c# - Set Datetimepicker date NaN -

i have datetimepicker , save date selected save button in sqlserver code. reason need have nullable datetime:

clienteadd.datalead = string.isnullorempty(form["datalead"]) ? (datetime?)null : datetime.parse(form["datalead"]); 

the save function works fine, problem when set datetimepicker loaded. recover data sqlserver code:

var elemento = new{ datalead = clientelead.datalead } 

i sent 'elemento' view jquery , set datetimepicker:

$('#datalead').datepicker('setdate', (new date(result.datalead))); 

when set 'datalead' have nan date. know problem conversion of datetime don't know how save , after load data.

thanks all

from docs here, javascript's date object can recive either milliseconds number or datestring. guess result.datalead object since datalead object (a c# datetime). that's why can't assignment want.

the answer here explains how millis datetime.

try following code (untested):

var elemento = new{ datalead = (long)clientelead.datalead.totalmilliseconds } 

and regular assignment:

$('#datalead').datepicker('setdate', (new date(result.datalead))); 

update:

since clientlead.datalead can null have make sure won't nullpointerexception when doing (long)clientelead.datalead.totalmilliseconds , maybe consider checking typeof result.datalead != "undefined" in javascript
