System.IO.StringWriter sw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);

Answer 1

You can do this:

private void ExportGridView()
{
    System.IO.StringWriter sw = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter htw = new System.Web.UI.HtmlTextWriter(sw);

    // Render grid view control.
    gvFiles.RenderControl(htw);

    // Write the rendered content to a file.
    string renderedGridView = sw.ToString();
    System.IO.File.WriteAllText(@"C:PathOnServerExportedFile.xlsx", renderedGridView);
}
