Question

I am using this code ..

 ScriptManager.RegisterClientScriptBlock(control, GetType(Button), "sas", "<script> alert('Inserted successfully');</script>", True)

but html result is :

    <script type="text/javascript">
    //<![CDATA[
    <script> alert('Inserted successfully');</script>
//]]>;

why ?
and do I need to call it only in Page_Load or can do that in button click event ??

Answer 1

The last setting which is set to true is for automatically injecting <script type="text/javascript"></script> tags. Remove your script tags or set that flag to false.
