PB Controls

This repository contains a library of .NET user controls that I'm gradually building up as I work on other projects. Currently, there are two controls in the library: EditableListBox and HTMLRenderer.

EditableListBox

EditableListBox is intended to be an intuitive, editable ListBox control.

Edit mode is accessed by double-clicking on the control or pressing Enter when an item is selected. Once you're in edit mode, the up and down cursor keys can be used to cycle through the different items without committing any changes that are made. Tab and Shift+Tab can be used to cycle through the items, committing any changes that are made as you go along. Pressing Enter will commit changes and leave edit mode. Pressing Esc or simply navigating away from the edit region will leave edit mode without committing changes.

Programmatic interaction with the listed items is done through the public Items property. The programming interface is modelled on that exposed by the .NET ListBox control from System.Windows.Forms.

HTMLRenderer

HTMLRenderer is an HTML+CSS document renderer. Because it is simply a wrapper for the native WebBrowser control, it falls prey to the vagaries of the version of Internet Explorer that happens to be installed on the end user's machine.

Three methods are provided for rendering documents:

• void RenderURL(string) renders the document located at the supplied URL.
• void RenderFile(string) renders the document located at the supplied local file path (UNC paths are not supported).
• void RenderMarkup(string) renders the document markup as supplied in the argument.

In addition, two methods are provided to support communication between the rendered document and the hosting application:

• object CallFunction(string, object[]): Calls the script function specified by the first argument, passing the second argument as arguments and returning any return value.
• void AddCallback(Object): Adds the supplied object to the rendered DOM as window.external.
