Setting a Button Cell

A button cell displays a rectangular button (with the word Button by default unless you specify otherwise) that behaves like a button control. You can specify the text for that button or you can substitute the entire graphic image. You can also specify text to appear underlined and blue, as a hypertext link would appear. The default appearance and the three possible alternatives are shown in this figure.

Appearances of Button Cell Types

To create a cell that acts like a button, follow this procedure.

For details on the properties and methods for this cell type, refer to the ButtonCellType class in the Assembly Reference.

Using Code

  1. Define the button cell type by creating an instance of the ButtonCellType class and specify whether it is push button, image button, or link button.
  2. Specify the properties of the button by setting the properties of that instance. Specify the text in the button or an image to use.
  3. Specify the command to execute when the button is selected.
  4. Assign the type to a cell (or cells).
  5. Use the ButtonCommand event to respond to the selected button. 

Example

In this example, create a button with text in the first cell, a button with a stored image in the cell diagonally below that, and a button with link text in the one diagonally below that. These are identical to those pictured in the figure (except for placement). Use the ButtonCommand event to respond to the selected button.
