Property Value

Type: System::Object^

An Object that represents the current object.

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.

System_CAPS_noteNote

When the DataSource is a DataSet, DataViewManager, or DataTable, you are actually binding to a DataView. Consequently, each Current object is a DataRowView object.

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();
}
