Hide Column In Grid

This is my html mark-up and adding the visibility to false in the div tag hides the actual data itself, but just leaves a blank column. I tried to access the div tag (yes I added the runat="server" tag to the html) and attempted to access it like so hideme.Visible = true; which threw a compile error of

Does not exist in the current context.

What should I alter/modify to ensure that this column is completely hidden from my grid?

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" ShowFooter="true"
        onrowdatabound="GridView1_RowDataBound"  onrowcreated="GridView1_RowCreated">
    <Columns>
      <asp:BoundField DataField="abcd" HeaderText="abcd" />
      <asp:BoundField DataField="def" HeaderText="def" />
      <asp:BoundField DataField="hij" HeaderText="hij" />
      <asp:BoundField DataField="xyz" HeaderText="xyz" />
      <asp:BoundField DataField="eee" HeaderText="eee" />
      <asp:BoundField DataField="era" HeaderText="era" />
      <asp:BoundField DataField="nai" HeaderText="nai" />
      <asp:BoundField DataField="fac" HeaderText="fac" />
      <asp:TemplateField>
            <ItemTemplate>
                <div runat="server" style="visibility:hidden" id="hideme">
                    <asp:Label ID="lbllunch" runat="server" Text='<%# Eval("hij") %>' />
                    <asp:Label ID="lbllunchoverage" runat="server" Text='<%# Eval("xyz") %>' />
                    <asp:Label ID="lbleee" runat="server" Text='<%# Eval("eee") %>' />
                    <asp:Label ID="lblera" runat="server" Text='<%# Eval("era") %>' />
                    <asp:Label ID="lblnai" runat="server" Text='<%# Eval("nai") %>' />
                    <asp:Label ID="lblfac" runat="server" Text='<%# Eval("fac") %>' />
                </div>
            </ItemTemplate>
      </asp:TemplateField>
    </Columns>
</asp:GridView>

EDIT I added the .Visible command to my page load event (where I always hide anything on my page) like so:

protected void Page_Load(object sender, EventArgs e)
{
    hideme.Visible = false;
    /More here
}

If you want to hide template field column why you are adding it to markup. Yes if you keep style="visibility:hidden" it will show blank column only because item template still exists as column.

My suggestion for you is if dont need column dnt add markup.

You can hide the column in DataBound event of gridview.

protected void GridView_DataBound(object sender, GridViewRowEventArgs e)
{    
    GridView.Columns[8].Visible = false;       

}

Since hideme is inside the GridView TemplateField, you can't access it in Page_Load method, however you can access it in GridView1_RowDataBound method as below

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // find the hideme div
        HtmlGenericControl div = (HtmlGenericControl)e.Row.FindControl("hideme");

        // set the visible property
        div.Visible = false;
    }
}
