# LinearGauge Quick Start

Develop powerful and lightweight web applications using ASP.NET MVC controls. Learn more about the ComponentOne MVC controls in ASP.NET MVC documentation.

## Content



The quick start guides you through the steps of adding a LinearGauge control to your MVC web application and set its value. For information on how to add a control, See [Adding controls](/componentone/docs/mvc/online-mvc/addingcontrols).

To accomplish this, follow these steps:

### Create an MVC Application

Create a new MVC application using the ComponentOne or VisualStudio templates. For more information about creating an MVC application, see [Configuring your MVC Application](/componentone/docs/mvc/online-mvc/CreatingaNewProject) topic.

### Add a new Controller and View

**Add a new Controller**:

1.  In the **Solution Explorer**, right click the folder **Controllers.**
2.  From the context menu, select **Add | Controller**. The **Add Scaffold** dialog appears.
3.  Complete the following steps in the **Add Scaffold** dialog:
    1.  Select **MVC 5 Controller - Empty** template.
    2.  Set name of the controller (for example: `Default1Controller`).
    3.  Click **Add**.
4.  A new controller is added to the application.

**Add a View for the controller**:

1.  From the **Solution Explorer**, expand the folder **Controllers** and double click the controller (for example: `Default1Controller`) to open it.
2.  Place the cursor inside the method `Index()`.
3.  Right click and select **Add View**. The **Add View** dialog appears.
4.  In the **Add View** dialog, verify that the View name is **Index** and View engine is **Razor (CSHTML).**
5.  Click **Add**. A view is added for the controller.

### Add the Control

*   From the **Solution Explorer**, expand the folder **Views**.
*   Double click `Index.cshtml` to open it.2.  Replace the default code of the `Index.cshtml` file with the code given below to initialize a **LinearGauge** control and set the following properties:
    
    *   Set the gauge [Value](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.Gauge.Value.html) to **35**. The [Value](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.Gauge.Value.html) property denotes the gauge's current value.
    *   Set the [Min](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.Gauge.Min.html) and [Max](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.Gauge.Max.html) properties to 0 and 100 respectively. The [Min](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.Gauge.Min.html) and [Max](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.Gauge.Max.html) properties specify the range of the gauge. You can add multiple ranges to a single gauge.
    *   Set the Gauge's [isReadOnly](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.Gauge.IsReadOnly.html) property to **False**. The [isReadOnly](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.Gauge.IsReadOnly.html) specifies whether a user can edit the gauge's [Value](/componentone/api/mvc/online-mvc/dotnet-framework-api/C1.Web.Mvc/C1.Web.Mvc.Gauge.Value.html) using a keyboard or a mouse.
    
    ```razor
    @(Html.C1().LinearGauge()
        .Width(500)
        .Height(100)
        .Value(35)
        .Thickness(0.1)
        .Min(0).Max(100)
        .Direction(C1.Web.Mvc.GaugeDirection.Right)
            // Create and Customize Ranges
             .Ranges(items => items
                .Add(item => item.Min(0).Max(40).Color(System.Drawing.Color.Red))
                .Add(item => item.Min(40).Max(80).Color(System.Drawing.Color.Yellow))
                .Add(item => item.Min(80).Max(100).Color(System.Drawing.Color.Green))
            )
    )
    ```
    

### Build and Run the Project

1.  Click **Build | Build Solution** to build the project.
2.  Press **F5** to run the project. 
	> type=note
	> Append the folder name and view name to the generated URL (for example: http://localhost:1234/**Default1/index**) in the address bar of the browser to see the view. Or link the view to the home page.
