ListBox style attribute not saved

Anyone with any suggestions?

Where are you putting this code in which event?

normaly u would put it in the Page_load event with in if(!isPostBack){ }

That is what I am doing however attributes are lost onPostBack. This is the problem I am having. Unless there is another way to color individual listbox items without using attributes...

I have tried this with following code with autopostback = true(Do you have your viewstate enabled on this control and parent controls?) and it worked and maintained the style. Please post the complete code if you can.  
private void Page_Load(object sender, System.EventArgs e)
              {
                  // Put user code to initialize the page here

                  if(!IsPostBack)
                  {
                        Label1.Text = "Hello world";
                        lItem.Items.Add( new ListItem("hello","world"));
                        lItem.Items.Add( new ListItem("hello","world"));
                        lItem.Attributes.Add("style", "color: green");
                  }

      }

            private void lItem_SelectedIndexChanged(object sender, System.EventArgs e)
            {
            
            }

Hello,

Thanks for your continued help. I'll clip the code I'm having trouble with shortly, but my routines that populate the listbox are being called from page_load and are not being run again on postback. I'm not too sure what you mean by ViewState (I'm programming in ASP.NET / VB backend) but autopostback is true on all controls having this problem.

What I meant is the  control property  EnableViewState = true, make sure to enforce this.

OK yes EnableViewState is true (default value) on the control in question.

I have created a new page in my solution and written a very basic routine that is also losing the color styles. Here it is:

---------------------- text.txt ----------------------
chg 0123456789
mov QQQQQQQQQQ
get AAAAAAAAAA
new ZZZZZZZZZZ
new WWWWWWWWWW
chg SSSSSSSSSS
chg XXXXXXXXXX
out EEEEEEEEEE
out DDDDDDDDDD
mov CCCCCCCCCC
mov RRRRRRRRRR
get FFFFFFFFFF
get VVVVVVVVVV
chg 0123456789
---------------------- text.txt ----------------------

lstQueue - listbox, autopostback = true, enableviewstate = true
cmdEdit - button, see _click routine below, enableviewstate = true
lblInfo - label for outputting errors, enableviewstate = true
txtEdit - textbox, enableviewstate = true

Also note that I lost the colors (style) if I change the selected index or use the button. Both work incorrectly.

Hi meomar,

Thanks for your solution.

I'm not entirely sure why I never thought of using the listbox to re-apply the colors onPostBack as you have done. This will be the easiest way to solve the problem though. Thanks for taking the time to help me with this. It was much appreciated.

Hey ,

Sometimes  I need another pair of eyes to see my hat that I am wearing and looking for ;-)
