Solution 1

In the scenario you proposed (both the operation in the GUI thread) you cannot do that.
In order to properly do that, you should move the for loop in a worker thread.
See, for instance "Multithreading in Windows Forms Controls"[^].

You are right, I missed the ASP.NET tag. in any case you have to use a similar approach.

See I did a solution in asp.net
Code are following below

C#

Thread thLoop = null;
    static string value = "";
    static bool isStopRequired = false;
    protected void Button1_Click(object sender, EventArgs e)
    {
        isStopRequired = false;
        value = "";
        thLoop = new Thread(new ThreadStart(GetLoop));
        thLoop.Start();
    }
    void GetLoop()
    {
        for (int i = 0; i <= 50000; i++)
        {
            value += "  " + i.ToString();
            if (isStopRequired) break;
        }
    }
    protected void Button2_Click(object sender, EventArgs e)
    {
        isStopRequired = true;
        if (thLoop != null) thLoop.Abort();
        Response.Write(value);
    }
