Question

    Response.Write("<script  type='text/javascript'> showNotification({message: 'This is a sample Success notification', type: 'success' }); </script>")
End Sub

Answer 1

If you use Response.Write in a page, you will be putting the code before the HTML document itself. This means that it will run before jQuery or any plugin is loaded. (And also that it may cause the page to be rendered in quirks mode, which would probably break the entire layout.)

Use the RegisterStartupScript method to add a script in the page:

Protected Sub SqlDataSource1_Deleted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSource1.Deleted
  Page.ClientScript.RegisterStartupScript(Page.GetType(), "notification", "showNotification({message: 'This is a sample Success notification', type: 'success' });", true)
End Sub
