radalert problem in a postback

[Juan]

hi at all

i have a problem with the radalert

i want show a radalert after  postback, i can  but my problem is that the radalert
continuous showing in each postback or if i push on the update page button.
my code is this

on the server
//I use this because a iam using a RadAjaxManager   
 RadAjaxManager1.ResponseScripts.Add("Sys.Application.add_load(pru);")

on the client

function pru()
{
    var owdn=radalert("say something");
    owdn.add_close(clean);
}
function clean()
{
    Sys.Application.remove_load(pru);
// this function is solution to my problem , but isn't  complete because if i press a //update button, the radalert come back again¡
}
what can i do ? what's wrong ? iam programming on visual basic 2005

Hello Juan,

This happens because you have added the script that shows the alert to the RadAjaxManager's ResponseScripts collection. To avoid it, you need to implement a server-side check that will add the script only when needed and to clear it after that.

Can you provide some technique of checking and clearing on the server side?
It seems after adding it on a button event then after postback, it script count is always 0.

RadAjaxManager1.ResponseScripts.Add("Sys.Application.add_load(function(){radalert('Not Available Yet');});")





            If RadAjaxManager1.ResponseScripts.Count > 0 Then
                RadAjaxManager1.ResponseScripts.RemoveAt(0)
            End If

I found this example in the KB article.

RadAjaxManager1.ResponseScripts.Add("(function(){var f = function(){radalert('Welcome to RadWindow Prometheus!', 330, 210);Sys.Application.remove_load(f);};Sys.Application.add_load(f);})()")
