GridView用代码增加的列怎么样才能在页面源代码里看到

[humdark]

GridView所有的列都是通过代码动态增加的，其中有一列是模板列里面是CheckBox，我想用JavaScript控制这些CheckBox，但是发现生成的网页里找不到自动生成GridView。查看网页源文件，发现没有GridView任何html代码。这是什么原因？有没有办法可以让我用JavaScript控制动态生成的CheckBox？

通过代码动态增加,应该是利用DataTable来增加的吧? 先把要绑定的数据放到DataTable中,然后再绑定,这样应该就不会有问题了,table的行和列可以根据要求来添加的

如果你的gridview没有绑定数据的话肯定会看不到。建议不要动态生成，动态生成遇到页面刷新问题就麻烦了

[oec2003]

如果页面上gridview呈现了数据
源文件中就肯定能找到
gridview在客户端生成的是table

可以用js 多那个table来操作 就可以找到

在页面源代码中确实没有gridview的任何代码，下面是代码的一部分，其中两个没内容的div中间应该是gridview
<div id="divRptList" class="DivStyle" style="border-top-style:none;">
<table class="TableStyle" style="width:100%">
<tr>
<td class="TableTitle" id="tdW"><span id="lbW">未收录报表</span></td>
</tr>
<tr>
<td class="TdStyle">
<div>

</div>
</td>
</tr>
<tr>
<td>
<a id="lbSelAll" href="javascript:__doPostBack('lbSelAll','')">全选</a> 
<a id="lbSL" href="javascript:__doPostBack('lbSL','')">收录</a> 

<a id="lbSelAll_C" href="javascript:CheckAll()">全选2</a>
</td>
</tr>
<tr>
<td class="TableTitle" id="tdY"><span id="lbY">已收录报表</span></td>
</tr>
<tr id="trAddSL">
<td class="TdStyle">

</td>
</tr>

<tr>
<td class="TdStyle">
<div>

</div>
</td>
</tr>
</table>
</div>

对应的在vs里面编辑的代码是
<asp:UpdatePanel ID="upRptList" runat="server">
<ContentTemplate>
<div id="divRptList" class="DivStyle" style="border-top-style:none;">
<table class="TableStyle" style="width:100%">
<tr>
<td class="TableTitle" id="tdW"><asp:Label ID="lbW" runat="server" Text="Label"></asp:Label></td>
</tr>
<tr>
<td class="TdStyle">
<asp:GridView ID="gvWsl" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Vertical">

<SelectedRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />

<HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />

</asp:GridView>
</td>
</tr>
<tr>
<td>

<a id="lbSelAll_C" href="javascript:CheckAll()">全选2</a>
</td>
</tr>
<tr>

</tr>
</table>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</td>
</tr>
<tr>
<td class="TdStyle">

这种情况是不是跟我对gridview的某个设置有关？

[阳光彩虹小白马嘀嘀哒嘀嘀嗒]

可以在JS里调用后台方法，控制内容写在后台。

<script language="javascript" type="text/javascript">   
 var s=<% f()%>
</script>

public String f()
{
       if (GridView1.Rows.Count < 1)
        {
            return;
        }

        int mycount = 0;
        foreach (GridViewRow myRow in GridView1.Rows)
        {
            CheckBox CheckBox1 = (CheckBox)myRow.FindControl("CheckBox1");
            if (CheckBox1.Checked == true)
            {
                mycount++;
            }
        }
        if (mycount < 1)
        {
            ScriptManager.RegisterStartupScript(this, this.GetType(), "bt_delete", "alert('请选择要删除的项')", true);
            return;
        }

        foreach (GridViewRow myRow in GridView1.Rows)
        {
            CheckBox CheckBox1 = (CheckBox)myRow.FindControl("CheckBox1");
            if (CheckBox1.Checked == true)
            {
                string _CNid = GridView1.DataKeys[myRow.RowIndex].Value.ToString();
                bll_Order order = new bll_Order();
                order.O_ID =Convert.ToInt32(_CNid);
                bll_Order.Delete(order);
            }
        }
}
