How to set a column group by default on load and disable the group by option in rendering mode
.

Hi,

 You could define GroupDescriptor/ColumnGroupDescriptor initially as explained in our online documentation:

<telerik:RadGridView
                             Name="clubsGrid"
                             ItemsSource="{Binding Clubs}">
            <telerik:RadGridView.GroupDescriptors>
                <telerik:ColumnGroupDescriptor Column="{Binding Columns[\Name\], ElementName=clubsGrid}"
                             SortDirection="Descending"  />
            </telerik:RadGridView.GroupDescriptors>
</RadGridView>

Then, if you would like to disable user to group, you can set the IsGroupable property for each GridViewDataColumn to "False":

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" IsGroupable="False">

I hope this is what you need.
