推荐答案

你好，



假设我有一个datagridview，有两列。其中一个是DatagridviewCombobox列（位于第0位），另一个是TextBox列（位于第1位）。



现在，如果我想从外面获取这些值如果用户动态地添加行，我必须进行循环。

Hello ,

suppose i have a datagridview , there are two columns . one of them is DatagridviewCombobox column (at 0th position) and another one is TextBox column(at 1st position).

now , if i want to get those value from outside of a button , i have to make loop if user dynamically can add rows .

private void btn_Click(object sender, EventArgs e)
{
  for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
    {
     string cmbvalue = dataGridView1.Rows[i].Cells[0].Value.ToString(); 
     //for combobox column
     string txtvalue = dataGridView1.Rows[i].Cells[1].Value.ToString();
     //for textbox column

     //other codes to save those value in database  

    }
        
}

谢谢

thanks

通过gridview c＃.net
