选定gridview的一行使其变色

Question

 protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
    {
        GridView1.Rows[e.NewSelectedIndex].Attributes.Add("onclick", "OnFocus(   '#000000','#FFFFFF','#FFFFFF','#bcbcbc'   );");
    }这个为什么不行?不用SelectedIndexChanging这个事件么?

this.dg.ItemDataBound += new System.Web.UI.WebControls.DataGridItemEventHandler(this.dg_ItemDataBound1);protected void dg_ItemDataBound1(object sender, DataGridItemEventArgs e) 
{ 
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) 
{ 
//颜色交替   
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor='Gainsboro'"); 
if(e.Item.ItemType == ListItemType.Item) 
{ 
e.Item.BackColor=System.Drawing.Color.LightCyan;
e.Item.Attributes.Add("onmouseout", "this.style.backgroundColor='LightCyan'"); 
}  if(e.Item.ItemType ==ListItemType.AlternatingItem) 
{ 
e.Item.BackColor=System.Drawing.Color.White;
e.Item.Attributes.Add("onmouseout", "this.style.backgroundColor='White'"); 
} 
}

Answer 2

dg_ItemDataBound1写在这里：private void InitializeComponent()
{ 
this.dg.ItemDataBound += new System.Web.UI.WebControls.DataGridItemEventHandler(this.dg_ItemDataBound1);}
