aspx DataList控件,获取点击行的ID? [图]

Question

[VS2005 Access数据库 C# .aspx]
图1:数据库
    <asp:DataList ID="DataList1" runat="server" Height="1px" Width="100%" OnItemCommand="DataList1_ItemCommand"
        CellPadding="4" CellSpacing="1" ForeColor="#333333" EnableViewState="False">
        <ItemTemplate>
            <table border="0" width="100%" style="font-size: 14px;">
                <tr>
                    <td align="left">
                        <asp:LinkButton ID="linkNumber" runat="server" CommandName="SelectInfo" ForeColor="black">
                                                <%# DataBinder.Eval(Container.DataItem, "Title")%>
                        </asp:LinkButton>
                    </td>
                    <td style="width: 100">
                        <%# DataBinder.Eval(Container.DataItem, "RDate","{0:yyyy-MM-dd}")%>
                    </td>
                </tr>
            </table>
        </ItemTemplate>
        <HeaderStyle HorizontalAlign="Center" BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
        <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
        <AlternatingItemStyle BackColor="White" />
        <ItemStyle BackColor="#EFF3FB" />
        <SelectedItemStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
    </asp:DataList>    protected void Page_Load(object sender, EventArgs e)
    {
        DataList1.DataSource = clsSql.GetDs("select ID,Title,RDate from 表 Order By ID desc ", "表");
        DataList1.DataBind();
    }    //查看详细新闻
    protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandName == "SelectInfo")
        {
            //点击新闻标题后,如何得到ID ?
        }
    }
图2:目前效果图
图1是数据库字段,ID是string类型的;
不清楚我意思,请回帖;

Answer 1

e.CommandArgument
<asp:Button ID="Button1" runat="server" OnClick="btn_Click" CommandArgument='<%#DataBinder.Eval(Container.DataItem, "id" )%>' Text="Button" />
这是一个办法。

Answer 2

 //                                                                选中行显示整条数据
        private void dataGridView1_MouseClick(object sender, MouseEventArgs e)
        {
            //获取行的name值，用来调用ID
            string name = this.dataGridView1.CurrentRow.Cells[1].Value.ToString();
            this.BindDataByName("IDNO", name);
        }

Answer 3

 for (int i = 0; i < dataGridView1.Rows.Count; i++)
                    {
                        if (dataGridView1.Rows[i].Selected == true)
                        {
                            string name = this.dataGridView1.Rows[i].Cells[1].Value.ToString();//身份证号
                            string delete = "delete from StuTable where  [IDNO]='" + name + "'";
                            constring(delete);
                        }
                    }

Answer 4

增加一个id的隐藏列  用click事件去取相应的cell

Answer 5

<tr id = "trContent" onclick = "GetId(this);">
<td align="left">
    <asp:TextBox ID = "txtId" ruant = "server" text = " <%# DataBinder.Eval(Container.DataItem, "ID")%>
"
    <asp:LinkButton ID="linkNumber" runat="server" CommandName="SelectInfo" ForeColor="black">
    <%# DataBinder.Eval(Container.DataItem, "Title")%></asp:LinkButton>
</td>
<td style="width: 100">
     <%# DataBinder.Eval(Container.DataItem, "RDate","{0:yyyy-MM-dd}")%>
</td>
</tr>通过上面的方法可以得到选中的<tr>的ID那么在JS事件GetID里面就能根据这个ID去推断出新填加进去的textBox的ID,然后就能拿到你想要的值了像DataList GridView等生成的源码的ID都是有规律的,我拿一个我自己写的简单JS给你看看吧

Answer 6

function IsChecked(cb)
{
    var count = document.getElementById("hfCount").value;
    for(i = 2;i<count + 1;i++)
    {
        var cbo;
        if(i<10)
        {
            cbo = document.getElementById("gvArea_ctl0"+i+"_cboIndex");
        }   
        else
        {
            cbo = document.getElementById("gvArea_ctl"+i+"_cboIndex");    
        }
        
        if(cbo != cb)
        {
            cbo.checked = false;
        }
        else
        {
            cbo.checked = true;
        }
    }
}规律怎么看出来的?  打开你的网页后,右键  查看源码,下面是我的程序的某页面的部分源码:<table class="repeater " cellspacing="0" rules="all" border="1" id="gvAddCustomer" style="font-size:12px;width:900px;border-collapse:collapse;">

</table>怎么样?看出点规律来了???

Answer 7

回复1楼:我不行ID显示出来回复2楼:我的是DataList控件回复4楼:如何隐藏,如何获取?回复5楼,没看出什么规律来,我重没见过这样用JS的
