Local Resource not being read from database

Question

I created a Customer Resource Provider for my project. 
This provider is executing properly for Global resource requests (see sample #1 reference below). 
However, for Local resource references (see Sample #2 below), it is not loading anything.  Can anybody help out or spot what is wrong?
Sample #1:
<asp:Label
ID="lblAmount"
runat="server"
Text="<%$
Resources:TestResource, Total_Amount_is %>"></asp:Label
>
Sample #2:
<asp:TextBox
ID="txtMoney"
runat="server"
meta:resourcekey="txtMoneyResource1"></asp:TextBox>
Here is the Customer Provider code:

Hi Daniel Rose01,
Based on your description, this issue is related to the Web development, am I right?
Since the ASP.NET has his own support forums, so if it is related to the web project, I suggest you post this issue to the ASP.NET forum, and there you would get dedicated support.
