Yeah I didn't think it was that.
The StartDate and EndDate properties are actually in App_Code folder because I need them on multiple pages. The dvRowFilter posted is in the actual pages code behind file.
If I create a new property returning DateTime.MinValue in the pages code behind file, and call that property it works.
So, the fact my properties are in App_Code seems to be the problem:
App_Code:
public DateTime StartDate { get { return _StartDate; } set { _StartDate = value; } } public DateTime EndDate { get { return _EndDate; } set { _EndDate = value; } }
Pages code behind:
dvRowFilter.Append(String.Concat("(", ColName, " >= '", StartDate, "' and ", ColName, " < '", EndDate, "')"));
Can you access properties from App_Code like this?
