    I have page with <asp:updatepanel> and gridview. I am generating radtooltip runtime to show on hover of one of the image in grid.
    The tool tip is containing a link which opens a file. And to open a file I have to use Response.WriteFile.

    I came to know that it always creates issue with asynchronous postbacks like this. As in my case it is updatepanel and radtooltip.
    So when I click on the link in tool tip, it shows the below error.

    Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
    Details: Error parsing near 'GIF89a�<���ӓ�{��'.

    I need both things, the updatepanel and rad tool tip.
    Can anybody provide solution for this ASAP?
