how to handle long text in dropdownlist control in ASP.NET
I use VS2010, C# to develop ASP.NET web apps, sometimes my drop down contains long items which makes my combos big, is there any way that I can break large items into 2 (or more lines), so that my combo size is fixed?
You can not make it multiline. Instead you can make dropdown control fixed width and its dropdown(items) resize according to the content length
Try using CSS to add a fixed width to your dropdown, like:
Whilst the dropdown itself will be of a fixed width and may not show all of the text, the option elements should expand to the width of the widest element.
