Exemples

L’exemple de code suivant obtient la BindingMemberInfo de chaque Binding sur un formulaire, puis imprime les valeurs de propriété BindingPath, BindingFieldet BindingMember de BindingMemberInfo.The following code example gets the BindingMemberInfo of each Binding on a form, and prints the BindingPath, BindingField, and BindingMember property values of BindingMemberInfo.

private:
   void PrintBindingMemberInfo()
   {
      Console::WriteLine( "\n BindingMemberInfo" );
      for each ( Control^ thisControl in this->Controls )
      {
         for each ( Binding^ thisBinding in thisControl->DataBindings )
         {
            BindingMemberInfo bInfo = thisBinding->BindingMemberInfo;
            Console::WriteLine( "\t BindingPath: {0}", bInfo.BindingPath );
            Console::WriteLine( "\t BindingField: {0}", bInfo.BindingField );
            Console::WriteLine( "\t BindingMember: {0}", bInfo.BindingMember );
            Console::WriteLine();
         }
      }
   }
private void PrintBindingMemberInfo()
{
   Console.WriteLine("\n BindingMemberInfo");
   foreach(Control thisControl in this.Controls)
   {
      foreach(Binding thisBinding in thisControl.DataBindings)
      {
         BindingMemberInfo bInfo = thisBinding.BindingMemberInfo;
         Console.WriteLine("\t BindingPath: " + bInfo.BindingPath);
         Console.WriteLine("\t BindingField: " + bInfo.BindingField);
         Console.WriteLine("\t BindingMember: " + 
         bInfo.BindingMember);
         Console.WriteLine();
      }   
   }
}
Private Sub PrintBindingMemberInfo()
   Console.WriteLine(ControlChars.Cr + " BindingMemberInfo")
   Dim thisControl As Control
   Dim thisBinding As Binding
   For Each thisControl In  Me.Controls    
      For Each thisBinding In  thisControl.DataBindings
         Dim bInfo As BindingMemberInfo =  _
         thisBinding.BindingMemberInfo
         Console.WriteLine(ControlChars.Tab + _
         " BindingPath: "  + bInfo.BindingPath)
         Console.WriteLine(ControlChars.Tab + _
         " BindingField: " + bInfo.BindingField)
         Console.WriteLine(ControlChars.Tab + _
         " BindingMember: "  + bInfo.BindingMember)
         Console.WriteLine()
      Next thisBinding
   Next thisControl
End Sub

Remarques

Le BindingPath est la combinaison séparée par des virgules des noms de propriétés qui précède le BindingField dans le chemin de navigation retourné par la propriété BindingMember.The BindingPath is the period delimited combination of property names that comes before the BindingField in the navigational path returned by the BindingMember property. Par exemple, lors de la création d’un Binding qui a un paramètre dataMember « Customers. custToOrders. OrderDate », BindingPath retourne « Customers. custToOrders ».For example, when a new Binding is created that has a dataMember parameter of "Customers.custToOrders.OrderDate", BindingPath will return "Customers.custToOrders".
