ASPxFileManager.CustomJSProperties Event
Enables you to supply any server data that can then be parsed on the client.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v24.1.dll
NuGet Package: DevExpress.Web
Declaration
Event Data
The CustomJSProperties event's data class is CustomJSPropertiesEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Properties | Gets a collection of temporary client properties. |
Remarks
In some instances, it is necessary to obtain server information on the client. The CustomJSProperties event enables you to declare temporary client properties. Once declared, a property can be accessed on the client.
To add new properties, use the event parameter’s CustomJSPropertiesEventArgs.Properties property, which represents a collection of property names and their values. The only requirement is that property names must begin with the ‘cp’ prefix, to avoid rewriting the ASPxFileManager‘s base properties.
Note
Typically, using a specifically introduced ASPxFileManager.JSProperties property might be more convenient and efficient than handling the CustomJSProperties event, which is mostly declared for backward compatibility.
