I have the following code to bind datagrid

DataGrid dgGrid = new DataGrid();       
dgGrid.DataSource = dt;
dgGrid.DataBind();

this grid i'm writing to an excel file using system .io.file as below

 String path = Application["UpldPath"].ToString() + filename;
      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
               string renderedGridView = tw.ToString();
               File.WriteAllText(path, renderedGridView);

this is writing the excel to the specific path. But large numbers are coming with scientific notation.

You need to put explicit style on the specific column while doing the export to tell that it is a string column not an integer.
