server control simple bindable property

[MrB]

I've made a server control that overrides the dropdownlist control. It has
one new property (ddlLocation) that needs to be databound. All is working
well if I type the databound information into the asp.net html view. see
example below.

<jb:jbddl id=jbddl_court_id runat="server" Width="152px"
DataValueField="court_id" DataTextField="court" svrReadOnly="False"
DataSource='<%# objCase.getCourts() %>' ddlLocation='<%# objCase("Location")
%>'> </jb:jbddl>



However I would like the user to be able to type the databinding information
(objCase("Location")) for the ddlLocation property into the visual studio
property window - the way the datasource property works. when i do that
though, the control does not resolve the objCase("Location") to a number, it
just receives the string 'objCase("Location")'.

Here is the relevant server control code.

<Category("Data"), Bindable(True)> Public Property ddlLocation() as String

Get
Return strddlLocation
End Get

Set(ByVal Value As String)
strddlLocation = Value
End Set

End Property

What do i need to do to make the ddlLocation property act the way the
datasource property does in the vs property window?

Thanks in advance,

Jim
