATA lt_items TYPE wd_this->elements_items.
DATA ls_item LIKE LINE OF lt_items.
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA ls_context TYPE wd_this->element_context.
DATA lr_table_column TYPE REF TO cl_wd_table_column.
** navigate from <CONTEXT> to <ITEMS> via lead selection
lo_nd_items = wd_context->path_get_node( path = `COMP_CONTEXT.ITEMS` ).
lo_nd_items->get_static_attributes_table( IMPORTING table = lt_items ).
lr_table_column ?= view->get_element( 'ITEMS_TABLE_QUANTITY' ).
DATA lo_nd_cv_quantity TYPE REF TO if_wd_context_node.
DATA lo_el_cv_quantity TYPE REF TO if_wd_context_element.
DATA ls_cv_quantity TYPE wd_this->element_cv_quantity.
IF first_time EQ abap_true.
lr_table_column->set_selected_cell_variant( value = 'EDITABLE' ).<--Initially ALL cells shoud be editable
ELSE.
lr_table_column->bind_selected_cell_variant( path = 'COMP_CONTEXT.ITEMS.CV_QUANTITY.CELL_VARIANT_QUANTITY' ) .
* navigate from <CONTEXT> to <CV_QUANTITY> via lead selection
lo_nd_cv_quantity = wd_context->path_get_node( path = `COMP_CONTEXT.ITEMS.CV_QUANTITY` ).
IF lo_nd_cv_quantity is BOUND.
lo_el_cv_quantity = lo_nd_cv_quantity->get_element( ).
 LOOP AT lt_items INTO ls_item .
 IF ls_item-catalogid EQ 'VEP_Staples_D0' AND ls_item-number_int IS NOT INITIAL AND ls_item-description IS NOT INITIAL.
 lo_el_cv_quantity->set_attribute(
 name = `CELL_VARIANT_QUANTITY`
 value = 'DISPLAY' ).
 ELSEIF ls_item-catalogid NE 'VEP_Staples_D0' OR ( ls_item-number_int IS INITIAL AND ls_item-description IS INITIAL ) ."If the condition is not satisfied OR no item is added to that line
 lo_el_cv_quantity->set_attribute(
 name = `CELL_VARIANT_QUANTITY`
 value = 'EDITABLE' ).
 ENDIF.
 ENDLOOP.
ENDIF.
ENDIF.
Now If I add an item that DO NOT satisfy the comdition to be read only, for that row the quantity is enabled but for all the rows below it quantity cells are DISABLED.
Hope my issue is clear?
Thanks a lot,
Anubhav

Example we are trying is
You need the option to select a single cell to provide a value help for individual cells, for example.
The interface TableSingleMarkableCell allows you to group cell variants in any way as you like and to make a single cell selectable in this group. The following example shows how to proceed if you want to implement a selection of a single cell from an entire table.
Prerequisites
You have created an applicaton with a component and view in your Web Dynpro project.
Procedure
Creating the Context
 1. Create a value node TableNode for the data of the table and insert three value attributes of the type String for the table columns.
 2. Create a value attribute selectedCellVariant of the type String in the TableNode.
 3. Create a value attribute attributePointer, switch to the Properties, click for the property type, and select the Java Simple Type. Enter com.sap.tc.webdynpro.progmodel.api.IWDAttributePointer and confirm with Ok.
Creating the View
 1. Open the context menu in the Outline, select Apply Template and then Table. In the subsequent dialog box from the context, select three attributes for the columns (col1, col2, col3). Confirm by choosing Finish
 2. Set the property selectionMode of the table to none.
Repeat the steps for each column.
 3. Highlight the column and open the context menu. Select Insert Cell Variant, TableSingleMarkableCell and confirm with Finish.
 4. Enter the same value for each TableSingleMarkableCell for the property variantKey - for example, variant1
 5. Insert a cell editor of the type TextView in each TableSingleMarkableCell.
Binding the UI Elements
 1. Bind the text property of each TextView to the column in which the property is contained.
 2. Bind the attributeToMarkproperty of the corresponding TableSingleMarkableCell to the column in which the element is contained.
 3. Bind the selectedCellVariantproperty of each TableColumn to the context attribute selectedCellVariant.
 4. Add the following source code to the wdDoInit method.
wdDoInit()
1
2
3
IPrivateUseSingleMarkableCellsView.ItableNodeElement elem;
 int count = 10;
// Fill dummy data
 for(int i=0; i<count; i++) {
 elem = wdContext.nodeTableNode().createTableNodeElement();
 wdContext.nodeTableNode().addElement(elem);
 elem.setCol1(1. + i);
 elem.setCol2(2. + i);
 elem.setCol3(3. + i);
// set TableSingleMarkableCell as a variant for the table
 elem.setSelectedCellVariant(variant1);
 For each element that is created in the for loop and is then added, the
 TableSingle MarkableCell is set as a cell variant in row 3.
 5. Add the following source code to the wdDoModifyView method.
wdDoModifyView()
IWDAttributeInfo markedDataInfo = wdContext.currentContextElement().getAttributePointer(attributePointer).getAttributeInfo();
 ((IWDTableSingleMarkableCell) view.getElement(TableSingleMarkableCell1)).bindMarkedData(markedDataInfo);
 ((IWDTableSingleMarkableCell) view.getElement(TableSingleMarkableCell2)).bindMarkedData(markedDataInfo);
 1. ((IWDTableSingleMarkableCell) view.getElement(TableSingleMarkableCell3)).bindMarkedData(markedDataInfo);
The current AttributeInfo is now retrieved at every change of the view and is bound to the context using the markedDataproperty.
Result
Each single cell can be selected separately. You can define an action and in its method, you can determine the coordinates of the currently selected cell using the following code:
IWDAttributePointer attPointer = wdContext.currentContextElement().getAttributePointer();

Hi Gangadhar,
at first: you are right: you have to choose
com.sap.ide.webdynpro.uielementdefinitions.AttributePointer
and not the other one. I already updated the documentation for this.
In which SP are you working?

How to add cell editor to cell variant dynamically?

Hi everyone,
I'm developing a web dynrpo component. In one of the views , I need to modify the view dynamically
because the data structure only can be determined at runtime. And the table column should have two
cell variants. I don't know the exact cell variant class which should be used. I only find an abstract class about cell variant CL_WD_ABSTR_TABLE_CELL_VAR , but I can't find any method in this class which
can add cell editor under this cell variant.
Thanks in advance.

Hi Sireesha,
Thanks for link you provided.
I am able to add Column with CommandImageLink.And onclick of that link i am able to display another popup.
Now another problem which i am facing is when i select one row from popup and click "Ok" i have to modify some columns from Dyanamic table which is displayed on main page.
For this.
1)First i took the selected row from dyanamic table to update that perticular row depending upon the row which i select from popup.
if you see the code above i am refaring the list as collection for data.So i am updating that collection but again it is refreshing to it's original value.
because number of times getList() method of bean get's called equal to number of columns. which brings the values from database.
Here On click of popup's Ok button I don't want to save the data for table i just want to show there in some column's .and After click on SAVE button from table i have to save it.
Let me help how can i modify the Dynamic table's data.
Thanks for all help.

Use of Cell Variant for a normal table

Hi Experts,
I have a requirement in a normal table where a row is first in read-only mode, then on click of edit button (given on that row),
the row should become editable and also edit button should become invisible and two more buttons update/cancel have to be visible. How to achieve this using a cell variant for this normal table.
A detailed reply would be appreciated.
Thanks in Advance,
Mirza Hyder.

Hi Mirza,
Cell variant property is used to chenge the cell property not for other.That means in one cell you want checkbox and in other cell you want textview like this you can change the property of cell as you want.
Test this standard program WDR_TEST_TABLE in that test view cell varint for your understanding.
Coming to your requirement.You can do in this way.
Check in the below thread in that i gave code to make the entire row is editable when you click on the lead selection of row.I gave code for ALV.I hope that code is use ful for you.
How to make all columns of alv editable
To make tool bar buttons disable and enable:Write your logic in method handler of lead selection event like change the visible property of button to none.
Note: In the event handler method you dont get reference of view.You only get reference of view in WDDOMODIFYVIEW only so take a global variable of type ref to if_wd_view and populate that global variable in method WDODIFYVIEW.So that you can access any view element in any method.
For cell variant in ALV check this Article written by me.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f0e7461d-5e6c-2b10-dda9-9e99df4d136d

Setting new cell variant for an alv table column

Hi,
I want to set a new cell variant for a column. Therefore I did the following steps:
1. Create an object of CL_SALV_WD_CV_STANDARD
2. SET_KEY( 'CELLVAR1 )
3. set_cell_design([..]-goodvalue_medium )
4. SET_EDITOR( lr_alv_input_field )
After that I added the cell variant to the column by using the method "add_cell_variant".
The last step is to call method SET_SELECTED_CELL_VARIANT.
I checked my program by using get_selected_cell_variant( ) and the return string was okay.
But when the table is displayed, the new cell variant isn't working. I defined an input field as the cell editor for my new cell variant but when the table is shown, it is just text - no input possible. In addition to that the selected cell design (goodvalue_medium , step 3) isn't working. So I think the cell variant is not used.
Can you help me?
Thanks & Regards,
Hendrik

Hi
I wonder if you can help me please, I too am having issues implementing ALV cell changes in WDA?
I am basically trying to dynamically change the individual color of a cell (not the entire column or row) dependant on certain criteria. I apologies but find that you are the closest resource for any potential information. Please see screen shot below.
Currently my code is as follows:
see: www.picasaweb.google.co.uk/dave.alexander69/Pictures#5244416971466907938
data: lr_cv TYPE REF TO cl_salv_wd_cv_standard.
loop at table 1 row data
 loop at table columns
 for the date columns only...
 IF <fs_column>-id(4) = 'CELL'.
 get and set column header dates from select option user input - done
 loop at table 2 row data (table 2 contains date ranges for row concerned)
 MOVE: ls_zdata-variance TO lv_variance.
 method 1 - as in sap press WD4A -:
 lr_cv = cl_wd_table_standard_cell=>new_table_standard_cell(
 view = view
 variant_key = lv_variance ).
 as mentioned...
 CREATE OBJECT lr_cv.
 lr_cv->set_key( 'VARIANCE' ).
 lr_cv->set_cell_design( '09' ).
 lr_cv->set_editor( lr_input_field ).
 lr_column->add_cell_variant( lr_cv ).
 lr_column->set_cell_editor( lr_input_field ).
 lr_column->set_sel_cell_variant_fieldname( 'VARIANCE' ).
 lr_column->set_cell_design_fieldname( value = 'COLOR_CELL' ).
 lr_field = lr_table->if_salv_wd_field_settings~get_field( <fs_column>-id ).
 lr_field->if_salv_wd_sort~set_sort_allowed( abap_false ).
 the only way I get cell coloring to work - but this is for entire column?
 ls_zdata-color_cell = cl_wd_table_standard_cell=>e_cell_design-one.
 MODIFY lt_zdata FROM ls_zdata..
 ENDLOOP.
 ENDIF.
 IF <fs_column>-id = 'COLOR_CELL'.
 CALL METHOD lr_column->set_visible( EXPORTING value = '00' ).
 ENDIF.
 ENDLOOP
 ENDLOOP.
As you see I am in the dark a bit regarding cell variants and wonder if you can point me in a better direction.
Many thanks for any help,
Dave Alexander

Dynamic Cell variant assignment

Hi
I wish to dynamically assign a table variant with a cell editor of type checkbox and then check/uncheck/make readonly the field accordign various situations. I only wish this to happen on certain rows.
So far I can achieve this my using context attributes and binding to these. My only concern is that there are a lot of extra attributes required as thses cell variants appear on 7 columns and then 8 tabs.
I would prefer to achive this solution by using the view->get_element approach, but so far I have only managed to assign the cell variant to the entire column and not an individual cell.
Any ideas?
Cheers
Ian
Edited by: Ian Stubbings on Mar 10, 2008 8:52 AM

Hi,
In case of a checkbox, based on the value of the attribute bound to the checkbox column, the checkbox will be checked/unchecked. Anyways, you have to have a context node of cardinality 0...n, with an attribute which can be bound to the checkbox. As far as readonly property is concerned, you can have an additional attribute in the same context node, and bind that to the read-only property of the checkbox. Alternatively, I think you can use the SET_ATTRIBUTE_PROPERTY of the IF_WD_CONTEXT_ELEMENT class.
Hope this helps.

Usage of Single Markable cell - Cell Variants.

Hi,
Using Cell Variant SingleMarkable Cell, is it possible to set different colours for cell's in a single column ..
If its possible , could someone elobarate on how it works ? And provide info on attributeToMark and attribute pointer..?
Thanks and Regards
Bharathwaj

Hi Bharathwaj,
if you want to set different colors, just use the cell variant TableStandardCell.
You can find documentation here:
http://help.sap.com/saphelp_nw2004s/helpdata/en/ed/785a42793d1653e10000000a155106/frameset.htm
In this case it's described for a TableSingleMarkableCell, but it works in the same way for a TableStandardCell.
Hope this helps
Kind Regards

Web dynpro cell variant!!!!

Hi everyone,
I have a big problem in web dynpro UI development,How can I make it possible

How to disable a single cell in a table (and not the whole column)

Hi there,
I've got a webdynpro table with a few columns, rows can be created dynamically through a button in the table toolbar.
Depending on the value of a certain cell I have to disable another cell (in the same row).
I tried to manipulate the view in the modifyview but no joy. I also tried to manipulate the attribute property through the coding below:
DATA lv_knttp TYPE knttp.
lo_nd_kostl = wd_context->path_get_node( path = `MULTIVALUES.KOSTL` ).
lo_el_kostl = lo_nd_kostl->get_element( ).
lo_el_kostl->set_attribute_property(
attribute_name = 'LTEXT'
property = lo_el_kostl->e_property-enabled
value = ''
but it disables the whole column!!!! I just need the cell to be disabled (I thought the code above, through the lead selection, would affect a certain cell only - but I was wrong).
Any ideas?
Thanks!!!

Hi,
using cell variants you can do this.,
check this article: [Cell Variants in WDA|http://wiki.sdn.sap.com/wiki/display/WDABAP/WebDynproforABAPCellVariants]
Instead of binding the read only property of table as a whole , just bind the read only property of column group of table., You can do this bu drill down the table and select the required column and bind the read only column.,
then In onAction Event of button .,
loop the table, if condition satisfied set the read only property to true else false.,!!
hope this helps u.,
Thanks & regards,
Kiran

How to get selected/focused cell from table, and action on clicked

Hello Web Dynpro Community!
i have a view with a table, (id "Table_0");
table is 3x3 size, as celleditors i used inputfields; (standard binding to context with string atributes)
below table i have textarea.
when i select any cell in table i want to add that cell coords to textarea (col and row)
i know that i should use onLeadSelect action, but i dont know exacly how. or to be precise.. how to access to ID and row variables in that action.
the other problem is.. that onLeadSelect seems to work only when i change lead not the cell in same row.. so prabobly there is better way to do that..
any ideas?
Looking to hear from You.
EDIT:
Now i have following problem:
i have a table 3x3 with one column as dropdownbykey box and 2 as TableSingleMarkableCell (and inputFields As editors).
it works as i wanted:
so when i click on one of those input cells, insert vale AND click enter then the action onEnter( for inputfield) is fired... i can get the coords of that cell..
problem is.. that i want to get the coords before i click enter.. just when i click in cell.
i tried to use onAction event for column.. but it doesnt work for TableSingleMArkableCells (but it works for ddk column correctly).
so there is any way to do that?
ie:
below table i have inputfield (called value).
when i click on cell (and DO NOT press enter) i want to see the cell value in inputfield value.
future (and target need) is that i need to show some additional text for specific Cell. (i have an Object with 2 strings attributes, one i want to show in cell, and one in inputfield when cell is clicked).

F4 help for only a single cell in a table

Dear All,
The requirement here is to provide input help for only a particular cell in a table.
This cannot be achieved by assigning search help to the attribute of the context as this will render all the cells of that particular column with F4 help. I tried applying the cell variant concept but only go up to a certain extent.
I tried OVS as well. But for this to work we need to lead select the entry and then go ahead with F4, which will make is inconvenient for the user.
I even searched the forum for some answers, but i could only go to a certain extent with the help of those.
So, if anyone out there has any idea, please help me out. Also, if this is a repeat post by any chance (i think not) kindly provide me with the link of the original.
Thanks and Best Regards,

       LR_CELL->SET_EDITOR( LR_TEXT ).
    ENDIF.
     LR_COLUMN->ADD_CELL_VARIANT( LR_CELL ).

This code is for setting Text View as cell editor, instead text view u can take input field and use bind_value method to bind with another context attribute.

Dynamically change the cell editor in the table control

Hi..
I have 3 columns in a table . of which in one column we need to change the cell editor dynamically at runtime.
i.e for example i have columns as carrid, connid and fldate.
For the first 2 rows the cell editor for the carrid clomn shud be a dropdown and from there on in the next rows for the same carrid column it shud be a input field.
Can experts plz help me how to achieve this as this is very high priority issue....

Madhu...

This is actaully fairly simple to do. You will need to add a cellVariant to your table column. You can then dataBind a context attribute to the selectedCellVariant property of the column to control which cellVariant will be used. This allows you to control row-by-row which cell editor you want to output.

Also here is an example that I did the other day that uses Cell Variants within ALV. This process is actually a little more complicated because you have to go through the ALV APIs. To do this in a normal table is actually easier because you can create the cellVariant in the layout designer.

Dynamic Table UI Element with different data type for each cell

Hi Experts,
I have a problem with a dynamic Table UI Element in Web Dynpro ABAP. I have the following coding:

Now my problem is, that I need for every ROW of my table UI Element a different cell editor. I know how to change it for the column. But is not my issue. I want to have images (traffic lights red and green) in some rows. The other rows should have numbers. The coding works, so that I have all the data at the right place in my table, only the images are shown as a string, because the cells of these rows have the cell editor Text_View. I tried something with cell variants (with cl_wd_table_standard_cell), but it was not possible for me to get a cell variant "image" in these cells/rows were I need it.
I hope you understand my problem and now what to do here.
Thanks a lot in advance.

Ingmar
