Examples

The following example demonstrates how to handle the ItemValuePushed event. It assumes that you have a DataRepeater control named DataRepeater1 that has its VirtualMode property set to True, and that you have a data store for a data source named Employees.

private void dataRepeater1_ItemValuePushed(object sender, Microsoft.VisualBasic.PowerPacks.DataRepeaterItemValueEventArgs e)
{
    Employee emp = Employees[e.ItemIndex];
    switch (e.Control.Name)
    {
        case "txtFirstName":
            emp.firstName = e.Control.Text;
            break;
        case "txtLastName":
            emp.lastName = e.Control.Text;
            break;
        default:
            MessageBox.Show("Error during ItemValuePushed unexpected control: " + e.Control.Name);
            break;
    }
}

Private Sub DataRepeater1_ItemValuePushed(
    ByVal sender As Object, 
    ByVal e As Microsoft.VisualBasic.PowerPacks.DataRepeaterItemValueEventArgs
  ) Handles DataRepeater1.ItemValuePushed

    Dim emp As Employee = Employees.Item(e.ItemIndex)
    Select Case e.Control.Name
        Case "txtFirstName"
            emp.firstName = e.Control.Text
        Case "txtLastName"
            emp.lastName = e.Control.Text
        Case Else
            MsgBox("Error during ItemValuePushed unexpected control: " & 
                e.Control.Name)
    End Select
End Sub
