Class CL_WDR_ALL_IN_ONE_UTIL

[Former Member]

Hi all!,

I´m just a begginer at WDA and I´m facing a problem that I can not go through it. I hope someone of you could help me because I´m in a hurry.

I have a table (normal table not a ALV) in a view, and I have to control when the user select one table entry (just one). I know about the OnLeadSelect event in the table, I´ve implemented it, I´m able to retrieve the exact register selected... and so on. But after processing, the table has always displayed as selected (dark yellow) the first register.

I´ve already dubugged several times WDR_TEST_TABLE application at SAP standard.

So, my cuestion is: is it mandatory to implement the CL_WDR_ALL_IN_ONE_UTIL class to use the OnLeadSelect event in a table?. I don´t really think so, but ... i´m a bit lost.

Thanks a lot for your help!!

Hi beatriz,

Lead selection is initialized automatically for each newly created context node.

you can also manually set the lead selection

Manual initialization of lead selection-If automatic initialization was deactivated, the lead selection can be programmed manually. In this case it is possible to assign this property to an element other than the first element of a node (for example, using an index).

Hi!,

Thank you all for your answers. Now it is working!!!

The class CL_WDR_ALL_IN_ONE_UTIL is not mandatory. When I knew that I focused in other part of the code. And then, thanks to Anand Prakash Rai answer I started to think that I was re-creating muy context again and again.

And that was the answer!. I had the binding part at WDMODIFYVIEW method, I don´t know exactly why, but when I changed it to other even it started to work.

Thank you very much!!

Hi ,

No class needs to be implemented .

if you want to change your lead selection as such you can use the methods

SET_LEAD_SELECTION_INDEX Set Element of Lead Selection with Index

SET_LEAD_SELECTION Set Element of Lead Selection with Index

MOVE_FIRST Set Lead Selection to First Node Element

MOVE_LAST Set Lead Selection to Last Node Element

MOVE_NEXT Set Lead Selection to Subsequent Node Element

MOVE_PREVIOUS Set Lead Selection to Previous Node Element

MOVE_TO Set Lead Selection to Specified Node Element

where you can change your lead selection.

hi ,

is it mandatory to implement the CL_WDR_ALL_IN_ONE_UTIL class to use the OnLeadSelect event in a table?.

no the class is not mandatory

just change the SELECTION MODE property of UI to single

refer the SAP online help

hi,

Change the Selection mode property of Table to Single.

Now you will be able to select only one row in a table.

For getting the selected row, i think you have already implemented Lead Selection Event.

No class needs to be implemented to use Lead Selection Event.
