DataGrid嵌套DataList，如何激活DataList里面的LinkButton控件的事件？

Question

如题，怎么办啊？数据已经绑定好了，但是始终不能触发datalist里面的linkbutton的事件。

Answer 1

例如：
<asp:LinkButton id="lbtnFirst" CssClass="csslink" Text="首页" CommandName="First" runat="server" />

Answer 2

不行的。用了你们说的方法，不行，不能触发linkbutton的事件。后台也写了相应代码，中断跟踪，根本就没有执行到那个地方

Answer 3

前台部分代码：           <div id="div_content" style="overflow: auto; width: 800px; height: 340px">
                                            <asp:DataGrid ID="dtg_Body" runat="server" AutoGenerateColumns="False" ShowHeader="False" EnableViewState ="true" OnItemDataBound="dtg_Body_ItemDataBound">
                                                <SelectedItemStyle CssClass="datagrid_selectedstyle"></SelectedItemStyle>
                                                <ItemStyle CssClass="datagrid_itemstyle" HorizontalAlign="Center"></ItemStyle>
                                                <Columns>                                          
                                                    <asp:TemplateColumn ItemStyle-Height="60px" ItemStyle-HorizontalAlign="center" ItemStyle-VerticalAlign="Top">
                                                        <ItemTemplate>
                                                          <asp:label runat="server" ID="lbl_Date1" Text='<%# DataBinder.Eval(Container, "DataItem.Date1") %>' ></asp:label>
                                                       <div runat="server" id="div21" style="overflow: auto; width: 100%;">
                                                      
                                                        <asp:DataList runat="server" ID="dl_TPTitle1" EnableViewState="true" >
                                                             <ItemTemplate>
                                                              
                                                                <%# DataBinder.Eval(Container, "DataItem.TPDate","{0:h:m}")%>
                                                               <asp:LinkButton runat="server" ID="lbtn_TP" Text='<%# DataBinder.Eval(Container, "DataItem.TPTitle") %>'  CommandName="ViewTP" ></asp:LinkButton>

                                                          <asp:Label runat="server" ID="lbl_Month" Visible="true" Text='<%# DataBinder.Eval(Container, "DataItem.TPID") %>'></asp:Label>
                                                         
                                                        </ItemTemplate>                                        
                                                    </asp:DataList>    
                                                     </div>                     
                                                        </ItemTemplate>
                                                    </asp:TemplateColumn>
                                                   <asp:TemplateColumn ItemStyle-Height="60px" ItemStyle-HorizontalAlign="center" ItemStyle-VerticalAlign="Top">
                                                        <ItemTemplate>
                                                            <asp:label runat="server" ID="lbl_Date2" Text='<%# DataBinder.Eval(Container, "DataItem.Date2") %>' ></asp:label>
                                                            <div runat="server" id="div22" style="overflow: auto; width: 100%;">
                                                        <asp:DataList runat="server" ID="dl_TPTitle2" EnableViewState="False" >
                                                        <ItemTemplate>                                                         
                                                           <%# DataBinder.Eval(Container, "DataItem.TPDate", "{0:h:m}")%>                                                                      
                                                               <asp:LinkButton runat="server" ID="lbtn_TP" Text='<%# DataBinder.Eval(Container, "DataItem.TPTitle") %>'   CommandName="ViewTP" ></asp:LinkButton>

                                                          <asp:Label runat="server" ID="lbl_Month" Visible="false" Text='<%# DataBinder.Eval(Container, "DataItem.TPID") %>'></asp:Label>
                                                        
                                                        </ItemTemplate>

                                                     </div>                
                                                        </ItemTemplate>
                                                    </asp:TemplateColumn>
                      </Columns>
                                            </asp:DataGrid>
                                        </div>

Answer 4

有人说用冒泡事件可以，但是我用ItemCreate冒泡，还是不能触发LinkButton事件

Answer 5

我刚写的，：），楼主看http://blog.csdn.net/sfbasic/archive/2007/04/06/1553922.aspx

Answer 6

看了你的文章，不过不能解决我的问题。嵌套后问题难度不一样了。DataGrid 里面嵌套 DataList， DataList里面的控件触发不了。在DataList外面的都可以触发。搞了三天了，还没有解决郁闷死了哪位高手 帮我啊

Answer 7

在DataList里ItemCreate方法里面.手动注册内部的控件事件.就行了.

Answer 8

试一下：private void dtg_Body_ItemCreated(object sender, DataGridItemEventArgs e)
   {        if (e.Item.ItemType.ToString() == "Item" || e.Item.ItemType.ToString() == "AlternatingItem")
        {            DataList TPTitle1 = (DataList)e.Item.FindControl("TPTitle1");              TPTitle1.ItemCommand += new DataGridCommandEventHandler(TPTitle1_ItemCommand);        }    }
 protected void TPTitle1_ItemCommand(object source, DataGridCommandEventArgs e)
    {//。
    }

Answer 9

楼上的方法和我说的是一样的,但是判断的时候,最好用下的判断
if(e.Item.ItemType ==ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)

Answer 10

哎,我试过好几次了，都不行，用断点跟踪，根本上就不去执行TPTitle1_ItemCommand（）;

Answer 11

TPTitle1.ItemCommand += new DataGridCommandEventHandler(TPTitle1_ItemCommand);这句有没有执行，PostBack 的时候，可能你没有DataBind(), 也就没有执行这行语句。

Answer 12

TPTitle1.ItemCommand += new DataGridCommandEventHandler(TPTitle1_ItemCommand);这句执行了，不执行
protected void TPTitle1_ItemCommand(object source, DataGridCommandEventArgs e)
{}

Answer 13

protected void TPTitle1_ItemCommand(object source, DataGridCommandEventArgs e)
应该为：
protected void TPTitle1_ItemCommand(object source, DataListCommandEventArgs e)

Answer 14

    protected void dtg_Body_ItemCreated(object sender, DataGridItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
        {
              for (int i = 1; i <= 7; i++)
                {
                    DataList dl_TPTitle = new DataList();
                    dl_TPTitle = (DataList)e.Item.FindControl("dl_TPTitle" + i.ToString());
                  dl_TPTitle.ItemCommand += new DataListCommandEventHandler(dl_TPTitle_ItemCommand);ataBound);
                }            
        }
    }注:在前台有7个datalist分别是:dl_TPTitle1 到dl_TPTitle7,所以用一个循环.protected void dl_TPTitle_ItemCommand(object sender, DataListCommandEventArgs e)
    {
        LinkButton lbtn_TP = new LinkButton();
        lbtn_TP = (LinkButton)e.Item.FindControl("lbtn_TP");
        if (e.CommandName == "ViewTP")
        {
            Label label = new Label();
            label = (Label)(e.Item.FindControl("lb_Month"));
            string strTPID = label.Text;
            ShowModalDialog("WeekAndMonthTask_Detail.aspx?TPID=" + strTPID, "280", "600", "btn_MRefresh");
        }
    }
中断跟踪,dl_TPTitle_ItemCommand()就没有执行到.目的是,点击LinkButton里面的内容,弹出新窗口WeekAndMonthTask_Detail.asps谢谢

Answer 15

.....7个绑定到同一个方法上你在PageLoad的时候有没有判断IsPostBack，PostBack的时候也要绑定事件才行从简单的开始调试吧，先试一试一个DataList可不可行
另外DataList dl_TPTitle = new DataList();
dl_TPTitle = (DataList)e.Item.FindControl("dl_TPTitle" + i.ToString());
改成
DataList dl_TPTitle = (DataList)e.Item.FindControl("dl_TPTitle" + i.ToString());
就可以

Answer 16

protected void dtg_Body_ItemCreated(object sender, DataGridItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
        {
              for (int i = 1; i <= 7; i++)
                {
                    DataList dl_TPTitle = new DataList();
                    dl_TPTitle = (DataList)e.Item.FindControl("dl_TPTitle" + i.ToString());
                  dl_TPTitle.ItemCommand += new DataListCommandEventHandler(dl_TPTitle_ItemCommand);
                }            
        }
    }

Answer 17

实话告诉你吧，你用2003嵌套，就是没有事件。
这是.net2003设计时就定了的，貌似没有解决办法。2005好了。
又或者你试试自己做个委托挂接事件。

Answer 18

呵呵,我就是2005.不这样做了，太烦。用javascript算了
