DataGridView item double click

Question

I have a DataGridView in a Windows Form. I want to handle double click events on each cell to display a detail form related to that record. Unfortunately, the double click event is executed when you double click on column headers. What should I do?

Answer 1

You should check the RowIndex and ColumnIndex property of the event arguments. If one of them is negative, it means that either a row header or a column header is clicked, you should ignore that event.

Answer 2

What event are you handling? Ideally you should handle the CellDoubleClick or the CellMouseDoubleClick events and opening your details form in that handler. The latter event will catch a Double click using any of the mouse buttons (the button can be queried using the MouseEventArgs.Button property.
