Anyone reported any trouble using DocIO within a UpdatePanel? Actually, I have a button in an updatepanel that I want to generate a report with and the routine is called but the dialog that asks if you want to save or open the created document does not open. Note that the control is created dynamically and it's placed within a DIV tag and then a placeholder. If I put a button manually in the ContentTemplate of the UpdatePanel it works but I really need it inside the Placeholder control.

Just a note that I have a fix for those of you that are having similar problems generating a report in a update panel. I simply changed the server side call when the button is clicked to a client side and then call the __DoPostBack() call to handle the server side code. One advantage to doing it this way is I can determine if my users have run the model (thus we have data) and if not fire a client-side dialog to inform them to run the model first before generating a report.

I'm running into the same trouble trying to produce a pdf document within an update panel at the following line:

doc.Save("Proforma.pdf", Response, HttpReadType.Open)


What is your recommended fix?


Thank you.
