Re: Client Authentication Dmitry Khudorozhkov9-Mar-07 10:37 Dmitry Khudorozhkov 9-Mar-07 10:37  HOW TO: Secure an ASP.NET Application Using Client-Side Certificates ------------------------- Don't worry, be happy ) &quot;Invalid Postback error&quot; Jeeva Mary Varghese9-Mar-07 3:03 Jeeva Mary Varghese 9-Mar-07 3:03  Hi All, I am working with the tree view control for a secure site , which has numerous nodes. But i get an error when i click on a node to expand it.I can see this only attimes(I guess it happens only when i don't give time for a node to expand and click on some other node to expand). The error is like:- Invalid postback or callback argument. Event validation is enabled using <pages enableeventvalidation="true"> in configuration or <%@ Page EnableEventValidation="true" %> in a page Can anyone tell me how to prevent it from happening Thanks & regards, Jeeva Re: &quot;Invalid Postback error&quot; ToddHileHoffer9-Mar-07 3:21 ToddHileHoffer 9-Mar-07 3:21  For whatever reason, when EnableEventValidation="true" you have to wait for the page to finish loading before you click on a control in the page. Otherwise you get an errror. In your page directive you could set EnableEventValidation="false".

Smith9-Mar-07 2:40 Marcus J. Smith 9-Mar-07 2:40  You will need to redirect the user to a page after submitting even if it is the same page. Also you will need to have some type of key that you can verify against to prevent this. If a user is on Page A and submits it goes to the DB, if they are returned to Page A or hit the button more than once it is going to be inserted over and over unless the Primary Key or Composite Key prevents this. Also if you redirect them to Page B and they hit back in their browser and submit again, well there is another potential insert.

It's working fine with internet explorer but when it comes to Mozilla Firefox it's not the same. No window is opened. What can I do to make it work properly?Is there a way to do it? Regards.

I suggest taking the time do write your own validation. Validating data with server side code is so much easier to write then client scripting. It also gives you so many more options to display information about the data to the user.

Regards. Tasleem Arif Re: validation summary MessageBox with Fire Fox Marcus J. Smith9-Mar-07 4:07 Marcus J. Smith 9-Mar-07 4:07  There are some options out there to edit the JavaScript that Microsoft uses for it's validations. You will probably need to look into that and edit it to use different options when it detects non IE browsers. CleaKO "I think you'll be okay here, they have a thin candy shell.

I dont want the variable to be displayed in the ULR menu. What would be the best way of doing this? Thanks. Re: Response.redirect szukuro9-Mar-07 2:19 szukuro 9-Mar-07 2:19  Use the Session object. On page 1: C# Session["variable"] = 0; Response.Redirect("~/Page2.aspx"); Then on page 2: C# int variable = (int)Session["variable"]; Re: Response.redirect Icarus1239-Mar-07 2:21 Icarus123 9-Mar-07 2:21  Is there another way of doing it without using Session variables?

Re: Laxmikant Lad please tell me Paddy Boyd9-Mar-07 5:06 Paddy Boyd 9-Mar-07 5:06  What code? Which language? What kind of value? if (value1 == value2) { } ??

Re: Password Decryption Laxmikant Lad9-Mar-07 1:26 Laxmikant Lad 9-Mar-07 1:26  hi u can't do decryption if ms would have provide decryption then what's the use of encrytion any body could decrypt the value. better way is if u just want to check the value then while comparing value encrypt it and then compare or else u will have to write ur own code for encryption as well as decryption Re: Password Decryption Marcus J. Smith9-Mar-07 6:51 Marcus J. Smith 9-Mar-07 6:51  Hashing is one way unlike other types of encryption it is not meant to be decrypted therefore to compare you hash the value and compare the hashes to each other.
