I have some .aspx pages with one master pages. I want to give client side validation to all controls on the .aspx pages. For this i am using jquery validation.(ketchup plugins of validation by ashley on papermashup.com tutorials)

It works properly on .aspx page “Without” master page.
But when am using same code & link files on master page then it is not working.

Code without master page

    I think you are missing the form element on your masterpage with the ID of signup

    — Update

    OK

    Change your input to the following

     <input type="text" data-validate="validate(required ,number, minlength(10) ,maxlength(10))"  name="number" />

    Redownload the ketchup plugin here

    https://github.com/mustardamus/ketchup-plugin/downloads

    and use the following line

    <script type="text/javascript" src="js/jquery.ketchup.all.min.js"></script>

    instead of

    <script type="text/javascript" src="../js/jquery.ketchup.js"></script>
    <script type="text/javascript" src="../js/jquery.ketchup.messages.js"></script>
    <script type="text/javascript" src="../js/jquery.ketchup.validations.basic.js"></script>

    This works for me.
