c# - UpdatePanel Timer Trigger not Working -
i trying timer trigger update updatepanel , cannot event fire. examples working basic , not sure need check bottom of this.
i have long running process(about hour) evaluates database content , picks out problematic rows. create page allows user execute process , see progress moves along. when problem rows found, want print info page user can see right away rather waiting task complete.
to thought use updatepanel had timer trigger every second. page accessed admins on private server traffic not concern. not sure best approach, if there way of approaching task should consider, please feel free suggest.
to test concept started example @ updatepanel timer causes panels update. modified things suggested , came code appears below.
when execute code, can select drop down option , second updatepanel update timer never executes. have placed break point on timer1_tick function doesn't hit.
i observed when select item drop down, page_load hit. wasn't expecting function hit when update, should it?

i got bottom of one. in end, came down settings in web.config file.
1 source of confusion test project created didn't need of in web.config file. non-test project more complicated , must have settings cause these additional lines required. curious exact settings cause required, if knows, helpful add discussion.
adding following entries in web.config file corrected situation , allowed updatepanel function:
<system.webserver> <handlers> <clear /> <add name="scriptresource" precondition="integratedmode" verb="get,head" path="scriptresource.axd" type="system.web.handlers.scriptresourcehandler, system.web.extensions, version=1.0.61025.0, culture=neutral, publickeytoken=31bf3856ad364e35" /> <!-- make sure wildcard rules below scriptresource tag --> </handlers> <modules> <add name="scriptmodule" type="system.web.handlers.scriptmodule, system.web.extensions, version=1.0.61025.0, culture=neutral, publickeytoken=31bf3856ad364e35"/> <!-- other modules added here --> </modules> </system.webserver> here link question helpful while troubleshooting in case running same problem: sys undefined
thank posted comments, helpful in keeping me going , making sure troubleshooting correct locations.
