In CellContentDoubleClick event fires only when double clicking on cell’s content. I used this and works: private void dgvUserList_CellDoubleClick(object sender, DataGridViewCellEventArgs e) { MessageBox.Show(e.RowIndex.ToString()); }
DataGridView.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells See http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.autosizerowsmode.aspx
I was having quite a bit of trouble with this myself. I have a user control with a DataGridView that is populated on application/form load.

To use it as a data source in a grid view, you just have to follow it with ToArray(). dataGridView1.DataSource … Read more
The problem with the line: select new { c.UserName, c.Password, c.Description } Is that it is creating an anonymous type, and anonymous types are immutable – that is read only. This is why your changes do not get reflected in either the new type or in the original EF object. Now, as for ways of … Read more

For anyone else: The problem was that I was trying to assign the DataGridViewComboBoxCell.Value to an object, expecting that because the Cell was bound to a data source that it would automatically find the object in the source and update.
