Pretty much, its an easy to use querying engine which automatically creates objects that you can use within your ASP.NET project. You can use LINQ querying if you like, or you can use the SubSonic preferred way as demonstrated below;

Want to bind a gridview?

var categories = category.All();
gvList.DataSource = categories;
gvList.DataBind();

Boom. Done.

<pre lang="csharp" line="1">
int iLineID = 1;
category delCat = category.SingleOrDefault(x => x.id == iLineID);
delCat.Delete();

Too easy right?

What about adding a new record?

category newCat = new category();
newCat.name = "Dummy category name";
newCat.Add();

How easy is that? Go grab SubSonic now!

As an example I had a gridview which had a different background for alternating rows.

<AlternatingRowStyle CssClass="odd" /></code>

And my CSS was something like

.odd { background-image: url(../graphics/tealbg.gif); }

The Solution

The easy (and maybe a little messy) way to solve this is to force the page to use IE7 compatibility. You can do this by adding the following to your tag.

<meta http-equiv="X-UA-Compatible" content="IE=7" />

Note: The above meta tag MUST appear before any link tags (stylesheet includes for example)

The GridView fired event PageIndexChanging which wasn’t handled

To setup paging with Gridviews, you also need to set the page index property to the new page that you wish to view. Funny enough, this is extremely easy to do. See below for a code example written in C#.

The ASPX page

<asp:GridView ID="gvList" runat="server" AutoGenerateColumns="true" AllowPaging="true" PageSize="10" OnPageIndexChanging="gvList_PageIndexChanging">

and the C# code

    protected void gvList_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        bindGrid();

        gvList.PageIndex = e.NewPageIndex;
        gvList.DataBind();
    }
