Columns not being generated when gridview datasource is set in code

ASP.NET

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true">
</asp:GridView>

C#

GridView1.AutoGenerateColumns = true;
GridView1.DataSource = db.Snippets.ToList();
GridView1.DataBind();
//shows us that we have no columns
giveJavascriptMessage(GridView1.Columns.Count.ToString());

//I want to be able to hide specific columns at the moment this returns an index out              of range
GridView1.Columns[0].visible=false;

Im using an entity framework model to populate the gridview.

When I run this code it creates the grid-view and populates it with the table but when I try to access the columns in the grid view there are none "giveJavascriptMessage(GridView1.Columns.Count.ToString());"
returns 0

Why are no columns being created although all data is shown on the page?
How can I get the columns to be created?

Thanks,

Solved it by defining the columns and disabling autogeneratecolumns

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<columns>
<asp:BoundField DataField="ID" />
<asp:BoundField DataField="Added" />
<asp:BoundField DataField="SnippetTitle" />
<asp:BoundField DataField="SnippetContent" />

Cheers
