Panel Property

Gets a reference to UltraExpandableGroupBoxPanel used by the UltraExpandableGroupBox. If you are adding controls to the UltraExpandableGroupBox at runtime you need to add them to the Controls collection of this object, not to the Controls collection of the UltraExpandableGroupBox.

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property Panel As UltraExpandableGroupBoxPanel

C#

public UltraExpandableGroupBoxPanel Panel {get;}

Remarks

The UltraExpandableGroupBox can only have one child control; an UltraExpandableGroupBoxPanel. All other controls contained in the groupbox should be added to the Controls collection of the Panel. Any attempt to add a control directly to the UltraExpandableGroupBox will result in an exception being thrown.

Example

This snippet demonstrates how you can add child controls to the UltraExpandableGroupBox. Note that you do not add them directly to the Controls collection of the UltraExpandableGroupBox, rather, you add them to the Controls collection of the Panel property.

Visual Basic

Private Sub LoadChildControls()

    ' Get a reference to the UltraExpandableGroupBoxPanel in the groupbox.
    Dim panel As Infragistics.Win.Misc.UltraExpandableGroupBoxPanel = Me.ultraExpandableGroupBox1.Panel

    ' Create child controls and add them to the panel.
    '
    Dim btn As New Infragistics.Win.Misc.UltraButton()

    panel.Controls.Add(btn)

    btn.Text = "Click Me"
    btn.Size = New Size(75, 30)
    btn.Location = New Point(210, 190)

    Dim txt As New Infragistics.Win.UltraWinEditors.UltraTextEditor()

    panel.Controls.Add(txt)

    txt.Text = "Enter some text..."
    txt.Size = New Size(200, txt.Size.Height)
    txt.Location = New Point(panel.Width / 2 - txt.Width / 2, 80)

End Sub

C#

private void LoadChildControls()
{
	// Get a reference to the UltraExpandableGroupBoxPanel in the groupbox.
	Infragistics.Win.Misc.UltraExpandableGroupBoxPanel panel = this.ultraExpandableGroupBox1.Panel;

	// Create child controls and add them to the panel.
	//
	Infragistics.Win.Misc.UltraButton btn = new Infragistics.Win.Misc.UltraButton();

	panel.Controls.Add( btn );

	btn.Text = "Click Me";
	btn.Size = new Size( 75, 30 );
	btn.Location = new Point( 210, 190 );
	
	Infragistics.Win.UltraWinEditors.UltraTextEditor txt = new Infragistics.Win.UltraWinEditors.UltraTextEditor();

	panel.Controls.Add( txt );

	txt.Text = "Enter some text...";
	txt.Size = new Size( 200, txt.Size.Height );
	txt.Location = new Point( panel.Width / 2 - txt.Width / 2, 80 );
}
