Hi experts,

and have to save that excel file in project folder.

I have tried with this sample code but its not working

Quote:
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
DataGrid dgGrid = new DataGrid();
dgGrid.DataSource = dt;
dgGrid.DataBind();
//Get the HTML for the control.
dgGrid.RenderControl(hw);
//Write the HTML back to the browser.
//Response.ContentType = application/vnd.ms-excel;
Response.ContentType = "application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
this.EnableViewState = false;
Response.Write(tw.ToString());
Response.End();

Do it in following way
public void ExportToExcel(DataTable dt)
   {
       if (dt.Rows.Count > 0)
       {
           string filename = "Filename.xls";
           System.IO.StringWriter tw = new System.IO.StringWriter();
           System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
           DataGrid dgGrid = new DataGrid();
           dgGrid.DataSource = dt;
           dgGrid.DataBind();

           dgGrid.RenderControl(hw);
           Response.ContentType = "application/vnd.ms-excel";
           Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
           this.EnableViewState = false;
           Response.Write(tw.ToString());
           Response.End();
       }
   }

this issue something different. This error comes at the time of resource not available. Put try catch to see where is coming and why??
