Custom Controls

When writing your own custom controls that are working alongside the Krypton controls you may want to ensure that the look and feel of your custom control matches that of the Krypton components. There are two levels of integration that you can aim for. The first is to use the same palette of colors, font, widths and other metrics when drawing and sizing your custom control. This is the purpose of the Using PaletteBase article. Recovering these metrics is actually very simple and you can examine the Custom Control using Palettes sample project to see the principle in action.

Alternatively you might want to leverage the same rendering code that the Krypton Toolkit controls use. In this case follow the Using IRenderer article to understand how to render background, border and content elements within your custom control client area. Although a little more complicated this technique has the advantage of performing the hard work for you. You can use the renderer to draw vertical orientated text and elements with tiled images without the need to write the actual drawing code yourself.
