I have requirement inside row expand table grid Multiselect control not working. I have seen some articles saying expected behavior. anyone face similar issue and is there any work around please let me know it’s really helpful to achieve my requirement.
@Mr.Kusuma This happens because the MultiSelect control is a template-only control, but the master-detail expanded row in a Table/Grid is rendered in non-template mode, so the control never initializes.
Fix it by forcing the table to run in template mode: open the Table Layout properties and enable Optimize for mobile (this switches the grid to template rendering).
After that, set the table’s data source to a Data Page (template tables require a Data Page source).
Keep your MultiSelect inside the expanded details section as-is, but make sure it uses the same row page context.
Once the grid is template-rendered, the MultiSelect will display and work normally inside the expanded row.
