Hi,
I'm using the following code to Export the crystal report but it exporting blank page.
protected void Page_Load(object sender, EventArgs e)
{
 ReportDocument oReport = new ReportDocument();
 if (!Page.IsPostBack)
  {
   oReport.Load(Server.MapPath("Reports/rptCropSoil.rpt"));
   Crtv.ReportSource = oReport;
  }
  ViewState["CrtvDataSource"] = oReport;
}
protected void BtnExport_Click(object sender, ImageClickEventArgs e)
{
 ReportDocument oReport = new ReportDocument();
 oReport = (ReportDocument)ViewState["CrtvDataSource"];
  oReport.ExportToHttpResponse(ExportFormatType.Port ableDocFormat, Response, true, "Your Exported File Name");
}

This code is saving Blank page on my system. But if i provide the complete code on page_load i.e.

ReportDocument oReport = new ReportDocument();
if (!Page.IsPostBack)
  {
   oReport.Load(Server.MapPath("Reports/rptCropSoil.rpt"));
   oReport.ExportToHttpResponse(ExportFormatType.Port ableDocFormat, Response, true, "Your Exported File Name");
  }

than Working fine. But i want to perform this on Button click. Please help me.


Thank you so much
