问题描述
嗨
i在asp.net网络应用程序中开发了一个图表作为用户控件
这个图表我想在我的网页中使用应用程序在defalut.aspx页面中我希望这个图表在中心和这个图表代码我想指定一个特定的asp.net控件如何首先做中心位置？
以后如何分配给1个asp.net控制。？
我的用户控件（.ascx.cs）代码：

my user control(.ascx.cs) code:
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
Bitmap objBitmap;
Graphics objGraphics;
objBitmap = new Bitmap(1000, 1000);
objGraphics = Graphics.FromImage(objBitmap);
objGraphics.Clear(Color.White);
Pen p = new Pen(Color.Red, 0);
Rectangle rect = new Rectangle(10, 10, 280, 280);
objGraphics.DrawRectangle(p, rect);
objGraphics.DrawEllipse(p, rect);
objGraphics.DrawLine(p, 500, 60, 480, 60);
Brush b1 = new SolidBrush(Color.Red);
Brush b2 = new SolidBrush(Color.Green);
Brush b3 = new SolidBrush(Color.Blue);
objGraphics.FillPie(b1, rect, 0f, 60f);
//objGraphics.FillPie(b2, rect, 60f, 150f);
//objGraphics.FillPie(b3, rect, 210f, 150f);
FontFamily fontfml = new FontFamily(GenericFontFamilies.Serif);
Font font = new Font(fontfml, 16);
SolidBrush brush = new SolidBrush(Color.Blue);
objGraphics.DrawString("Drawing Graphics", font, brush, 70, 300);
//objGraphics.DrawImage(objBitmap, 300, 300, 400, 500);
//objGraphics.ScaleTransform((float)0.714, (float)0.714);
//objGraphics.DrawImage(objBitmap, 300, 300, 400, 500);
objBitmap.Save(Response.OutputStream, ImageFormat.Gif);
objBitmap.Save(Server.MapPath("x.jpg"), ImageFormat.Jpeg);
objBitmap.Dispose();
objGraphics.Dispose();
}
}

推荐答案
您好，
您可以将align属性用于html中的任何控件：
就像你可以对齐
Hi,
You can use the align property to any of the control in html :
like u can apply align to
<div align="Center"></div>
或表格
or for table
<table align="center">.........</table>
试试这个中心html标签
Try this center html tag
<center>
<table align="Center">
<tr>
<td align="Center">
<asp:MultiView ID="MultiView1" runat="server">
<asp:View ID="View1" runat="server">
<uc1:Graph ID="Graph1" runat="server" />
</asp:View>
</asp:MultiView>
</td>
<td>
</td>
</tr>
<tr>
<td class="style2">
</td>
<td style="">
</td>
</tr>
</table>
</center>
这不是这样的模拟游戏乍一看似乎很有风格的功能。只是中心不能正常工作，因为它也会使它们成为内在的HTML。您需要仅以顶部元素为中心的样式，并根据其自己的样式保持其内部HTML对齐。
请查看我准备的完整样本：
This is not such a simple style feature as it may seem at first glance. Just "center" won''t work properly, because it will also center they inner HTML. You need the style centering only the top element, and leave its inner HTML aligned according its own styles.
Please look at my complete sample I prepared:
<html >
<head>
<title>???</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style type="text/css"><!--
.center {
margin-top:10px;
margin-left:auto;
margin-right:auto;
text-align:center;
border:solid 1px black;
width:828px;
height:20px;}
--></style>
</head>
<body>
<div class="center">It will work for any inner HTML you want to place here...</div>
</body>
</html>
这只是给你一个想法。这里的关键是使用自动边距。现在，如果您将任何内部HTML放在此示例中显示的div中，它将保留自己的样式，包括布局。
请尝试查看。
