如何让DataGrid能够在客户端点击某一行的任意位置，而触发服务端的事件(Asp.net)

如何让DataGrid能够在客户端点击某一行的任意位置，而触发服务端的事件(Asp.net)

如下是我的测试（实现了，但存在问题）
1. 在Page_Load中增加代码：
this.Page.GetPostBackEventReference(DataGrid1,"");

2. 在 ItemCreated 事件中编写如下代码(经过观察DataGrid 的 Select LinkButton得到)：
private void DataGrid1_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
  if(e.Item.ItemType==ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem || e.Item.ItemType==ListItemType.SelectedItem)
  {
    e.Item.Attributes.Add("onclick","__doPostBack('"+sender.ClientID+"$_ctl"+(e.Item.ItemIndex+2).ToString()+"$_ctl0','')");
  }
}

与 DataGrid 的 Select LinkButton 的脚本命令一致，但没有触发SelectedIndexChanged事件

3. 加入一个Select LinkButton，再次执行，发现点击某一行的任意位置都可以触发到事件了，虽然得到了想要的结果，但又不希望Select LinkButton出现。

为什么代码一致的情况下，不会在服务端触发事件?

23 个解决方案

#1

你可在行中,加入一个看不见的按钮.然后,对行做事件,当单击行时,用脚本单击按钮.这样就可以实现页面提交.
假设你的按钮放在第0列中(你可用模板列)

1.绑定你的控件
this.datagrid1.DataBind();
2.循环你的控件行(假设你已经添加了一个按钮button1
for(int i=0;i<this.datagrid1.Items.Count;i++)
{
//求取按钮,主要要求取它的ID值
Button mybut = (Button)this.datagrid1.Items[i].FindControl("button1");
//将该按钮隐藏
mybut.Style.Add("display","none");
//对控件的行做事件
this.datagrid1.Items[i].Attributes.Add("onclick","document.all('" + mybut.ClientID + "').click();");
}

这样,当你点击行时,则脚本自动触发点击该行的按钮,从而就实现了页面的提交

#2

这样做，在grid的ItemDataBound事件中写
private void grdOD_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
e.Item.Attributes.Add("onmouseover","currentcolor=this.style.backgroundColor;this.style.backgroundColor='#319de5'");//改变当前行的颜色
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=currentcolor");//恢复当前行的颜色
e.Item.Attributes.Add("OnClick","openShowform(" + "'"+e.Item.Cells[1].Text.ToString() +"','"+Server.UrlEncode(e.Item.Cells[4].Text)+"')");//点击该行的任一位置，触发onclick(写在前台的javascript我这里是打开一个窗口并传值)事件
//
}

成功后，给分啊

考过去可以直接运行,你试试吧..csdn 前一位高手写的.....

上面的各位，请看明白我的问题：
1. 我已经能够在DataGrid中显示 Access/SQL Server/Oracle/MySql任意数据库中所需要的数据，不需要有人告诉我如何做DataBind的工作

2. 我已经能够点击某一行的任意位置都可以触发到事件，但前提是我必须手动加入一个Select LinkButton列，这是我不愿意做的。

上面的所有人都没有回答到关键点上。

我真正想问的是：为什么相同的客户端代码，在服务端不能得到相同的结果？

*本问题与制作服务件控件有点关系，即事件的触发机制，它与客户端的代码的关系。

#10

大家可以参看3个例子：

1. 直接生成脚本(没有Select LinkButton)
Http://HHYD.oicp.net:8081/Test/WebForm3.aspx

2. 直接生成脚本，并且有Select LinkButton
Http://HHYD.oicp.net:8081/Test/WebForm4.aspx

3. 直接生成脚本，并且有Select LinkButton，但将 Select LinkButton 隐藏(与 1 进行比较)
Http://HHYD.oicp.net:8081/Test/WebForm5.aspx

#11

http://www.cnblogs.com/lovecherry/archive/2005/05/15/155831.html

#12

在客户端用javascript 提交到服务器

document.Form.submit()

#13

to LoveCherry(论成败，人生豪迈；大不了，重头再来！^_^) :
那上面仅仅有代码，没有说明。而且代码和我的很接近，没有参考价值。

to goody9807()：
请注意，我生成的脚本中调用了 __doPostBack，它里面已经有 theform.submit();

#14

楼主你有没有仔细看我的代码？麻烦你在再一下
这样做，在grid的ItemDataBound事件中写
private void grdOD_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
e.Item.Attributes.Add("onmouseover","currentcolor=this.style.backgroundColor;this.style.backgroundColor='#319de5'");//改变当前行的颜色
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=currentcolor");//恢复当前行的颜色
e.Item.Attributes.Add("OnClick","openShowform(" + "'"+e.Item.Cells[1].Text.ToString() +"','"+Server.UrlEncode(e.Item.Cells[4].Text)+"')");//点击该行的任一位置，触发onclick(写在前台的javascript我这里是打开一个窗口并传值)事件
//
}

#15

to codeangel(-- 与人方便,自已方便 --) :
麻烦你也看看我的代码：

if(e.Item.ItemType==ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem || e.Item.ItemType==ListItemType.SelectedItem)
  {
    e.Item.Attributes.Add("onclick","__doPostBack('"+sender.ClientID+"$_ctl"+(e.Item.ItemIndex+2).ToString()+"$_ctl0','')");
  }

和你的类似，点击某一行，就会触发__doPostBack方法，将数据提交到服务端

#16

先来接点分啊.

#17

to all:
请看 Http://HHYD.oicp.net:8081/Test/WebForm5.aspx 例子
它已经实现了我需要的功能，但是我必须手动增加一个Select LinkButton到 DataGrid中。

我希望能够不用增加Select LinkButton!

1. 直接生成脚本(没有Select LinkButton)
Http://HHYD.oicp.net:8081/Test/WebForm3.aspx

2. 直接生成脚本，并且有Select LinkButton
Http://HHYD.oicp.net:8081/Test/WebForm4.aspx

3. 直接生成脚本，并且有Select LinkButton，但将 Select LinkButton 隐藏(与 1 进行比较)
Http://HHYD.oicp.net:8081/Test/WebForm5.aspx

这3个例子是我逐步探索这个问题做的页面。它们都使用了我在最上面的代码，区别就在于是否有 Select LinkButton在DataGrid中，和Select LinkButton是否隐藏状态。

#18

都出来了，你还有什么问题?
1.可以将select linkbutton在datagrid中隐藏
2.可以隐藏一个(web或html)控件,在你的“__doPostBack”事件中将你选中的项的ID给这个隐藏控件。
当然你也可再加一个服务器控件的button
如：__doPostBack
function __doPostBack(PersonNO)
if(confirm('你确定要删除该人员吗？'))
{
document.all.txtPersonNo.value = PersonNO;//txtPersonNo是隐藏的
document.all.btnDelPerson.click();//btnDelPerson也是隐藏的因为是它服务器控件所以你可以在他的里面写东西
}
3.用DataGrid的Item.CommandName的也可以操作

#19

你光做一个客户端的服务器提交命令,但这些事件并没有在服务端注册,你在何处接收呢?
另外,也不用太拘泥吧.用我写的方法,可以很好的实现你的目的,并且没有不方便之处,为什么不尝试一下呢?

1. 在Page的类定义增加IPostBackEventHandler接口，例如：
public class MyPage : Page, IPostBackEventHandler

2. 在 ItemDataBound 事件中编写如下代码：
private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
  if(e.Item.ItemType==ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem || e.Item.ItemType==ListItemType.SelectedItem)
  {
    e.Item.Attributes.Add("onclick",
      this.Page.GetPostBackEventReference(this,e.Item.ItemIndex));
  }
}

3. 加入一个事件处理程序。
void IPostBackEventHandler.RaisePostBackEvent(string eventArgument)
{
  int Index=Convert.ToInt16(eventArgument);
  this.SelectedIndex=Index;
  this.OnSelectedIndexChanged(EventArgs.Empty);
}

煞费苦心地去猜测“sender.ClientID+"$_ctl"+(e.Item.ItemIndex+2).ToString()+"$_ctl0”未必是好事，这个结果只是恰好可以，但是你动一动DataGrid的不同Item的设置，就不行了。

用体系结构中已经设计好的方法，其实更简单可靠。
