Hello all,
Im trying to get an update panel to update while I am executin a large process. If I can output to the screen, I will know exactly where the process is up to. For example:
//.aspx
//.aspx.cs
Im the above example, when Button1 is clicked, the update panel is updated without an actual page refresh. However, when the button is clicked I do not see label1 altering value from "TEXT1" to "TEXT2" to "TEXT3", all that I see is "TEXT3" after a short pause (due to the Thread.Sleep commands.).
Any ideals how I could go about updating the text in Label1 while the code in Button1_Click is still exectuting?
I have even tried to add in "UpdatePanel1.Update();" after setting each Label.Text value, however same happens.
Any help would be much appreciated
