asynchronous - Async, Azure and program flow -

i have searched forum problem didn't find suited, im having problem program flow.

i have mobileservice on azure has question table, app has main menu , quiz button takes user quiz page, on quiz page have start quiz button shows first question in list.

this code im using questions database, placed in pages constructor , when user presses quiz button there delay in page opening isn't bad not long wait, few seconds, there better way this?

task<imobileservicetable<question>> getdatafromdatabase = new task<imobileservicetable<question>>(getquestions); getdatafromdatabase.start(); questionlist = await getdatafromdatabase; 

in same function have code modifies start quiz button isenabled attribute. stops quiz going forward unless data has came through server, not working time , start button isenabled set true , nullreference mobileservicecollectionview questionlist though task has completed.

task<bool> assigndata = new task<bool>(assigntabletoitems); assigndata.start(); startbutton.isenabled = await assigndata; 

any on appreciated.

thanks

you shouldn't have create new instance of task<t> query database (you haven't provided definition of getquestions used in first code snippet, can't tell whether code doing it's supposed to). you'd typically table appropriate type mobileserviceclient object, , query on it:

var client = new mobileserviceclient(appurl, appkey); var table = client.gettable<question>(); var questionlist = await table.tolistasync(); 

regarding second code snippet, without definition of assigntabletoitems it's hard know you're intending code do.
