FilterControlPropertiesEventArgs Class

Provides data for the XtraReport.FilterControlProperties event.

Namespace: DevExpress.XtraReports.UserDesigner

Assembly: DevExpress.XtraReports.v23.2.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

public class FilterControlPropertiesEventArgs :
    EventArgs

VB.NET

Public Class FilterControlPropertiesEventArgs
    Inherits EventArgs

Remarks

The XtraReport.FilterControlProperties event occurs every time a PropertyGrid refreshes its list of items in the End-User Designer. The FilterControlPropertiesEventArgs class introduces the FilterControlPropertiesEventArgs.Control property, which provides access to a control whose properties can be filtered, and the FilterControlPropertiesEventArgs.Properties collection which contains a control’s properties, which can be hidden from the Properties window.

Note

FilterControlPropertiesEventArgs objects are automatically created, initialized and passed to the XtraReport.FilterControlProperties event handlers.

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:

            // remove it from the Properties collection.
            filterComponentProperties.Properties.Remove(propertyName);
            }
