Copy WPF DataGrid selected rows to clipboard using CopyingRowClipboardContent

Searched high-and-low for this code that properly used of a DataGrid event method signature associated with the DataGridRowClipboardEventArgs. Clipboard.SetText can be flaky, not grabbing/setting the clipboard all the time. 

Set "FullRow" at the SelectionUnit mode for dataGrid called myDataGrid

1	<DataGrid x:Name="myDataGrid" SelectionUnit="FullRow"></DataGrid>

We have a method myDataGrid_CopyingRowClipboardContent that gets called for each row in the dataGrid to copy its contents to the clipboard. For example,for a datagrid with 10 rows this is called 10 times.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

public int clipboardcalledcnt { get; set; } //CopyingRowClipboardContent invoked count private void myDataGrid_CopyingRowClipboardContent(object sender, DataGridRowClipboardEventArgs e) { PathInfo cellpath = new PathInfo(); //a custom class to hold path info string path = string.Empty; DataGrid dgdataPaths = (DataGrid)sender; int rowcnt = dgdataPaths.SelectedItems.Count; cellpath = (PathInfo)e.Item; path = "Row #"+ clipboardcalledcnt +" Len="+ cellpath.Length.ToString() + ", path=" + cellpath.Path; e.ClipboardRowContent.Clear(); if (clipboardcalledcnt == 0) //add header to clipboard paste e.ClipboardRowContent.Add(new DataGridClipboardCellContent("", null, "--- Clipboard Paste ---\t\t\n")); // \t cell divider, repeat (number of cells - 1) clipboardcalledcnt++; e.ClipboardRowContent.Add(new DataGridClipboardCellContent(path, null, path)); if (clipboardcalledcnt == rowcnt) clipboardcalledcnt = 0; }
