I am running into an issue on a page.  I am trying to use an updatepanel.  Everything works as it should until I comment out my test code that is setting the vaules of some textboxes and have them be filled by a simple Request.

 The updatepanel has a button that resides outside of it that is defined as an asynpostback trigger.  it then dynamically generates a bunch of fileuploaders based on a number supplied.

To debug things further i added a simple command to the button that no longer works when i have requests.  a simple text setting for a label does not go through, so my guess is the button event is somehow being ignored, but why?

 
simply put...

this line:

t_report.Text = mydb.get_fmdesc(Request["fmtype"]);

 as opposed to:

t_report.Text = mydb.get_fmdesc("S");

 
causes the breakage of the updatepanel asyncpostback

last note:  removing the trigger for the updatepanel [and as a result refreshing the whole page] works just fine, but is obviously not what is desired.

Any feedback would be greatly appreciated.

Thanks


 

Not sure of your issue without seeing your code.  You may want to check out http://www.asp.net/AJAX/Documentation/Live/overview/UpdatePanelOverview.aspx for how to use the UpdatePanel and Triggers.

Also, make sure AJAX is setup correctly in your app: http://blogs.visoftinc.com/archive/2007/09/23/asp.net-ajax--updatepanel-not-working--common-problems.aspx

 Thank you for the quick reply.  I was able to find a fix, though it still makes little sense.  I moved the variable setting via a Request to a conditional on pageload for postback or not [so it would only occur the first time].  This solved my problem, but I see no reason why it would.
