问题描述

HI，

如何将数据从sql数据库绑定到数据列表控件.

我有一个数据列表控件，而里面有一个ASP图像控件.
在我的数据库中，我仅保存了图像名称.我需要在数据列表控件中显示图像.

我已经使用了下面提到的代码.

How to bind datas from sql database to datalist control.

I have a datalist control and inside that it has a asp image control.
In my database i have saved the Image name only. and i need to show the images in the datalist control.

I have used the code below mentioned.

<asp:Image ID="imgItem" runat="server" Height="75px" ImageUrl='../../Content/images/thumbs/sub/<%# Eval("Sub_Item_Img") %>' Width="75px" />

有什么方法可以使用asp图像控件显示图像. ?
