Same link repeats multiple times in a page clicking one of them changes the color of all same links

i am working on a rad grid where a link related to same page repeats itself. when i click on one of the links, and then return to the page after navigating to the destination page, all the same links color changes.

what i want is when i click a single link only that should be shown as visited link.

how do i implement this? i am using the link as follows:

<telerik:GridTemplateColumn UniqueName="Sequence" HeaderText="Seq">
                        <ItemTemplate>

                        </ItemTemplate>
                    </telerik:GridTemplateColumn>

This is the long version because I don't know how much you already know.

When you visit a link its color changes to a 'visited' color. This color is determined by the user's browser. Each website you visit can choose to override this using CSS.

a:visited { color: green; }

Every page you visit (regardless of site) that includes the exact same link will use that site's visited css color. You can add a querystring to the the link if you want it to be unique.
