RadContextMenu Does not Close after Displaying Dialog Window
Environment
| Product Version | 2020.2.617 |
| Product | RadContextMenu for WPF |
Description
RadContextMenu stays open after selecting a menu item and/or opening a dialog window.
Solution
This behavior is observed because of the timing of executing a menu item's command or custom click logic and closing the menu along with the nature of the dialog windows. The custom click logic of the item is executed before the closing of the menu and if a dialog is opened at this point, it freezes the rest of the UI and the menu remains opened.
To resolve this you can use the application's Dispatcher to delay the opening of the dialog as shown in Example 1.
Example 1: Delaying the opening of a dialog window
private void RadContextMenu_ItemClick(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
Dispatcher.BeginInvoke(new Action(() =>
{
MessageBox.Show("Command Executed!");
}));
}
