OnRender didn't call

I am using the RadzenDataGrid with AllowGrouping="true", and I also added the Property Render="@OnRender", but the method OnRender didn't get called.

On my data grid, I can drag the column hearder to the group area, but the column header doesn't who whey I drag the header. What was worst, when I drop (with nothing showing) to the group area, grouping isn't happening.

I'd appreciate if you could help.

Thanks.

I can’t tell much just by this description - try to prepare runnable code demonstrating your case. You can use our demos - they are editable.

Thanks @enchev for getting back to me. I have attached my case in the zip format in the reply.

I also found out that I can't find out that I can't start individual item in the grid by clicking the styled "START" button. The call to the function on the razor side didn't get called either

Make sure you've enabled interactivity:

Thanks @enchev, that partially fixes the issue. One important issue is that I didn't have @rendermode InteractiveAuto turned on my Razor page. Together with your suggestion, it works fine now. I'd appreciate your prompt response.

Actually, if I downgrade the Blazor's Client/Server project back to .net8 and it stops working. It seems that it only works for .net9 ????

Never mind, I do a deep clean and wiped out the bin areas for both client/server side for my .net8 testing, and it seems to be working fine. Thanks @enchev.

Hi @enchev,

I saw that the datagrid would highlight the row when the mouse hover, and the selected row changes colors. But, on my implementation, it didn't do that artifacts. Can you let me know how I can add it?
