# ASP.NET Mobile Form Control

Complete ASP.NET Mobile Reference

## Definition and Usage

The Form control defines a container for mobile controls.

Each mobile page must have at least one Form control, and each Form control can have a number of mobile controls.

Note that mobile pages can have multiple Form controls. This is due to the nature of mobile devices. Mobile devices have small screens and it is very normal to navigate between screens with simple links.

### Example 1

The following example has one form control, and it will display "Hello W3Schools" in a Label control in an .aspx file:

    <%@ Page
    Inherits="System.Web.UI.MobileControls.MobilePage" %>
    <%@ Register TagPrefix="Mobile"
    Namespace="System.Web.UI.MobileControls"
    Assembly="System.Web.Mobile" %>

    <Mobile:Form runat="server">
      <Mobile:Label runat="server">Hello W3Schools
      </Mobile:Label>
    </Mobile:Form>

### Example 2

The following example will declare two forms in an .aspx file. The first form has a label with the text "Age?", an input box to input the age, and a submit button. The second form is activated by the submit button on the first form, and displays a response:

    <%@ Page
    Inherits="System.Web.UI.MobileControls.MobilePage"%>
    <%@ Register TagPrefix="Mobile"
    Namespace="System.Web.UI.MobileControls"
    Assembly="System.Web.Mobile" %>

    <script runat="server">
    Dim age
    Sub AgeClick(sender As Object, e As EventArgs)
    age=text1.Text
    ActiveForm=Form2
    End Sub
    Sub Form2_Activate(sender As Object,e As EventArgs)
      message.Text="You are " & age & " years old"
    End Sub
    </script>

    <Mobile:Form id="form1" runat="server">
      <Mobile:Label runat="server">Age?</Mobile:Label>
      <Mobile:TextBox runat="server" id="text1" />
      <Mobile:Command runat="server" OnClick="AgeClick"
      Text="Submit" />
    </Mobile:Form>

    <Mobile:Form id="form2" runat="server"
      OnActivate="Form2_Activate">
