How can I select multiple values in dropdownList in asp.net with VB

Question

I am creating a page in which I need to show a drop down List. From this drop down List a user can select multiple values. I know I could use a check box list like:

<asp:CheckBoxList ID="CheckBoxList1" runat="server" style="margin-right: 158px">
    <asp:ListItem>Value 1</asp:ListItem>
    <asp:ListItem>Value 2</asp:ListItem>
    <asp:ListItem>Value 3</asp:ListItem>
    <asp:ListItem>Value 4</asp:ListItem>
</asp:CheckBoxList>

but if there are more than 50 or so values then that will consume a lot of space on the page and will look odd. So kindly tell me how can I select multiple values from drop down list or if there any alternatives so that I can select multiple values and show many records on a minimum space but not a grid?

I think what you are looking for is a ListBox. What you will want to do is apply CSS to allow it to scroll horizontally.

you can use List box control with the SelectionMode property set to Multpile. Listbox

if you need dropdownList only, then you can check this example Multi Select DropDown
