RadGrid client side toggle selection with server side persisting of the selected items after Sorting, Filtering and Paging

[Shumaila Imran]

My problem is related to this Code Library solution for Row Selection Persistence on Paging & Filtering.

The header checkbox does not work if Grouping is enabled in the RadGrid and/or there is another RadGrid nested within in the outer RadGrid.

I've added the Group Expressions and NestedViewTemplate in the code sample to reproduce the problem. Could anyone please mention the reason why the header selection does not work in this code sample with Grouping and NestedViewTemplate ?

<telerik:RadGrid ID="RadGrid1" runat="server" Skin="Outlook" AllowSorting="true" AllowPaging="true"
           AllowFilteringByColumn="true" AutoGenerateColumns="false" ShowGroupPanel="true" PageSize="6" >
           <MasterTableView DataKeyNames="ID">
                <GroupByExpressions>
                      <telerik:GridGroupByExpression>
                          <SelectFields>
                                 <telerik:GridGroupByField FieldAlias="Public" HeaderText="Grouped by Public & Private Questions"  FieldName="ID" />
                           </SelectFields>
                           <GroupByFields>
                                 <telerik:GridGroupByField FieldName="ID" FieldAlias="Public"    />
                           </GroupByFields>
                        </telerik:GridGroupByExpression>

Hello Shumaila,

You may consider using the example from this code library thread as starting points for your implementation:
