Drag Provider very slow?

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? Kay Wilke

Hi Kay, Could you please let me know, the version of Essential studio and .net framework you are using now? Regards, Joy

Hi, the version is 4.1.0.62 Thanks, Kay

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
