我自己写的一个投票结果显示,其中设定票数最多的那个进度条为100%。
public class voteresult : System.Web.UI.Page { protected System.Web.UI.HtmlControls.HtmlTableCell td_vote; protected System.Web.UI.HtmlControls.HtmlTable tab_result; private void Page_Load(object sender, System.EventArgs e)// 在此处放置用户代码以初始化页面 { tab_result=new HtmlTable(); string voteid=Request.Params["voteid"]; string optionid=Request.Params["optionid"]; CommonFunction.SQLConnection scon=new SQLConnection(); System.Data.DataTable dt; System.Web.UI.HtmlControls.HtmlTableCell tc; System.Web.UI.HtmlControls.HtmlTableRow tr; string sql=""; sql="update voteinfo set optioncount=optioncount+1 where voteid="+voteid+" and optionid="+optionid; scon.OperationRecord(sql); sql="select optionstr,optioncount from voteinfo where voteid="+voteid;dt=scon.Query(sql); int i=0; int length=0; while(i<dt.Rows.Count) { if(length<(int)dt.Rows[i].ItemArray[1]) length=(int)dt.Rows[i].ItemArray[1]; i++; } i=0; td_vote.InnerHtml="<table border=\"1\" cellspacing=\"1\" cellpadding=\"1\" align=\"center\">"; while(i<dt.Rows.Count) { td_vote.InnerHtml+="<tr>"; td_vote.InnerHtml+="<td>"; td_vote.InnerHtml+=(string)dt.Rows[i].ItemArray[0]; td_vote.InnerHtml+="</td><td width=\"200\">"; //tc=new HtmlTableCell(); //tr=new HtmlTableRow(); //tc.InnerText= //tr.Cells.Add(tc); //tc=new HtmlTableCell(); td_vote.InnerHtml+="<img src=\"images/long.gif\" width=\""+(((int)dt.Rows[i].ItemArray[1]*100/length)*2)+"\" height=\"9\">"; //tc.InnerHtml= //tr.Cells.Add(tc); td_vote.InnerHtml+="</td><td>"; td_vote.InnerHtml+=((int)dt.Rows[i].ItemArray[1]).ToString();; //tc=new HtmlTableCell(); //tc.InnerText= td_vote.InnerHtml+="</td></tr>"; i++; } td_vote.InnerHtml+="</table>"; }
