Hi, i use ES in the version 2009.1.0209.0 and i try to bind appointments out of a oracle-table into an Infragistics UltraCalendarInfo. After declaring the "SubjectMember" i got the following exception: Code: System.Exception was unhandled Message= "In current data source there is no column named: BETREFF...

Loving ES but still finding the trip a bit intimidating. Was calling LowLevelBind() to bind a query to a repeater. After reading another post I realised I was referencing the wrong Core dll (i.e. NOT the one in the 'Web' folder). Changed this. I can now reference query fields not in the base Entity but...

I suspect I'm just talking to myself here. But I do hope somebody else finds all this useful at some point. There is one part in all of this I still don't understand: If you have a DataGridView bound to an entity collection (like my PhoneCollection)... ...and then you grab a single item from the collection...

David is spot on as per usual;) I deal with this in ASP.NET databinding all the time. For instance there is a combo box of widgets. The client will quite often want the top choice to be -Select One-, or All Widgets. As stated if you actually databind you cannot add these at runtime, it will throw an...

I would like to see the generated entity classes implement the INotifyPropertyChanged interface and all properties notify via the event when they have changed. This is a huge time saver when databinding in windows as it means that bound controls are automatically updated if any property they are bound...

This is a request. I am on a team writing a Window Forms project using databinding and ES. The combination works great. The only issue currently is when there are no rows in the collection and I want to add the first. What is the best practice for adding the first row? Here is my current code: On form...
