I have a tabcontrol . I put an image control on one tab and a listview control on the other. This tabcontrol is wrapped in a dockpanel. When I mazimize the window, the one tab control also mazimizes, OK, but the tab with the listview doesn't show mazimized listview, the listview stays the same size. Anyone can help me make it docked to the tab so that when mazimizing the main windows also mazimizes the listview ?

Thank youuuuu
