Re: ASP Dropdownlist events

[S. Justin Gengo]

Kerri,

Use the drop down's SelectedIndexChanged Event.

You should also set some type of text as the first item such as "Please
Select". If you don't the user won't be able to fire the event for the first
item in the list because the index won't be able to be changed to it (The
first time at least).

Then use a required field validator to keep the user from selecting the
"Please Select" entry. Do so by setting the required field validator's
InitialValue property to: "Please Select".

Sincerely,

Thanks for that.

Thats what I currently have.

Yet my click event is not being called.

Here is my drop down..


<aspropDownList id="selCountry" Runat="server"
style="width: 140px">

<asp:ListItem value="US"
selected="True">US</asp:ListItem>

<asp:ListItem value="Canada">Canada</asp:ListItem>

<asp:ListItem value="Other">Other</asp:ListItem>

</aspropDownList>


and here is the event...


Sub selCountry_SelectedIndexChanged(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
selCountry.SelectedIndexChanged
If selCountry.SelectedIndex = ("Other") Then
txOther.Visible = True
End If
End Sub

Any ideas??

Kerri,

Are you posting back with a button or using the drop down's auto post back?
