Very Nice Tutorial...Tahnks

i am not getting "Validation failed" message when i hit enter without entering value..i am getting only "*" message to enter detailes ...sir please help me

wow great explanation.

better videos

hi,
MY code is the same. But on submitting without validation it does not go to the else part, just shows the error messages.

Please help.

If you're having issue in VS 2013 just put this code onto your page load
protected void Page_Load(object sender, EventArgs e)
{
this.UnobtrusiveValidationMode = System.Web.UI.UnobtrusiveValidationMode.None;
}

Hey, Kudvenkat very nice tutorial, could you make a tutorial on client side validation using jquery and server side validation in one form please..

thanks

Good, thanks

Thanks for taking the time to make this! Much appreciated!! =)

If I understand correctly, ASP fires javascript when validation fails. Is there any place to edit this generated js,so you could for example fadein the errormessage using Jquery?? 

Hi, I am little confused - why does the validation run at client side when the validator control has ' run at = "server" ' property? 

Thank you verry much!!

excellent explanation

Hi, venkat could you please make videos on AJAX Controls. I watched a lot of videos but could not understand any of them because they are not a match to the way you explain. So, please make some videos on Ajax controls venkat. I request please...................

Thank you Venkat for this video, If we disable(Enable = false) the control dynamically, associated validation control still works on button click. Shall we dynamically disable the validation control as well to make it work? Or is there any other way to achieve this?

Thnx Venkat for uploading these videos....1 quick question. Is there any way by which we can select either Clientside/Server side validation. As shown in ur video, only when the Javascript is disabled in the browser the Server side validation takes place....Thnx!

you can add below in the button click event lblMessage.Text = " Name :"+txtName.Text+ " and Gender : "+ddlGender.SelectedItem.Text + " added successfully";
