如何在按钮单击事件上从 DataGridView 填充文本框

Question

我想从 DataGridView 控件填充按钮单击事件的数据：

我的代码如下

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

循环浏览您的列可能不会有帮助。

尝试为每个文本框分配它映射到的单元格：

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

Answer 2

为什么必须使用循环？只需编写

 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行以更新并编写代码如下

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