Row Count for WPF DataGrid?

Question

How to count or return the last index of a DataGrid row? Apparently there's isn't a DataGrid.Count() property. I searched everywhere and I can't find an answer.

I could create a variable and use i++ as a counter for Row count, but doesn't a DataGrid has a built-in solution?

You shouldn't be counting the datagrid row but the collection of items attached to the datasource — TBohnen.jnr

The real question is what you need it for. If it's databound, like proper WPF, why would you care for a index? — Claus Jørgensen

You can use DataGrid.Items.Count to get the number if items.

Items.Count returns 1 when you Datagrid is editable. This don't work for me.

Try this:

int num=dataGrid.ItemsSource.OfType<object>().Count()

As TBohnen.jnr mentioned you should count the items in the bounded datasource. You can retrieve the datasource by casting dataGrid.DataContext to the appropriate Type (List, IEnumerable, or any other Type) and call .Count on that object. It shouldn't be very hard...

DataContext would usually not be an IEnumerable (or a collection), and IEnumberable doesn't have a Count property.
