DataGridView与TextBox的绑定

1、

private void Query()
        {
            //dgInOut为DataGridView控件
           IList<AccountInfo> accounts = accountBLL.GetList();
            this.dgAccount.DataSource = accounts;

           //如下代码实现，单击网格时，自动将网格中当前行的相应列赋值给日期、文本等控件的相应属性中。
            this.txtCode.DataBindings.Clear();
            this.txtCode.DataBindings.Add("Text", accounts, "Code");

this.rbIn.DataBindings.Clear();
this.rbIn.DataBindings.Add("Tag", accounts, "Direction");

this.txtID.DataBindings.Clear();

this.txtID.DataBindings.Add("Text", accounts, "ID");

            //可添加绑定数据变化时的触发处理
            this.txtName.DataBindings.Clear();
            this.txtName.DataBindings.Add("Text", accounts, "Name").Format += new ConvertEventHandler(Account_Format);
        }

        void Account_Format(object sender, ConvertEventArgs e)
        {
            if (rbIn.Tag.ToString() == "收")
                this.rbIn.Checked = true;
            else
                this.rbOut.Checked = true;
        }

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
Query();

}

次数据绑定要求accounts为全局变量

2、

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)

{

//获取客房类型ＩＤ

if (e.RowIndex >= 0)

{

typeID = dataGridView1.Rows[e.RowIndex].Cells["ID"].Value.ToString();

//调用业务逻辑层通过类型ＩＤ得到客房类型信息

RoomType roomType = manager.GetRoomTypeByTypeID(Convert.ToInt32(typeID));

//回绑数据

this.txtRemark.Text = roomType.Remark;

}
