Dynamic rows in TableView Iterator

Hello All,
I am developing an application in which there would be a TableView with last column as a button. OnClick event on the button should add the row below the current row (the facility should be like an Excel spreadsheet where we can insert the rows below). Can it be acheived by re-populating the internal table which his attached with TableView Control.
Is it Ok to use TableView in such a condition or we have to go with pure HTML tables or some kind of ActiveX controls?
Thanks in advance.
Thanks And Regards

Hallo Rajeev,
> Is it Ok to use TableView in such a condition...
It is OK to use the tableView as long as it works for you! Once we run into problems, then of course one has to see if the functionality is "working as designed" and whether it was designed to handle your specific request.
However, what you want to achieve sounds relatively harmless. Just use onclick on the button to trigger a server round trip. (Nice idea: write the row index directly into the onclick string!). Then add a new empty row into your at the correct index (see ABAP documentation), and just render table new.
All of this should be relatively easy. Why don't you try, and let us see what you achieve.

Radiobuttons in tableView/iterator environment

Hi,
I'd like to build and display a matrix of radiobuttons with a name/title for each row and also for each column. Every row of the matrix should form a radiobutton group, i.e. per line one and only one radiobutton should be selectable.
Both dimensions of the matrix are dynamic so I thought I could use a <htmlb:tableView> with a column-definitions table defining the number and names of the columns, the 'actual' table containing the names of the rows and an iterator which just renders these names in the first (i.e. 'zeroth'-) column and radiobuttons in all other columns.
The code in if_htmlb_tableview_iterator~render_cell_start pretty much contains only the lines
rowindex_as_id = p_row_index.
colindex_as_key = p_column_index.
p_replacement_bee = cl_htmlb_radiobutton=>factory( id = rowindex_as_id key = colindex_as_key ).
Unfortunately the radiobuttons don't get rendered, the resulting page contains the desired table with the row and column titles but empty cells. The html sources contains the comments

Now, this might be due to a missing radiobutton group that would contain the radionbuttons of one line.
I don't understand however how a cl_htmlb_radiobutton object gets to know its radiobutton group container. Neither the factory used above nor the constructor nor any other method allows to set a reference to a radiobutton group object. It does contain an attribute radiobuttongroup though, but this is protected!?!
Does anybody have an idea/experience with this?
Regards,
Sebastian

Hallo Sebastian,
First let me address your questions concerning the "parent" of a tag. In principle it is only possible to process a tag in context of a BSP page. In this context "process" means either writing the tag on a BSP page, or dynamically processing the tag. When the tag is processed, it is placed on a stack. The opening sequence puts the tag on the stack, the close sequence removes the tag from the stack. Each tag can query the stack of previous tags to find a specific type or parent. Typical code would be:
DATA: rbg TYPE REF TO CL_HTMLB_RADIOBUTTONGROUP.
rbg ?= m_page_context->GET_CLASS_NAMED_PARENT(
 class_name = 'CL_HTMLB_RADIOBUTTONGROUP' ).
OR
DATA: rbg TYPE REF TO CL_HTMLB_RADIOBUTTONGROUP.
rbg ?= m_page_context->GET_ELEMENT_NAMED_PARENT(
 extension = 'HTMLB'
 name = 'RADIOBUTTONGROUP' ).
OR
DATA: rbg TYPE REF TO CL_HTMLB_RADIOBUTTONGROUP.
rbg ?= m_page_context->GET_DIRECT_PARENT( ).
Next aspect is the error message "Unidentified control NOT rendered". What this means is that deep down in the code we get a reference onto a control which we can not render anymore. It is suddenly not known. Hmmm... let us dig.
What I then checked is with the use of the <htmlb:radioButton>. This control insist that it can only be used inside a <htmlb:radioButtonGroup>. Which actually makes sense. So if no group, then raise error.
Which brings us to your message above. While deep in the rendering, these types of unknown problems are caught and dropped. This is when you get this generic message. It is actually the exception about the missing radioButtonGroup on the stack.
What we usually do, is place the <htmlb:radioButtonGroup> around the <htmlb:tableView>. But this only works when you are using one column of radioButtons. Which you are not.
Current feeling would be to look at some executive programming: consider to use a <phtmlb:matrix> and just roll your own. For an idea of where the journey can go, look at the examples of <phtmlb:formLayout>.

TableView Iterator in WebDynpro as in BSP

Hi all,
i'm planning to move from BSP to WebDynpro ABAP and have a question:
Does WD ABAP provide the same kind of <htmlb:tableView> as BSP? Especially, does it support the concept of an tableview iterator?
Thx & Regards,
Daniel

Yes you'll find everything.
You'll find also the ALV extension of a table.
I was familiar with iterator and I like it so much; in WDA you can reach the same result but in a different way.
Basically you have to prepare, in advance, all the data in the table rows and then in the table configuration you'll describe the rules for each column (even with variants per row).
You have to study the Table UI object with table cell variant and then ALV features.

Hi Mark,
Thanks for your reply. I tried that in DO_INIT and in DO_REQUEST as well. I started of this application well with the values selecting from Dropdown and then rendering the table columns. But now I have commented everything and just trying to render one column of the table....
I have one concern.
I have declared like this
tv_iterator type ref to ZITERATOR.
and in DO_INIT I have instantiated. Create Object tv_iterator.
If you have any suggestions please let me know....
Thanks

 on cli ck = 'modify').
 bee_table->add( element = link level = 1 ).
 p_replacement_bee ?= bee_table.
 endif.
OnInputprocessing of BSP page:
when 'modify'.
 gv_flg_tv_popup = 'X' .

Dynamic Rows in Report Painter

Hello everyone,
I'm new to report painter and m using the SAP Library help material to understand report painter. I've one query though i.e
Is it possible to create a report hrough report painter with dynamic rows ? if yes then pls let me know how.
Regards
Anik

Thank you.
See I have the below Rows
Total Revenue
Cost2
Cost3
Direct Cost
Gross = Total revenue - Direct Cost
Gross % = (Gross/Total revenue ) * 100
I have Columns as with basic Key figures and Formulas
Year(basic key Figure)
Year+1(basic key Figure)
Total = Year + (Year+1)
Its giving me correct values in case of Basic Key figures and not in the formula case.
It giving error when there is formula both in Row and Column.
In the above case last row and last colum. Only Column formula is getting implemented.
Here for example I have mentioned 4 rows and 4 columns.. But I have 15 Rows and 30 columns .. out of which 15 rows and columns have formulas...
% Rows are problem.. which gives me errors... I tried using Special cells, but I am not 100% sure how to use them.
I would be very thankful if you can help me out.. Please

How do I set the value of a dynamic row text field

I have a repeated row form which contains a button and multiple text fields. There is a text field (Input Data Field) further up with some information I want to place in the table and multiple buttons that I want to read the value of and set to the table. I apologize there are multiple questions I have and I am using pseudocode to describe it.
Top form looks like
InputField
| ButtonX1 | ButtonY1 | DescriptionX1 (read only Text Field)
| ButtonXn | ButtonY1 | DescriptionXn
OutputRow looks like
| ButtonOutput | OutputField1 | OutputField2 | OutputField3 |
So I would like it to do
ButtonX1.click
OutputTable.OutputRow.addInstance(true) //this works - everything else I have questions on
OutputTable.OutputRow.OutputField1.rawValue = DescriptionX1.rawValue
Question 1
How do I address the location in each table to set a value
Question 2
How do I get the value of the description field in the same table and row as the button
I would like to say something to the effect of OutputTable.OutputRow[??].OutputField1.rawValue = this.parent.DescriptionX
OutputTable.OutputRow.OutputField2 = InputField.rawValue
Same question as above - how do I specify a dynamic row - is this the proper syntax for getting the value from the input field?
OutputTable.OutputRow.OutputField3 = this.ButtonLabel
Question 3
How can I get the value of the button's label to set in the field
There should be very many of these buttons and buttons will be added - I would prefer to set the value based on the button's label to make the value easier - not requiring changing the code
Question 4 - unrelated to those above.
Is it possible to build the first table
| ButtonX | ButtonY | Description |
from an XML File. I have seen examples of how to build if it is just data, but can the XML be pushed into a form with code to do the above actions?

Each object in a form must have a unique name. I doing so it is not neccessarily the name but the path or SomExpression associated with that object that must be unique. In your case you have a Table.Row.object configuration. The Row is the part that is repeating so to give each object a unique name an instance number is placed on the repeating part. So objects in the 1st row woudl be Table.Row[0].object...objects in the second row woudl be Table.Row[1].object etc .....You can see this by adding a debug instruction on the Enter event of the description field. Put the code app.alert(this.somExpression) and when you enter the field you will see what the somExpression is. Do this for a few rows and you will see the pattern (don't forget to remove the debug code from the enter event). Now you know what you have to use to address the fields. If no instance is given it is assumed to be 0 ..that is why only the 1st row is being affected.
So now to answer your questions:
Question1: The square bracket notation is an issue for javascript (this is the notation for an array) so we have to use a different means of addressing the field to include the instance number. So to address the Description in the 3rd row we woudl use:
xfa.resolveNode("Table.Row[2].Description").rawValue = "This is my new description";
Note that the instance number is 2 for the 3rd row because the instance numbers are 0 based.
Question2. The resolveNode notation allows you to pass a string so you can also concatinate expressions to make the string. If you are writing code on a button in the same row you can get the instance that you are on by using the expression this.parent.index. The "this" portion refers to the current object (the button) and the parent.index gets you th eindex of the Buttons parent. If the button is embedded deeper in a hierarchy then you can continue to add parent indicators until you get back to the node that you want. So rewriting your expression from Q1 it woudl be:
xfa.resolveNode("Table.Row[" + this.parent.index + "].Description").rawValue = "This is my new description";
Question3: The buttons caption can be retrieved by using ButtonName.caption.value.text.value
Question4: When you say build from an XML file. What are you expecting to come from the XML file? The caption that goes on the button? Typically the XML file carries data (not to say that it cannot carry other things). Just need a bit of clarification on this one first.
Hope that helps

You are trying compare String and int..! which is not possible try to case the txtIn.text to int using parseInt(txtIn.text).
ORIGINAL:
if(txtIn.text != ADD_TASK).---->error : Comparison between a value with static type String and a possibly unrelated type int
                    tasks.addItemAt(new Task(txtIn.text, 0, ""), e.rowIndex);----> error:Implicit coercion of a value of type String to an unrelated type int.
EDITED:

Dynamic rows in Table Control

Hi Experts,
My Requirement is create a table control with 5 coloumns. The rows have to be displayed dynamically...
I created a screen , and placed a table control.
For eg :

if internal table having say 40 entries , then the table control should have 40 rows...

How can I change the style of a row in tableview?

Hi,
How can I change the style of a row in tableview, for example ,I have 10 items in table view, and I'd like to change row 1,4,10 background-color:red; font-family:Arial ,Font-Weight:BOLD.
Any suggestion?

Yes, I knew how can I change the style using cell factory. there is a lot of work to do if it has so many columns in table view. we need to implement every cell factory, Do we have a simple way to change the whole row style , just like fabsav said, I 'd like to set the special row like this line:
tableview.getItems().get(i).setStyle("myRowstyle"); And I found a bug if I implement my functionality with cell factory way, I can't change the cell style after rendering cell.
protected void updateItem(Object object, boolean empty) {
super.updateItem(object, empty);
}updateItem() was only triggered while cell is being rendering, there is no way if I'd like to change the cell style after rendering event.
Hi fabsav, How can I apply a CSS class to a specific row? Can you please provide a short example?

Problem with tableview iterator

Dear friends.
I try to adopt tableview iterator in my customer's BSP pages. So, I programmed test page.
METHOD if_htmlb_tableview_iterator~render_row_start .
m_row_ref ?= p_row_data_ref.
ENDMETHOD.
M_ROW_REF is "Static Attribute" and "Public" and "Type Ref To Z3TYDISP"
z3tydisp has structure as below
REQNO NUMC 12
VGUBUN CHAR 1
DSCOFVGUBUN STRING 0
REQDT DATS 8
RNAME CHAR 10
VCOMP CHAR 30
VNAME CHAR 10
VPLACE CHAR 5
VPLACEDSC CHAR 20
APPROVAL CHAR 1
DSCOFAPPROVAL STRING 0
AND... p_row_data_ref has structure below
REQNO N 12
VGUBUN C 1
DSCOFVGUBUN g 0
REQDT D 8
RNAME C 10
VCOMP C 30
VNAME C 10
VPLACE C 5
VPLACEDSC C 20
APPROVAL C 1
DSCOFAPPROVAL g 0
In my option, p_row_data_ref has same structure compared with z3tydisp. But there is "CX_SY_MOVE_CAST_ERROR". How I have to define "z3tydisp"????

>>M_ROW_REF is "Static Attribute" and "Public" and "Type Ref To Z3TYDISP"
instead of this make your M_ROW_REF a instantaneous attribute. since static attribute are intantiated only once when object created and are shared by all other intances. m_row_ref contains data about the table you are going to render using tableview. so it should be public, so that get different data for different iterator objects.
your p_row_data_ref must be of type ref to data which is superior class of data types.
and if you have defined iterator "IF_HTMLB_TABLEVIEW_ITERATOR" in your interfaces. then you need not to define structure for p_row_data_ref, its already there in interface.
hope this will solve your problem,

Hi,
As Armin said use the following:
wdContext.nodeXXX().currentXXXElement().setAttributeValue("attributeName", value)
Here you give the value as value of simpleType and not its description.

when the submit button i clicked then the dynamic rows should be inserted.. Is this Swing coding? When I think of submit buttons, I usually think of Java Server Pages.
In other words, if possible, please clarify your question as details matter here. Also, showing the code you've tried would help too.
Good luck.
