I moved asp .NET project(web application) to another computer. When I tried to build it, it showed this error
The type or namespace name 'DatePickerControl' could not be found in the global namespace (are you missing an assembly reference?)
the code
<%@ Register Assembly="DatePickerControl" Namespace="DatePickerControl" TagPrefix="cc1" %>
<cc1:DatePicker ID="DPDateInInput" runat="server" AllowType="False" DateFormat="d/M/yyyy" StartWeekWithDay="Sunday" />
