VB.net DataGridView1_CellValueChanged  - get this to run when ComboBox selection is made

Murray Brown

I have a DataGridView where I add several ComboBox columns programatically.

I need to run code when a ComboBox selection is made but the event DataGridView1_CellValueChanged only runs when I click another cell.

How can I run this code without having to select another cell? Is there another event that
I should rather use?

Why not you add a combo box at form level with events, then you can check the combo box index changed event.

I can't do that in this case because the columns names have to be the same as changing data
Perhaps DataGridView1.CommitEdit is the way. What code would I use?
It will work here, but you have to handle different situations yourself. Try create a new form and put this codes in, create a datagridview named datagridview1

    Private WithEvents colX As New DataGridViewComboBoxColumn

    Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        colX.HeaderText = "Display 1"
        colX.Name = "MyColumn1"
        colX.DisplayIndex = 0 'set as the first column in the grid
    End Sub

    Private Sub DataGridView1_EditingControlShowing(ByVal sender As System.Object, ByVal e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
        Dim editingComboBox As ComboBox = e.Control
        AddHandler editingComboBox.SelectedIndexChanged, AddressOf Me.editingComboBox_SelectedIndexChanged
    End Sub

    Private Sub editingComboBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
        'Handle your codes here to identity correct method and do what you required
        MsgBox("You see me when you changed the value of a combobox")
    End Sub
