Web Forms :: How To Change Linkbutton Selected Items Color

I use datalist and linkbutton in page that bind from database below is code:

<asp:DataList ID="DLclass" runat="server" Visible="false">
<ItemTemplate>
<asp:LinkButton ID="Linkbtnclass" runat="server" CssClass="lbldasteM"
CommandArgument='<%# Eval("Name") %>' OnClick="Linkbtnclass_Click"><%# Eval("Name") %></asp:LinkButton>

[Code] ....

And behind code:

protected void Linkbtnclass_Click(object sender, EventArgs e)
{
rptPager.Visible= Lblcontinue.Visible = !(rptPager2.Visible = DLMostanad.Visible=true);
(sender as LinkButton).ForeColor = System.Drawing.ColorTranslator.FromHtml("#fb00c2");
this.GetCustomersPageWiseMC(1, (sender as LinkButton).CommandArgument);
BindDataListD(DLclassC, "classTI_documentry");
}

in above code in this line:

(sender as LinkButton).ForeColor = System.Drawing.ColorTranslator.FromHtml("#fb00c2");

I define that when I select Item from datalist( linkbutton) that bind from database color of text will be change below is image:

I show it with red arrow now here when I select other linkbutton (i.e text under last text) it dosen't change last selected text to defualt color:

as you see in above image second selected text show with green arrow

I want when I select second text(link button) it changes first selected text to default color...
