访问“第"在列表视图中 [英] Access "th" in Listview

问题描述

在后面的代码中是否有访问"th"的方法.我想根据项目值在页眉中添加填充.

Is there a way to access the "th", in the code behind. I would like to add padding to the header depending on the item value.

<LayoutTemplate>
        <table runat="server" >
            <tr runat="server">
                <td runat="server">
                    <table ID="itemPlaceholderContainer" runat="server" border="0" class="UserLayoutTbl">
                        <tr runat="server" style="">
                            <th runat="server" width="140" align="left">
                                Date</th>
                            <th runat="server" width="140" align="left">
                                Ref. No.</th>
                            <th runat="server" width="270" align="left">
                                Description</th>
                           <%-- <th runat="server" width="90" align="right" style = '<%# GetAmountLabelStyle() %>'>
                                Amount</th>--%>
                                <th id="Th1" runat="server" width="90" align="right">
                                Amount</th>
                        </tr>
                        <tr ID="itemPlaceholder" runat="server">
                        </tr>
                    </table>
                </td>
            </tr>

推荐答案

首先，为要更改的元素提供一个ID.在ListView的DataBind之后，您可以使用ListView的FindControl方法通过控件的ID访问该控件.然后，您可以将返回的控件转换为HtmlTableCell以正确处理它:

First, give an ID to the element you want to change. After DataBind of the ListView, you can access the control by its ID using the FindControl method of the ListView. Then, you can convert the returned control to HtmlTableCell to proper handle it:

// thDate is the <th> ID
HtmlTableCell thDate = lstItems.FindControl("thDate") as HtmlTableCell;
