I’m working with an aspx page, where once I click on a button, some calls are executed in the background and I display the returned information on the webpage. I do this by adding this information to a panel:

panel.controls.add(label)
panel.controls.add(anotherpanel)

Problem is that once I click the button again, and I get some new objects from the background calls the UI elements (those labels and panels) still remain visible and my new information is just added after the previous one.

I would like to have all the previous information gone once I press the new button.

I’ve tried panel.controls.clear(), but it doesn’t do anything.

Any ideas? Thanks.

    Have you tried setting a breakpoint and check to see that it is not the background calls returning the previous information along with the new ones?

    I asked because items that were added programmatically, by itself, shouldn’t persist across postbacks.
