如何在Button Click事件上从DataGridView填充TextBoxes

Question

我想从DataGridView控件填充按钮点击事件的数据：

我的代码就像这样

for (int i = 0; i < dgv_EmpAttList.Columns.Count; i++)
{
  txt_EnrollNo.Text = this.dgv_EmpAttList.CurrentRow.Cells[i].Value.ToString();
  txt_FirstInTime.Text = this.dgv_EmpAttList.CurrentRow.Cells[i].Value.ToString();
  txt_LastOutTime.Text = this.dgv_EmpAttList.CurrentRow.Cells[i].Value.ToString();
  txt_TotalHours.Text = this.dgv_EmpAttList.CurrentRow.Cells[i].Value.ToString();
}

Answer 1

在这里循环可能无济于事。

尝试为每个文本框分配映射到的单元格：

txt_EnrollNo.Text = this.dgv_EmpAttList.CurrentRow.Cells[1].Value.ToString();
txt_FirstInTime.Text = this.dgv_EmpAttList.CurrentRow.Cells[2].Value.ToString();

Answer 2

为什么你必须使用循环？只需你可以写

 txt_EnrollNo.Text = this.dgv_EmpAttList.CurrentRow.Cells[0].Value.ToString(); 
txt_FirstInTime.Text = this.dgv_EmpAttList.CurrentRow.Cells[1].Value.ToString();
txt_LastOutTime.Text = this.dgv_EmpAttList.CurrentRow.Cells[2].Value.ToString();
 txt_TotalHours.Text = this.dgv_EmpAttList.CurrentRow.Cells[3].Value.ToString(); 

编辑：

然后在按钮上单击发送要更新的行并按如下所示编写代码

txt_EnrollNo.Text = row.Cells[0].Value.ToString(); //where row is DataGridViewRow
