Select All values option for Check box group/List Box in Design Studio

[ssurampally]

Hi,

I have got a requirement to provide a button to check all values option for a check Box group/ListBox component in Design Studio, version 1.6 SP 3. I have applied CSS code as described below to a button on click event.

It is not working as described in the above discussion, tried with placing internal key and external key, did not work.

Later I changed the Source values of the Check box group from data Binding DS_1(on HANA view) to fixed values, check all button works fine.

I also checked the SAP note described in the same discussion, limitation with data binding option for select members API. followed the correction, of making the follow filter state to 'false'. did not help either.

2193693 - Limitations of the Design Studio Property Binding Feature.

I am not sure, what could be the issue? can you please assist

Thanks
