Greetings I have a combobox which filters all the items in the by clearing the panel controls and repopulating it according to the filter, but for whatever reason it loads them improperly and after a couple of filter changes only shows some and not all. It reads it from a litst passing it to another which has all the filtered ones yet it still cant do it.

In a C# WFA I’ve been coding my own control that inherits from the System.Windows.Forms.Panel control. What I wanted to do is when the mouse is dragged within this panel (so basically mouse gets down while inside the panel and then mouse moves), I wanted to restrict the movement of the cursor to be only within this panel. So when the cursor hits the bounds of the panel, the movement should be restricted as to not get any further beyond the bounds.
