[Solved] InsertCommand and ItemCommand not firing for grid inside FormTemplate

[Stephen]

Hi all,

I have a RadGrid inside the FormTemplate of another RadGrid.  My markup looks like this at the moment:

<telerik:RadGrid ID="CollectionsRadGrid" runat="server"
    OnNeedDataSource="CollectionsRadGrid_NeedDataSource"
    OnItemCommand="CollectionsRadGrid_ItemCommand"
    OnItemCreated="CollectionsRadGrid_ItemCreated">
    <MasterTableView DataKeyNames="CollectionID" AutoGenerateColumns="false" CommandItemDisplay="Top" EditMode="EditForms">
        <CommandItemTemplate>
            <telerik:RadToolBar ID="CollectionsRadToolBar" runat="server" AutoPostBack="true">
                <Items>
                    <telerik:RadToolBarButton Text="Add a new collection" ImageUrl="/Public/Images/icon-add.png" CommandName="InitInsert" />
                </Items>
            </telerik:RadToolBar>
        </CommandItemTemplate>
        <Columns>
            <telerik:GridBoundColumn HeaderText="Reference" DataField="Reference" ReadOnly="true" />

        </EditFormSettings>

and my code behind is as follows:
The function at the very bottom (in bold) is where I am having the problem.  It is not being executed.

Found the problem myself:

Commented this function out - now works as expected

///// <summary>
///// Collections radgrid item created event
///// </summary>
///// <param name="sender">The sender</param>
///// <param name="e">The event args</param>

//    }
//}
