1) on a button click, new web page(New.aspx) should open, leaving the previous one opened.

target ='_blank' to your button.

C#

ScriptManager.RegisterStartupScript(page,
                typeof(Page),
                "Redirect",
                "window.open('./error.aspx');",
                true);

[EDIT]According to your changed requirement

Just check

try
{
if (File.Exists(filePath))
            {
                FileStream sr = new FileStream(filePath, System.IO.FileMode.Open);
                XmlTextReader xtr = new XmlTextReader(sr);
                 ds.ReadXml(xtr);
