I've been fiddling with the MVCRadGrid demo code, successfully adding column resizing and reordering.
Then I tried to add grouping. I added ShowGroupPanel="True" to my telerik:RadGrid tag,
GroupLoadMode="Client" to my MasterTableView tag, and AllowGroupExpandCollapse="True" AllowDragToGroup="True"
to my ClientSettings tag and Groupable="true" to my telerik:GridTemplateColumn tag

When I drag a column header to the GroupPanel I get an "Object expected" Javascript error in this code

__doPostBack(

'ctl00$MainContent$RadGrid1','FireCommand:ctl00$MainContent$RadGrid1$ctl00;GroupByColumn;TemplateColumn4')

 


The doPostBack is suspicious. This is MVC, there is no such thing. What am I doing wrong?

Also, if I set EnableHeaderContextMenu to true for the RadGrid, I get an error about type "CheckBox" must be
placed inside a form tag. I suspect there is something in the default context menu which uses an asp:checkbox, which, again, is not compatible with MVC. Is there a way to make this work in MVC?

Hello Frank,

Unfortunately RadGrid features like grouping, filtering, header context menu, etc. are strictly dependant on regular postbasks and currently are not supported in ASP.NET MVC. See this topic from the documentation for more details.

Kind regards,
