Question

Difference between onclick() and onClientClick()?

Answer 1

A:

However you get your client side click event registered it doesn't matter. Though if you are using a server control then you do want to use onclientclick. But the key is that you want to use return Validate(). Then in your validate method you return a true or false value depending on whether it validated or not.

EDIT: So make onclientclick look like this:

onclientclick="return Validate();"

Then in the validate function:

function Validate()
{
    return true;
}

@Sangram that's correct, if Validate() returns false, the click event will be cancelled

Answer 2

A:

I have to go find the example...but I just did the on-click event. In the codebehind, I ran my ServerSide code...or I would register a script on the page to call the JS validation and then run the codebehind code.

Learn about RegisterStartupScript

OnClick="MyCodeBehindMethod()"

Then, in the codebehind have:

    //Verify and validate conditions
    string script1="<script language=JavaScript>"
    script1 += "Validate();"
    script1 += "</script>"
    Page.RegisterStartupScript("clientscript",script1);
