Question

Hi All ,

 

I have issue on Excel Export. While I do have String Coulmn in database but which contains Number. While I export.its how some other formats.

 

8.00318E+12

 

How can I resolve this issue? I can show the code too. If anyone knows just suggest me with example.

 

The following code i just used in Excel Export ..

//Create a dummy GridView
GridView GridView1 = new GridView();
GridView1.ShowFooter = true;
GridView1.AllowPaging = false;
GridView1.DataSource = Dt2;
GridView1.DataBind();
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=MemberHistory.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
for (int i = 0; i < GridView1.Rows.Count; i++)
{
//Apply text style to each Row
GridView1.Rows[i].Attributes.Add("class", "textmode");
}
GridView1.RenderControl(hw);
//style to format numbers to string
string style = @"<style> textmode { mso-number-format:General } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();

Thanks in Advance
