Example

This example demonstrates how to change the ASPxGaugeControl’s value using an ASPxSpinEdit.

Handle the spin editor’s ValueChanged event to call the gauge’s client-side ASPxClientGaugeControl.PerformCallback method. Pass the spin editor’s value as a parameter. As a result, the ASPxGaugeControl.CustomCallback event is raised, and the spin editor’s new value, specified by the e.Parameter property, is assigned to the ASPxGaugeControl.Value property. After a custom callback has been performed, the ASPxGaugeControl is automatically re-rendered.

The animation below shows the result:

    <ClientSideEvents ValueChanged="function(s, e) {
        gc.PerformCallback(s.GetValue());}">
    </ClientSideEvents>
</dxe:ASPxSpinEdit>

                  DevExpress.Web.CallbackEventArgsBase e) {
    ASPxGaugeControl2.Value = e.Parameter;
