i used a GroupBox with a scrollviewer inside it ..and inside scrollviewer i put a grid and begin to put my controls (3 textblocks and 6 textboxes)
-after making my scrollviewer to scroll my content (the remaining 3 textboxes) i faced a trouble of grid inside scrollviewer appear behind things like the next pic
