Creating a C1RadialGauge control in code is fairly simple. In the following steps you'll add a PlaceHolder control to the page, add an import statement, add and customize the C1RadialGauge, and add the control to the PlaceHolder.

Complete the following steps:

1. In Design view, double-click the page to create the Page_Load event and switch to Code view.
2. Add the following statement to the top of the Code Editor to import the appropriate namespace:

   To write code in Visual Basic

   Visual Basic	Copy Code
   Imports C1.Web.Wijmo.Controls.C1Gauge

   To write code in C#

   C#	Copy Code
   using C1.Web.Wijmo.Controls.C1Gauge;

3. Add the following code to the Page_Load event to create and customize the C1RadialGauge control.        

   To write code in Visual Basic

   Visual Basic	Copy Code
   ' Create a new C1RadialGauge.   Dim C1RG As New C1RadialGauge   ' Set the control's size and value.   C1RG.Height = 200   C1RG.Width = 200   C1RG.Min = 0   C1RG.Max = 100   C1RG.Value = 60   ' Add the C1RadialGauge to the PlaceHolder control.   Dim PlaceHolder1 As New PlaceHolder   PlaceHolder1.Controls.Add(C1RG)   form1.Controls.Add(PlaceHolder1)

   To write code in C#

   C#	Copy Code
   // Create a new C1RadialGauge.    C1RadialGauge C1RG = new C1RadialGauge(); // Set the control's size and value.    C1RG.Height = 200;    C1RG.Width = 200;    C1RG.Min = 0;    C1RG.Max = 100;    C1RG.Value = 60; // Add the C1RadialGauge to the PlaceHolder control.    PlaceHolder PlaceHolder1 = new PlaceHolder();    PlaceHolder1.Controls.Add(C1RG);    form1.Controls.Add(PlaceHolder1);

What You've Accomplished

Run your application and observe that the C1RadialGauge control was created.
