try { DataGridViewRow selectedRow; /* Find first selected cell's row (or first selected row). */ if (dataGridView1.SelectedRows.Count > 0) selectedRow = dataGridView1.SelectedRows[0]; else if (dataGridView1.SelectedCells.Count > 0) selectedRow = dataGridView1.SelectedCells[0].OwningRow; else return; /* Get clipboard Text */ string clipText = Clipboard.GetText(); /* Get Rows ( newline delimited ) */ string[] rowLines = Regex.Split(clipText, "\r\n"); foreach (string row in rowLines) { /* Get Cell contents ( tab delimited ) */ string[] cells = Regex.Split(row, "\t"); DataGridViewRow r = new DataGridViewRow(); foreach (string sc in cells) { DataGridViewTextBoxCell c = new DataGridViewTextBoxCell(); c.Value = sc; r.Cells.Add(c); } dataGridView1.Rows.Insert(selectedRow.Index, r); } } catch (System.ArgumentException ex) { } catch (Exception ex) { MessageBox.Show(ex.Message); } |
