Our third new Toolkit control is the KryptonRichTextBox. As we have only just added the KryptonTextBox it makes sense to also add the rich version as well. The implementation works in the same way as previously, with a real WinForms RichTextBox embedded inside a Krypton Toolkit control.

Here it is in full techno-color…

The bottom instance has been given some RTF by assigning to the KryptonRichTextBox.Rtf property. Hence it shows using a variety of font settings and colors and also explains why it is not drawing in the same anti-aliased way as the other instances. I just creating some text in WordPad and exported it to a .rtf file. Then in the constructor of the samples I load the file into the control instance via the Rtf property.

I have exposed almost all the properties, methods and events as are present on the actual underling control and so you should be able to use it as a simple plug replacement for the original RichTextBox. But there might be some circumstances that you want direct access to the embedded control. You can do this using the KryptonRichTextBox.RichTextBox property.

For example the drag and drop set of events cannot be exposed via the actual Krypton control because that would be entirely to confusing. But you can hook into them in your code using KryptonRichTextBox.RichTextBox.DragEnter.
