Question

Please look at this code and find out why it isnt working. I am not getting an alert in the webpage. But, the console.writeLine beneath it is getting executed.

    private void PublishLoop()
    {
        while (Running)
        {          
            Thread.Sleep(5000);
            dtMessages = (String)(Cache.Get(key));
            if (dtMessages == null)
            {
                //publish here
                dtMessages = LoadMessages();
                System.Diagnostics.Debugger.Log(0,null,dtMessages);
                Page.ClientScript.RegisterStartupScript(this.GetType(),"ClientScript", "alert('hi');",true);
                Console.WriteLine(dtMessages);
            }
        }

     }

Edit: You can actually only register one unique key per response. You’re running this line of code inside a while loop, so it keeps registering the same key. You need to give it a unique key parameter each time you call this function. In your case, maybe you can have a counter in your loop and append it to your key string

int i = 0;
while (Running)
        {          
            Thread.Sleep(5000);
            dtMessages = (String)(Cache.Get(key));
            if (dtMessages == null)
            {
                //publish here
                dtMessages = LoadMessages();
                System.Diagnostics.Debugger.Log(0,null,dtMessages);
                Page.ClientScript.RegisterStartupScript(this.GetType(),"ClientScript" + i.ToString(), "alert('hi');",true);
                Console.WriteLine(dtMessages);
                i++;
            }
        }
