I am using Infragistics UltraWinGrid. The grid is binded to LLBL EntityCollection that has UserGUID,BookTypeGUID, ValidatedDate

I have setup the Grid in following way

UserGUID is a drop down with UserCollection and has DisplayMember =UserName and ValueMember=UserGUID.

BookTypeGUID is a drop down with BookTypeCollection and has DisplayMember =BookType and ValueMember=BoodTypeGUID.

ValidatedDate is DateTimePicker

Everything is fine except when i try to add new row, i get "000-00...s" on UserGUID and BookTypeGUID and '01/01/01' on ValidatedDate.

but once i save it looks ok.

even setting up with grid's default value to DBNull didnt work (i get an error)

I have not tried this with LLBLGen V2 yet. I coulnt get any resolution from Infragistics...so i come here.

whats my solution. how can i get rid of default 0s on GUIDs and '01/01/01' on Date.

I am Using WinForm,Adaptor, VS 2005.

Seems like default values for fields which aren't initialized. Most grids just show an empty cell though.

Thanks for your response Fran, But whe you say most of the Grid,do you also mean for Infragistics's Grid? like i said when i have a default value of DBNull I still get an error. so i can't use DBNull either? is there another way to initialize? This will be huge for me.

Is it possible to define "If value X then value DBNull.Value" ? I'm not familiar with the infragistics grid's technical details.

Have a look at the DataFilter in Infragistics. There you can correct handle this sort of things.
