RadContentMenu Exception

[xu qing]

Hi,

    I use the RadContentMenu Control to provide contentmenu in my application.I write my code follow the demo:

    http://demos.telerik.com/silverlight/#GridView/RowContextMenu

    

    When I run my code and click right mouse on GridView,the contentmenu is not the menu I defind,it's the default right menu of Silverlight.The content of menu is:"Silverlight(S)".

    

    Then I use the MouseRightButtonDown Event of GridView to display RadContentMenu by Code.Follow is my event hand code:

    

    private void GList_MouseRightButtonDown(object sender, MouseButtonEventArgs e)

        {

          //open radcontentmenu

            this.ConentMenu.IsOpen = true;

            //disable default contentmenu

            e.Handled = true;

        }

    

    Then I run my code and right mouse on GridView,the RadContentMenu displayed.After that,I write the Opened Event of RadContentMenu,Follow is my code:

    

    private void ConentMenu_Opened(object sender, RoutedEventArgs e)

        {

         RadContextMenu menu = (RadContextMenu) sender;

        

         //Get the selectRow

            GridViewRow selectRow = menu.GetClickedElement<GridViewRow>();

            if (selectRow != null)

            {

              //Set the selectRow as local select row

                selectRow.IsSelected = true;

            }

        }

    

    I run my code again,An Exception happend in the RadContentMenu Opend Event hand Code.The Expend is:Value is not within the expected range.

    

    Follow is the detail of this Exception:

    

    System.ArgumentException was unhandled by user code

   Message=Value is not within the expected range.

Hello,

I experience the same "Value is not within the expected range" exception in the ContextMenu_Opened method. Specifically, it happens when I right-click immediately after left-clicking on a gridview row. Did you already find a solution for this problem? 

Here is my code. The exception occurs at the line "GridViewRow row = menu.GetClickedElement<GridViewRow>();"

private void ContextMenu_Opened(object sender, RoutedEventArgs e)
        {
            RadContextMenu menu = (RadContextMenu)sender;
            GridViewRow row = menu.GetClickedElement<GridViewRow>();

            if (row != null)
            {
                /*
                 * If the row clicked upon was not selected, all other selected items
                 * will be reset, and the context menu aplies only to this single row.
                 * If the row wás selected before the context menu is opened,
                 * the context menu will aply to all the selected items.
                 */
                if (!row.IsSelected)
                {
                    functionList.SelectedItems.Clear();
                }
                row.IsSelected = row.IsCurrent = true;
                GridViewCell cell = menu.GetClickedElement<GridViewCell>();
                if (cell != null)
                {
                    cell.IsCurrent = true;
                }
            }
            else
            {
                menu.IsOpen = false;
            }
        }

Thanks

Hi,
I got this exception because I use a radwindow control in the login xaml file "login.xaml",and when I goto main.xaml,the radwindow didn't closed.when I close this window before goto main.xaml,the exception don't happend.
By the way,If you select the radsilverlight project when you create your project.the mouserightbutton event will be handled automatic.
