public:
property bool DrawDefault { bool get(); void set(bool value); };public bool DrawDefault { get; set; }member this.DrawDefault : bool with get, setPublic Property DrawDefault As BooleanProperty Value
true if the system draws the item; false if the event handler draws the item. The default value is false.
Examples
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ListView.DrawItem 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.DrawItem event.
private void ListView1_DrawItem(Object sender, DrawListViewItemEventArgs 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}", "Item", e.Item );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Bounds", e.Bounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ItemIndex", e.ItemIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "State", e.State );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "DrawItem Event" );
}
Private Sub ListView1_DrawItem(sender as Object, e as DrawListViewItemEventArgs) _
Handles ListView1.DrawItem
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}", "Item", e.Item)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "Bounds", e.Bounds)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "ItemIndex", e.ItemIndex)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "State", e.State)
messageBoxVB.AppendLine()
MessageBox.Show(messageBoxVB.ToString(),"DrawItem Event")
End Sub
Remarks
Set this property to true when the item does not require custom drawing. This is useful when you need to customize only certain items within the control, such as selected items.
