Cannot type on textbox on DockingManager is in Float mode

On my test project WIndows Form, I'm opening a WPF popup, there is DockManager with a textbox in it, another textbox outside, but the textbox inside the DockManager is not working, I cannot type anything when is in Float mode. I don't have issue with Dock mode.

Hi Gregory,


Your reported issue is present in Framework. It is already discussed in the MSDN forum. Please use "System.Windows.Threading.Dispatcher.Run()" method when loading UserControl from WinForms. Please refer to the modified sample for your reference. Please refer to the solution from the following forum discussion.

Code snippets:

public Form1()
{
InitializeComponent();
var us = new UserControl2();
ElementHost.EnableModelessKeyboardInterop(us);
us.Show();
ystem.Windows.Threading.Dispatcher.Run();

}
