假设原来是white色，在RowDataBound事件里写：

C# code
    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        e.Row.Attributes["onclick"] = "var rows=this.parentNode.rows……


------解决方案--------------------
<script>
var oldClr;
function chgClr(obj){
 var rows;
 oldClr=obj.style.backgroundColor;
 rows=this.parentNode.rows;
 for(var i=0;i<rows.length;i++){  
     rows[i].style.backgroundColor=oldClr;
     obj.style.backgroundColor='yellow';
 }
}
</script>

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
  e.Row.Attributes.Add["onclick","chgClr(this)"]; 
}
