解决方案
ContentPlaceHolder将始终调整大小以适应其周围和内部的其他元素。那是因为ContentPlaceHolder不是可视控件;也就是说，它不会在最终的HTML中产生任何标记。它只是添加其他内容的标记区域。
如果你想用固定大小构建东西，给它周围和内部的元素提供（CSS）尺寸。占位符。

<asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<form id="form1" runat="server">
<table width="100%" style="height: 100px">
<tr>

</asp:TemplateField>
</Columns>
</asp:GridView>
</form>
</asp:Content> 解决方案
The ContentPlaceHolder will always "resize" to accommodate for other elements around and within it. That's because the ContentPlaceHolder is not a visual control; that is, it doesn't produce any markup in the final HTML. It's just a marker region to add other content to.
If you want to build things at a fixed size, give (CSS) dimensions to the elements around and within the placeholder.
