Show Hide ASP.Net ImageButton inside GridView based on condition using C#

Hi,

I have entered this condition in my dataset

1. when the value of message is equal to "1" it is not possible to continue working on this webpage.
2. when the value of message is equal to "0" it's possible to continue but it's not possible to edit the gridview data.

           if (message == 1)
            {
                Page.ClientScript.RegisterStartupScript(this.GetType(), "Alert", "alert('test msg 1');window.location='Default.aspx';", true);
                return null;
            }
            else if (message == 0)
            {
                Page.ClientScript.RegisterStartupScript(this.GetType(), "Alert", "alert('test msg 2');", true);
                btrila.Visible = false;
                btnreset.Visible = true;
                return dsProducts;
            }
            else
            {
                return dsProducts;
            }

when the value of message is equal to "0" I need hide or disable the button below for edit the gridview data

<ItemTemplate>
    <asp:ImageButton ID="btnedit" runat="server" CommandName="Edit"
        ImageUrl="/aspnet/img/edit_icon.gif" ToolTip="Edit" />
</ItemTemplate>

I have tried this solution in RowDataBound without success because the "btnedit" is always hidden.

Any help would greatly appreciate.

Thank you.

    protected void gvProducts_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (e.Row.DataItem != null)
            {
                if (btnreset.Visible == true)
                {
                    gvProducts.Columns[2].Visible = false;
                }
                else
                {
                    gvProducts.Columns[2].Visible = true;
                }
            }
        }
    }
