Definition and Usage

The TextBox control is used to create a single-line input box on a mobile device.

The text can be specified by the text attribute or as the content of the TextBox element. If the text is specified in both ways, the inner text takes precedence. However, if the text is programmatically set, the inner text is replaced with this text.

The following example will declare two forms in an .aspx file. The first form has a label with the text "Age?", a textbox 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"
