Question: I have a setup in my code where there is a datagridview. For each row I have a combo box cell that I have a separate combo box cell since I want a different selection of items for each cell. 

**Problem** : The cell only drops down when the arrow is double clicked. How can I change the cell formatting, or possibly a cell click event, so that the cell response to just one click?

Here's my cell creation code. Frankly, I didn't start any other code since I didn't know what event to touch or call. Is there a property I can edit? 

**Code:**

```
           'add items to combobox list 
            Dim comboCell As New DataGridViewComboBoxCell 
            comboCell.FlatStyle = FlatStyle.Flat
            Dim resolutionList As New List(Of cmbStruct)

            Dim currentResIndex As Integer = 0

            'create list of resolutions
            For j As Integer = 0 To resolutions.Length - 1

                Dim resClass As New cmbStruct
                resClass.Name = resolutions(j)
                resClass.ID = resolutions(j)
                resolutionList.Add(resClass)
                comboCell.Items.Add(resolutions(j))

              Next

            'set combocell values
            comboCell.DisplayMember = "Name"
            comboCell.ValueMember = "ID"

           'set the default value to the current resolution index 

            Try
                comboCell.Value = resolutions(currentResIndex) 
            Catch ex As Exception

            End Try

            comboCell.ValueType = GetType(cmbStruct)
            comboCell.DataSource = resolutionList
            editCameraTable("Resolution", i) = comboCell

        Next

```

Answer: 
Change the EditMode property:

```
DataGridView1.EditMode = DataGridViewEditMode.EditOnEnter

```
There seems to be a nearly identical question and a very good answer. It involves using the click\_event. Here is the link:
[How to manually drop down a DataGridViewComboBoxColumn?](https://stackoverflow.com/questions/241100/how-to-manually-drop-down-a-datagridviewcomboboxcolumn)

**In the link:**

```
Private Sub cell_Click(ByVal sender As System.Object, ByVal e As DataGridViewCellEventArgs) Handles      DataGridView1.CellClick
    DataGridView1.BeginEdit(True)
    If DataGridView1.Rows(e.RowIndex).Cells(ddl.Name).Selected = True Then
        DirectCast(DataGridView1.EditingControl, DataGridViewComboBoxEditingControl).DroppedDown = True
    End If
End Sub

```
