I'm using a RadGridView with xaml and vb. One of the columns in the grid is a textbox. This same grid is used for both creating data and for viewing it later. The user can easily enter text in the textbox and the vertical scrollbar works fine. If the user is later just viewing this gridview, the textbox is readonly. The textbox has a vertical scrollbar, but the scrollbar doesn't work. Is this expected behavior with the textbox is readonly?
