Namespace: DevExpress.XtraReports.UI
Assembly: DevExpress.XtraReports.v18.2.dll
Declaration
public virtual event BindingEventHandler EvaluateBindingPublic Overridable Event EvaluateBinding As BindingEventHandlerEvent Data
The EvaluateBinding event's data class is BindingEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Binding | Provides the information about a control's bindings in the XRControl.EvaluateBinding event handler. |
| Value | Specifies a new value for a control's bound property obtained in the XRControl.EvaluateBinding event handler. |
Remarks
The EvaluateBinding event is raised before the XRControl.BeforePrint event rises. In this event handler, you can perform custom calculations over data obtained from a control's data source, that for any reason cannot be evaluated via Calculated Fields Overview.
In this event handler, you can access the information from a control's XRBinding object (via the BindingEventArgs.Binding property), and assign a new value to the BindingEventArgs.Value property.
This event does not fire for data fields that are embedded into an XRControl's text using mail merge.
