Hello,

I have a RadGrid with a simple definition, automaticinsert and update allowed:

    
            <telerik:RadGrid ID="MainGrid" runat="server" SkinID="Admin" AllowPaging="True" AllowAutomaticInserts="True" 
        
              AllowAutomaticUpdates="True" DataSourceID="ObjectDataSourceMain"> 
        
              <MasterTableView DataKeyNames="Id"> 
        
                <Columns> 
        
                  <telerik:GridBoundColumn HeaderText="Název katalogu" DataField="Name"> 
        
                  </telerik:GridBoundColumn> 
        
                  <telerik:GridBoundColumn HeaderText="Rok" DataField="Year"> 
        
                  </telerik:GridBoundColumn> 
        
                  <telerik:GridCheckBoxColumn HeaderText="Aktivní" DataField="IsActive"> 
        
                  </telerik:GridCheckBoxColumn> 
        
                </Columns> 
        
              </MasterTableView> 
        
            </telerik:RadGrid> 
        
            <asp:ObjectDataSource ID="ObjectDataSourceMain" runat="server" OldValuesParameterFormatString="Original_{0}" 
        
              SelectMethod="GetCatalogs" UpdateMethod="UpdateCatalog" InsertMethod="CreateCatalog" 
        
              TypeName="Kooperativa.KoopObchod.Facade.ProductFacade"> 
        
              <UpdateParameters> 
        
              </UpdateParameters> 
        
              <InsertParameters> 
        
              </InsertParameters> 
        
            </asp:ObjectDataSource>

Everything works fine till RadAjaxManager is added:

    
            <telerik:RadScriptManager ID="RadScriptManager" runat="server" />
        
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
              <AjaxSettings> 
        
                <telerik:AjaxSetting AjaxControlID="MainGrid"> 
        
                  <UpdatedControls> 
        
                    <telerik:AjaxUpdatedControl ControlID="MainGrid" /> 
        
                  </UpdatedControls> 
        
                </telerik:AjaxSetting> 
        
              </AjaxSettings> 
        
            </telerik:RadAjaxManager>

Then I get client error:

"Line: 6
Error: Sys.WebForms.PageRequestManagerServerErrorException: Exception has been thrown by the target of an invocation."

Insert works fine. This problem occured on all my grids.

How to find the problem? Thank you
