BindingManagerBase.CurrentChanged BindingManagerBase.CurrentChanged BindingManagerBase.CurrentChanged BindingManagerBase.CurrentChanged Event

Definition

Occurs when the currently bound item changes.

public:
 event EventHandler ^ CurrentChanged;
public event EventHandler CurrentChanged;
member this.CurrentChanged : EventHandler 
Public Custom Event CurrentChanged As EventHandler 

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.
