You need to add an eventhandler to tell the GridView which page it should be looking at as I'm guessing you have done the .DataBind() in code. An example would be:

Markup:

<asp:GridView ID="GridView1" runat="server"
    EnablePagingAndSortingCallbacks="true"
    OnPageIndexChanged="GridView1_PageIndexChanged" />

Code:

    protected void GridView1_PageIndexChanged(object sender,
                                              GridViewPageEventArgs e)
    {
        GridView1.PageIndex = e.NewPageIndex;
        GridView1.DataBind();
    }

    GridView1.PageIndex = e.NewPageIndex;
    DataBind();

It means that the dataset associated with the gridview doesn't support paging.

It doesn't mean that you can't paged with it. To do that you will need to write your own code in PageIndexChanging event.
