In this post I will show you one of the rule which is quite often used in applications is the Range validation, To check the range of the input user control so that user can't enter less or more then the minimum and maximum value respectively. In my previous post I have show you how to use the validation rules you can read it if you don't have any idea about the validation rules.This post is the continuity of the previous post.
Let us start with the range validation rule example. The example code for this example is the same as I have used for the previous post I have added new validation rule with the name of the RangeValidation in the ValidationRules folder, where all the validation rules are placed.In the List 1 you can see the complete class for the RangeValidation rule. Here you can see that I have three properties one for the MaximumLength and MinimumLength for checking the maximum values entered in the user input control and to check the minimum value entered by the user in the input control respectively.
