We have bought newest version of OpenAccess ORM last week.Version 2009.3.1119.2. I am working on Windows 7.
I've download the c# version of Sofia Car Rental application form your code library. I 've created the related database by using the db script supplied by you in the code package.
But it is impossible to see the application runnig. I ve an error like:
Exception of type 'Telerik.OpenAccess.SPI.Util.QueryExceptionHelper' was thrown
. I've looked everywhere. I found a forum topic sent on May 5. It says that:
The problem occurs because the RadGrid is always reporting null as old values per default. This leads to a comparison from null to "" which is false and generates the exception. This has been fixed now.
To get a working application immediately you should specify ConvertEmptyStringToNull=false in all your editable grid columns.
<telerik:GridBoundColumn DataField="Name" HeaderText="Name"
SortExpression="Name" UniqueName="Name" ConvertEmptyStringToNull=false>
But that was not worked for me..any idea?
