DataGridViewColumnCollection Class

Note: This class is new in the .NET Framework version 2.0.

Represents a collection of DataGridViewColumn objects in a DataGridView control.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

'Declaration
Public Class DataGridViewColumnCollection
	Inherits BaseCollection
	Implements IList, ICollection, IEnumerable
'Usage
Dim instance As DataGridViewColumnCollection

public class DataGridViewColumnCollection extends BaseCollection implements IList, ICollection, 
	IEnumerable
public class DataGridViewColumnCollection extends BaseCollection implements IList, ICollection, 
	IEnumerable

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 comboBox1 As ComboBox = CType(e.Control, ComboBox)
    AddHandler comboBox1.SelectedIndexChanged, _
        New EventHandler(AddressOf ComboBox_SelectedIndexChanged)

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
