Horizontal Scrollbar is not visible on DataGridView

When I encountered this annoying problem, it was due to the AutoSizeColumnsMode property of the DGV that was set to Fill

I fixed it by changing that property to AllCells, but any other value will work. It works even if the DGV is docked and I have multiple docked panels, and the first column is Frozen.

Well Guys, its sorted out.

I am answering my own question; it may help someone in future.

one of the columns has Frozen property set as True. which should be false for all columns. Now ScrollBar is working absolutely fine for me.

Cheers

I know this has already been resolved, but I've come across another reason why this could happen, so thought I'd add it as an answer in case someone else has the same problem.

If your form has a DataGridView that is docked to fill the form, and the form also has a status bar, then depending on the order they're created, the status bar can hide the DataGridView's scrollbar. To fix this, right click on the DataGridView, and select "Bring to Front".
