Drag Provider very slow?

[Administrator]

Hello,

I am using the DockingManager with the default DragProvider. In runtime this is very slow. When I drag a window over other windows, the frame of the dragged window will still be visible for some time on the other windows. If I use the Standard DragProvider everything is lightning fast. The problem also occurs with the Whidbey provider.

Is there a fix for this?

Hi Kay, Sorry for the inconvenience caused.I was not able to reproduce the issue(slow dragprovider). There are some problems in painting when we drag controls.This is a known issue and we are currently working on it.The reason for this painting issue is the existence of any background process which paints any other controls very frequently I have attached a sample.Please modify that to bring the issue(slow dragprovider) and send to me.It will be great help in resolving this issue Thanks for using Syncfusion products. Regards, Joy
