Question

I have some problem with my open new window popup which it can read my path and it like throw away my “/” sign in it. So it will be see like this “C:UsersKHAIRADesktopheitechHibah Total v1.2/Secure/PDF Folder”

Can anyone help me to make it look/read like this “C:Users/KHAIRA/Desktop/heitech/Hibah Total v1.2/Secure/PDF Folder”.

I have open button in gridview that will open new window and view the pdf file here the coding from ViewDocument.aspx

string commandName = e.CommandName.ToString().Trim();
GridViewRow row = GridView1.Rows[Convert.ToInt32(e.CommandArgument)];
string folderName = ConfigurationManager.AppSettings["folderPDF"].ToString();
string path = Server.MapPath("~") + "/Secure/";
string fullPath = path + folderName;
string[] filePaths = Directory.GetFiles(fullPath, "*.pdf"); 
switch (commandName)
{
    case "Open":                       
        string script = "<script language=\"JavaScript\">\n";
        script += "window.open ('OpenForm.aspx?path=" + row.Cells[0].Text;
        script += "','CustomPopUp', config='height=500,width=1024, toolbar=no, menubar=no, scrollbars=yes, resizable=yes,location=no, directories=no, status=no')\n";
        script += "</script>";

        this.ClientScript.RegisterStartupScript(this.GetType(), "onload", script);
        break;

for the OpenForm.aspx.cs coding :

catch(Exception ex)
{
    try
    {
        string paths = Request.QueryString["path"].ToString();
        bool fileExist = File.Exists(paths);
        if (fileExist)
        {
            Response.ContentType = "Application/pdf";
            Response.TransmitFile(paths);
        }
        else
        {
            Label1.Text = "File Not Exist";
        }
    }

However, i realize that the problem is from here

string paths = Request.QueryString["path"].ToString();

First things first.

The local system path separator is \ e.g. C:\Windows.

/ is for web e.g. http://stackoverflow.com/questions/9902129/how-to-make-the-path-have/9902194#9902194

For a single \ you have to put \\ (remember escape sequence)

Or

Use String Verbatim

string path = @"C:\Users\KHAIRA\Desktop\heitech\Hibah Total v1.2\Secure\PDF Folder"

Or

Use Path.Combine method of System.IO namespace like

Path.Combine("C:", "Users");

It will give return a string

C:\Users
