C# WinForm DataGridView question

[Jason Huang]

Hi,

In my C# WinForm application, saying a DataGridView has 3 columns.
What I would like to do is to let the Column3' value equal to Column1 value
X Column2 value.
How do I do that?
Thanks for help.

I have not used it, but it seems that Virtual Mode with CellValueNeeded
event does the trick. The event occurs when the cell's value is needed
(to be shown), so you can calculate column3 from column1 times column2.

I think what you need to look into is the CellValueChanged event.
