I'm calling now.. i hope they will do it... – Ofir Hadad Oct 11 '11 at 09:25
Ok. After a long talk on the phone.. It's seems that they are not sure if they have Ajax support on a shared host account. Is there a way to check if I have an Ajax supprt on my Host? btw... could it be a Version problem? – Ofir Hadad Oct 11 '11 at 10:13
yah this problem occur when 1) does not have .net framework 3.5 or more or 2) Ajax Extensions 1.0 no installed in server. – Bhargav Mistri Oct 11 '11 at 10:23
I have .net framework 3.5, Is there any html file that i can run on the host to test the ajax support? – Ofir Hadad Oct 11 '11 at 10:38
no, for this issue you have to test demo which include Ajax Control Tookit like calender extender. – Bhargav Mistri Oct 11 '11 at 10:47
OK. I put an Ajax Control Toolkit Sample Site on the HOST. I have change the file permission to 777 and now i see the Ajax sample site. So i think i have AJAX support on my host... Please refer to this link: http://picit.co.il/Default.aspx So Maybe it's something worng with my Web.config? – Ofir Hadad Oct 11 '11 at 11:50
so now i am sure that ASP.NET 2.0 AJAX Extensions 1.0 is not installed in your server. – Bhargav Mistri Oct 11 '11 at 12:09

You have to ask to your host for ASP.NET 3.5 framework support.

or, if I remember correctly, if using a lower framework (no reason you should be) its installed via the Ajax control toolkit. – cillierscharl Oct 11 '11 at 09:02

Is **Ajax** is installed on server? – KV Prajapati Oct 11 '11 at 09:03
.NET Applications (ASPX) ( .NET UP 3.5 .) I can't Install on the server. But i will check if Ajax is Installed – Ofir Hadad Oct 11 '11 at 09:20

@Ofear - That error/exception itself describes this issue. I'm sure about it. You can add appropriate version of Ajax dll into Bin folder. – KV Prajapati Oct 11 '11 at 10:17
where can i find this Dll file? – Ofir Hadad Oct 11 '11 at 10:37
