For Dynamically created TextBox, You need to keep in mind some point !
You have to create the Textbox Before Page Load. Create your text box in Page_PreInit(), otherwise, you will never get the ViewState and Postback Data. Because Postback data and View state data loads just before the Page_Load.
Hope this will help you !

Hi guys! I am developing a page that gets a PFD file from a FTP directory and then reads it using the IO stream and then output it to the use in the same page.

I have built the page, but I am getting an error everytime I try it that says "there was an error reading this document".

Well, this is the code I am using:

Const username As String = "pdfuser"
Const password As String = "pdfpass"

Dim URI As String = "ftp://192.168.20.10/PDF/9006.pdf"

Dim ftpReq As FtpWebRequest = DirectCast(System.Net.WebRequest.Create(URI), FtpWebRequest)
ftpReq.Credentials = New NetworkCredential(username, password)
ftpReq.UsePassive = False
ftpReq.UseBinary = True
ftpReq.Method = WebRequestMethods.Ftp.DownloadFile

Dim ftpRes As FtpWebResponse = DirectCast(ftpReq.GetResponse, FtpWebResponse)
Dim responseStream As IO.Stream = ftpRes.GetResponseStream
'loop to read & write to file
Response.ContentType = "Application/pdf"
Dim FileSize As Long
FileSize = 1024
Dim Buffer(CInt(FileSize)) As Byte
Dim count As Integer = 0
Do
count = responseStream.Read(Buffer, 0, Buffer.Length)
Response.BinaryWrite(Buffer)
Response.Flush()
Loop Until count = 0 'see Note(1)
Response.End()

Please help..

A pdf on an Iframe

I want to display a pdf document on an Iframe and what gets displayed on my frame is :

"Server Error in '/LearningConceptsA' Application.
--------------------------------------------------------------------------------

The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /LearningConceptsA/Images/Variable[1].pdf

--------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:2.0.50727.3082; ASP.NET Version:2.0.50727.3082 "

Have I placed it in the right folder? may be not. someone suggested I place it in the App_Code folder, which I can't see.

Well the code behind the dropdownlist looks like:
"protected void ddlBasicConcept_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlBasicConcept.SelectedValue.Equals("Variable"))
{
frmWord.Attributes.Add("src", "Images/Variable[1].pdf");"
Please help a junior programmer in need.

Are you using alert and location.window.href in the same javascript function? If yes it should work, because as far as I know is alert blocking... Could you post a bit of the code, for a better understanding?

Hi,
<
string script = "<script language='javascript'>";
script += "alert('" + patientId + "');\n";
script += "</script>";
RegisterStartupScript("StartUp", script);

Response.Redirect("NewAppointment.aspx");>

Because of this Page is redirecting to another page and pop up is not coming

Regards,

Amit patel

In that case, you shouldn't use Response.Redirect on the server. Do the redirect within your script:

...
script += "window.location.href='http://Myserver/Myclient/NewAppointment.aspx';";
...

if you can do this with javascript then
you can use alert box like this alert(pass the value of generated id value)
and then redirect to next page.

Sounds like the perfect use-case for AJAX...http://www.asp.net/ajax/[^]
