viewstate on controls that are not enabled ?

[Adrian Parker]

Trying to write a page with several controls on it, some of which, depending
on the process login, are enabled and some disabled. When I click on a save
button to cause a postback event to fire, the controls that are not enabled
don't have their data returned, so in the UpdateClick event, the controls
contain nothing.

How do I get it to maintain the state even for these columns ?

thanks
Adrian

the browser does not postback values for disabled fields. you will need
client script to copy the values to a hidden field. if you disable them in
the code behind, save their disabled value in viewstate, then restore it on
postback.

Is there any easier way of not allowing entry of fields apart from setting
enabled to false ?

Hi Adrian,

I think Bruce's suggestions are reasonable since disabled html input fields
won't post back their values. And there hasn't any better means other than
copy and store the values into other place(viewstate or sessionstaet)
before disabling the entry fields.

BTW, is it possbile that we don't disable them? For some control such as
TextBox( <input type=text ... ), we can set it's "readonly" attribute. For
example:

txtName.Attributes["readonly"] = "true";

the above statement make the txtName (a textbox control) readonly( can't
change its text), but its value can still be posted back to server side.
In addition, we can also consider settting those control's Visible to false
so as to hidden them.

Hope helps. Thanks,
