推荐答案

您好，



尝试使用RowDataBound事件。使用以下代码：

Hi,

Try using the RowDataBound Event. Use the following code:

protected void gridview_RowDataBound(object sender, GridViewRowEventArgs e)
{   
   //Get data row view
   DataRowView drview = e.Row.DataItem as DataRowView;
   if (e.Row.RowType == DataControlRowType.DataRow)
   {
      int value1 = Int32.Parse(e.Row.Cells[0].Text);
      int value2 = Int32.Parse(e.Row.Cells[1].Text);
      e.Row.Cells[2].Text = Convert.ToString(value1+ value2);
   }
}

希望这会有所帮助并给你一个想法:)

in DataGridView.CellEndEdit Event [ ^ ]计算并设置totalstack单元格值。 />
示例代码：

in DataGridView.CellEndEdit Event[^] calculate and set the totalstack cell value.
Sample code:

int val1 = Convert.ToInt32(dataGridView1.Rows[e.RowIndex].Cells[0].Value);
int val2 = Convert.ToInt32(dataGridView1.Rows[e.RowIndex].Cells[1].Value);
dataGridView1.Rows[e.RowIndex].Cells[2].Value = (val1 + val2).ToString();
