Hello sir,

              It is a nice post. I have a question that : Validation controls in asp.net validate the form in client side or server side ?So, they are which type of controls ? (Clientside/serverside)
 

Hi,

Actually Asp.Net validation controls first check the validation at client site, and also they set IsValid property on the server side (just after page_load event) which we can use in some page controls event to check weather the page is valid or not .

So its depend upon the way in which you want to use these controls.

Thank You

the video lesson will be great for us !

i would like to add some points .....

asp.net validation controls are server side but still page does not post back. it handles the situtation in backend. if cause validation is true , checks in the client side. and if the browser

javascript is disabled then it perform it through server side. so it is advisable that if we are using server side validation we have to check in the server side

as like

page.validate()

if(page.isValid)

{

//do something

}

Nice article thank you
