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 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
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;
}
}
