GroupBy (EnableGroupCheckBox) doesn't work with virtualization

[Francisco Fernandes]

Good afternoon, 

I'm using the multiselect component and virtualize doesn't work when I have groupby and EnableGroupCheckBox=true. Without EnableGroupCheckBox it shows the data but with EnableGroupCheckBox=true it doesn't. I tried it with your samples and got the same result (images inside zip folder).

Any help with this problem would be appreciated.

Hi  Francisco Fernandes,

We have included the fix for the issue “Exception occurs and data is not loaded properly on open the popup when virtualization is enabled” with our package version “29.1.41”. Therefore, we recommend upgrading to our latest version to resolve the current issue.

Rootcause:

The issue occurred when attempting to open a popup with virtualization enabled, as the code was searching for data in the wrong location. Initially, it utilized the general list data source (ListDataSource) and standard field references (this.Fields.GroupBy), which do not function correctly when virtualization is active.
