DataRepeater.ItemCloned Event

Occurs after the DataRepeaterItem and its controls are cloned from the ItemTemplate.

Namespace:  Microsoft.VisualBasic.PowerPacks
Assembly:  Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)

Syntax

'宣言
Public Event ItemCloned As DataRepeaterItemEventHandler

public event DataRepeaterItemEventHandler ItemCloned

public:
 event DataRepeaterItemEventHandler^ ItemCloned {
    void add (DataRepeaterItemEventHandler^ value);
    void remove (DataRepeaterItemEventHandler^ value);
}

member ItemCloned : IEvent<DataRepeaterItemEventHandler,
    DataRepeaterItemEventArgs>

JScript does not support events.

Remarks

Use this event to fix the display of any controls that are not cloned correctly by the default cloning process. For example, a ListBox control might not be populated with data during cloning; you can populate the list in the ItemCloned event handler.

注意

If you need complete control over the cloning process, use the ItemCloning event instead.

For more information about how to handle events, see Consuming Events.

Examples

The following example demonstrates how to repair the Items collection of a ListBox control in the ItemCloned event handler.

Private Sub DataRepeater1_ItemCloned(
    ByVal sender As Object, 
    ByVal e As Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs
  ) Handles DataRepeater1.ItemCloned

    Dim Source As ListBox = 
        CType(DataRepeater1.ItemTemplate.Controls.Item("ListBox1"), ListBox)
    Dim ListBox1 As ListBox = 
        CType(e.DataRepeaterItem.Controls.Item("ListBox1"), ListBox)
    For Each s As String In Source.Items
        ListBox1.Items.Add(s)
    Next
End Sub

private void dataRepeater1_ItemCloned(object sender, 
    Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs e)
{
    ListBox Source = (ListBox)dataRepeater1.ItemTemplate.Controls["listBox1"];
    ListBox listBox1 = (ListBox)e.DataRepeaterItem.Controls["listBox1"];
    foreach (string s in Source.Items)
    {
        listBox1.Items.Add(s);
    }
}
