Hi , We have an issue with Window with Transparency= true to resize them at run-time We want to create non-rectangular Window with no border and Full transparency; so, we have create a Window with AllowTransparency=true and we have added a Grid with some Controls inside; this works well and the window can be dragged on the desktop; The issue is coming when I try to resize my window at run-time; as I don't have any border, I have added a Thumb control and I use the DragDelta method to do the job; the real issue is when I resize my Grid in a bigger size which make parts of it clipped outside the window; so, I have tried to resize dynamically the window in same time of the grid in the DragDelta method, but it seems that's a bug doesn't allow this ... Steps to reproduce: we create a Windows with AllowTransparency=true and inside we add a grid, then inside some controls; at runtime, we use a Thump control to resize the grid and offcourse, we have to resize the Windows otherwise some parts of the displayed grid are rendered outside the window; we played with a lot of windows property but we can't make it work.... later, we have discovered that if we set the window border visible removing the AllowTransparency, then relaunch the sample: - we click on the red square to resize, the windows doesn't size - Take the mouse and size manually once the windows, then click again the red square, now the windows resize ... I know I could set the Window with a size of 2000x2000 to be sure but I would avoid having huge window for nothing... Thxs for any help Regards -Vince |
