DataGridViewColumnCollection Class
Represents a collection of DataGridViewColumn objects in a DataGridView control.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
You can retrieve an instance of this class through the Columns property of the DataGridView control. The collection maintains a reference to the control through the DataGridView property.
The following code example illustrates the use of this type.
Private WithEvents dataGridView1 As New DataGridView() Private Sub AddColorColumn() Dim comboBoxColumn As New DataGridViewComboBoxColumn() comboBoxColumn.Items.AddRange( _ Color.Red, Color.Yellow, Color.Green, Color.Blue) comboBoxColumn.ValueType = GetType(Color) dataGridView1.Columns.Add(comboBoxColumn) End Sub Private Sub dataGridView1_EditingControlShowing(ByVal sender As Object, _ ByVal e As DataGridViewEditingControlShowingEventArgs) _ Handles dataGridView1.EditingControlShowing Dim combo As ComboBox = CType(e.Control, ComboBox) If (combo IsNot Nothing) Then ' Remove an existing event-handler, if present, to avoid ' adding multiple handlers when the editing control is reused. RemoveHandler combo.SelectedIndexChanged, _ New EventHandler(AddressOf ComboBox_SelectedIndexChanged) ' Add the event handler. AddHandler combo.SelectedIndexChanged, _ New EventHandler(AddressOf ComboBox_SelectedIndexChanged) End If End Sub Private Sub ComboBox_SelectedIndexChanged( _ ByVal sender As Object, ByVal e As EventArgs) Dim comboBox1 As ComboBox = CType(sender, ComboBox) comboBox1.BackColor = _ CType(CType(sender, ComboBox).SelectedItem, Color) End Sub
