Example for deriving from datagridviewcell
I designed a user control that can be described as an enhanced combobox. It has more than just a dropdown button right besides the text field and offers much more functionalty. Because deriving from a combobox isn't very flexible it's derived from a user control and contains a textbox and some buttons on the right.
It looks like this:
[ Textbox ][But1][But2][But3]
Now I want to integrate this control in a datagrid. I already found out how to use it as the editing control for a datagridviewcell. But because the functionalty that is offered by the different buttons of the control has to be also accessible in non-editmode, I need to create my own datagridviewcell.
Can I inherit from a datagridviewtextboxcell and add my buttons on the right side somehow?
Otherwise I would like to see an example how to create your own datagridviewcell.
Thank you!

You can override the paint method of DataGridViewTextBoxCell to display your buttons. You will need to handle clicks yourself if clicks are meant for anything other than entering edit mode.
I am working on a sample in which I derive from DataGridViewCell. Let me know if you come up with anything in the meantime.
Could you please give me a starting point what I've to do to get a button by overriding the paint method?
Do I have to manually draw a button, draw it's image, etc. ?
Or can I create a new instance from a button and place it in the textbox?
What is the best way to handle the click?
Thanks a lot!

Hi David,
Did you find the way to derive from datagridviewcell? Could you send me some code to show how to do? Actually I'm trying to do exactly the same as you: I've created my own combo box (which displays a resizable TreeView), and I would like to use it in my datagridview.Many thanks in advance.
