Disable a checkbox in javascript and recognize it as checked on the server side

Question

I have a checkbox which in some cases may be disabled and checked using javascript, i.e:

var cbTest = document.getElementById("CheckBoxTest");
cbTest.disabled = true;
cbTest.checked = true;

However, when sending a postback, CheckBoxTest.Checked is false on the server side.

Is it possible to disable the checkbox and still have the server side recognize it as checked?

Answer 1

Any disabled control inside a form will not submitted to server on post back. You can add a hidden input control and put the checkbox state to that input and server side check that hidden input value.
