ASP.NET DataList-MouseOver时行背景颜色更改

Question

I am trying to make the row background color change when moseover, but I could not make it work. I am not sure I use OnItemDataBound is correct or my codebehind is incorrect.

Please help. Thanks!

    </ItemTemplate>
     <FooterTemplate>
    </FooterTemplate>                
</asp:DataList>

Code behind

protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item)
    {

        e.Item.Attributes.Add("onmouseover", "this.className='BGMouseOver'");

        e.Item.Attributes.Add("onmouseout", "this.className='BGMouseOut'");

    }
}

I suggest CSS. You can find the idea here: div background color, to change onhover

Add CSS to the top:

<style type="text/css">
    .div_hover:hover { background-color: #000000; } <-- this is where you set your hover color
</style>

Basically, wrap everything in your ItemTemplate in a div, like so:

<ItemTemplate>    
    <div class="div_hover">
        [ItemTemplate stuff...]
    </div>
</ItemTemplate>
