blocks|key|1684580|text|答案中的代码需要在Page_Load或GridView_PreRender上运行。我把它放在一个在Page_Load之后调用的方法中，并得到了一个NullReferenceException。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1684581|entityMap^0|9|9|J|I|1D|9|21|M|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|G|$]]

<p>The code in the answer needs to go on <code>Page_Load</code> or <code>GridView_PreRender</code>. I put it in a method that was called after <code>Page_Load</code> and got a <code>NullReferenceException</code>.</p>

<p>I know this is old, but, here's an interpretation of MikeTeeVee's answer, for a standard gridview:</p>

<p>aspx page:</p>

<pre><code>&lt;asp:GridView ID="GridView1" runat="server" 
    OnPreRender="GridView_PreRender"&gt;
</code></pre>

<p>aspx.cs:</p>

<pre><code>    protected void GridView_PreRender(object sender, EventArgs e)
    {
        GridView gv = (GridView)sender;

        if ((gv.ShowHeader == true &amp;&amp; gv.Rows.Count &gt; 0)
            || (gv.ShowHeaderWhenEmpty == true))
        {
            //Force GridView to use &lt;thead&gt; instead of &lt;tbody&gt; - 11/03/2013 - MCR.
            gv.HeaderRow.TableSection = TableRowSection.TableHeader;
        }
        if (gv.ShowFooter == true &amp;&amp; gv.Rows.Count &gt; 0)
        {
            //Force GridView to use &lt;tfoot&gt; instead of &lt;tbody&gt; - 11/03/2013 - MCR.
            gv.FooterRow.TableSection = TableRowSection.TableFooter;
        }

    }
</code></pre>


blocks|key|1469359|text|创建一个函数并在PageLoad事件中使用该函数，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1469360|该函数为：|1469361|private+void+MakeGridViewPrinterFriendly(GridView+gridView)+{++

++++++++gridView.UseAccessibleHeader+=+true;++
++++++++gridView.HeaderRow.TableSection+=+TableRowSection.TableHeader;++
++++}++
}+|code-block|syntax|javascript|1469362|PageLoad事件是：|1469363|protected+void+Page_Load(object+sender,+EventArgs+e)+{
++++++++if+(!IsPostBack)
++++++++{

}|1469364|entityMap^0|8|8|0|0|0|0|8|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|V|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|W|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|X|8|@$9|Y|A|Z|B|C]]|D|@]|E|$]]|$1|O|3|P|5|J|7|10|8|@]|D|@]|E|$K|L]]|$1|Q|3|-4|5|6|7|11|8|@]|D|@]|E|$]]]|R|$]]

<p>Create a function and use that function in your <code>PageLoad</code> event like this:</p>

<p>The function is:</p>

<pre><code>private void MakeGridViewPrinterFriendly(GridView gridView) {  
    if (gridView.Rows.Count &gt; 0) {          
        gridView.UseAccessibleHeader = true;  
        gridView.HeaderRow.TableSection = TableRowSection.TableHeader;  
    }  
} 
</code></pre>

<p>The <code>PageLoad</code> event is:</p>

<pre><code>protected void Page_Load(object sender, EventArgs e) {
        if (!IsPostBack)
        {
            MakeGridViewPrinterFriendly(grddata);
        }
}
</code></pre>


blocks|key|1469603|text|您也可以使用jQuery添加它。这避免了在PostBack上丢弃TableRowSection.TableHeader时出现的问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1469604|$('#myTableId').prepend($("<thead></thead>").append($(this).find("#myTableId+tr:first")));|offset|length|style|CODE|1469605|entityMap^0|0|0|2I|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

<p>You can also use jQuery to add it.  This avoids the problem with TableRowSection.TableHeader where  gets dropped on PostBack.</p>

<p><code>$('#myTableId').prepend($("&lt;thead&gt;&lt;/thead&gt;").append($(this).find("#myTableId tr:first")));</code></p>


<p>How do I get the <code>GridView</code> control to render the <code>&lt;thead&gt;</code> <code>&lt;tbody&gt;</code> tags? I know <code>.UseAccessibleHeaders</code> makes it put <code>&lt;th&gt;</code> instead of <code>&lt;td&gt;</code>, but I cant get the <code>&lt;thead&gt;</code> to appear.</p>


How do I get Gridview to render THEAD?

如何让GridView控件呈现<thead> <tbody>标记？我知道.UseAccessibleHeaders让它放入<th>而不是<td>，但是我不能让<thead>出现。
