还有其他有用的属性：

This is the solution I found, when selection unit is "cell" and you need to loop through the selected cells, getting row and column index. I have a DataGrid with textcolumn only, and a datatable (creted from a csv file) as itemssource.

For Each cell As DataGridCellInfo In dataGrid1.SelectedCells
MsgBox(cell.Column.DisplayIndex)
MsgBox(dataGrid1.Items.IndexOf(cell.Item))

I had the same problem with the row index, and the answer given by BR1COP was the only one that worked for me. I didn't use the loop as I only needed the index of one cell, any selected cell. So I used it like this:
我在行索引方面遇到了同样的问题，BR1COP 给出的答案是唯一对我有用的答案。我没有使用循环，因为我只需要一个单元格的索引，任何选定的单元格。所以我是这样使用的：
DataGridCellInfo cell = myGrid.SelectedCells[0];
int rowIndex = dividingGrid.Items.IndexOf(cell.Item);
