Apparent splitter control bug

Question

Has anyone noticed that when a splitter control is used to resize 2 horizontally docked controls, 1 on the left and 1 on the right, it works fine. But if a splitter control is used to resize 2 vertically docked controls, 1 docked to the top, 1 to the bottom, there is an error - resizing the docked controls makes the splitter gain in height and/or the bottom docked control move up in the form. Bad stuff. Is this a known bug?

My mistake - it appears to work IF and only if the top control associated with the splitter is docked using the full docked property. Before I was trying with the bottom control using the full docked property. So in summary it works if: topControl.Docked = DockStyles.Full; bottomControl.Docked = DockStyles.Bottom; I'm gonna submit some code for this one ;)

I got similar error in DataGrid docked in new form after reloading DataSource in DataGrid when new record count is bigger then older and resising form(!). Workaround: myDataGrid.Dock=DockStyle.Top; myForm.Show(); myDataGrid.Dock=DockStyle.Fill; May be any trick like this will be useful.

I haven't looked at this so I don't know if it's a bug or not but if you are pretty sure it is you might want to add it to this site which has a list of some .NET bugs. Hopefully the guys at MS will check it out.
