Definition and Usage
The ValidationSummary control is used to display a summary of all validation errors occurred in a Web page.
The error message displayed in this control is specified by the ErrorMessage property of each validation control. If the ErrorMessage property of the validation control is not set, no error message is displayed for that validation control.

Example 1
The following example contains two forms in an .aspx file. The first form has a label with the text "Please enter a number from 1 through 100", an input box to input a number, a RangeValidator control that checks that the input value is a number from 1 through 100, a RequiredFieldValidator control that checks that the input field isn't empty, and a submit button. The second form is activated by the submit button on the first form, and displays a response. If one of the input value did not validate, the ValidationSummary control will display (in a list) the text in the ErrorMessage property for each control that did not validate:
<%@ Page
Inherits="System.Web.UI.MobileControls.MobilePage"%>
<%@ Register TagPrefix="Mobile"
Namespace="System.Web.UI.MobileControls"
Assembly="System.Web.Mobile" %>
<script runat="server">
sub page2(Sender as Object,E as EventArgs)
ActiveForm=f2
end sub
</script>
<Mobile:Form id="f1" runat="server">
<Mobile:Label runat="server">
Please enter a number from 1 through 100
</Mobile:Label>
<Mobile:TextBox id="txt1" runat="server"/>
<Mobile:RangeValidator

MinimumValue="1"
