Problem of WPF RadDocking on Winform ElementHost

[kj]

sample project

Hi,

Please refer to my sample project. Due to my project need to integrate Winform Main program and WPF usercontrol, I add an ElementHost on Form to place WPF usercontrol with RadDocking, but I found that RadDocking Component on Winform has problem.
When I drag a pane and move it, sometimes the pane will disappear. Please exact may sample project and execute WindowsApplication1.sln, then start debugging to produce the scenario, if the problem does not happen, please drag and dock the pane several more times, thanks.

PS: After compile sample project,  WindowsApplication1\WindowsApplication\bin\Debug have 2 .exe files
AddPanes.exe is pure WPF application, WindowsApplication.exe is my scenario application.

Hi kj,

Thank you for contacting us.

I tested the sample you sent us. Unfortunately, I could not reproduce the problem - the RadPane did not disappear.
However, pay attention on that if you place a WPF UserControl in windows form, the ToolWindow goes behind the windows form when the form gets the focus. That's because the window form stay above the WPF UserControl.

I hope this information helps. I will be glad to assist you further.

Regards,
