I have the following entries in the css file.

a.intervalLinks { font-size:11px; font-weight:normal; color:#003399; text-decoration:underline; margin:0px 16px  0px  0px; }  
a.intervalLinks:link { text-decoration:underline; }  
a.intervalLinks:hover { text-decoration:none; }  
a.intervalLinks:visited { text-decoration:underline; }  
a.selectedIntervalLink { font-size:12px; font-weight:bold; color:#003399; text-decoration:none; margin:0px 16px 0px 0px; }  
a.intervalLinks:active { text-decoration:underline; font-size:large ;  }

Whenever i take the click on some links (not shown) which is embedded in the webpage ..i can see the change in the link

a.intervalLinks:active { text-decoration:underline; font-size:large ;

(the font of the link will become large)

but after clicking the page refreshes ..the changes will go away

i want to keep the change for ever in that link ...even there is a page refresh

i understood that ..this can achieved only throughg the code behind of asp.net

Following code should work:but unfortunately its not ..could anyone help?

protected override void OnInit(EventArgs e)
        {
            rptDeptList.ItemDataBound += new RepeaterItemEventHandler(rptDeptList_ItemDataBound);

        }

        void rptDeptList_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.DataItem == null)
                return;
            LinkButton btn = (LinkButton)e.Item.FindControl("LinkButton1");
            btn.Attributes.Add("class", "intervalLinks");  

        }

Current html code for links has been shown below :

<ItemTemplate>
<div class='dtilsDropListTxt'><div class='rightArrow' ></div>
<asp:LinkButton ID="LinkButton1" runat="server" Text=<%#DataBinder.Eval(Container.DataItem, "WORK_AREA")%>  
CssClass="intervalLinks" OnClick="LinkButton1_Click" ></asp:LinkButton>
</div>
</ItemTemplate>

Could anyone help?
