Implement following logic:
dgrd.Columns(i).Visible = False
Note: i represents column index

Ur solution will work fine but this will make ur page quite bulky & also will increase the redundancy of ur logic.
From maintainance perspective ur solution might proved to be bit dicy.

Validation of viewstate MAC failed

Hey peeps,

I have a site running .net 2.0. The site is hosted on a server farm.
On the guestbook page i seem to get attacked by a bot trying to post some nasty urls. But the bot don't succed, it gets a "Validation of viewstate MAC failed" error. I catch all errors in the global file and log it. Therefor i can see this happens quite often, more than 20 times a day.
I have posted a trace file where the exception happens here.

The header of the guestbook files is as followed.

<%@ Page Language="C#" ValidateRequest="false" MasterPageFile="~/Default.master"
AutoEventWireup="true" CodeFile="Guestbook.aspx.cs" Inherits="Guestbook" Title="Untitled Page" Culture="da-DK"%>

I have been forced to turn Validaterequest off, to allow users to html format their posts in the guestbook.

Does anybody have an idea to how i can prevent this error from happening.

-Anders

Why don't you block such kind of bots with CAPTCHA ?

It looks like it might be a cross page posting error - someone is trying to post to your page and it can't handle it.

Google a bit on cross page posting for advice.

Sounds like this could be my problem, i will try google it some more and see if i can come up with a solution myself. But if anybody should have one at hand, i would greatly appreciate it.

Tanks you Paddy, for the help so far.

That is a date literal used by the MS Access database. If you are using any other database, it's apostrophes around the date instead.

Also, the database might not recognice that exact date format. You should use a parameterised query, so that you don't have to format the date as a string.

Best way to check session values

I have a site and I want to perform a simple check on each page that session exists.
The exact check on each page will be as below:
If session doesn't exist for the user redirect it to login page

Do I need to write the code on each .cs file or is there a better way to perfome this operation.

Please suggest!

if u want to do that, its fine..but i think u can make a class for the session check..so, if u want to check the session all you need is call the class function for session check

Kind Regard,

Session is not in the context of a class ? So you need to get Page object here to access session. Is it a good practice ?

Sounds like your DB is set up so the user you're logging in as doesn't have permission to do a SELECT.
