本例将在SharePoint 2010站点上构建一个每日一句Web部件。如果你的电脑上还没有装SharePoint 2010环境,可以先从配置 SharePoint 2010开发环境开始做起。为了能够开发该webpart,你除了需要SharePoint 2010外,还需要VisualStudio 2010。

下图是最终完成时的效果。它会每天随机从列表里获取数据。

步骤

新建一个visual web part,命名为TOTD。

添加你希望将webpart部署到的站点的URL 。

点击完成并删除默认创建的webpart。然后新加一个visual web part,如下图所示:

在设计界面上放置一个Image Box,两个lable,然后根据需要调整表格的布局。 

 HTML代码

<table style="width: 409px">
    
<tr>
        
<td rowspan="2" width="100px">
            
<asp:Image ID="ImgAuthor" runat="server" Width="100px" Height="100px" />
        
</td>
        
<td style=" height:16px" valign="top">
            
<asp:Label ID="lblTOTD" runat="server" Font-Italic="True" Font-Names="Calibri" 
                Font-Size
="12pt" style="z-index: 1; left: 120px; top: 29px; width: 376px" 
                ForeColor
="#003399"></asp:Label>
        
</td>
    
</tr>
    
<tr>
        
<td align="right" valign="top">
            
<asp:Label ID="lblAuthor" runat="server"  Font-Names="Calibri" Font-Size="9pt" 
                style
="z-index: 1; left: 239px; top: 97px; text-align:right; height: 13px; width: 252px"></asp:Label>
        
</td>
    
</tr>
</table>

控件命名为,ImageBox:ImgAuthor,Lable:lblTOTD,lblAuthor。现在你得到类似如下的设计界面。

OK。现在你已经完成了部件的设计工作,开始编写后台代码。

            SPListItemCollection collItem
