I'm using 2009 Q3 Winforms. In order to create a multi-select dropdown combobox, I used a few other forum posts' responses as a guide. I created a GridMenuItem class that inherited from RadMenuItemBase and implemented INotifyPropertyChanged. That GridMenuItem contains a RadGridView and adds that GridView as a RadHostItem to its children.
Anyway, what happens is that the dropdown grid will resize itself each time you drop it down. It appears to be decreasing the height while increasing the width, by a small amount (I think around 6 both ways). Eventually you get to an ever-increasing line. I cannot seem to figure out what is wrong.
Below is the code to show what is happening.
Thoughts?
