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.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type CustomJSPropertiesEventArgs containing data related to this event.

The following CustomJSPropertiesEventArgs properties provide information specific to this event.
Property Description
Properties Gets a collection of temporary client properties.

Expanded 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 ASPxGaugeControl's base properties.

Note

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

Expanded Example

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