Hi All, I am using WinDockManager controls in App.while pin and unpining the tab controls inside pens are rendering very slow..please check below diffrence with images
Control renderation while pinning the Tab..
Actual controls after renderation complete.
Do you have complicated logic being done when you controls are resizing. It's possible there is nothing we can do. When you unpin a control, it just removes it from the Form and allows other controls to take up additional space. When they are taking up that space, they are laying themselves out again and repainting. It's possible this is causing the slowdown.
