Date format is corrupted while exporting GridView data to excel

Question

I have set UK culture on my machine. Date is getting exported correctly. I have written following code:
Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=IncidentsSearch.xls");
Response.ContentType = "application/vnd.xls";
//Ccreate string writer object and pass it to HtmlTextWriter object
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gv.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
But when I change my machine culture to US, date format gets corrupted. It exports date in "DD/MM/YYYY" format. When I apply filter on this column, it tries to convert these values to date format "MM/DD/YYYY". If there are 2 date values
like "05/08/2014" and "13/11/2014". When I try to change format of these 2 values to Long Date, it will try to convert it to MM/DD/YYYY format as US culture is set. So 1st values will be converted to 8 May, 2014 which is actually 5th Aug,2014.
For 2nd date value, it will not be able to convert it to date as 13 is not valid month. I want that when UK culture is set, it should automatically export date values in "DD/MM/YYYY" format and when US culture is set, it should automatically export
date values in "MM/DD/YYYY" format. Please suggest some solution.

Hi
This is the forum to discuss questions about VSTO develop (add-in, custom document). For your question is more about Web Form Data, I suggest you post this thread to asp.net data forum

 The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us.
Thank you for your understanding.
