ASP.NET中DataList数据绑定汇总
a、前台aspx文件代码：
<asp:DataList ID="dataListDocument" runat="server" Width="400px">
<ItemTemplate>
<table class="style1">
<tr>
<td class="style3" rowspan="2"><img src ="Images/Btn/icon_arrow_5.gif"/>
</td>
<td class="style7"><asp:Label ID="lblCommentMatter"
runat="server" Text ='<%# GetShot(Eval("Title"))%>'
ToolTip='<%# Eval("Title")%>'></asp:Label>
</td>
<td class="style5">
评论：<asp:Label ID="lblCommentTime" runat="server"
Text='<%#Get(Eval("CommentOnMatter")) %>' ToolTip='<%#
Eval("CommentOnMatter")%>'></asp:Label>
</td>
<td class="style6">
<a href='..//?&DocumentId=<%#
DataBinder.Eval(Container.DataItem,"DocumentId")%>&Classify=<%#
DataBinder.Eval(Container.DataItem,"Classify")%>&SmallClass=<%#
DataBinder.Eval(Container.DataItem,"SmallClass")%>&UploadMemId=<%#
DataBinder.Eval(Container.DataItem,"UploadMemId")%>'>
查看</a></td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>
CSS格式约束
<style type="text/css">
.styles1
{
width: 100%;
}
.style1
{
width: 100%;
height: 22px;
height:24px!important;
font-size:12px; color: #0000FF;
padding:2px 0 7px 0;
padding:0px!important;
padding-top:0px;
}
.style3
{
width: 11px;width: 12px!important;
}
.style5
{width: 280px!important;}
.style6
{width: 25px!important;}
.style7
{
width: 75px;
}
</style>
b、后台cs文件代码：
Document document = new Document();
dataListDocument .DataSource = document.NewDocument(0);
dataListDocument.DataBind();
//控制前台字符长度
public string Get(object obj)
{
string str = obj.ToString();
if (str.Length > 16)
{
return str = str.Substring(0, 16).ToString() + "....";
}
return str;
}
public string GetShot(object obj)
{
string str = obj.ToString();
if (str.Length > 4)
{
return str = str.Substring(0, 4).ToString() + "....";
}
return str;
}
3、图像路径读取
A.<asp:DataList ID="dataListNewCritique" runat="server" Width="560px">
<ItemTemplate>
<td class="style3" rowspan="2"><asp:Image ID="imgPhoto"
ImageUrl='<%#
ImageS(DataBinder.Eval(Container.DataItem,"PhotoPath"))%>'
runat="server" Height="17px" Width="15px" />
</ItemTemplate>
</asp:DataList>
B.<img
src="<%#"../Images/MemPhotos/"+DataBinder.Eval(Container.DataItem,
"PhotoPath") %>" width="50px" height="70px" />
//读取页面头像绑定
protected string ImageS(object PBface)
{
if (PBface == null)
{
return "~/Images/MemPhotos/photo.gif";
}
else
{
try
{
if (File.Exists(AppDomain.CurrentDomain.BaseDirectory + "Images\\MemPhotos\\" + PBface))
{
return "~/Images/MemPhotos/" + PBface;
}
else
{
return "~/Images/MemPhotos/photo.gif";
}
}
catch
{
return "~/Images/MemPhotos/photo.gif";
}
}
}
