使用例

[Visual Basic, C#, C++] Binding インスタンスを作成し、 Add メソッドを使用して、このインスタンスを TextBox コントロールの ControlBindingsCollection に追加する例を次に示します。

 
Protected Sub BindControls()
    ' Create a new Binding using the DataSet and a 
    ' navigation path(TableName.RelationName.ColumnName).
    ' Add event delegates for the Parse and Format events to 
    ' the Binding object, and add the object to the third 
    ' TextBox control's BindingsCollection. The delegates 
    ' must be added before adding the Binding to the 
    ' collection; otherwise, no formatting occurs until 
    ' the Current object of the BindingManagerBase for 
    ' the data source changes. 
    Dim b As New Binding("Text", ds, "customers.custToOrders.OrderAmount")
    AddHandler b.Parse, AddressOf CurrencyStringToDecimal
    AddHandler b.Format, AddressOf DecimalToCurrencyString
    textBox1.DataBindings.Add(b)
End Sub    

[C#] 
protected void BindControls()
{
   /* Create a new Binding using the DataSet and a 
   navigation path(TableName.RelationName.ColumnName).
   Add event delegates for the Parse and Format events to 
   the Binding object, and add the object to the third 
   TextBox control's BindingsCollection. The delegates 
   must be added before adding the Binding to the 
   collection; otherwise, no formatting occurs until 
   the Current object of the BindingManagerBase for 
   the data source changes. */
   Binding b = new Binding
   ("Text", ds, "customers.custToOrders.OrderAmount");
   b.Parse+=new ConvertEventHandler(CurrencyStringToDecimal);
   b.Format+=new ConvertEventHandler(DecimalToCurrencyString);
   textBox1.DataBindings.Add(b);
}

[C++] 
protected:
void BindControls()
{
   /* Create a new Binding using the DataSet and a 
   navigation path(TableName.RelationName.ColumnName).
   Add event delegates for the Parse and Format events to 
   the Binding object, and add the object to the third 
   TextBox control's BindingsCollection. The delegates 
   must be added before adding the Binding to the 
   collection; otherwise, no formatting occurs until 
   the Current object of the BindingManagerBase for 
   the data source changes. */
   Binding* b = new Binding(S"Text", ds, S"customers.custToOrders.OrderAmount");
   b->Parse+=new ConvertEventHandler(this, &Form1::CurrencyStringToDecimal);
   b->Format+=new ConvertEventHandler(this, &Form1::DecimalToCurrencyString);
   textBox1->DataBindings->Add(b);
}
