问题 I have a bunch of ElementHosts that I'm loading onto my form. When this happens, the element hosts all appear with a black background.

问题 I use a WPF UserControl in my personal Libs. The Libs are included in my WPF and WindowsForms programs. Now my UserControl has to show a new (WPF) Window. At the new Window I want to set the Owner. I do it like this: dialog.Owner = Application.Current.MainWindow; This works fine, if i use the UserControl in a WPF program.

I have a problem with a WPF control that I'm trying to host in an ElementHost in a WinForms app. The control is a lookless custom control that I originally developed in a separate test project, which was a WPF app. In there it obviously works fine, but in my WinForms app all I get is a blank grey box where the ElementHost is displayed. Here's my C# code for creating, populating, and adding the ElementHost to the parent Control: // This is my WPF control m_TabHostPanel = new TabHostPanel(); m_ElementHost = new ElementHost { Child = m_TabHostPanel, Dock = DockStyle.Top, Height = 34 }; this
