FilterControlPropertiesEventArgs.Control Property

Provides access to a control, whose properties can be filtered in this XtraReport.FilterControlProperties event’s handler.

Namespace: DevExpress.XtraReports.UserDesigner

Assembly: DevExpress.XtraReports.v22.1.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

public XRControl Control { get; }

VB.NET

Public ReadOnly Property Control As XRControl

Property Value

Type	Description
XRControl	An XRControl class descendant, representing a report control, report band or a report itself, whose properties can be filtered.

Remarks

Use the Control property to determine a control or a band, for which it is necessary to hide some properties from end-users in the End-User Designer, and the FilterControlPropertiesEventArgs.Properties property to manage the list of visible properties.

Example

Handle the static XtraReport.FilterComponentProperties event to remove items from the Properties tab. Note that you should specify the property name. Avoid any confusion between the name of a property and its display name. The following image shows the BackColor property (property name) displayed as “Background Color” (display name):

The following code snippet hides properties in the End-User Report Designer‘s Properties panel:
