Hi,

My problem is with the EntityCollectionBase collectionbase = value as EntityCollectionBase; code ... under the previous version this works fine ... in the 2.5 version (due to the generics) it breaks ...

property is used to fill a custom made datagrid with a llblgen collection need the allownew to disable the empty last row ... setting the allowrow on the collection before assigning the collection to the datasource of the custom datagrid does not work ... nor casting the collection to iEntityCollectionBase and setting the allownew off ...

any ideas?

Thx

Try entityCollection.DefaultView.AllowNew = false

changed (it didnt compile)

EntityCollectionBase collectionbase = value as EntityCollectionBase;

to

IEntityCollection _List = value as IEntityCollection;
_List.DefaultView.AllowNew = true;

But i keep getting the empty row in the grid ...

AllowNew should be FALSE.

Also, most of the time you need to set this in the grid to disable it completely (don't ask me why, some grids want to offer a 'new row' edit line no matter what. )

setting the allownew to false did it ...

fridayafternoon ...

Thx

Ok, all grids work except 1 ...

Binding a grid (detail) to a list box (master) ...

lstLocaties.DisplayMember = "LocaleDesc";
lstLocaties.DataSource = m_currentEntity.LocationCode;
gridLocatieOmschrijvingen.DataSource = m_currentEntity.LocationCode;
gridLocatieOmschrijvingen.DataMember = "LocationCodeLocale";

LocationCodeLocale is a collection on a LocationCode entity ...

Setting the AllowNew property, on the default view of the LocationCode collection, to FALSE does not work here becaus "LocationCodeLocale" is a subcollection ...

How can i solve this? Thx

Is this .NET +2.0 or .NET 1.x?

.NET 2.0

in .NET 2 you can disable the new row from the Grid's properties. (EnableAdding / AllowUserToAddRows)

that would be the easiest solution if it was a DataGridView, unfortunately the previous programmer used an DataGrid wich doesn't expose a AllowNew or AllowUserToAddRows property ...

luckily i found that he manually filled the collection and subcollection ... so i was able to set the DefaultView.AllowNew = false for all the subcollections at the moment they were created ...

thx anyway for your help
