I had created a dock and it have three documentWindows
I want to set a fixed size for documentWindow1 so that its size did not change even if i had changed the size of my main window.
Is it possible to set fixed height and width separately ?
You cannot control both dimensions (width and high) together of RadDocumentWindow independently from the size of RadDock. By design RadDock arranges windows according their DockState and ignores their set size if they are not in split panel with windows from same type. So RadDock manages the size of the docked RadDocumentWindow and there is not suitable way to change that behavior.
Attached demo demonstrates several possible scenarios with partial success because you can control only one dimension - width or high
