WinForm中如何实现两个DataGridView的数据联动？

Question

我现在又两个datagridview 然后我想要点击第一个datagridview中的一个单元格的数据，把它显示到第二个datagridview中，请高手指教，最好能给我个小例子谢谢

Answer 1

看datagridview 有个选择行事件    点事件   把ID传给第2个datagridview  然后绑定代码有点多，所以你按我这个思路尝试着做做

Answer 2

得到选中行，返回的是一个行的对象，然后把这一行添加到第二个gridview中
dataTable dt=grid.datasorcse as dataTable;
dataRow r=dt.newRow();
r[]=选中行的对象[];
r[]=
...
grid.datasorcse=dt;

Answer 3

跟新第二个DataGridView的数据源
DataBind事件

if (dataGridView2.CurrentRow == null) return;
            DataGridViewRow dgv2 = dataGridView2.CurrentRow;
            if (dataGridView1.CurrentRow == null) return;
            DataGridViewRow dgv = dataGridView1.CurrentRow;
            int rowIndexNew = dgv.Index;
            string dgv2Text = dgv2.Cells[0].Value.ToString().Trim();
           for (int i = 0; i < dataGridView1.RowCount; i++)
           {
               DataGridViewRow dgv1 = dataGridView1.Rows[i];
               int rowIndexOld = dgv1.Index;
               string dgv1Text = dgv1.Cells[0].Value.ToString().Trim();
               if (dgv1Text == dgv2Text)
               {
                   if (rowIndexNew == 0)
                   {
                       dgv1.Cells[1].Value = Convert.ToInt32(dataGridView1.Rows[0].Cells[1].Value) + 10;
                      
                   }
                   else
                   {
                       int scoreUp =Convert.ToInt32(dataGridView1.Rows[rowIndexNew - 1].Cells[1].Value);
                       int scoreDown = Convert.ToInt32(dataGridView1.Rows[rowIndexNew].Cells[1].Value);
                       Convert.ToInt32(dgv1.Cells[1].Value);
                       dgv1.Cells[1].Value = (scoreUp + scoreDown) / 2;
                   }
                   //开始移动数据
                               var tempRow = dt.NewRow();
                               tempRow.ItemArray = dt.Rows[rowIndexOld].ItemArray;
                               dt.Rows.RemoveAt(rowIndexOld);
                               dt.Rows.InsertAt(tempRow, rowIndexNew);
                               for (int k = dataGridView1.Rows.Count - 1; k >= 0; k--)
                               {
                                   dataGridView2.Rows[dataGridView1.Rows.Count - 1-k].Cells[0].Value = dataGridView1.Rows[k].Cells[0].Value;
                                   dataGridView2.Rows[dataGridView1.Rows.Count - 1-k].Cells[1].Value = dataGridView1.Rows[k].Cells[1].Value;
                               }
                                   break;
                                  
                           }
                       }
