    My scenarion is like this, I need to open a radWindow on click of a Imagebutton which is in radGrid dyanamically (server side)


    for that I written code to open radwindow in ItemCommad event of radGrid


    my problem here is, when I click first time on a Image in radgrid,the debugger passes through the code, the page refreshes and window is added to controls (here the window doesn't open) and when I click on the same image second time the window opens (because the winow is already added to the controls, here the debugger won't go into the code again )


    I want to open the window on single mouse click of a image (I want to do this on item command event because I need to pass some value to radwindow on click of a imagebutton), How can I achieve this?

    muy code is as follows

    protected void rdgSystemGrid_ItemCommand(object source, GridCommandEventArgs e)





                    if (e.CommandName == "Comments")


                        Telerik.Web.UI.GridDataItem item = e.Item as Telerik.Web.UI.GridDataItem;


                            ImageButton imgComment = (ImageButton)item["comments"].FindControl("imgComments");





    private void ShowWindowPopUp(ImageButton imgComment)//, string systemId)



                RadWindow window = new RadWindow();

                window.EnableEmbeddedSkins = false;

                window.Title = "Add Comments";

                window.Skin = "Default";

                window.ShowContentDuringLoad = false;

                window.VisibleStatusbar = false;

                window.ReloadOnShow = true;

                window.Behaviors = WindowBehaviors.Reload | WindowBehaviors.Close | WindowBehaviors.Move;

                window.Modal = true;

                window.Width = Unit.Parse("500px");

                window.Height = Unit.Parse("450px");

                window.OpenerElementID = imgComment.ClientID;


                window.NavigateUrl = @"~/obt/Dashboard/Comments.aspx";





    <telerik:GridTemplateColumn UniqueName="comments" HeaderText="Comments" ItemStyle-Width="200px" >


                            <asp:ImageButton ID="imgComments" CommandName="Comments" runat="server" ImageUrl="/comments.gif "/>

    Hello Ram,

    Try setting VisibleOnPageLoad property of RadWindow to True and see whether that makes any difference.

    private void ShowWindowPopUp(ImageButton imgComment)//, string systemId) 
          RadWindow window = new RadWindow(); 
              . . . 
          window.Height = Unit.Parse("450px"); 
          window.VisibleOnPageLoad = true
              . . .

    I want to open a radwindow when user clicks a button ("Select") in a radgrid.

    Is there a complete example available?

    I don't understand it very well, but I tried to follow the example here:

    When I try it without using window.OpenerElementID = btnSelect.ClientID
    then the window does not open.

    When I try these commands
             Dim item As GridDataItem = CType(e.Item, GridDataItem)

                Dim btnSelect As Button = CType(item("Select").FindControl("Select"), Button)

    then btnselect is null

    Here is the code to open the window:

      Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand
            If e.CommandName = "Select" Then
                Dim PersonID As String = e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("PersonID").ToString
                'If permission_ID = 1 or 2 do NOT display link to scs
                Dim item As GridDataItem = CType(e.Item, GridDataItem)

                Dim btnSelect As Button = CType(item("Select").FindControl("Select"), Button)

            End If
        End Sub
        Private Sub ShowWindowPopUp(ByVal btnSelect As Button)
            'Private Sub ShowWindowPopUp()
            Dim window As New RadWindow()
            window.EnableEmbeddedSkins = False
            window.Title = "Add Comments"
            window.Skin = "Default"
            window.ShowContentDuringLoad = False
            window.VisibleStatusbar = False
            window.ReloadOnShow = True
            window.Behaviors = WindowBehaviors.Reload Or WindowBehaviors.Close Or WindowBehaviors.Move
            window.Modal = True
            window.Width = Unit.Parse("500px")
            window.Height = Unit.Parse("450px")
            window.OpenerElementID = btnSelect.ClientID
            window.VisibleOnPageLoad = True
            window.NavigateUrl = "DisplayPicture.aspx"
        End Sub

    Hi John,

    The RadWindow should be added either to the form's Controls collection or (recommended) to a standard placeholder control in that form.
    Another option is to use the client-side API of the controls and to open the window with JavaScript as shown here.

    All the best,
