Dynamically created controls must be re-created on every postback. From the code you posted it appears that you could do this in markup instead. If not, you'll have to re-create the dynamic controls on every postback.

Your mark up code should be:

XML

    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"          OnRowCommand="GridView1_RowCommand"          OnRowEditing="GridView1_RowEditing"/>
}

Key thing is that you need to move your code from Page_Load to Page_Init. Things added in the Page_Load last only for the lifecycle of one postback.

C#

protected void Page_Load(object sender, EventArgs e)
{
     BindGridView(); 
}
