Exporting HTML Table to Excel via Page Method
I have the following code on the client side for retrieving data from the HTML Table and then send it to the server through the page method:
function dtExportToCSV(dataTable)
var elements = dtDataToJSON(dataTable);
var headers = dtHeadersToJSON(tableSelector);
jQuery.ajax(
type: “POST”,
url: “Report.aspx/exportToCSV”,
data: “‘elements’: ” + elements + “, ‘headers’: ” + JSON.stringify(headers) + “”,
contentType: “application/json; charset=utf-8″,
dataType: “json”,
success: function(msg)
if (msg.d)
else
},
error: function(xhr, ajaxOptions, thrownError)
alert(xhr.statusText);
});
}
Then I use the following code on the server side, to export the retrieved data to CSV file.
///
///
//////[WebMethod(EnableSession=true)]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static bool exportToCSV(List
try
string attachmentType = “attachment; filename=ShortageReport.csv”;
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.AddHeader(“content-disposition”, attachmentType);
HttpContext.Current.Response.ContentType = “text/csv”;
HttpContext.Current.Response.AddHeader(“Pragma”, “public”);
writeHeadersInfo(headers);
HttpContext.Current.Response.End();
catch (Exception ex)
Console.WriteLine(ex.Message);
return false;
}
But I get this expcetion: Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.
Does anyone knows how to handle this issue?
Any help would be highly appreciated! Thanks in Advance!

But it doesn’t show up the save file dialog…
