使用 CSS id 选择器来设置 Gridview 控件的样式

Question

I have an existing CSS file with these 2 id selectors:

#TableHead {
font-family: Arial, Helvetica, sans-serif;
font-size:11px;
font-weight: bold;
color: #000000;
border-top-width: thin;
border-top-style: solid;
border-top-color: #A9AAAA;
border-bottom-width: thin;
border-bottom-style: solid;
border-bottom-color: #A9AAAA;
}

#TableDivs {
border-bottom-width: 1px;
font-size:11px;
border-bottom-style: dotted;
font-family:Arial, Helvetica, sans-serif;
border-bottom-color: #A9AAAA;
}

I need to use "TableHead" to style Gridview header and "TableDivs" to style the rest of the Gridview control. I am able to use TableDivs by enclosing the gridview in section. How can I use TableHead to style the header? Where should I specify id="TableHead"?

The rendered source code of Gridview after adding is:

<div id="TableDivs">
  <div>
    <table cellspacing="0" rules="all" border="0" id="ctl00_Main_GridView1" style="border-width:0px;font-weight:normal;border-collapse:collapse;">
      <tr>
      <th align="left" scope="col">
          <a href="javascript:__doPostBack('ctl00$Main$GridView1','Sort$FileName')">File Name</a>
        </th>
        <th align="left" scope="col"><a href="javascript:__doPostBack('ctl00$Main$GridView1','Sort$Description')">Description</a>
        </th>
        <th align="left" scope="col"><a href="javascript:__doPostBack('ctl00$Main$GridView1','Sort$GroupName')">Folder Name</a>
        </th>
        <th align="left" scope="col">
          <a href="javascript:__doPostBack('ctl00$Main$GridView1','Sort$TimeAdded')">Date Added</a>
        </th>
    </tr>
      <tr>
      <td style="width:30%;">
          <a id="ctl00_Main_GridView1_ctl02_btnDownload" href="javascript:__doPostBack('ctl00$Main$GridView1$ctl02$btnDownload','')">2.txt</a>
        </td>
        <td style="width:40%;">222222</td><td style="width:25%;">group11</td>
        <td style="width:5%;">
          <span id="ctl00_Main_GridView1_ctl02_lblDateAdded"></span>
        </td>
    </tr>
      <tr>
      ...
    </tr>
    </table>
  </div>
</div>

Answer 1

<asp:GridView HeaderStyle-CssClass="your_class" ></asp:GridView>

Answer 2

You should ideally use

Gridview .table, Gridview .th, Gridview .tr, Gridview .tr

selectors. This will help you select the gridview or all similar gridviews and give them a common look and feel.

It also allows CSS to do the styling instead of writing code in .NET and specifying the class.

Answer 3

<asp:GridView ID="gridId" runat="server" >
    <HeaderStyle CssClass="TableHead" />
    <RowStyle CssClass="TableDivs" />
</asp:GridView>

Answer 4

<asp:GridView ID="TableDivs" runat="server" >
    use some js to get the parent of ths or just thead(if GridView can export thead), then add #TableHead to the element.
</asp:GridView>

Thanks everyone for the help. Finally I had no choice but to modify all the css files and add new class selectors, because I had no way of using the id selectors. I used the new class selectors in GridView's HeaderStyle, RowStyle, PagerStyle cssclass attribute. It is working fine now.
