Context menu in the grid header

[ron klod]

Hi,

Ihave a class that inherits from RadGridView,
for each instacne of this grid we always add a button in the header of the first column, when clicking on this button it shold open a context menu, I have locked at your example onhow to do it but it does not work for me, here is my code:

this is the code that I am adding to the grid header, it is being added in OnApplyTemplate:
GridViewColumn column = this.Columns[0];

           string headerText = column.Header.ToString();

           StackPanel headerPanel = new StackPanel();

           headerPanel.Orientation = Orientation.Horizontal;

           Button b = new Button();

           b.Content = "Menu";

           b.Click += new RoutedEventHandler(b_Click);

           headerPanel.Children.Add(b);

           TextBlock t = new TextBlock();

           t.Text = headerText;

           headerPanel.Children.Add(t);

           column.Header = headerPanel;

this is the event hanlder of the added button

void b_Click(object sender, RoutedEventArgs e)

       {

           RadContextMenu contextMenu = new RadContextMenu();

           contextMenu.ItemClick += new Telerik.Windows.RadRoutedEventHandler(contextMenu_ItemClick);

           // set menu Theme

           StyleManager.SetTheme(contextMenu, StyleManager.GetTheme(this));

           RadMenuItem item = new RadMenuItem() { Header = "Export CSV" };

           //item.Click += new Telerik.Windows.RadRoutedEventHandler(item_Click);

           contextMenu.Items.Add(item);

           RadMenuItem item1 = new RadMenuItem() { Header = "Print" };

           //item1.Click += new Telerik.Windows.RadRoutedEventHandler(item1_Click);

           contextMenu.Items.Add(item1);

           //contextMenu.AddHandler(RadMenuItem.ClickEvent, new RoutedEventHandler(OnMenuItemClick));\\

           RadContextMenu.SetContextMenu((sender as Button), contextMenu);

              

           // attach menu

          // RadContextMenu.SetContextMenu(cell, contextMenu);

     

       }

Hi ,

 If you want this button to have context menu you should add the menu (and associate this menu with the button) when the button is created - not on click.
