    Hello,

    The Update command does not work when I try to update values inside a RadGrid that resides inside a UserControl.  

    The UserControl is loaded into a TabStrip tab when the tab is clicked by the user.  This is the code that loads the user control:

    parent.Controls.Clear();
    UserControl ctrl = (UserControl)LoadControl(controlName);
    string userControlID = controlName.Split('.')[0];
    userControlID = userControlID.Replace("/", "").Replace("~", "") + "_UC";
    ctrl.ID = userControlID;
    parent.Controls.Add(ctrl);

    I'm using Advanced Databinding for the Radgrid like so:

    protected void rgdHousingVersion_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
    {
        rgdHousingVersion.DataSource = BLL.GetAHUHousingVersions();
    }

    And here's the HTML for the UserControl:

    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
     
    <telerik:RadAjaxManagerProxy ID="rampAdminHousingVersion" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="rgdHousingVersion">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rgdHousingVersion" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManagerProxy>
     
    <telerik:RadGrid ID="rgdHousingVersion" runat="server"
        OnNeedDataSource="rgdHousingVersion_NeedDataSource"
        OnEditCommand="rgdHousingVersion_EditCommand" OnUpdateCommand="rgdHousingVersion_UpdateCommand"
        AutoGenerateColumns="false"
        AllowPaging="false">
        <MasterTableView DataKeyNames="HousingID" CommandItemDisplay="Top" InsertItemPageIndexAction="ShowItemOnCurrentPage" EditMode="InPlace" EnableViewState="true">
            <Columns>
                <telerik:GridEditCommandColumn ButtonType="ImageButton" EditImageUrl="~/Images/Graphics/16/Change_16.png"></telerik:GridEditCommandColumn>
                <telerik:GridBoundColumn DataField="HousingID" HeaderText="Housing ID" UniqueName="HousingID"></telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="Description" HeaderText="Description" UniqueName="Description"></telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="Reference" HeaderText="Reference" UniqueName="Reference"></telerik:GridBoundColumn>
            </Columns>
            <EditFormSettings>
                <EditColumn ButtonType="ImageButton" />
            </EditFormSettings>
        </MasterTableView>
    </telerik:RadGrid>

    Here's the code-behind for the OnEditCommand and OnUpdateCommand:

    protected void rgdHousingVersion_EditCommand(object sender, GridCommandEventArgs e)
    {
        //Does fire
    }
     
    protected void rgdHousingVersion_UpdateCommand(object sender, GridCommandEventArgs e)
    {
        //Does NOT fire
    }

    I'm really not sure what I'm doing wrong.  Why is the UpdateCommand not firing?  Any help is appreciated.  I have not been able to find an answer to this problem anywhere.  Thanks!

    Hi Shawn,

    I examine the provided code but I am not sure on which event you add the user control dynamically. Keep in mind a suitable event is PageViewCreated as demonstrated in the following help article.
