Remarks

A collection of ExpressionBinding objects is returned by the XRControl.ExpressionBindings property.

When the UserDesignerOptions.DataBindingMode property is set to DataBindingMode.Expressions or DataBindingMode.ExpressionsAdvanced, you can assign a binding expression to a report control:

• Use the ExpressionBinding.EventName property to specify the event handler in which the expression is evaluated.
• Use the ExpressionBinding.PropertyName property to specify the property to which the binding expression is applied.
• Use the ExpressionBinding.Expression to specify a binding expression for the specified property in the selected event handler.
