数据网格更新命令 [英] update command of datagrid

问题描述

嗨.. !!!
更新方法不起作用.当我单击编辑"时，它将允许编辑该特定行，但是当我更改值并单击更新"时，该行不会受到影响

我尝试了很多但没有找到答案

代码如下
受保护的void Gdordermgmt_updatecmd(对象发送者，DataGridCommandEventArgs e)
{
TextBox txtamtrecieved =(TextBox)e.Item.FindControl("txtamtrecieved");
TextBox txtrevisedqtamt =(TextBox)e.Item.FindControl("txtrevisedqtamt");
TextBox tx = new TextBox();
tx =(TextBox)e.Item.Cells [8] .Controls [0];
//cmd.CommandType = CommandType.Text;
cmd.CommandText =更新tbl_mst_Order" +
设置Revised_Quote_Amount =""+ txtrevisedqtamt.Text +"，Received_Amount =""+ txtamtrecieved.Text +"''其中Order_ID =" + e.Item.ItemIndex +";
cmd.Parameters.Add(新SqlParameter("@ txtrevisedqtamt"，SqlDbType.Text));
cmd.Parameters ["@ txtrevisedqtamt"].Value = tx.Text;
cmd.ExecuteNonQuery();
Gdordermgmt.EditItemIndex = -1;
Gdordermgmt.DataBind();
}

推荐答案

您是否将Gdordermgmt_updatecmd事件与页面绑定了?
可能会丢失，并且AutoEventWireUp 不会设置为true.

看看这些工作示例:

在Asp.Net GridView控件中简单地插入，选择，编辑，更新和删除 [

Did you bind the Gdordermgmt_updatecmd event with the page?
Might be missed and AutoEventWireUp not set to true.
