I created a custom DataGridViewCell to show a specific UserControl when the user starts

  • 0

I created a custom DataGridViewCell to show a specific UserControl when the user starts editing the cell. Basically the control contains a TextBox with a suggestion list easily handled by the code.
I got my code to resize the list correctly, and have it contain exactly what I want and where I want it. The problem I have now is that the control is not being drawn correctly on the screen, and the ListBox is probably beind drawn “inside” the row, and since it is much higher than the row, does not get shown on screen.

How can I make the control draw on top of the DataGridView?

    You’ll probably need to put the ListBox in a separate popup form. Good luck.

    Alternatively, you can put the ListBox in the GridView’s parent form, then call BringToTop to make sure it’s on top of the grid view.
