CurrencyManager::Position Property

Gets or sets the position you are at within the list.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
virtual property int Position {
	int get () override;
	void set (int value) override;
}

Property Value

Type: System::Int32
A number between 0 and Count minus 1.

An important property of the CurrencyManager class is the Position property. In a list of items, you can view only one item out of the entire list. To determine which item is viewed, set the Position to a number between 0 (the beginning of the list) and Count minus 1 (the end of the list).

Therefore, the Position determines the currency, or place in the list, of all controls bound to the same CurrencyManager. For example, imagine a list consisting of two columns called "FirstName" and "LastName". Two TextBox controls are bound to the same list; the first control is bound to the first column, and the second control is bound to the second column. When the Position of the common CurrencyManager is set to the third position, both controls display the appropriate values for that position in the list. In other words, if the item at position three consists of the first name "John" and the last name "Smith", the bound controls will display "John" and "Smith".

The following code examples use the Position property to allow navigation through a list.

private:
   void MoveNext( CurrencyManager^ myCurrencyManager )
   {
      if ( myCurrencyManager->Count == 0 )
      {
         Console::WriteLine( "No records to move to." );
         return;
      }

      if ( myCurrencyManager->Position == myCurrencyManager->Count - 1 )
      {
         Console::WriteLine( "You're at end of the records" );
      }
      else
      {
         myCurrencyManager->Position += 1;
      }
   }

   void MoveFirst( CurrencyManager^ myCurrencyManager )
   {
      if ( myCurrencyManager->Count == 0 )
      {
         Console::WriteLine( "No records to move to." );
         return;
      }

      myCurrencyManager->Position = 0;
   }

   void MovePrevious( CurrencyManager^ myCurrencyManager )
   {
      if ( myCurrencyManager->Count == 0 )
      {
         Console::WriteLine( "No records to move to." );
         return;
      }

      if ( myCurrencyManager->Position == 0 )
      {
         Console::WriteLine( "You're at the beginning of the records." );
      }
      else
      {
         myCurrencyManager->Position -= 1;
      }
   }

   void MoveLast( CurrencyManager^ myCurrencyManager )
   {
      if ( myCurrencyManager->Count == 0 )
      {
         Console::WriteLine( "No records to move to." );
         return;
      }
      myCurrencyManager->Position = myCurrencyManager->Count - 1;
   }
