Answer 1

Update: Use

lnkbtn.Attributes.Add("style", "font-weight:bold;");

Eg.:

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    string ID = Page.Request.QueryString.Get("ID");
    LinkButton lnkbtn = (LinkButton)e.Item.FindControl("lnkbtn");
    lnkbtn.Attributes.Add("style", "font-weight:bold;");
}

I think you want to change the style of the selected LinkButton.

You can do that using CSS.

Eg.:

a:link {color:#FF0000;}      /* unvisited link */
a:visited {color:#00FF00;}  /* visited link */
a:hover {color:#FF00FF;}  /* mouse over link */
a:active {color:#0000FF;}  /* selected link */
