Use the BackColor and ForeColor properties to change the background and foreground colors for a specified file/folder. Use the Get method to get the collection of files/folders. Use the Folder property to specify whether the File object hosts a file or a folder. Use the SelBackColor property to specify the background color for selected items. Use the Ghosted property to change the item's appearance.

The following VB sample changes the background color for the item named "Temp":

With ExFileView1.Get(AllItems)("Temp")
    .BackColor = vbBlue
    .ForeColor = vbYellow
    .Bold = True
End With

The BackColor attribute is lost if the control is refreshed or if the Apply property is called. For instance, If you need a permanent background color for specified folders, you can add a new FileType object like in the following VB sample:

With ExFileView1.FileTypes.Add("Temp")
    .Folder = True
    .BackColor = vbBlue
    .ForeColor = vbYellow
    .Bold = True
    .Apply
End With

The following C++ sample changes the background color for the item named "Temp":

CFile1 file = m_fileview.GetGet( 1 /*AllItems*/ ).GetItem( COleVariant( "Temp" ) );
file.SetBackColor( RGB(0,0,255) );
file.SetForeColor( RGB(255,255,255) );
file.SetBold( TRUE );

The BackColor attribute is lost if the control is refreshed or if the Apply property is called. For instance, If you need a permanent background color for specified folders, you can add a new FileType object like in the following C++ sample:

#include "FileType.h"
#include "FileTypes.h"
CFileType fileType = m_fileview.GetFileTypes().Add("Temp");
fileType.SetFolder( TRUE );
fileType.SetBold( TRUE );
fileType.SetForeColor( RGB(255,255,255) );
fileType.SetBackColor( RGB(0,0,255) );
fileType.Apply();

The following VB.NET sample changes the background color for the item named "Temp":

With AxExFileView1.get_Get(EXFILEVIEWLib.TypeEnum.AllItems).Item("Temp")
    .BackColor = ToUInt32(Color.Blue)
    .ForeColor = ToUInt32(Color.Yellow)
    .Bold = True
End With

where the ToUInt32 function converts a Color expression to OLE_COLOR, 

Shared Function ToUInt32(ByVal c As Color) As UInt32
    Dim i As Long
    i = c.R
    i = i + 256 * c.G
    i = i + 256 * 256 * c.B
    ToUInt32 = Convert.ToUInt32(i)
End Function

The BackColor attribute is lost if the control is refreshed or if the Apply property is called. For instance, If you need a permanent background color for specified folders, you can add a new FileType object like in the following VB.NET sample:

With AxExFileView1.FileTypes.Add("Temp")
    .Folder = True
    .BackColor = ToUInt32(Color.Blue)
    .ForeColor = ToUInt32(Color.Yellow)
    .Bold = True
    .Apply()
End With

The following C# sample changes the background color for the item named "Temp":

EXFILEVIEWLib.File file = axExFileView1.get_Get(EXFILEVIEWLib.TypeEnum.AllItems)["Temp"];
file.BackColor = ToUInt32(Color.Blue);
file.ForeColor = ToUInt32(Color.Yellow);
file.Bold = true;

where the ToUInt32 function converts a Color expression to OLE_COLOR, 

private UInt32 ToUInt32(Color c)
{
	long i;
	i = c.R;
	i = i + 256 * c.G;
	i = i + 256 * 256 * c.B;
	return Convert.ToUInt32(i);
}

The BackColor attribute is lost if the control is refreshed or if the Apply property is called. For instance, If you need a permanent background color for specified folders, you can add a new FileType object like in the following C# sample:

EXFILEVIEWLib.FileType fileType = axExFileView1.FileTypes.Add("Temp");
fileType.Folder = true;
fileType.BackColor = ToUInt32(Color.Blue);
fileType.ForeColor = ToUInt32(Color.Yellow);
fileType.Bold = true;
fileType.Apply();

The following VFP sample changes the background color for the item named "Temp":

With thisform.ExFileView1.Get(1).Item("Temp") && AllItems
    .BackColor = RGB(0,0,255)
    .ForeColor = RGB(255,255,255)
    .Bold = .t.
EndWith

The BackColor attribute is lost if the control is refreshed or if the Apply property is called. For instance, If you need a permanent background color for specified folders, you can add a new FileType object like in the following VFP sample:

With thisform.ExFileView1.FileTypes.Add("Temp")
	.Folder = .t.
    .BackColor = RGB(0,0,255)
    .ForeColor = RGB(255,255,255)
    .Bold = .t.
    .Apply()
EndWith
