And see whats wrong by Debugging your application Smile | :)

Trim is String.Trim function right ?
in C# you should have == instead one = while performing isEqual operation

Looking at it, this is classic ASP using VB - therefore Trim as a standalone function is correct, and the language is not C#.

In VB one = is correct.

Does it definitely step into the second if and execute Panel2.Visible = True

If it steps in and executes that line then there is a problem elsewhere eg the panel is hidden behind something

Try taking the statement outside of an Else If and have something like:

If Trim(txtflag.Text) = 0 Then
Panel1.Visible = True
Panel2.Visible = False
End If

If Trim(txtflag.Text) = 1 Then
Panel1.Visible = False
Panel2.Visible = True
End If

Let me know what this does.

I don't know it is perfect answer or not
Run your appplication When page is displaying all data right click it and see the source code od your page
Now check how they are arrange Find the common name like that and write jabascript to get all those by document.getElementByName method

Thanks and Regards

Cunningly enough, the exception tells you what is wrong. The path D:\webhost\textfiles\ isn't valid. I'm going to guess here that the TextFiles directory isn't present at this location.

I think you are not providing the proper path
Are you sure TextFiles folder exist in your application

I tried to run on localhost on my computer it work fine but it didn't work on my server.
I'm not sure how to coding for proper path on the server please see.

FileUpload.PostedFile.SaveAs(Server.MapPath("TextFiles//mydata.txt"));
//Is this right?

If I have my webhost like this ftp://webhost.example.com/... <-- and I put all file and folder here.
And i'm sure I the TextFiles folder is existed.

Thank you million sir,

OK Can't you access that and see folder exist or not ..........
Ok you can do one thing before uploading a file First check the Directory TextFiles exist or not if it not present there create with same name and put your file in that directory What you think my friend ?;)

The standard way of doing this would be to do the following:

if (!Directory.Exists(Server.MapPath("/TextFiles")))
  Directory.Create(Server.MapPath("/TextFiles"));

Then, you can do the save as operation. Note that the asp worker process will need permissions to write into your directory structure to do this.

Directory.CreateDirectory(fileName);
Response.Write("Not Exist");

Check your permissions. ASP.NET applications run under a special worker process and this process will need permissions to write to the file system.
