Hi,
The default implelmentation of DataGridView.GetClipboardContent does not
call DataGridViewCell.ParseFormattedValue. Does anyone know how to force
it do this, or how to implement GetClipboardContent so that it does. I
am not clear on how, exactly to build a DataObject to put on the Clipboard.

Thanks

For anyone interested, this is my solution. Warning: this code has not
been thoroughly tested, but the general idea is there:

public override DataObject GetClipboardContent()
{
DataObject data = new DataObject();

if (this.SelectedCells.Count == 0) return data;

Dictionary<int, Dictionary<int, string>> tabs = new Dictionary<int,
Dictionary<int, string>>();
Dictionary<int, Dictionary<int, string>> csvs = new Dictionary<int,
Dictionary<int, string>>();
Dictionary<int, string> rt, rc;
StringBuilder tab = new StringBuilder();
StringBuilder csv = new StringBuilder();
foreach (DataGridViewCell cell in this.SelectedCells)
{
if (!tabs.TryGetValue(cell.RowIndex, out rt))
{
rt = new Dictionary<int, string>();
tabs.Add(cell.RowIndex, rt);
rc = new Dictionary<int, string>();
csvs.Add(cell.RowIndex, rc);
}
else
rc = csvs[cell.RowIndex];

rt.Add(cell.ColumnIndex, cell.Value.ToString());
rc.Add(cell.ColumnIndex, cell.Value.ToString());
}

List<int> cols = new List<int>();
List<int> rows = new List<int>();
foreach (int i in tabs.Keys)
rows.Add(i);
rows.Sort();

string s;
foreach (int i in rows)
{
cols.Clear();
foreach (int k in tabs[i].Keys)
cols.Add(k);
cols.Sort();

foreach (int k in cols)
{
tab.AppendFormat("{0}\t", tabs[i][k]);
csv.AppendFormat("{0},", tabs[i][k]);
}

tab.Remove(tab.Length - 1, 1);
tab.AppendLine();
csv.Remove(csv.Length - 1, 1);
csv.AppendLine();
}

data.SetData(DataFormats.CommaSeparatedValue, csv.ToString());
data.SetData(DataFormats.UnicodeText, tab.ToString());
data.SetData(DataFormats.Text, Encoding.ASCII.GetBytes(tab.ToString()));

DataObject html = base.GetClipboardContent();
data.SetData(DataFormats.Html, html.GetData(DataFormats.Html));

return data;
}
