I have a page which has certain required fields.In order to validate them i am using Required Field Validators.

Now on my save button i have added the attribute
btnSave.Attributes.Add("OnClick", "return OnSaveClick();");

function OnSaveClick()
{
if(document.getElementById('ctl00$ContentPlaceHolder1$txtOneTouchUserName').value.length >0 && document.getElementById('ctl00$ContentPlaceHolder1$txtOneTouchPassword').value.length >0)
{
if(window.confirm("Are you sure you want to save configuration settings and log off ?"))
return true;
}
}

This java script function basically displays a Confirmation box ...

Now , the problem is that when i click save post back occurs and then the .net validation occurs, in case i dont add the HTML onclick event to the save button then the validation occurs without post back.

How do i prevent post back without removing the onclick java script.

When i click save button postback occurs even though validations are in place.

What i have noticed is that if i dont add the javscript function to the save button no post back occurs and the validations work as they are supposed to but then i cant get the confirmation message.

But if i use JavaScript function , the page posts back and on refreshing the validations show up .

One solution i came up with was to remove "Return" from "Return OnSaveClick()"
But in this case if i click "Cancel" the post back occurs.

Make sure that your required field validators are ClinetScriptEnable=true
BTW what validation are firing after post back

Yes i have done that still the post back occurs.
Required Field Validators are firing after post back....which fire before post back in case java script function is not added

Yes when you are attaching the javascript to button then validations at the client side will not fire as you are returning the bool from the function because of that validation of client side are not firing you can check by just by commenting all return from javascript function and from registration in PageLoad. I think its clear now ?

If you use javascript then validator controls will not file.

Can anyone tell one which validator control I have to use to check for
some controls which should accept alphabets only,
Some controls which should accept numbers only,
Some controls which should accept alphanum only,
Some controls which should accept floating type only,

Please tell me which validator I have to use for the above requirement and how it should be used in ASP.Net 2.0 in Visual Studio 2005
