Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ListView.DrawSubItem event. This report helps you to learn when the event occurs and can assist you in debugging.

To run the example code, paste it into a project that contains an instance of type ListView named ListView1. Then ensure that the event handler is associated with the ListView.DrawSubItem event.

private void ListView1_DrawSubItem(Object sender, DrawListViewSubItemEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "DrawDefault", e.DrawDefault );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Bounds", e.Bounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Item", e.Item );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "SubItem", e.SubItem );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ItemIndex", e.ItemIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Header", e.Header );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ItemState", e.ItemState );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "DrawSubItem Event" );
}

Private Sub ListView1_DrawSubItem(sender as Object, e as DrawListViewSubItemEventArgs) _ 
     Handles ListView1.DrawSubItem

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "DrawDefault", e.DrawDefault)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Bounds", e.Bounds)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Item", e.Item)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "SubItem", e.SubItem)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ItemIndex", e.ItemIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Header", e.Header)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ItemState", e.ItemState)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"DrawSubItem Event")

End Sub

Remarks

Use this property when handling the ListView.DrawSubItem event for subitems that you do not want to customize. If you set this property to true, the subitem will be drawn normally using the current values of the ListViewItem.ListViewSubItem.BackColor, ListViewItem.ListViewSubItem.ForeColor, and ListViewItem.ListViewSubItem.Font properties

Note

The UseItemStyleForSubItems property of the parent ListViewItem must be set to false to prevent the ListViewItem.BackColor value of the parent item from overriding the subitem value.
