I have a requirement to hide the minimize and maximize buttons on header but i want to use the resize the window with cursor at bottom right corner. can you please tell me how i can achieve this ?
You can easily remove minimize and maximize buttons. What you need to do is to modify the ControlTemplate of the RadWindow control and remove the buttons from the original one. These buttons have their Name properties set to PART_MinimizeButton and PART_MaximizeButton. Please, review the attached project.
