ControlBindingsCollection.Add Method (Binding)

Adds the specified Binding to the collection.

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

public void Add(
	Binding binding
)

Parameters

binding
Type: System.Windows.Forms.Binding

The Binding to add.

ExceptionCondition
ArgumentNullException

The binding is null.

ArgumentException

The control property is already data-bound.

ArgumentException

The Binding does not specify a valid column of the DataSource.

The DataSourceUpdateMode property of the Binding created by this overload of the Add method is set to the value of the DefaultDataSourceUpdateMode property.

The CollectionChanged event occurs when the change is complete.

The following code example creates a Binding instance, and uses the Add method to add the instance to the ControlBindingsCollection of a TextBox control.

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);
}
