In this article I will explain with an example, how to hide Group Tree Panel in Crystal Reports. The Group Tree Panel can be hidden using a property of the Crystal Report Viewer control in Visual Studio.
 
 
Hide Group Tree Panel in Crystal Reports
The Group Tree Panel can be hidden by setting the ToolPanelView property of the Crystal Report Viewer control to None.

<%@ Register Assembly="CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"
    Namespace="CrystalDecisions.Web" TagPrefix="CR" %>

</head>
<body>
    <form id="form1" runat="server">
    <CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="true" ToolPanelView = "None" />
    </form>
</body>
</html>
 
In older version of Crystal Reports it can also be done from code behind using the DisplayGroupTree property of the Crystal Report Viewer control as shown below.
C#
CrystalReportViewer1.DisplayGroupTree = false;
 
VB.Net
CrystalReportViewer1.DisplayGroupTree = False
