Question

I am using a WPF DataGrid to display name-value pairs. SelectionUnit is set to FullRow because it looks nice, however, when user selects a row and presses Ctrl+C he really wants to copy the value text rather than the default behavior which is a concatenation of name and value. When looking for solution I found CopyingRowClipboardContent event but the MSDN page has no information about how to use it. Or should I capture PreviewKeyDown myself?

Answer 1

You can modify the copied data in the CopyingRowClipboardContent event handler using the DataGridRowClipboardEventArgs.

Decompiled source code

public class DataGridRowClipboardEventArgs 
{
    /// <summary>
    /// This list should be used to modify, add or remove a cell
    /// content before it gets stored into the clipboard.
    /// </summary> 
    public List<DataGridClipboardCellContent> ClipboardRowContent
    { 
       ...

So for example, if you have two columns and you only want the first, you can remove the second item like this:

private void grid_CopyingRowClipboardContent(
    object sender, DataGridRowClipboardEventArgs e)
{
    e.ClipboardRowContent.RemoveAt(1);
}
