I have a screen that is trying to search a listbox both by FindByText
and FindByValue. The FindByValue is working find, but the FindByText is
not finding anything. This is even if I copy the text directly from the
source page and paste it into the textbox to make sure I have no typos.
Here is the screen:

<%@Page Explicit="True" Language="VB" Debug="True" %>

<script runat="server">
Sub OK_Click(Sender As Object, E As EventArgs)
Dim Total, ItemIndex As Integer
Message.Text = "You chose:<br>"
Total = 1000
For ItemIndex = 0 To PCOptions.Items.Count -1
If PCOptions.Items(ItemIndex).Selected = True Then
Message.Text = Message.Text & _
PCOptions.Items(ItemIndex).Text & "<br>"
Total = Total + PCOptions.Items(ItemIndex).Value
End If
Next
Message.Text = Message.Text & "Your total is $" & Total
End Sub
Sub Find_Click(Sender As Object, E As EventArgs)
Dim FoundItem As ListItem
FoundItem = PCOptions.Items.FindByText(FindText.Text)
if Not isNothing(FoundItem) Then
Message2.text = FoundItem.text
else
Message2.text = "Nothing found for - " & FindText.Text
end if
End Sub
Sub Find_Click2(Sender As Object, E As EventArgs)
Dim FoundItem2 As ListItem
FoundItem2 = PCOptions.Items.FindByValue(FindText2.Text)
if Not isNothing(FoundItem2) Then
Message3.text = FoundItem2.text
else
Message3.text = "Nothing found for - " & FindText2.Text
end if
End Sub

The routine at issue is the "Find_Click" routine. The "Find_Click2"
routine works fine.
I can't see where I have screwed up (but I'm sure I have - I just can't
seem to find it).
Thanks,
Tom.
