Not able to select a row in ALV in Webdynpro

[former_member188736]

Hi everyone,

I have developed a webdynpro application and I have declared component usage for SALV_WD_TABLE.

The data gets displayed in the ALV, but always the first row is selected.

When I try to select another row,I am not able to select.

Could anyone please suggest what might be the problem ?

Thanks in advance.

Hi Kumudha,

After going through all replies, I think ur looking for a Application Just similar to

Web Dynpro Component : WDT_ALV

Description : Sample solution for tutorial ALV in Web Dynpro A

Web Dynpro Component : WDR_TEST_DYN_ALV_USAGE

Description : Web Dynpro Application wdr_test_dyn_alv_usage / Component WDR_TEST_DYN ALVUSAGE

Here U can check, for selection of rows in ALV.

Note: To see this in your system please do activate these services

sap/bc/webdynpro/sap/wdt_alv and sap/bc/webdynpro/sap/wdr_test_dyn_alv_usage in T-code SICF

if still ur not getting the requested result then, it is due to Patch Update in your SAP S/m.

Hi Kumudha,

Just check the selection property of the node (which you have binded to the data node of the ALV component) to 0:1 or 0:n.

Hi Arjun,

I have set the selection property of the node to '0:n'.

I haveeven tried changing this to '0:1', but it didnt work in both the cases.

And cardinality I have set to '1:n'.

Please suggest.

Hi,

If u are having the selection property as 0:n and cardinality as 0:n then it should work. Plz check it once again.

Please check if u have done something wrong in coding.

First row may be selected because you must have set Initialize Lead Selection to True in your context node bound to ALV.

Other is you have to set the Row selectable property of ALV to true using the below code

• SET row selectable as true

CALL METHOD LR_FUNCTION_SETTINGS->IF_SALV_WD_TABLE_SETTINGS~SET_ROW_SELECTABLE

EXPORTING

VALUE = ABAP_TRUE.

where LR_FUNCTION_SETTINGS is TYPE REF TO CL_SALV_WD_CONFIG_TABLE.

Hope you got the idea.

Hi Manas,

I have tried to add the code you have given in the "WDDOINIT" method of the view being used.

But , the row didnt get selected.

Please suggest.

Hi,

As said above cardinality should be 0..n as your alv can have 0 or N rows.

Selection can be 0..1 or 0..N based on your scenario.

Can you paste the piece of code you have written, so that we can try to figure out if something is wrong.

Ideally, with above mentioned steps it should work.

Hi

Simply replace lr_function_settings with l_value.

You already have a referenc to alv model class.

check it then

[former_member188736]

Hi Manas,

I have checked replacing with l_value, but no change.

The row is still not getting selected.

Please advise.

Lets wait for Thomas's input then..

It should work with above mentioned checks.

Try creating a new ALV and see if it behaves the same.
