DataList数据显示小技巧

上次项目中在首页中要求显示最新的六条公告，我采用了DataList来处理，但当数据少于六条时就显示不按常规来显示了，后经处理得以解决，现记录下来以供参考：
     

<td width="504" bgColor="#ffffff" height="167" valign="top"><asp:datalist id="DataList1" runat="server" Width="504px">
                                                    <ItemTemplate>
                                                        <FONT face="宋体">
                                                            <TABLE id="Table1" cellSpacing="0" cellPadding="0" width="500" border="0">
                                                                <TR>
                                                                    <TD>
                                                                        <asp:Image id="Image1" runat="server" Width="4px" height="4" ImageUrl="Image/index-icon1.gif"></asp:Image>&nbsp;
                                                                    </TD>
                                                                    <TD width="367" height="10"><FONT face="宋体"><A  title='<%# DataBinder.Eval(Container.DataItem,"Title")%>' href='javascript:viewNotice("Admin/Board_Popup.aspx?Seq=<%#DataBinder.Eval(Container.DataItem,"Seq")%>");'><font color="Black"><%# SubString(DataBinder.Eval(Container.DataItem,"Title").ToString(),28) %></font></A></FONT></TD>
                                                                    <TD><FONT face="宋体">&nbsp;&nbsp;&nbsp;</FONT>
                                                                        <asp:Label id=Label1 runat="server" Width="100px" height="10" Text='<%# ChangeDate(DataBinder.Eval(Container.DataItem, "InputDate").ToString()) %>'>
                                                                        </asp:Label></TD>
                                                                </TR>
                                                            </TABLE>
                                                        </FONT>
                                                    </ItemTemplate>
                                                </asp:datalist></td>

在后台代码中添加：

  DataList1.Height=ds.Tables[0].Rows.Count*27;

public string SubString(string str,int i)
  {  
   string temp;
   if(str.Length>i)
   {
    temp=str.Substring(0,i);
    
    
    temp=temp+"";

    return temp;
   }
   else
    return str;  
  }

public string ChangeDate(string date)
  {
      //string temp=Convert.ToDateTime(date).ToShortDateString();

   string temp=DateTime.Parse(date).ToString("yyyyMMdd");
   temp=temp.Substring(0,4)+"-"+temp.Substring(4,2)+"-"+temp.Substring(6,2);
   return temp;
  }

即设定DataList高度，这样就使得数据显示时有几条显示几条而且按固定高度显示。其他的数据绑定就和平常一样。
