ASP.NET gridview delete button

You need to handle the  OnRowDataBound event of gridview manually. like
<asp:GridView ID="GridView1" runat="server"
            .. OnRowDataBound="GridView1_RowDataBound">

Now, in code behind,you can write

protected void GridView1_RowDataBound(object sender,
        System.Web.UI.WebControls.GridViewRowEventArgs e)
    {
        if ((e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton selectButton = (LinkButton)e.Row.FindControl("LinkButtonSelect");
            if (selectButton != null)    // YOUR Logic to display
                selectButton.Visible = false;
          }
    }
