Public MustOverride ReadOnly Property Current As Object

Property Value

An Object that represents the current object.

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 Current object contains the value of the current item in the data source. To use the value of the current item, you must cast the item to the Type of the object contained by the DataSource. For example, a DataTable contains DataRowView objects. To determine the type of the current object, use the GetType and ToString methods.
