Comment on Silverlight DataGrid – Populate Dynamic Columns from a Child Collection by Ari Weinberger

I hit another brick wall. I need the grid to be editable.
If I use a value converter, I don’t have a reference to the original EntityCollection on ConvertBack.

Thanks for the value converter suggestion. It works great!

Thanks again for your help!

Without having your code available it is difficult to help. You could try binding to the object and then using a value converter to get the desired result.

Happy coding.

Thanks for your reply. I tried the following, but it’s not valid syntax.
I tried both [] and () for the index. () throws an error, while [] doesn’t work.
What am I doing wrong?

Thanks again.

dg.Columns.Add(New DataGridTextColumn With {
.Binding= New Binding(“Periods.ElementAt[0].Hours”)})

That is because you cannot apply [] indexing to an EntityCollection. You could try using ElementAt(index).

Hi, I tried to implement this with WCF RIA Services that returns an entity with an EntityCollection as one of its properties (the entity is associated with another in a one to many relationship).
The indexer doesn’t seem to work in this case.
If I bind to the .Count, I get the number of items in the collection, so the data is there.

Any suggestions?

I got it. It must had been some network issues.

I couldn’t download the source. Seems like the zip file is not available.
