Dragging the window stops after some time

[Patrick]

Hello,

If I click the title of the window and move it, it stops working, after a few movement (i.e. after two movements in 8), the window returns to its original position and no more moves.

This is with Office2016 theme, not checked with other ones.

Hello Patrick,

I have seen a similar drag issues when a XAML inspecting tool is attached to the process. For example, Snoop, WPFInspector or Visual Studio's built-in tool. Can you check this on your side? Also, can you share a bit more information about your setup? What is your RadWindow definition - can you share some code? Are there any customizations applied? How many monitors do you have and what is their DPI scale setting?

H Martin,

You're right: this only shows when running under VS, with the XAML tools enabled.

For your other questions:

1. This is not a RadWindow, but a RadSaveFileDialog.
2. No customizations, just the Office theme.
3. A single monitor with 100% display

Hello Patrick,

Thank you for the provided information. As for the RadWindow, please excuse me for this. It looks like I was caught by the word "window".

The dragging issue can be observed on different occasions and in various controls. I don't have much information about the origin of this, but it seems that the XAML inspectors are interfering with the drag/drop events. I guess at some point the inspector is catching the mouse which stops the currently running drag/drop action in the WPF application.

To avoid this, you can disable the XAML inspector (the Visual Studio XAML tools in your case) and enable it only when you need to inspect something.
