eXontrol Software - Skinable Tree ActiveX, NET Control

Use the BackColorHeader and ForeColorHeader properties to customize the control's header. Use the HeaderVisible property to hide the control's header. Use the HeaderHeight property to specify the height of the control's header bar. Use the BackColor property to specify the control's background color. Use the BackColorLevelHeader property to specify the background color of the header when it displays multiple levels. Use the BackColorSortBar property to specify the background color of the control's sort bar.

The following VB sample changes the visual appearance for the control's header. Shortly, we need to add a skin to the Appearance object using the Add method, and we need to set the last 7 bits in the BackColorHeader property to indicates the index of the skin that we want to use. The sample applies the "" to the control' header bar:

With Tree1
    With .VisualAppearance
        .Add &H24, App.Path + "\header.ebn"
    End With
    .BackColorLevelHeader = RGB(255, 255, 255)
    .BackColorHeader = &H24000000
End With

The following C++ sample changes the visual aspect of the control' header bar:

#include "Appearance.h"
m_tree.GetVisualAppearance().Add( 0x24, COleVariant(_T("D:\\Temp\\ExTree.Help\\header.ebn")) );
m_tree.SetBackColorHeader( 0x24000000 );

The following VB.NET sample changes the visual aspect of the control' header bar:

With AxTree1
    With .VisualAppearance
        .Add(&H24, "D:\Temp\ExTree.Help\header.ebn")
    End With
    .Template = "BackColorHeader = 603979776"
End With

The 603979776 value indicates the &H24000000 in hexadecimal.

The following C# sample changes the visual aspect of the control' header bar:

axTree1.VisualAppearance.Add(0x24, "D:\\Temp\\ExTree.Help\\header.ebn");
axTree1.Template = "BackColorHeader = 603979776";

The 603979776 value indicates the 0x24000000 in hexadecimal.

The following VFP sample changes the visual aspect of the control' header bar:

With thisform.Tree1
    With .VisualAppearance
        .Add(36, "D:\Temp\ExTree.Help\header.ebn")
    EndWith
    .BackColorHeader = 603979776
EndWith
