dropdownlist for option, but still can type in other options

[kaijanm]

Hello, thanks in advance for any help.

I have a drop down list on a page for a user to select from, but I also need them to be able to type in a value that isn't in the list. 99% of our customers are in NM, so I have a list of NM cities, but I need them to be able to type in a city in another state on rare occasions. This seems like a simple thing, but I haven't yet been able to figure it out.

Thank you!
Kimberly

What I would look into is the theory of two controls - A textbox and a dropdown or listbox.

What I have done in the past is used the textbox value to limit the choices in the listbox but they can type something else in if necessary. OnSelect on the list, I set the value to the textbox.

HTML...

								<asp:TemplateColumn HeaderText="City">				<ItemTemplate>							<asp:Label id="lblCity" runat="server" Width="338px" Text='<%# DataBinder.Eval(Container, "DataItem.City_VC") %>'>						</asp:Label>					</ItemTemplate>						<EditItemTemplate>						<asp:TextBox id="txtCity" runat="server" Width="338px" Font-Size="10px" Font-Names="Arial" AutoPostBack="True" Text='<%# DataBinder.Eval(Container, "DataItem.City_VC") %>' OnTextChanged="GetCityFiltered">
			</asp:TextBox><BR>					<asp:ListBox id="lstCity" runat="server" Width="338px" AutoPostBack="True" DataValueField="City_VC" DataTextField="City_VC" OnSelectedIndexChanged="SetTextField" Rows="4"></asp:ListBox>
		</EditItemTemplate>				</asp:TemplateColumn>

Hope this helps.

Hope everyone is having a great day!

Thanks - Jennifer
