Hi,

Please check and rectify few things mentioned below.

XML

Are you including the jQuery script file into this page? That might explain issues with error messages about the "$" variable.

Use click() instead of onclick() to fire click events. onclick is a handler that is fired when the element is clicked, but is not used to initiate the event itself.

The element's id might not be what you have defined in the page due to ASP.NET namespacing and its goals of ensuring unique element ids on the client. An easy way to figure this all out is to View Source on a rendered page and find your button and its "real" id.

As mentioned in the comments to this post, the jQuery script must referenced by the page via a <script> tag for the jQuery functions to work.

Also don't forget to clear your browser's cache.

Thanks

Solution 2

When you get an error always say what line the error is on.

I wouldn't bother spending any time on this TBH, as you are using the .net validator controls just add EnableClientScript="true" attribute to your asp validator controls and .net will generate the js for you.

error is coming at <form....> tag.

Don't bother with your own javascript, use the client script generated by the validation controls you're already using.

<asp:RequiredFieldValidator ID="rfvCPwd" runat="server" EnableClientScript="true" ControlToValidate="txtUName" ForeColor="Red" ErrorMessage="This field should not be an empty field" />
