Gets or sets the value indicating whether the ToolBase instance represents the beginning of a visual grouping of tools.
Syntax
'Declaration
 
Public Property IsFirstInGroup As Boolean
public bool IsFirstInGroup {get; set;}

Property Value

True if the current tool instance represents the beginning of a group of tools; False otherwise.
Exceptions
ExceptionDescription
System.NotSupportedExceptionThe property is modified at design-time for a tool in an UltraToolbarsManager defined on a base Form or UserControl. Inherited tools must be modified at run-time or at design-time through the designer of the Form or UserControl they were created on.
Remarks

When this property is set to True, a visual separator is shown before this tool to indicate a new grouping.

Example
The following code creates 2 toolbars and a button tool. It adds an instance of the button tool to each toolbar. It then sets some shared properties on the tool which will affect both tool instances, and then sets some instance properties which just affects one of the instances.
