Calling function inside a loop but the loop stops - c#

Question

for (int i = 0; i < dt.Rows.Count; i++)    
{                
    function(dt.Rows[i][0].ToString());   
}

I tried to loop the selected values from the gridview and put it inside a datatable. Now, my problem is that when I tried the code above to pass the value from datatable to my function. It works, but just once and the loop stops. Can somebody help me please?

The function is for downloading pdf file.

How many rows dt has. If it runs only one time may be there is only one row in data table. — Bhuban Shrestha

I think the dt is working, when i put break point. It gets the selected values — Bogart

If the function is sending a binary pdf file to the response stream, it may be calling Response.End which would halt the thread.

If you want to send multiple files the client needs to make multiple requests or the server needs to package them up, like in a zip file.

You're right sir, when i remove the Response.End, the error said multiple disposition. now, my problem is I don't know how to put all the pdf into zip then download it.
