Hi Guys,

I have a label inside an update panel which I wouldl ike to use as a status bar.

Basically the user clicks a button which executes a main fucntion that performs a series of tasks. I'd like to inform the user as to the state of the function as it progresses e.g.:

Stage 1: Retrieving data...

Stage 2: Calculating values...

Stage 3: Printing values...

Stage 4: Done!

I've tried updating the updatepanel directly from the function but it only updates the panel at the end of function (stage 4) and shows "Done!" (which I understand is how it should work).

I've been looking into timers and threads to try and update the panel seperate to the main function but I thought I'd post here incase anyone has any better ideas?

Thanks for any help in advance!

Why updatepanel triggers another updatepanel?

I have two update panels at my ajax page. This is first time I'm using updatepanel and I don't know what is wrong. I think only btnFilter's Click event must trigger the second update panel's content but changing combo values (which also hides/unhides btnFilter button) makes second updatepanel change… >>> More
