ValidationCompareOperator Enumeration

.NET Framework 2.0

Specifies the validation comparison operators used by the CompareValidator control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

public enum ValidationCompareOperator

public enum ValidationCompareOperator

JScript

public enum ValidationCompareOperator

Members

	Member name	Description
	DataTypeCheck	A comparison for data type only.
	Equal	A comparison for equality.
	GreaterThan	A comparison for greater than.
	GreaterThanEqual	A comparison for greater than or equal to.
	LessThan	A comparison for less than.
	LessThanEqual	A comparison for less than or equal to.
	NotEqual	A comparison for inequality.

Remarks

The ValidationCompareOperator enumeration represents the comparison operations that can be performed by the CompareValidator control.

Note
Unlike the other operators, DataTypeCheck is a unary operation. Only the data type of the input control being validated is checked. If the ControlToCompare or ValueToCompare properties are set when this operation is used, those values are not checked.

Example

JScript

<%@ Page Language="C#" AutoEventWireup="True" %>
 
<html>
<head>
   <script runat="server">
 
      void Button_Click(Object sender, EventArgs e) 
      {
 
         if (Page.IsValid) 
         {
            lblOutput.Text = "Result: Valid!";
         }
         else 
         {
            lblOutput.Text = "Result: Not valid!";
         }

      }
 
      void Operator_Index_Changed(Object sender, EventArgs e) 
      {

         Compare1.Operator = (ValidationCompareOperator) ListOperator.SelectedIndex;
         Compare1.Validate();

      }

      void Type_Index_Changed(Object sender, EventArgs e) 
      {

         Compare1.Type = (ValidationDataType) ListType.SelectedIndex;
         Compare1.Validate();

      }
 
   </script>
