How to get all selected indices in a datagrid

Question

I have a datagrid with the option SelectionMode = DataGridSelectionMode.Extended.

With that I can select various row.

I would like to know the indices of the selected rows. I am aware that I can get dtg_ExecutionTimes_PpDescriptions.SelectedItems but I am not able to retrieve the indices from that list. For example in the picture it is 1 and 3 (or 0 and 2)

Thanx

There are different ways, if you don't have reference duplicates in your items source (what is usually the case), then you can iterate through the items and get the indexes:

var selIndexes = new List<int>();
foreach (var selItem in dtg_ExecutionTimes_PpDescriptions.SelectedItems)
{
    selIndexes.Add(dtg_ExecutionTimes_PpDescriptions.Items.IndexOf(selItem));
}
