I have implemented a test using the related grid example.  My difference is that I have an edit command column and a template for the edit form.  All the grids are updated via AJAX.  The grids interrelate correctly, but when clicking on the edit button or add record link the form doesn't display.  If I turn off AJAX the form displays, but the application slows down significantly.


Code behind:


Protected Sub grdFacilities_ItemCommand(ByVal source As ObjectByVal e As GridCommandEventArgs) Handles grdFacilities.ItemCommand  
If e.CommandName = "RowClick" Then 
    Dim id As Integer = Int32.Parse(e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("ID"))  
    lblStatus.Text = "Selected Facility ID " & id  
    lblStatus.Text = "e.CommandName = " & e.CommandName  
End If 
End Sub 

ASPX grid code:

<telerik:RadGrid ID="grdFacilities" runat="server" GridLines="None" DataSourceID="FacilitiesGridObjectDataSource"   
     OnItemDeleted="grdFacilities_ItemDeleted" OnItemInserted="grdFacilities_ItemInserted" OnItemUpdated="grdFacilities_ItemUpdated"  OnItemCommand="grdFacilities_ItemCommand" 
     AllowMultiRowEdit="True" AllowAutomaticDeletes="True" AllowAutomaticInserts="True" AllowAutomaticUpdates="True" > 
     <MasterTableView DataKeyNames="ID" AutoGenerateColumns="False" DataSourceID="FacilitiesGridObjectDataSource" EditMode="PopUp" 
          CommandItemDisplay="Top" NoMasterRecordsText="No facilities on file"  > 
               <telerik:GridEditCommandColumn ButtonType="ImageButton">  
                    <ItemStyle CssClass="MyImageButton" /></telerik:GridEditCommandColumn> 
               <telerik:GridBoundColumn DataField="ID" ReadOnly="True" HeaderText="ID" DataType="System.Int32" UniqueName="ID">  
                    <ItemStyle ForeColor="Gray" /></telerik:GridBoundColumn> 
               <telerik:GridBoundColumn DataField="FacilityName" ReadOnly="True" HeaderText="Facility" UniqueName="FacilityName" ></telerik:GridBoundColumn> 
               <telerik:GridButtonColumn ConfirmText="Delete this Facility?" ConfirmDialogType="RadWindow" ConfirmTitle="Delete" ButtonType="ImageButton" 
                    CommandName="Delete" Text="Delete" UniqueName="DeleteColumn">  
               <ItemStyle HorizontalAlign="Center" CssClass="MyImageButton" /></telerik:GridButtonColumn> 
          <EditFormSettings EditFormType="Template" PopUpSettings-Width="587px">  
                    <table id="Table7" cellspacing="1" cellpadding="1" width="350" border="0"><tr><td>Name</td> 
                         <td><asp:TextBox ID="txtFirstName" runat="server" Text='<%# Bind( "FacilityName" ) %>'></asp:TextBox></td></tr> 
                    <asp:ImageButton ID="btnUpdate" runat="server"    
                         ImageUrl="images/saveBtnBg.gif" CommandName='<%# IIf( DataBinder.Eval(Container, "OwnerTableView.IsItemInserted"), "PerformInsert", "Update") %>'>  
                    <asp:ImageButton ID="btnCancel" runat="server" 
                         ImageUrl="images/cancelBtnBg.gif" CommandName="Cancel"></asp:ImageButton> 
               <EditColumn UniqueName="EditCommandColumn1">  
          <FormCaptionStyle BorderColor="White" BorderStyle="None" ForeColor="Black" /></EditFormSettings>  
          <CommandItemSettings AddNewRecordText="Add Facility" /> 
     <HeaderContextMenu EnableTheming="True" Skin="Vista">  
          <CollapseAnimation Duration="200" Type="OutQuint" /> 
     <ClientSettings enablepostbackonrowclick="true">

Hello Ken,

Unfortunately we could not reproduce the issue which you described. In my test all grids are ajaxified and the edit form popped up every time. I used all the settings from your code example. Also please verify that RadAjaxManager has correctly defined ajax settings.

If the problem persists, I suggest you examine the attached test project and modify it in order to reproduce the problem. Thus I will do my best to assist you further in resolving it.

Best regards,

In case anyone else runs into the problem.  My error was not having a reference to the top grid in the AJAX for that same grid.  Once added everything worked correctly.  All the examples just had edit links in the second grid, my problem was in the top grid only.  Thanks to Telerik support for their assistance.
