Example
The following snippet shows how to use many of the different properties provided by the UltraExpandableGroupBox to customize it's appearance.

Imports Infragistics.Win

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    ' Make sure that the UltraExpandableGroupBox is expanded.
    Me.UltraExpandableGroupBox1.Expanded = True

    ' Set custom images for the expansion indicator when the control is collapsed and expanded.
    Me.UltraExpandableGroupBox1.ExpansionIndicatorCollapsed = Bitmap.FromFile("myCollapsedImage.bmp")
    Me.UltraExpandableGroupBox1.ExpansionIndicatorExpanded = Bitmap.FromFile("myExpandedImage.bmp")

    ' Prevent the expansion indicator from drawing a focus rectangle when the control has focus.
    Me.UltraExpandableGroupBox1.ShowFocus = False

    ' Allow the elements in the header to hottrack.
    Me.UltraExpandableGroupBox1.HotTracking = True

    ' Make the caption red when the header is being hottracked.
    Me.UltraExpandableGroupBox1.HeaderHotTrackingAppearance.ForeColor = Color.Red

    ' Ensure that the caption is not bold when the control is collapsed.
    Me.UltraExpandableGroupBox1.HeaderCollapsedAppearance.FontData.Bold = DefaultableBoolean.False

    ' Make the caption bold when the control is expanded.
    Me.UltraExpandableGroupBox1.HeaderExpandedAppearance.FontData.Bold = DefaultableBoolean.True

End Sub
using Infragistics.Win;

private void Form1_Load(object sender, System.EventArgs e)
{
	// Make sure that the UltraExpandableGroupBox is expanded.
	this.ultraExpandableGroupBox1.Expanded = true;

	// Set custom images for the expansion indicator when the control is collapsed and expanded.
	this.ultraExpandableGroupBox1.ExpansionIndicatorCollapsed = Bitmap.FromFile( "myCollapsedImage.bmp" );
	this.ultraExpandableGroupBox1.ExpansionIndicatorExpanded  = Bitmap.FromFile( "myExpandedImage.bmp" );

	// Prevent the expansion indicator from drawing a focus rectangle when the control has focus.
	this.ultraExpandableGroupBox1.ShowFocus = false;

	// Allow the elements in the header to hottrack.
	this.ultraExpandableGroupBox1.HotTracking = true;

	// Make the caption red when the header is being hottracked.
	this.ultraExpandableGroupBox1.HeaderHotTrackingAppearance.ForeColor = Color.Red;

	// Ensure that the caption is not bold when the control is collapsed.
    this.ultraExpandableGroupBox1.HeaderCollapsedAppearance.FontData.Bold = DefaultableBoolean.False;

	// Make the caption bold when the control is expanded.
	this.ultraExpandableGroupBox1.HeaderExpandedAppearance.FontData.Bold = DefaultableBoolean.True;
