before I begin, there is another question with a similar title and it is unsolved but my situation is pretty different since I am using Ajax.
I recently added a label to my Ajax UpdateProgress control and for some reason my asp.net page is not reading it. My original goal was for the text of the label to be constantly be updating while the long method runs. I am using code behind, and I believe the label is declared. I will post my .cs page if anyone would like to read through it (its not too long), All my other labels work perfectly and even if I take the label OUT of the ajax control it will work fine (not the text updates though). Is there a certain Ajax label I need to use?
Im pretty confused why the error is occurring. The exact error message states : “The name ‘lblProgress’ does not exist in the current context. Im using c#, ajax controls, a asp.net page, and visual studio. This program uploads a file to a client and stores the information in a database. If anyone can help I would really appreciate it. Thanks in advance!

If the Label is created inside the UpdateProgress control, then you will need to do something like this
