When I was just about done with the project, they changed there mind and want to be able to select multiple items in the drop down list. Is there an easy way to allow this or do I need to use a List box? I've got 30 drop down list so if I can make an easy change that would be great otherwise, how do you add items to the list box and only show 1 item with scrolling options?

I'm assuming this is a WebForms app.

The DropDownList control doesn't allow multiple selection. You'll need to change to a ListBox. You can show only one item at a time by setting the Rows property to 1. Honestly though, doing that is going to tick off your users because it's going to make it very difficult for them to tell which item(s) they've selected in the list.

Is there a way to make it look like a Drop Down list so that when you select the field it shows 5 items with scrolling like a drop down?

And allows multiple selection? Not that I know of. You'd probably have to build your own control, which seems like a whole lot more work than changing the UI to accommodate a ListBox.

CodeCruiser,

Those look like good examples, but my code is in VB not C#. Do you have any examples in VB?

Thanks.

It really shouldn't be that hard to convert the code from C# to VB.NET. It doesn't hurt to be familiar with the syntax of both languages and be able to at least read them and figure out what they're doing as a lot of code examples on the internet will be in C#.

Or you could just include the C# code in a separate class library project.
