ASPxGaugeControl.CustomJSProperties Event

Enables you to supply any server data that can then be parsed on the client.

Namespace: DevExpress.Web.ASPxGauges

Assembly: DevExpress.Web.ASPxGauges.v20.2.dll


public event CustomJSPropertiesEventHandler CustomJSProperties
Public Event CustomJSProperties As CustomJSPropertiesEventHandler

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.


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 ASPxGaugeControl's base properties.


Typically, using a specifically introduced ASPxGaugeControl.JSProperties property might be more convenient and efficient than handling the CustomJSProperties event, which is mostly declared for backward compatibility.


This example demonstrates how to obtain server data from the client. A temporary client property - cpDefaultValue, is declared within the ASPxGaugeControl.CustomJSProperties event handler. This property holds the ASPxGaugeControl's default value, specified by the ASPxGaugeControl.DefaultValue property.

protected void ASPxGaugeControl1_CustomJSProperties(object sender,
           DevExpress.Web.CustomJSPropertiesEventArgs e) {
    e.Properties.Add("cpDefaultValue", ASPxGaugeControl1.DefaultValue);
