get row index of selected item in datagrid

Question

I am trying to get the row index for the selected item in a data grid bound to a DataTable.

Here is my attempt (based on this SO answer):

private void ShowRowIndex_Btn(object sender, RoutedEventArgs e)
{
    int editedRowIndex = myDataGrid.Items.IndexOf(myDataGrid.CurrentItem);
    MessageBox.Show(editedRowIndex.ToString());
}

<DataGrid CellEditEnding="PriceListDG_CellEditEnding"  RowEditEnding="MyDataGrid_RowEditEnding" Name="priceListDataGrid" />

Unfortunately I always get -1 as the result.

What are you actually trying to achieve? There's probably a much easier way than trying to port some Winforms style code directly to WPF. — Peregrine, Nov 20 '18 at 08:22

@RameshVerma That's not workung for me since `dg` always `null` — MilvNutt, Nov 20 '18 at 08:32
Wait, your DataGrid is always `null`? How do you expect to find anything then? — ikerbera, Nov 20 '18 at 08:34
@ikerbera No, my datagrid is not null, I wrote that `var dg = sender as DataGrid` from the link that you gave returns that dg is null, I assume that because the lineked answer of you isn't the same problem as mine — MilvNutt, Nov 20 '18 at 08:39
Can you show your WPF code for the grid? Do you have your grid linked to the `ShowRowIndex_Btn` event? — ikerbera, Nov 20 '18 at 08:41

If you want to get the index of the row currently being edited, you can do it directly inside your RowEditEnding event:

private void OnRowEditEnding(object sender, .DataGridRowEditEndingEventArgs e)
{
    var index = e.Row.GetIndex();
}

You need to add the namespace: using System.Linq; – Isma Nov 20 '18 at 09:03
