KryptonInputBox

The KryptonInputBox now uses the new KryptonInputBoxData API, to handle data.

Building the Toolkit

As of V90.00 support for longer path names will need to be enabled if you want to build the toolkit yourself. For more details on how to do this, please follow the instructions in the long path names configuration guide.

There are list of changes that have occurred during the development of the V80.00 version

Support for .NET Core 3.1 and .NET 5

As of V80.00, support for .NET Core 3.1 and .NET 5 has been removed due to their release cadences. It is strongly advised that you migrate your application to .NET 8, as the latest LTS version, or the slightly older .NET 6, if you require a more supported version. If you do not make these mitigations, the packages will fail to install when upgrading, if your project is configured to use either .NET Core 3.1 and .NET 5.

KryptonMessageBoxButtons

• https://github.com/Krypton-Suite/Standard-Toolkit/issues/728: Bring MessageBox States inline with latest .Net 6 by using a new KryptonMessageBoxButtons type, which is effectively the same as .NET 6 enum version of MessageBoxButtons but backward compatible with .NET Framework 4.6.x onwards.

Palette usages

• KryptonPalette has become KryptonCustomPaletteBase to better signify it's usage.
• IPalette has been removed, and the usage of PaletteBase throughout the toolkit is used; to ensure consistent usage.

Depreciation of KryptonManager.Strings

In a effort to support translations, KryptonManager.Strings is now obsolete. As such, the new KryptonLanguageManager will handle such strings.

=======

Known Issues & Workarounds

• #1109 - KryptonPropertyGrid 'jagged' text

  • Some controls can display Jagged text when drawing. (i.e. ComboBox contents / PropertyGrid / Extended controls ) This is due to the usage of the Legacy API Application.SetCompatibleTextRenderingDefault having a value of true. Please set it to false.

• #665 - Workaround add net48 or net481 to your <TargetFrameworks> if using .NET 8 or newer.

• .NET 6/7 Designer issues - If you are experiencing designer issues with your project, please refer to this for more information

• URGENT: If anyone experiences "Double events" such as the one found in issue #666 about double events, please can you report it ASAP, so that they can be investigated. Thanks!

Introduction

The Krypton Suite contains user interface components designed to make it quick and easy for developers to create professional looking applications. It provides the essential building blocks needed to create a consistent look and feel across all your products. You can use the built-in palettes to achieve the same appearance as industry standard applications such as Microsoft Office 2007/2010/2013 & Microsoft 365, Visual Studio 2010. Alternatively you can create your own custom palettes to create a completely unique user interface. The Krypton Suite consists of five products called Krypton Toolkit, Krypton Ribbon, Krypton Navigator, Krypton Workspace and Krypton Docking.

What is this Repository About?

• Modifications by Peter Wagner (aka Wagnerp), Simon Coghlan (aka Smurf-IV), Giduac, tobitege & Ahmed-Abdelhameed have been fixing and adding more capabilities to this toolkit.
• There is also an Extensions project, which takes these base controls and add more useful complete controls (Currently outside the scope of this help). To find out more about the Extended Toolkit, please visit the Extended Toolkit repository
• All .Net Versions from 4.8.2 are catered for (interim releases, i.e. releases in-between Long Term Support (LTS) versions of .NET will only be supported for the duration of that particular version, usually 24 months.)
• New versions of NuGet packages can be obtained via the Krypton Suite NuGet profile page, or via your package manager by searching Krypton..
• New, major versions are released annually, with patches if needed released throughout that period. Version 100 is expected to release in November 2025.
• For tips on how to build the toolkit for yourself, please read the following article.

Individual Components

Krypton Toolkit

The Krypton Toolkit provides a set of basic user interface components for free. You can distribute the signed Krypton Toolkit assembly without charge or royalty with your own products. The Krypton Toolkit is great resource for speeding up development of professional looking applications. It works in tandem with the MenuStrip, StatusStrip and ToolStrip controls that come with .NET Framework controls. Using the Krypton Toolkit you can create a great looking application in just minutes.

Krypton Ribbon

The Krypton Ribbon is designed to mimic the look, feel and operation of the ribbon control seen in the Microsoft Office 2007/2010/2013/365 applications such as Word and Excel. It provides advanced capabilities including the quick access toolbar, contextual tabs and auto shrinking groups. With rich design time support and sample code you can be up and running with the ribbon in no time at all. It integrates with the Krypton Toolkit architecture to ensure a consistent look and feel.

Krypton Navigator

The Krypton Navigator is a user interface control that provides the user with a variety of ways to navigate around a set of pages. Think of it as a traditional TabControl on steroids. It has many different modes of operation allowing you to achieve exactly the right operation for your application. It integrates with the Krypton Toolkit architecture to ensure a consistent look and feel.

Krypton Workspace

The Krypton Workspace allows a document area to be created that the user can customise by dragging and dropping pages into new positions. Similar to the Visual Studio document area but with far greater flexibility and functionality. Each cell within the workspace uses an instance of the Krypton Navigator allowing a wide range of options for organising and displaying pages. It integrates with the Krypton Toolkit architecture to ensure a consistent look and feel.

Krypton Docking

The Krypton Docking set of components allow the user to drag and drop docking pages into new locations in order to customise the organisation of the application content. It allows this in a way similar to that of Visual Studio 2008/2010. Each docking area uses an instance of the Krypton Workspace allowing a wide range of options for organising and displaying pages. It integrates with the Krypton Toolkit architecture to ensure a consistent look and feel.
