使用Gridview绑定数据库中的图片
注：此系列记录在我实际开发中遇到的问题和收藏一些技巧文章。
我们都知道，在Gridview中不能直接去绑定数据库中的图片，我们可以利用HttpHandler很容易的完成这个任务，在这里我记录一下这个过程。
1.上传图片存储到数据库中
在数据库中创建一个表，添加一下3个字段：
步骤一：在Web页面中拖一个FileUpload 控件，一个文本框用于输入名称和提交上传按钮
<asp:FileUpload ID="fuImage" runat="server" /><br />
<asp:TextBox ID="txtImageName" runat="server"/><br />
<asp:Button ID="btnUpload" runat="server" onClick="btnUpload_Click" Text="Upload" />
步骤二：在Web.Config文件内配置连接字符串。
<add name="ConnectionString" connectionString="Data Source=.\SQLEXPRESS;
AttachDbFilename=|DataDirectory|\Image.mdf;Integrated Security=True;
User Instance=True" providerName="System.Data.SqlClient"/>
步骤三：把下面的代码复制到上传按钮事件中。
protected void btnUpload_Click(object sender, EventArgs e)
{
Stream imgStream = fuImage.PostedFile.Inpu ......

ASP.NET Menu and IE8 rendering white issue
If you are using the ASP.NET Menu control, you might encounter under certain circumstances an issue where the menu appears as a white box in IE8 Standards Mode.
What IE8 is doing IS correct (by design), in the sense that in Standards mode IE8 is following the standards. Specifically, (element).currentStyle.zIndex returns "auto" in Standards mode when zindex has not been set. The ASP.NET Menu control assumes a different value.
I’d like to suggest a few possible workarounds to solve quickly the issue (note, you can use either one of them, depending on your scenario):
Overriding the z-index property
Using CSS Friendly Control Adapters
Adding the IE7 META tag to the website
1 – Overriding the z-index property
You can manually set the z-index property of the Menu items using the DynamicMenuStyle property of the asp:Menu ......
