hi,

when you have your event,

you can find your selected element in context_element in wdevent

so you wont need the index

grtz,

What I meant was, how are you creating a new row? If you have 5 rows already, you will create a 6th by appending an empty row right? In which case, your index will be 6. This is what i meant in the previous post.

Otherwise, I dont think you can get the index directly without a lead selection. You can only get the element by wdevent->get_context_element( 'CONTEXT_ELEMENT' ). You can then get the data in the row by using get_static_attributes on the element. After which you should probably loop, do a field compare and only get the index.

As I said earlier, it is not possible to get the index. You can only loop and get the current index by doing a field comparison. That too will fail if you have two identical rows.

A better idea would be to have your table as read-only. Have a 'Display/Change' button in your toolbar. You should be able to select a row and click on 'change'. Then you should make the row as editable and do your validations on the edited values. If you have your entire table as editable, it will not be easy to track the changes.

Otherwise, if you want to have the table as editable only, then you can get the changed values using the context change log. Refer to web dynpro component DEMO_CONTEXT_CHANGES to see how this works. You will not get the index, but you will get all the changes that have been done to the context after the last binding.

Hi Setu,

pls make the below call using the reference to your node to which the Table is Bound.

• get Index of selected table item

CALL METHOD NODE_NAME->GET_LEAD_SELECTION_INDEX

RECEIVING INDEX = Lv_Indx.

( DATA: Lv_Indx Type i )

This should definitely solve the Problem.... If so.. Points

Thanks,

Phani M.

PS: reach me if u have any issues./.

Hi Setu,

No problem. you can call the method i mentioned within "OnAction Enter" event handler method. This should work in the way you desire.

Hi Setu,

Ideally, when u create a New Row, We need to select tht row & then do any further processing. So, user should select the new row first, the press Enter which solves the issue.

There might be some other work-around, but this is my preferred solution.

Thanks,

thank u phani .

but due to some logic in my application we r not using lead selection .

so its not possible to depend on this lead selection .

so pl tell me if any other solution for this problem .

thank u .

Hi,

I assume you will be creating a new row by appending an empty row to your internal table and bind it to the context again. The index in this case will simply be the last line in your table.
