How to manage cells

Starting from version 8 of the control, you have the opportunity to add as many cells you want to the button surface, both at design-time, through 3D Button Visual Editor, and at runtime through the CellsManager property (that internally implements the CellsManager COM object).

Each single cell can have the following features:

Solid background with border and alpha channel transparency support

Fully configurable caption text

Picture for control's normal and disabled states with alignment and alpha channel transparency support

Dedicated Click event (CellClick)

Let's see how to create our cells at Design-time:

Inside 3D Button Visual Editor, click the "Manage Cells" button as shown below

The cells management User Interface will appear as shown below: at any time you can go back to the standard user interface pressing the "Manage Control" button; as you can see, most of the cells management User Interface is disabled: the first thing to do is to press the "Add" button to add a new cell.

After pressing the "Add" button, a dialog box will require to identify the new cell with a numerical UniqueID (Unique IDentification number): this UnqiueID will be used at runtime to identify existing cells from each other; as you can see on the screenshot below, the User Interface will suggest you the UniqueID: you are in any case free to assign to the new cell the UniqueID you prefer. Pressing the "OK" button will create the new cell and will add it to the cells listbox.

You can now add as many cells as you need and then change the respective settings as explained on the sections below.

General settings

Actually there is no limit to the number of cells you can create inside a control (apart from your PC memory and resources) ; on the screenshot below, you can see that 4 cells have been created and listed inside the white listbox: note that the visible settings are relative to the cell selected inside the listbox: changing the selected cell will cause the various settings to be automatically updated and the Text and Pictures tabs will change their label in order to remember you which of the available cells is under editing.

Note: The image below has hot links to take you to explanations of the various controls: the property/method on the right column can be used at runtime.

Item name	Description	Corresponding property/method
Unique IDs listbox	Contains the list of the available cells Unique IDs	CellsManager.GetCount and CellsManager.GetCellUniqueID methods
"Add" button	Creates a new cell	CellsManager.AddCell method
"Delete" button	Deletes the selected cell	CellsManager.DeleteCell method
Visible	Sets/resets the selected cell visibility	CellsManager.Visible
Position in % X	The horizontal cell position expressed in percentage of the control width	CellsManager.AddCell, CellsManager.SetCellPos and CellsManager.GetCellPos methods
Position in % Y	The vertical cell position expressed in percentage of the control height	CellsManager.AddCell, CellsManager.SetCellPos and CellsManager.GetCellPos methods
Size in % Width	The cell width expressed in percentage of the control width	CellsManager.AddCell, CellsManager.SetCellSize and CellsManager.GetCellSize methods
Size in % Height	The cell height expressed in percentage of the control height	CellsManager.AddCell, CellsManager.SetCellSize and CellsManager.GetCellSize methods
"Apply" buttons	Apply the respective settings
Background transparent factor	Applies alpha channel transparency to the cell background color (if any)	CellsManager.BackTranspFactor
Background color	Applies a color to the cell background: if no color is applied (situation represented with the symbol inside the color box) the cell background will result completely transparent	CellsManager.BackColor
Border width	If set to 1 or higher, adds a border line to the cell	CellsManager.BorderWidth
Border color	Applies a color to the cell's border (if any): the default color is black	CellsManager.BorderColor
Change buttons	These buttons will open the color choice dialog box for the corresponding property.

At runtime you can also:

retrieve the total number of available cells using the CellsManager.GetCount method and the UniqueID for each of them using the CellsManager.GetCellUniqueID method.

understand if a cell with a certain UniqueID exists using the CellsManager.FindCell method.
