Silverlight Datepicker empty -

-

i have silverlight date picker declared below

<controls:datepicker  x:name="datefrom"  grid.column="1" grid.row="0"></controls:datepicker>

and button declared such.

<cc:nexbutton x:name="submit" horizontalalignment="right" grid.column="0" content="search" mouseleftbuttonup="nexbutton_mouseleftbuttonup" ></cc:nexbutton>

when type date in date picker , press search button without clicking out of control go nexbutton_mouseleftbuttonup event.

when try , value out going datefrom.text "" , when try , access selectedvalue going datefrom.selecteddate today's date. both of these cases wrong , should getting date entered. thought might of been date validation error have tried different date formats such , uk date formats.

why can not access date entered when not click/ tab out of control? event failing fire.
