asp.net - Checkbox has values of 0 and -1? -


i have checkboxes on webapp, , save button. when click save button, save checked state of checkboxes database.

when checkboxes not checked, 0's in database. however, when checked, -1's in database. expecting 1's. -1's normal checked states?

sample code:

function processaction(byval checkbox1 integer, byval checkbox2 integer) integer      connection = new sqlconnection(configurationsettings.appsettings("connstring"))      command = new sqlcommand("stored_procedure_name_here", connection)     command.commandtype = commandtype.storedprocedure      command.parameters.add(new sqlparameter("@id", sqldbtype.int, 4)).value = 100     command.parameters.add(new sqlparameter("@checkbox1", sqldbtype.int, 4)).value = checkbox1     command.parameters.add(new sqlparameter("@checkbox2", sqldbtype.int, 4)).value = checkbox2      command.connection.open()     command.executenonquery()     command.connection.close()      return 1 end function

the call:

sub buttonclick(byval source object, byval e eventargs)     processaction(checkbox1.checked, checkbox2.checked) end sub

a lot depend on code in between, boolean true value conventionally represented integer value -1. depends on how handling value before gets persisted. code useful if need further help.

edit: code added shows relying on implicit cast boolean integer, resulting in -1 value. in vb, depending on version, use iif(checkbox1.checked, 1, 0) or if(checkbox1.checked, 1, 0). alternatively, keep value boolean, , save appropriate underlying dbms data type if there 1 - example, in sql server, bit data type.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
