Hi,

Insert a datagridview in your form and name it "MyDataGridView".

To Add datagridviewcomboboxcolumns in your DataGridView, right click your datagridview in design window and select properties.

Then look for property "Columns". Then click the "..." button. Click Add button to add Columns...

Put the following code in your code window, to activate Combobox auto dropdown when focus ...

VB

Private Sub MyDataGridView_CellEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles MyDataGridView.CellEnter ''# Code to Dropdown DataGridViewComboBox in single click ''Header Cell clicked -> ignore it. If (e.RowIndex = -1) Then Return End If MyDataGridView.BeginEdit(True) If TypeOf MyDataGridView.EditingControl Is DataGridViewComboBoxEditingControl Then Dim control As DataGridViewComboBoxEditingControl = MyDataGridView.EditingControl If Not IsNothing(control) Then control.DroppedDown = True End If End If '#End of Code to Dropdown DataGridViewComboBox End Sub
