Get value from ASP.NET checkbox

Question

User-1934530859 posted

I don't believe ASP checkboxes have a native value assigned to them. How do I assign and retrive a value from a ASP.NET checkbox.

You can get the value using the IsChecked property:

bool didYouCheckTheBox = myCheckbox.IsChecked;  // returns true or false

The default value is false, unless you specifically set the checkbox to be checked in the markup or in the code behind.

no I mean to have a seperate value assigne to a checkbox like a standard HTML checkbox ie:

<checkbox value="5" checked>

Hi,

what I do in this case, I write a value to a hidden field in the when-check-box-changed trigger, like this:

if mycheckbox.checked then

  myhiddenfield.value = 5

else

  myhidenfield.value = 4

end if

Hope it helps

Regards

Dieter

you are not kidding right

there is no html tag like

<checkbox value="5" checked> 

if you meant just simple

<input id="Checkbox" type="checkbox" name="mycheckbox" value="5"/>

then u can get the value using forms collection

label_Result.text = Request.Form["mycheckbox"]; 

and you will get the value 5 only if that checkbox is checked
