对DATAGRIDVIEW重写问题

Question

我现在想对DATAGRIDVIEW，如果DATAGRIDVIEW的某一列为日期类型，那么当双击时弹出datetimePiker控件,现在问题是，如何知道双击单元格所属的那一列是否为日期类型？

Answer 1

列上有个属性，记不清了 ，应该是DataType

Answer 2

         private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
         {
             if (dataGridView1.Columns[e.ColumnIndex].ValueType == typeof(DateTime))
             {
                 //...
             }             //if (dataGridView1[e.ColumnIndex, e.RowIndex].ValueType == typeof(DateTime))
             //{
             //    //...
             //}
         }

Answer 3

DateTimePicker dp = new DateTimePicker();  
dataGridView1.Controls.Add(dp);   
private void dataGridView1_CellEnter(object sender, DataGridViewCellEventArgs e)
{
  if (dataGridView1.Columns[e.ColumnIndex].DataPropertyName == "")
  {
}
}
