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)

public class DataGridViewColumnCollection : BaseCollection, IList, ICollection, IEnumerable
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 DataGridView dataGridView1 = new DataGridView();

private void AddColorColumn()
{
    DataGridViewComboBoxColumn comboBoxColumn =
        new DataGridViewComboBoxColumn();
    comboBoxColumn.Items.AddRange(
        Color.Red, Color.Yellow, Color.Green, Color.Blue);
    comboBoxColumn.ValueType = typeof(Color);
    dataGridView1.Columns.Add(comboBoxColumn);
    dataGridView1.EditingControlShowing +=
        new DataGridViewEditingControlShowingEventHandler(
        dataGridView1_EditingControlShowing);
}

private void dataGridView1_EditingControlShowing(object sender,
    DataGridViewEditingControlShowingEventArgs e)
{
    ((ComboBox)e.Control).SelectedIndexChanged +=
        new EventHandler(ComboBox_SelectedIndexChanged);
}

private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
    ((ComboBox)sender).BackColor = (Color)((ComboBox)sender).SelectedItem;
}
