      • I would like to change the Text Size of the WebBrowser control (.NET 2.0). The control doesn't provide the function itself. I have found information that it has to be done like this: ((UnsafeNativeMethods.IWebBrowser2)webBrowser.ActiveXInstance).ExecWB(19, 2, 0); The problem is that UnsafeNativeMethods is a static class of the Windows.Forms.dll assembly. Thus I am not able to cast the object

What I want to do is enable the user to not only edit the data in the grid (which is easy), but also change the order of the lines. The best solution will be to add 2 Up and Down arrow on the form to allow the user to do it. That will be the most friendly solution.
