我正在开发一个VB.NET应用程序，它将数据返回给DataGrid。除了一件事，现在一切正常。我希望数据网格下面的所有空白空白都不显示，这样用户就不必担心向下滚动页面了。
目前，它正确显示DataGrid，带有滚动条，此网格占据了我的显示器高度的一半左右。但是在这个网格下面有很多空白空间。我该如何删除？
这是我的ASPX文件的结尾：
<head>
<title></title>
<style type="text/css">
.DataGridFixedHeader {background-color: #336699; color:White; font-weight: "bold"; position:relative; top:expression(this.offsetParent.scrollTop);}
#txtFind{ width:150; padding:5px; outline:none; height:20px; }
.focusField{ border:solid 2px #73A6FF; background:#EFF5FF; color:#000; }
.idleField{ background:#EEE; color: #6F6F6F; border: solid 2px #DFDFDF; }
</style>
</head>
<body>
<form runat="Server" defaultbutton= "btnFind" method="post" id="Form1">
<div style="font-size:18pt; font-family:verdana; font-weight:bold; color:#336699">

<hr style="font-weight: bold; font-size: 20pt; color:#000080;" />

Reliability Rate = 1 - ( number of failed parts in the last 6 months / Part Multiplier * Average instrument Census in the last 6 months),<br />
Where
<br />
Number of failed parts - Summation of failures of a part for a 6 month period<br />
Part Multiplier - Number that represents how many times a part is used on the intrument<br />
Average instrument census - Average of the instrument census for the same
6 month timeframe as failed parts<br />

降低其所在DIV的样式高度（目前设置为400px）。
