    hi shl_csit

    first add your java script file into your .aspx page

      <script type="text/javascript" src="../javascript.js" mce_src="../javascript.js"></script>

    then u can call .js file's functions.

    Suppose on a button with id "BtnSubmit"

    BtnSubmit.Attributes.Add("OnClick", "javascript:return Helloworld();");

    refer to the following links also:

    Any particular reason why you don't use the RequiredFieldValidator control?

    Hi,

    create a .js file and put that function within it..

    then refer that path like..

    <script type="text/javascript" language="javascript"  src="../js/myvalidation.js"></script>

    then it is working..

    Thanks..

    first i would recomend u to use

    Required field validator

    then try client side java script validations

    and then server side validation using codebehind.

    cheers

    i use more than 20 textbox in a page. . So i preferred javascript to group the validation. .we can call the function in the button directly. .

    in case of controls it is difficult to group up. .
