SftBox/OCX 5.0 - Combo Box Control

SftBoxHeader.Image Property

Defines the graphic displayed in this column header.

Syntax

Get

Put

object

A SftBoxHeader object.

refImageObj

Defines the graphic displayed in this column header.

Comments

The Image property defines the graphic displayed in this column header.

All column header graphics (i.e. all bitmaps) must be the same size (height and width). The dimensions of the graphics are used to calculate the minimum required height for all column headers (and row/column header), so graphics and text are never clipped vertically. To change the size of all header graphics used, they must be removed first using the Headers.ClearImages method.

If the image object refImageObj defines a bitmap, the top, left pixel of the bitmap must contain the bitmap's background color. This color will be replaced throughout the bitmap with the actual background (see Bitmap Transparency).

To remove an individual header picture, set the property to Nothing (0, null, NULL).

The position of the graphic relative to the text component can be defined using the Header.ImageHAlign and Header.ImageVAlign properties.

Examples

VB.NET

    ItemIndex = AxSftBox1.Items.Selection
    If ItemIndex < 0 Then Exit Sub

    ' don't use images that are too large in the other areas
    Img = AxSftBox1.get_Cell(ItemIndex, 0).Image
    If Img.ActualHeight <= 20 And Img.ActualWidth <= 20 Then
        AxSftBox1.RowColumnHeader.Image = Img
        AxSftBox1.get_Header(1).Image = Img
    Else
        AxSftBox1.RowColumnHeader.Image.Clear()
        AxSftBox1.get_Header(1).Image.Clear()
    End If
