I'm not 100% sure how I should word this question but I'll try my best.
I have a PointCtrlForm that has a DataGridView inside a TableLayoutPanel. The DataGridView is docked to the table as Fill. PointCtrlForm is docked to another window set as MDIParent with the dockstyle property set as Fill.
Resizing the main window properly resizes the PointCtrlForm, which then is supposed to resize the DataGridView as well. Well, at least "half" of the resizing works properly. Enlarging the main window also enlarges the datagridview, which is what I expected but if I shrink the main window to a certain point, the DataGridView stops shrinking and hides the columns without showing a scrollbar.
I've checked that all columns do not have Frozen property enabled, checked that both the datagridview and the child window is properly docked, and checked the scrollbars property is set to both.
Edit: AutoSizeColumnsMode is also fill.
I'll post the content of the Designer.cs here. I'd appreciate any guidance.
