Delete button in ALV Table

Hi,
Does any one have a code sample for the ALV Table Delete button? When I hit the DELETE button the selected row gets deleted but how can I save this deletion to the database table so that when I do a refresh the deleted row does not re-appear.
Thanks. Kim

Hi Kim,
i am sorry but I dont have a sample code for this .. but yes i can tell you a very simple logic here that should work fine ..
When the user clicks on Delete Entry call method say "Delete_entry" and within this you can write code based on this logic..
1) On_Action_Lead_Select should copy the content of that row to another context node say "Selected_Entry"
2) Search for this entry in your internal table/database that was bound to the ALVs context node(data source) and remove it using standard functions
3) again read the database/internal table data and bind it to the context node ..
Your changes will be reflected in your ALV..
I hope this helps and if it does please do award points
Also please close the thread if the issue gets resolved ..
Regards,
Anoop

Disable delete button in ALV grid

Hi Experts,
I have a functionality to disable some buttons in alv grid such as delete row,cut,print etc.
I know how to exclude them by using it_toolbar_excluding , but I need to disable them.
Can you please let me know how to handle this.
I am displaying the ALV grid by calling the method set_table_for_first_display.
Thanks in Advance
Prasanth

Hi,
By using below code you can disable any button in ALV display
data : tool_wa_exclude type ui_func.
tool_wa_exclude = cl_gui_alv_grid=>mc_fc_loc_delete_row.
append tool_wa_exclude to tool_it_exclude .
call method grid2->set_table_for_first_display
    exporting
      it_toolbar_excluding          = tool_it_exclude
    changing
      it_outtab                            = it_ekpo
      it_fieldcatalog                    = it_fcat
    exceptions
      invalid_parameter_combination = 1

      others                                        = 4.
U need to pass tool_it_exclude internal table to method for displaying

Rendering Delete button in the table

Hi,
I have created a column in the table and dropped the delete operation in that column.
My case is that whenever the create insert button is clicked a new row is added to the table and only to that row the delete button should be rendered, all the other older rows the delete button should not be rendered.
This is similar to the advanced search option in the adf, when we add fields we will get a delete button at end of each field.
How to implement the same case in the table ?

I have given set property listener to create insert button and named to be 'new', then in the rendering condition of the delete button i gave as #{pageFlowScope['return']=='new'}. so initially the delete button is not rendered in the existing rows in the table but when create insert button is clicked delete button is rendered in all the existing rows and also in the newly created row.
Am not sure whether this is the right approach.

Replacing SAP Object Selector with Radio Button in ALV table in WD ABAP

Hi All,
I have a view in Webdynpro ABAP which displays data in an ALV table view (using SALV_WD_TABLE component).
By default we have the SAP Object Selector for selecting a particular row of the table. This has to be replaced with radio buttons.
I mean instead of using the SAP Object Selector, I need radio buttons at the start of each row.
What I have thought of is to make the SAP Object Selector Invisible and create another attribute for the radio button in the node which contains ALV output data.
Can you please let me know how to remove the SAP Object Selector from ALV output table and also how to include a column with radio button in the ALV output table.
Thanks and Regards,
Sayan Ghosh

Hi Lekha,
I am working with HRASR00_PROCESS_EXECUTE WD component of MSS application. In order to generate the data, this in turn calls another component called DATAOBJECTPROVIDER. I need to make the table selection as none and replace the SAP Object Selector with the radio button.
Do you know under which method in DATAOBJECTPROVIDER do we need make the changes. I tried to search all the methods but couldnt understand a suitable one.
Thanks and Regards,
Sayan Ghosh

Keyboard delete button and alv response

Hello friends,
I have a problem with editable alv.
In alv grid if i select a line and press the delete button on the keyboard, then the data is getting deleted.
i do not want that to happen.
how can i stop it from happening?
Note: I am not talking about the delete icon which alv provides. I mean the DELETE BUTTON ON THE KEYBOARD

I know what you mean, but surely when you are typing it makes sense to have a backspace key and not delete as the cursor is ahead of the error.
Also, a simple tap on the screen at the place you want to edit also means that you can position the cursor after the error. Then, again, you can use the backspace key.
Personally, I have never felt the need for a delete key, but you should leave feedback for Apple at http://www.apple.com/feedback/ipad.html
I presume you are aware that if you hold your finger on the screen that you can move and select text anywhere on the screen.

Custom Button in ALV table

Hi Experts,
I have created a custom button 'SELECT' in ALV table toolbar.
lo_function = l_value->if_salv_wd_function_settings~create_function( 'SELECT' ).
Now i am getting position of this custom button next to the Standard buttons ('Print' and 'Export' ). So how do I change the custom button position to first place. I mean the custom button should be in the left most position in the toolbar.
Please help me in resolving this.
Regards,
Sarathy.

Thank you Lekha. Set_position is working.
We have to change the positon of custom button and the standard button. So that the position of button gets interchnaged.

Sarathy

Deleting rows in a table with a button

Good Day All;
I seemed to have run into a snag with trying to add a delete button in a table that will delete a row. Let me expain.
The form has 1 table that has 7 cells made up of text fields and drop downs. This table is in its own subform.
There is a button to add rows as the user requires. The code I am using to add rows: psl_list_subform.instanceManager.addInstance(1);
I have been asked to add a delete button so a user can delete rows. I have added this to the end of the table. SO each time a row gets repeated, there is a delete button. The code I am “trying” to use is;
Table4.Row1.instanceManager.removeInstance(this.parent.index);
When I click on the button to delete, nothing happens. I brought up the JavaScript debugger, there are no errors.
Any ideas what I missed.
Thanks All
Chomp

Hi,
from my understanding of your form, you adding new instances of the subform "psl_list_subform" which contains a single table row.
The hierarchy that will look like "psl_list_subform.Table4.Row1.RemoveButton".
To remove an instance of the subform, from a button within the table row the script needs to refer to the 3rd parent of the remove button.
this.parent.parent.parent.instanceManager.removeInstance(this.parent.parent.parent.index);
Explaination: this = RemoveButton, 1st parent = Row1, 2nd parent = Table4, 3rd parent = psl_list_subform

How to disable delete button of UITableView automatically appears when it i

Hi,
My app has a UITextField on a UITableViewCell, and having a trouble with editing text in the UITextField.
When I am going to edit the text, first I tap the UITextField, then a loupe appears, and it should follow the move of my finger.
But when I move my finger intending to move the loupe, UITableView misunderstands the gesture and show a delete button on the table view. And once the delete button appears, it blocks control to the loupe and the loupe freezes.
As table row can be deleted just by turning UITabeView's editing YES, there is no need to display delete button in my application when the table view is swiped, and I need to disable this function of UITableView.
Are there any ways to prevent delete button from appearing?

Its in my TableViewController which also acts as my delegate method.
// FavouritesViewController.h
#import <UIKit/UIKit.h>
@interface FavouritesViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> {
IBOutlet UITableView *favouritesTable;
@property (nonatomic, retain) UITableView *favouritesTable;
the "myTable" reference is the reference to my tableview. So with the example above I have the following in my FavouritesViewController.m:
#pragma mark Table Edit Delegate Methods
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
[super setEditing:editing animated:animated];
[favouritesTable setEditing:editing animated:YES];
Hope this helps. Regards, Michael.

Removing "print version" button in alv

How to delete a particular row in ALV table

Hi,
How to delete a particular row in ALV table based on some condition(by checking value for one of the columns in a row)
Thanks
Bala Duvvuri

Hello Bala,
Can you please be a bit more clear as to how you intend to delete the rows from your ALV? By the way deleting rows from an ALV is no different from deleting rows from a normal table. Suppose you have enabled selection property in ALV & then select multiple rows and click up on a button to delete the rows then below would be the coding: (Also keep in mind that you would have to maintain the Selection property of the context node that you are binding to your ALV to 0..n)
data : lr_table_settings TYPE REF TO if_salv_wd_table_settings,
             lr_config          TYPE REF TO cl_salv_wd_config_table.
lr_table_settings ?= lr_config.
** Setting the ALV selection to multiple selection with no lead selection
lr_table_settings->set_selection_mode( value = cl_wd_table=>e_selection_mode-multi_no_lead ).
Next delete the selected rows in the action triggered by the button:
METHOD onactiondelete_rows .
DATA: wd_node TYPE REF TO if_wd_context_node,
         lt_node1 TYPE ig_componentcontroller=>elements_node,
         wa_temp TYPE REF TO if_wd_context_element,
         lt_temp TYPE wdr_context_element_set,
         row_number TYPE i VALUE 0.
wd_node = wd_context->get_child_node( name = 'NODE' ).
CALL METHOD wd_node->get_selected_elements
    RECEIVING
      set = lt_temp.
LOOP AT lt_temp INTO wa_temp.
    wd_node->remove_element( EXPORTING element = wa_temp ).
ENDLOOP.
CALL METHOD wd_node->get_static_attributes_table
    EXPORTING
      from = 1
      to    = 2147483647
    IMPORTING
      table = lt_node1.
wd_node->bind_table( new_items = lt_node1 ).
ENDMETHOD.
If in case this isn't your requirement please do let me know so that I can try come up with another analysis.

Hi
ALV table will be shown in the viewcontainerUI element.
it is shown there empty if you dont fill the node bound to the data node of the interface controller of the comp usage
SALV_WD_TABLE.
and if you are not getting the table filled in the first place.
then check have you mapped the DATA node to some node in the comp controller
wht basically is your requirment is that you want to show ALV gird on click of one button and delete it on click of other button.
there are many ways to do so.
best way is control the visiblity of the viewcontainer UI element which containes the TABLE view of SALV_WD_table comp.
create an attribute of type WDUI_VISIBILITY name say VIS.
now go to the layout and bound hte visible property of the viewcontainer to this attribute VIS.
then in the showalv grid button's eventhandler write
wd_context->set_attribute(
name = 'VIS'
value = '02'
and in the wddoinit and delete alv grid button's event handler write
wd_context->set_attribute(
name = 'VIS'
value = '01'
thanks

Disable delete button in Table Maintainance Generator

Hello all,
How to disable delete button in Table maintainance generator???

Hi Maya,
It is very interesting question. If you debug your table maintenance screen, the program of table maintenance screen will not have statically defined pf status. So you cannot exclude delete functionalities using the below statement.
SET PF-STATUS <the GUI status> EXCLUDING 'DELE'.
For viewing pf status SAP has programmed in dynamic manner using this FM VIEW_SET_PF_STATUS.
Before calling above FM you need to exclude delete function. Follow the following step for achieving this
Go to sm30. Put your table name and press on maintain push button. It will display table entries in maintenance screen.
Go to system->status
Click on program name.
Go to your flow logic of you table maintenance screen number.
It will have following code in flow logic
