Step 1. Create a New Project and Add a Gauge Control

This step describes the common actions required to add a Gauge control to your application.

  • Create a new ASP.NET Web Application project or open an existing one.
  • Add the ASPxGaugeControl component to your project. To do this, drag the ASPxGaugeControl item from the Visual Studio Toolbox (in the DX.22.2: Data & Analytics tab) to the form.

    Lesson_Add a Gauge

    This creates a new ASPxGaugeControl.

    <body>
        <form id="form1" runat="server">
        <div>
    
            <dx:ASPxGaugeControl ID="ASPxGaugeControl1" runat="server" Height="250px" 
                Width="250px">
            </dx:ASPxGaugeControl>
        </div>
        </form>
    </body>
    

Step 2. Run the Preset Manager

  • Click the Gauge’s smart tag and select Run Preset Manager.

    This invokes the following wizard:

    Lesson-Preset Manager

    Note that after you drop the Gauge in the previous step, the Gauge Preset Manager may be invoked automatically (if its “Show the preset manager every time a new Gauge control is dropped onto the form” option is enabled).

Step 3. Load the Required Gauge Preset

  • In the Preset Manager, click CircularFull to display presets with circular gauges.

    Do one of the following to load the gauge preset:

    • double-click the required preset in the Preset Manager;
    • select a preset and click the Load button at the bottom of the Preset Manager.

    The following image shows how to load the Ice-Cold Zone preset using the second technique.
