Examples
The following code example prints the value of the Current object in a BindingManagerBase in the CurrentChanged event. The example assumes the data source is a DataTable containing a DataColumn named CustName
.
void Current_Changed( Object^ sender, EventArgs^ /*e*/ )
{
BindingManagerBase^ bm = dynamic_cast<BindingManagerBase^>(sender);
/* Check the type of the Current object. If it is not a
DataRowView, exit the method. */
if ( bm->Current->GetType() != DataRowView::typeid )
return;
// Otherwise, print the value of the column named "CustName".
DataRowView^ drv = dynamic_cast<DataRowView^>(bm->Current);
Console::Write( "CurrentChanged): " );
Console::Write( drv[ "CustName" ] );
Console::WriteLine();
}
private void Current_Changed(object sender, EventArgs e)
{
BindingManagerBase bm = (BindingManagerBase) sender;
/* Check the type of the Current object. If it is not a
DataRowView, exit the method. */
if(bm.Current.GetType() != typeof(DataRowView)) return;
// Otherwise, print the value of the column named "CustName".
DataRowView drv = (DataRowView) bm.Current;
Console.Write("CurrentChanged): ");
Console.Write(drv["CustName"]);
Console.WriteLine();
}
Private Sub Current_Changed(sender As Object, e As EventArgs)
Dim bm As BindingManagerBase = CType(sender, BindingManagerBase)
' Check the type of the Current object. If it is not a
' DataRowView, exit the method.
If bm.Current.GetType() IsNot GetType(DataRowView) Then
Return
End If
' Otherwise, print the value of the column named "CustName".
Dim drv As DataRowView = CType(bm.Current, DataRowView)
Console.Write("CurrentChanged): ")
Console.Write(drv("CustName"))
Console.WriteLine()
End Sub
Remarks
The CurrentChanged event is raised whenever the Current property changes or the CurrentItemChanged event occurs.
