Hello!

Below I have the aspx page and the code behind file.
This question is just for learning.
In the code behind file I have set the HTML server control div property
Disable to true in this way
to DIV1.Disabled = true;
but it doesn't not have any effect. I thought it should disable the working
for this HTML server control.
So my question is why does it still work when I have set the Disable
property to true

contains:" + "</h3>";
//Create an object to move through style collection of the box DIV1
IEnumerator keys = DIV1.Style.Keys.GetEnumerator();
//Move to the next item and write its values untill reach the last

says:

In the browser, a disabled element or control is read-only, with the
following added restrictions: its value is not submitted with the form,
the element or control cannot receive focus, and the element or control
is skipped when navigating the document by tabbing.
