How to remove Main Report button in crystal report viewer?

Question

How to remove this tab in crystal report viewer?

I have tried this. But not working.

public void HideTabs(CrystalReportViewer viewer)
        {
            foreach (Control control in viewer.Controls)
            {
                if (control is PageView)
                {
                    TabControl tab = (TabControl)((PageView)control).Controls[0];
                    tab.ItemSize = new Size(0, 1);
                    tab.SizeMode = TabSizeMode.Fixed;
                    tab.Appearance = TabAppearance.Buttons;

                }
            }
        }

Controls array not having any control.

Hi friend Sorry for taking time to give you the correct answer. The reason for your issue is you should call this code after you set the report source. If the report source is null as you said it has no controls and the your mathod throws an exception. So make sure that the report source is set before you call your method.

Sorry is an windows application

Nilanka Dharmadasa · Answer

Hi Kailash Anyway if your application is a windows one there is no such tab in the crystal report viewer. If your application is a web based one setting following property of crystal report viewer will hide the tab. protected void Page_Load(object sender EventArgs e) { CrystalReportViewer1.HasDrilldownTabs = false; } I hope I understood your code correctly. If you find my answer useful please tick ' Do you like my answer ' checkbox.
