I have a couple of comboboxes on my page.
My data model is such that each dropdownlist has an unknown value.
I want to preselect the value unknown on a new record but I do not want to allow the user to select it from the list.
Is that possible?
I can change the value unknown to 'Please Select One' while getting the values from the database.Can i display it like <please select one> with the '<' and '>' .I only want to do it for this particular value so that rather than looking like a value in the list it looks like a prompt. I need to have that value in the list at all times though because I create a new record using those values.
I hope I am making sense.

I am sorry if I am creating a confusion.
The value 'Unknown' belongs to the table in the database.
At first I create a record when the user clicks an add new button and assign the value 'Unknown' to the record.
But that is only to create a record.(the value unknown is there to tie up any orphaned records for future)
What I want is either display 'unknown' as <Unknown>(or <Select a Value> as I can change the text while retrieving the record from the database) so that though it's a value in the database it does not appear as one to the user.
If i change the text in my stored proc to have the '<' and '>' the dropdown list doesn't drop anymore.
Or if that's not possible I am hoping if there's a way so that the user cannot select that value from the list.

Hi newbie,
In this case you can subscribe to the OnClientSelectedIndexChanging client-side event and cancel the event if the user has selected the unknown item.
In any case, you should be able to put the < and > signs as a text of a combo item.
