Solution 1

While loading the page, inside page load, check the previous page URL with the below code.

C#

Request.UrlReferrer

Quote:
HTTP_REFERER Returns a string containing the URL of the page that referred the request to the current page using an tag. If the page is redirected, HTTP_REFERER is empty

Compare the URL with the page where you have the links.

So, if it matches, then allow. Otherwise, redirect to where ever you want.

I think user is asking for something else.
I think :
He is asking for Group wise menu permission

Yes, seems like. But still unclear. Where the group thing is stored? Anyways, let him reply to my answer first. We can take that forward after that.

Hi Tadit Dash,I think you wrong this issue . NOTE : I want to check in a link page , I think i should check in Page_Load of page .Example: User have "group A" only access Link 1.aspx and Link 4.aspx. If user type http://contoso.com/link2.aspx , it will deny and redirect page Default.aspx. User have "group B" only access Link 2.aspx , if user type http://contoso.com/link1.aspx , it will deny and redirect page Default.aspx,...etc.
Please read it clearly.
Thank you

Okay, so check this condition on Page Load and redirect accordingly.
