ColorTextBox is a .NET 2.0 User Control which was written from scratch and is meant as a replacement for the
TextBox control of the .NET class library.
ColorTextBox is a by-product of LMX-Editor, an Open Source XML editor I developed as part of my diploma thesis. Since I was very disappointed by the performance of the
RichTextBox control available in the .NET library (the standard
TextBox does not support colored text), I decided to write my own
ColorTextBox on which the aforementioned editor is based.
Using the code
ColorTextBox does not inherit from the abstract
TextBoxBase class of the .NET library, it was designed to be compatible with the default
TextBox implementation. So, if you're familiar with the usage of the standard
TextBox, you can use
ColorTextBox right away.
In fact, it should be no or little effort to replace
TextBoxes in existing applications with instances of the
ColorTextBox. If you develop under Visual Studio .NET 2005, you can use the Forms Designer to configure all relevant properties of the control.
Just look at the code provided in the example: it's a simple text editor which was built in about 30 minutes, and shows the most important features of the

As mentioned before, the
ColorTextBox control is the base for an Open Source XML editor I wrote, which includes features like syntax highlighting and folding. If you want to write your own code editing component, have a look at the complete source code at SourceForge, which contains a generic
CodeTextBox control which can be easily extended to support the mentioned features. Furthermore, the latest code for
ColorTextBox will always be available under the link above!
