ToolPanelView is not hiding in crystal report

I have the  crystal report 2008 with service pack 6

I don't want to display the yellow highlighted tool panel as in the attached screenshot.

I have set the following properties from my code.But nothing works out.Please need suggestion.

                CrystalReportViewer1.ToolPanelView = CrystalDecisions.Web.ToolPanelViewType.None;

                CrystalReportViewer1.EnableParameterPrompt = false;

                CrystalReportViewer1.HasToggleGroupTreeButton = false;

                CrystalReportViewer1.HasToggleParameterPanelButton = false;   

Thanks,

Usha
