|M| 第二贴：如何将一个我用Repeater输出的Table转为Execl导出 谢谢 急
http://community.csdn.net/Expert/topic/5558/5558008.xml?temp=.6493799
用幕白兄的：
public static void ExportExcel(ref System.Web.UI.WebControls.Repeater rp, string strFileName)
{
//DataTable dt = (DataTable)this.Session[ "GridToExcel "];
//if (dt==null) return;
strFileName= System.Web.HttpUtility.UrlEncode(strFileName,System.Text.Encoding.UTF8);
//dtgList.DataSource = DataClass.ExecuteDataTable(dtgList.strSQL).DefaultView;
//dtgList.EnableViewState =false;
System.Web.HttpContext.Current.Response.Clear();
System.Web.HttpContext.Current.Response.Buffer = true;
System.Web.HttpContext.Current.Response.Charset = "gb2312 ";
System.Web.HttpContext.Current.Response.AppendHeader( "Content-Disposition ", "online; filename= " + strFileName + ".xls ");
System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding( "gb2312 ");
System.Web.HttpContext.Current.Response.ContentType = "application/ms-excel ";
//System.Web.HttpContext.Current.EnableViewState = false;
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo( "zh-CN ",true);
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCItrad);
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
//oHtmlTextWriter.Write( " <table width= '100% ' border= '1 '> ");
rp.RenderControl(oHtmlTextWriter);
//oHtmlTextWriter.Write( " </table> ");
rp = null;
System.Web.HttpContext.Current.Response.Write(oStringWriter.ToString().Replace( " <td ", " <td STYLE= 'MSO-NUMBER-FORMAT:\\@ ' "));
System.Web.HttpContext.Current.Response.Buffer = false;
System.Web.HttpContext.Current.Response.End();
}

可以生成
但是当我的repeater中包括了控件的时候就会出错：
类型“CheckBox”的控件“rp_ctl01_CheckBox3”必须放在具有 runat=server 的窗体标记内。
谢谢

[解决办法]
直接将table(服务器控件)render成html然后作为字符串流下载:
/// <summary> 控件存现为Html字符串 </summary>
public static string RenderHtml(Control c){
StringBuilder b = new StringBuilder();
StringWriter w = new StringWriter(b);
HtmlTextWriter htw = new HtmlTextWriter(w);
c.RenderControl(htw);
c.Dispose();
return b.ToString();
}
下载:
public static void ExportString(string s,string fileName){
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.ContentEncoding = System.Text.Encoding.GetEncoding( "gb2312 ");
response.AppendHeader( "Content-Disposition ", "attachment; filename= "+fileName);
response.ContentType = GetMime(fileName);
StreamWriter writer = new StreamWriter(response.OutputStream,response.ContentEncoding);
try {
writer.Write(s);
writer.Flush();
}
finally {
writer.Close();
response.End();
}
}

[解决办法]
public override void VerifyRenderingInServerForm(Control control) { //base.VerifyRenderingInServerForm(control); }把这个放在页面的代码中
