Question

I have a DataGridView where one of the columns is a DataGridViewComboBoxColumn. When the grid is populated, that column looks different because of the drop-down arrow appearing on each cell in the column. I’d like to change this so that the drop-down arrow is hidden and only shows up when the row is actually highlighted or when the combobox cell is selected for editing. The behavior I wanted is like how the Properties window in Visual Studio handles its values.

Answer 1

In the DataGridViewComboBoxColumn, there is a property called DisplayStyle. Set it to Nothing to hide the DropDownButton

Further information about the DataGridViewComboBoxDisplayStyle enumeration is available at this MSDN link
