By using System.Diagnostics namespace you will count excution time of a method
ex:
Dim st = Stopwatch.StartNew()
methode()
st.stop

VB

Response.Write("<br/> time taken")
      Response.Write((CDbl(st.Elapsed.TotalMilliseconds * 1000000) / 10000000).ToString("0.00 ns"))

may be it will help you

Solution 1

Try this:

C#

DateTime startTime = DateTime.Now;
ViewReport();
TimeSpan timeTaken = DateTime.Now - startTime;

That should do the trick.

But i am guessing he want to calculate the time prior to executing this method so that for the time method is executing he can keep the button disabled.
