DrawListViewItemEventArgs.ItemIndex 属性

定义

获取该 ListViewItem 在包含它的 ItemsListView 集合内的索引。

public:
 property int ItemIndex { int get(); };
public int ItemIndex { get; }
member this.ItemIndex : int
Public ReadOnly Property ItemIndex As Integer

属性值

ListViewItemItems 集合内的索引。

示例

下面的代码示例演示了此成员的用法。 在此示例中,事件处理程序报告事件的发生情况 ListView.DrawItem 。 此报告可帮助你了解事件发生的时间,并可以帮助你进行调试。

若要运行示例代码,请将其粘贴到包含名为 ListView1的类型的ListView实例的项目中。 然后,确保事件处理程序与 ListView.DrawItem 事件相关联。

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
