Asp.Net RangeValidator Control

The RangeValidator Control :

In this post,we are leaning about ASP.NET RangeValidator Control. RangeValidator control is we can use when we want the user input in between any range of any values. Force to user enter value between a certain minimum and maximum value range. If associate control have no value then this control not works. It is use with RequiredFieldValidator control. We must set five properties when using this control:

Syntax:

<asp:RangeValidator ID="RangeValidator1" runat="server" ControlToValidate="txtAge" 
  ErrorMessage="Invalid Age" MinimumValue="18" MaximumValue="80" Type="Integer" />

The RangeValidator has six important properties:

Sr.No	Property	Description
1)	ID	Set the uniqe value to control to access in code-behind code.
2)	ControlToValidate	which control is check or The ID of the form field validated.

4)	MinimumValue	The minimum value of the validation range.
5)	MaximumValue	The maximum value of the validation range.
