Property Value

Type Default Description


A string value that specifies the control's value.


The ASPxGaugeControl's value specifies the value or text of the first gauge found, contained within the ASPxGaugeControl.Gauges collection.

The value is calculated as shown below:

  • Digital

    IDigitalGauge dGauge = gaugeControl.Gauges[0] as IDigitalGauge;
    if (dGauge != null)
        value = dGauge.Text;
  • Circular

    ICircularGauge cGauge = gaugeControl.Gauges[0] as ICircularGauge;
    if (cGauge != null && cGauge.Scales.Count > 0)
        value = cGauge.Scales[0].Value;
  • Linear

    ILinearGauge lGauge = gaugeControl.Gauges[0] as ILinearGauge;
    if (cGauge != null && lGauge.Scales.Count > 0)
        value = lGauge.Scales[0].Value;
  • State Indicator

    IStateIndicatorGauge sGauge = gaugeControl.Gauges[0] as IStateIndicatorGauge;
    if (sGauge != null && sGauge.Indicators.Count > 0)
        value = sGauge.Indicators[0].StateIndex;


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

The spin editor's ValueChanged event is handled to call the gauge's client-side ASPxClientGaugeControl.PerformCallback method, passing the spin editor's value. 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:


<dxe:ASPxSpinEdit runat="server" Number="0" Width="157px" Height="21px" ID="ASPxSpinEdit1">
    <ClientSideEvents ValueChanged="function(s, e) {
protected void ASPxGaugeControl2_CustomCallback(object source,
                  DevExpress.Web.CallbackEventArgsBase e) {
    ASPxGaugeControl2.Value = e.Parameter;
