Describe the bug
Datagrid places the GroupFooter in the wrong column when combining expandable rows with a grouping column.

To Reproduce
Steps to reproduce the behavior:

  1. Create a datagrid, ensure it has AllowGrouping="true"
  2. Create a Template for the datagrid (triggering expandable behavior, requires no content)
  3. Add a datagrid column and give it a GroupFooterTemplate.
  4. Add a second datagrid column, ensure Groupable="true".
  5. Run the blazor app, navigate to the datagrid page.
  6. Group by dragging the groupable column title to the datagrid header.
  7. The GroupFooter is placed in the wrong column.

Expected behavior
Expectation is that the GroupFooter is placed in the column (RadzenDataGridColumn) for which the corresponding GroupFooterTemplate it was specified.

Thanks for your attention. Your screenshots show that a FooterTemplate works correctly. I can confirm it does, since I use it elsewhere in my application. That is however not the problem I described and is (as far as I can tell without diving into the code) completely unrelated to the bug I reported.

If you take the above code, add a Template to the datagrid (or otherwise force the rows to be expandable), and add a GroupFooterTemplate instead of, or in addition to a FooterTemplate, then you should see the problem.
