Hello there...

I am using dropdonwlists in ProductAttributes.ascx user control.
The dropdownlists are being realted to each other,when Quantity is selected from Quantity combo related dropdownlists of card thickness,magnetic stripe are selected.

Now what i am doing here is, Card thickness combo has two values of "30 Mil" & "20 Mil",when "30 Mil" is selected then other dropdownlist "Magnetic stripe " is created..
On "20 Mil" value of "Card THickness" dropdownlist "Magnetic stripe " gets disabled..
I have added hard coded values of all drop down lists as "Please Choose" like

ddlAttributes.Items.Add(new ListItem("Please Choose", "0"));

Now is it possible to remove Warnings on  "20 Mil" value of "Card THickness" dropdownlist "Magnetic stripe "
