I have code that will set a drop-down list value to "xyz" and the .Enabled
property to False. However, when I do that I can no longer retrieve the
value "xyz" upon postback. It is as if I set the .Visible property to False
as well and the control wasn't rendered, but I did not. If you View Source
of the rendered HTML, you can see that the control is indeed still intact
(everything is the same except the disabled argument is set to "disabled") .
Why can't I get the value when I disable a control?
Thanks,

Hi Wim,
Is it by design for version 1.1? I am using 1.0 and this is not happening.
Thanks,

What you can do however is to set a hidden form field to the value of the
selectbox just before you disable it, and retrieve that instead. Hope that helps, Wim Hollebrandse http://www.wimdows.net http://www.wimdows.com

It's by design in the HTML spec. ASP.NET versions have nothing to do
with it. Browsers aren't supposed to submit the values of disabled
controls.
Mike,
For a dropdown, you don't set the value like
DropDownList1.S electedItem.Val ue = "xyz". Instead, you do this
DropDownList1.S electeIndex = i; //i is the index of value "xyz" in the
dropdown, starting from 0.
Make sure only set it once in the Page_Load event like,
if(!Page.IsPost Back)
{
DropDownList1.S electedIndex = 1;
DropDownList1.E nabled = false;//you can still get the value on postaback
DropDownList1.V isible = false;//you can still get the value on postaback
}
In the postback, I am sure you can get the value through code like,
string ddlvalue = DropDownList1.S electedItem.Val ue;
It doesn't matter the ddl is enabled or not. The ddl can even be invisible.

So I would like to disable a textbox on a vb.net form

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
