In case of ajax applications, when you request using javascript, you will get notification of time out and you can modify your page accordingly saying the user with a nice interface that "connectivity issues are there"

In not ajax applications where the browser request the page directly, I dont think you could do more as at the event of timeout, you will not have control over the returned output....

Hi shamcs
              Based on my understand i think your probelm with databse server actually by default our connection with database server is only 30 secs for that reason up to 30 secs queries execute very well after that if quries take more time that will show timeout errors for us.to avoid that problems we can increase command execution timeout like this

SqlConnection con = new SqlConnection("User id=eltp; password=eltp;data source=softsql");
        con.Open();
        SqlCommand cmd = new SqlCommand("Seelct * from table1 where userid= '" + ID1 + "'", con);          
        cmd.CommandTimeout=120;
        cmd.ExecuteNonQuery();
        con.Close();

if that is not the case if your problem related to session time please read this post

Thanks for the reply..but im just wonder if i can handle connection time out by page request...because i have developed one web application

and currently in testing progress..but for what ever reason, sometime server only return the view state code to client, not the page actually client request.i suspect the application actually occur an error and cannor execute the actual page..

i want to handle this error like for example  in this forum..At this morning when i enter  url at my browser "www.forum.asp.net" i get the error page said

"SORRY, an error has occur......."

is it possible..??

I found at Global.asax this line :

Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
        ' Code that runs when an unhandled error occurs
        
    End Sub

How do i configure this thing..??

Thanks in advance

hi shamcs,

for handling all the exceptions ayou need to write try catch blocks to handle all the exceptions and at that time we can display error message page if user gets exception

try like this to like this

Try
conn1.Open()
Execute Command
conn1.Close()
conn2.Open()
Execute Command
conn2.Close()
Catch ex As Exception
    Response.Write(ex.Message());
Finally
End Try
