将当前的DataRowView更改为特定的DataRowView

Question

我想将当前的DataRowView更改为一个特定的行，这样我就可以在我想要的地方设置值。

public void SetTimeFromTimer(DateTime date, string timeFromTimer)
{
     monthCalendar1.SetDate(date);
     dataGridView1.ClearSelection();
     dataGridView1.Rows[1].Selected = true;
     DataRowView rowView = (DataRowView)BindingContext[repTimeTable].Current;
     rowView["zr"] = timeFromTimer;
}

Answer 1

public void SetTimeFromTimer(DateTime date, string timeFromTimer)
{
  monthCalendar1.SetDate(date);
  dataGridView1.ClearSelection();
  int rowIndex = repTimeTable.Rows.IndexOf(repTimeTable.Select($"zraufnr = '{GetProjectNumber}' AND zrpnr = '{GetPersonalNumber}'")[0]);
  if (!string.IsNullOrEmpty(rowIndex.ToString()))
  {
    dataGridView1.CurrentCell = dataGridView1.Rows[rowIndex].Cells[ColumnZrZeit.Index];
    DataRowView rowView = (DataRowView) BindingContext[repTimeTable].Current;
    rowView["zr"] = timeFromTimer;
  }
}

您必须循环遍历每一列，并将当前单元格的值分配给所需行的单元格。下面的代码可以帮助您。

public void ChangeRowValues(int parentRow, int rowToBeChanged)
    {
        for (int i = 0; i < dataGridView.Columns.Count; i++)
        {
            dataGridView.Rows[rowToBeChanged].Cells[i].Value = 
            dataGridView.Rows[parentRow].Cells[i].Value;
        }
    }
