Hi there,
I have a curious problem I can't seem to solve. I have a list box that gets
filled with data, the user selects an item in this list, then a form view
displays the full details from that list. The problem I have is that the
list box and the form are in different content placeholders, and I can't get
them to work together. I have this code:
<asp:Content ID="Content2" runat="server" ContentPlaceHol derID="SideCont ent">
<p>
<asp:SqlDataSou rce ID="SelectSuppo rtingDocs" runat="server"
ConnectionStrin g="<%$ ConnectionStrin gs:ConnectionSt ring %>"
SelectCommand=" SELECT [ID], [Title] FROM
[tblSupportingDo cs]"></asp:SqlDataSour ce>
<asp:ListBox ID="lbSelectDoc ument" runat="server"
AutoPostBack="T rue" CssClass="ListB ox" DataSourceID="S electSupporting Docs"
DataTextField=" Title" DataValueField= "ID"></asp:ListBox>
</p>
</asp:Content>
<asp:Content ID="Content3" runat="server"
ContentPlaceHol derID="Supporti ngDoc">
<asp:FormView ID="FormView2" runat="server"
DataSourceID="S electedSupporti ngDoc"
<EditItemTempla te></EditItemTemplat e>
<InsertItemTemp late></InsertItemTempl ate>
<ItemTemplate >
<asp:Label ID="PageTextLab el" runat="server" Text='<%#
Bind("PageText" ) %>'></asp:Label>
</ItemTemplate>
</asp:FormView>
<asp:SqlDataSou rce ID="SelectedSup portingDoc" runat="server"
ConnectionStrin g="<%$ ConnectionStrin gs:ConnectionSt ring %>"
SelectCommand=" SELECT [PageText] FROM [tblSupportingDo cs] WHERE
([ID] = @ID)">
<SelectParamete rs>
<asp:ControlPar ameter ControlID="lbSe lectDocument" Name="ID"
PropertyName="S electedValue"
Type="Int32" />
</SelectParameter s>
</asp:SqlDataSour ce>
</asp:Content>
From what I can see, the ControlParamete r, controlID is set to the correct
control. However, when the page is run, I get an error " could not find
control lbSelectDocumen t in controlParamete r ID".
I assume this is becuase they are in different containers. Can I reference
the control from it current location? (at the moment content2 is a side bar,
and content 3 is the main form).
Thanks for any help.
