Re: How to Generate controls in web page ASP.NET 2.0?

3-Aug-06 3:00

Generating controls is possible but mainting the state is tricky. If you can't use a dataRepeater (even with your own custom XML or dataset) or gridview you may have to.

<br />
TextBox txt = new TextBox();<br />
        txt.Text = "Dynamically added to Page";<br />
        this.Controls.Add(txt);<br />

You will find that the value in the control will disappear on each postback.
Please refer to this link for more information about the page lifecycle.

But of course, that's all a "high level" overview of things

securing webapp with web.config

Shell32 is running on your server, not in the browser. Are you wanting to allow users to upload a file via a web application? The only thing you can do is use the html file input control.

Hi all,

I'm trying to set up my web app so that it doesn't display error/debugging/tracing messages to visitors.

I have already tried the following but i still get the Description:, Exception Details:, Parameter name:, Source Error: etc that you get from the debugger

My Web.Config has:
<trace enabled="false" pageoutput="false"> <compilation debug="false" explicit="false">

No pages have the debug set to true.

IIS has clientside debugging disabled.

Any ideas on how i can sort this out?

Thanks in advance.

hi Orb1t,

If you try below code in to web.config file and check that

<trace enabled="true" requestlimit="20" pageoutput="false"
="" tracemode="SortByTime" localonly="false">It is working but incase it is not work then try to flase tracing at page level like below:

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="Trace.aspx.vb"
Inherits="MCSDWebAppsVB.Trace" trace="True" %>

Chetan, Thanks for your reply + suggestions. I've tried both of them but had no luck with it, the server still returns the parser errors.

Any other ideas?

Cheers

I think what you are trying to do is set up custom errors. Turn the <customerros mode="On" defaultredirect="YouErrorPage.aspx">

Thanks ToddHileHoffer, this is exactly what i want to do. Big Grin | :-D

I just wondered whether there might be a way in which i could get it to use IIS' defualt script message'An error occurred on the server when processing the URL. Please contact the system administrator.' and avoid having to create customs + have the 302 redirects.

/customErrors<br />

Error while providing file download in webpage

I have to provide download of files in ASP.NET 2.0
I am using following lines of code.

try
{
Byte [] bytes = this.ContentController.GetFileContents(filePath);
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=File" + _fileExtension);
Response.AddHeader("Content-Length", bytes.Length.ToString());
Response.ContentType = "application/octet-stream";
Response.Buffer = true;
Response.BinaryWrite(bytes);
Response.Flush();
}
catch(FileNotFoundException fnfe)
{
this.ShowErrorMessage(this.GetErrorString(ResourceIdentifiers.DOCUMENT_FILE_NOT_FOUND_ERROR));
}
catch(Exception ex)
{
this.ShowErrorMessage(this.GetErrorString(ResourceIdentifiers.DOCUMENT_UNEXPECTED_ERROR));
}

Using above code, when one clicks on file link, a default download box of IE appears. If user clicks on Save, the file gets saved on disk and user can open that file. If user clicks on Open, it opens registered application with file type and says, file not found. Using same code I am able to open Word file but I cannot open Excel, PDF files.

Note: My application used Master pages, UIP Application Blocks. The code written above is inside a user control which gets loaded on view (webform) dynamically based on configration(xml) file.

Please can anyone suggest what could be going wrong in the piece of code because of which I am not able to open Excel/PDF files.

Apprciate your help.

Thanks and regards,
Ashish

VB.NEt code that works from my old application.

' The following code writes the pdf file to the Client’s browser.
Response.ClearContent()
Response.ClearHeaders()
Response.ContentType = "application/pdf"
Response.WriteFile(Fname) 'String location of the file
Response.Flush()
Response.Close()
'delete the exported file from disk
System.IO.File.Delete(Fname)
