help with c# script

Question

I am running a C# Web App that is in a for loop performing some work. The code is running on the server. I added the following code to try to display a running count to the user. I only want the count to update every 100 cycles.

// display running count to user
msgCnt += 1;
if ((msgCnt % 100) == 0) lblCount.Text = "Count: " + msgCnt;

The count does not display until the loop ends and the page gets posted back to the browser. It may be several minutes until the loop finishes and I need to keep the user updated on the progress.

How can I display the count in a label while the loop is running???

I looked into Client-Callback but I only found examples where a user has to click a button.

Thank you.

you have a misunderstanding of how the client-server web sites work. The browser requests the page and the server sends the entire HTML in one request. The server will only send the HTML when the server has completed doing any work that it had to do. Therefore the server will not send a response in the middle of it's workload. to do this you would probably need to do some javascript and have it update the counter. you could probably do a search for asp.net javascript counter and find some good examples.
