In asp .net RequiredFieldValidator use to use to fill some value in given Textbox Means you can not left it Empty.In programming of web development it is impotent at some time that we have some retraction by which user(which use this web page) can not left blank this particular Textbox.| For RequiredFieldValidator Example in asp.net website at the login web page we all wage Enter the Username and password,the developer do not want to processing data in back site or by Query by bank data. Because we know that if you are registers user the you must have your own username and password on this site.Continuous validation of load test suites.so in the web programming we want RequiredFieldValidator for this Regression we give code also. simple you create your asp.net page and copy this code and past on your page. | |
