Hi
I am working on a mobile.net project. I am trying to make a list of restaurants which is displayed in a drop down list...whn d user selects an item he can add it to d list of favorites. However i am getting an error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: CS0102: The type 'mobile_rest' already contains a definition for 'emptyChangingEventArgs'
Source Error:
Line 78: {
Line 79:
Line 80: private static PropertyChangingEventArgs emptyChangingEventArgs = new PropertyChangingEventArgs(String.Empty);
Line 81:
Line 82: private int _r_id;
I have no clue why this is happening... is it because i used d same table in another file too?
Here is my code
