Question

I have a datagridview in my C# application and the user should only be able to click on full rows. So I set the SelectionMode to FullRowSelect.

But now I want to have an Event which is fired when the user double clicks on a row. I want to have the row number in a MessageBox.

I tried the following:

 this.roomDataGridView.CellContentDoubleClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.roomDataGridView_CellCont‌ ​entDoubleClick); 

 private void roomDataGridView_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
 {
      MessageBox.Show(e.RowIndex.ToString());
 }

Unforunately nothing happens. What am I doing wrong?

Don’t manually edit the .designer files in visual studio that usually leads to headaches. Instead either specify it in the properties section of your DataGridRow which should be contained within a DataGrid element. Or if you just want VS to do it for you find the double click event within the properties page->events (little lightning bolt icon) and double click the text area where you would enter a function name for that event.
