我在datagridview中添加了更新按鈕，當在C＃中單擊按鈕時，如何更改文本？

Question

我正在用C＃開發Windows應用程序。 我使用以下代碼在datagridview內創建了一個按鈕

  DataGridViewButtonColumn btn = new DataGridViewButtonColumn();
  dataGridViewTrial.Columns.Add(btn);
  btn.HeaderText = "Update";
  btn.Name = "btn";
  btn.Text = "Update";
  btn.UseColumnTextForButtonValue = true;

現在我想在單擊更新按鈕時將btn的文本更改為“保存”。我也想更新我的表。我沒有得到它。請幫助我：(

如果我沒記錯，您應該這樣做

    //Here you add event to button
    void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {
        if (e.Control is Button)
        {
            Button btn = e.Control as Button;
            btn.Click -= new EventHandler(btn_Click);
            btn.Click += new EventHandler(btn_Click);
        }
    }

    void btn_Click(object sender, EventArgs e)
    {
        if(sender is button)
            ((button)sender).Text = "new text";
    }

我希望這個幫助

void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
            {
                if (e.Control is Button)
                {
                    Button btn = e.Control as Button;

                    // hook or unhook click event here
                }
            }
