ASPxGridView.CustomJSProperties Event
Enables you to supply any server data that can then be parsed on the client.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v25.1.dll
#Declaration
public event ASPxGridViewClientJSPropertiesEventHandler CustomJSProperties#Event Data
The CustomJSProperties event's data class is ASPxGridViewClientJSPropertiesEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Properties |
Gets a collection of temporary client properties.
Inherited from Custom |
#Remarks
In some instances, it is necessary to obtain server information (for instance, the currently active page) on the client. The CustomJSProperties event enables you to declare temporary client properties. Once declared, a property can be accessed on the client.
The CustomJSProperties event is raised every time a grid is rendered on the server to allow a developer to pass required information to 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 ASPxGridView base properties.

#Example
This example demonstrates how to obtain server data from the client. A temporary client property—cpPageIndex—is declared within the ASPxGridView.CustomJSProperties event handler. This property holds the index of the currently active page, and can be accessed on the client side.
protected void ASPxGridView1_CustomJSProperties(object sender,
DevExpress.Web.ASPxGridViewClientJSPropertiesEventArgs e) {
e.Properties["cpPageIndex"] = ASPxGridView1.PageIndex;
