推荐答案

绑定数据后调用下面的函数使空单元格为0

After binding the data call the below function to make the empty cells as 0

private void MakeZeroForEmptyCells()
       {
           foreach (DataGridViewRow row in dataGridView1.Rows)
           {
               foreach (DataGridViewCell cell in row.Cells)
               {
                   string value = Convert.ToString(cell.Value);
                   cell.Value = string.IsNullOrWhiteSpace(value) ? 0 : cell.Value;
               }

           }
       }

你应该打电话给这个函数 CellValueChanged 在单元格填充空值时更新数据。

and you shall call this function on CellValueChanged to update the data when the cell is filled with empty value.
