Project Description

Simple HexControl (HexView) is a classic Windows Forms control. It implements a hexadecimal view of bytes with grouping. It's blazing fast, renders only visible frame of a window and supports of painting the individual groups of bytes without the total window being redrawn.

Source code

Source code for the project have been released. Added a new distribution with sample Windows Forms application. You can find code here:



- Supports vertical and horizontal scrolling
- Supports auto-scroll / auto hide scroll bars
- Renders only visible window frame
- Can update individual byte change
- Supports any type of fonts
- Less intense calculations due to bytes block measurement / rendering


HexControl is scrollable composite Windows Forms control. Control logic is divided into presentation logic, model, and some simple code to reflect model changes to presentation control (M-V pattern), skipping controller logic totally, because controller part (events, subscriptions, updates) will be taken totally by the .NET Framework.

In-depth description of implementation, design and architecture:


Rendering of the data is controlled by the rendering options you provide for the control. You can change grouping of the bytes by setting HexControl properties in Appearance section:

- BytesPerColumn
- ColumnPerRow




Alternative control is very ugly, so ugly that I couldn't place it on a main page. Feel the difference.
