Nevron Diagram for .NET Q1 2008 - Released

nevron — Wed, 11 Jun 2008 14:16:00 GMT

Nevron Diagram has been designed from the ground up to meet a vast number of customization and extensibility requests. Built on top of the solid Model - View - Controller architecture it will provide your applications with consistent, intelligent and powerful diagramming abilities. Nevron Diagram for .NET is a unique component, since it integrates state-of-art vector and raster 2D graphics technologies and wraps them in an easy to use - yet completely customizable framework. As a result your applications can easily reuse it to instantly gain significant advantage in visual impact and intelligence. Following is a list of the new features introduced in this release:

Support for inward–outward port connections.
In this release we have implemented support for inward-outward ports. This feature lets you interactively glue an outward port to inward port. When an outward port of a shape is connected to an inward port, the shape will translate and rotate together with the shape owning the inward port. The translation aims to match the outward port location to the inward port location. The rotation aims to match both ports direction angles. For each type of port we have provided an extensive set of predefined modes in which a port can automatically determine its direction angle. Custom (user specified) direction angles are supported by all ports. This feature is extremely useful for interactive construction of connected shapes structures without edges. For example: in a floor plan diagram you can have a table with 4 inwards ports designated for the possible places where chairs can be placed. Chairs can have a single outward port. The placement of the chairs around the table is then a matter of simple drag and drop – Nevron Diagram will perform the snapping and glueing of the chairs to the table for you. When you move, rotate or resize the table the chairs will stay on their places.

Powerful support for graph, tree and cells layouts.
In this release we have added enterprise quality support for automatic layouts. The layouts are generally grouped in the following categories:

Graph Layouts – perform automatic arrangement of graph vertices and edges. Included the following layouts:
Force Directed Layouts - barycenter, spring and symmetrical. The implementation provides supports for lots of supplemental data provided on per edge and vertex basis. It addresses issues like magnetic fields, gravity force and vertex overlapping. The performance is significantly optimized due to the use of local temperatures. The overall quality of drawing is also improved because of the used global cooling method. It is suitable for any type of graph. Produces straight line graph drawings.
Layered Graph Layout – represents a classical implementation, which layouts a graph in layers. The layout addresses issues like crossing and bending minimization. It is suitable for any type of graph. Produces polyline graph drawings.
Orthogonal Graph Layout – represents a layout, which draws a graph only with horizontal or vertical line segments. The layout addresses issues like crossing minimization, bends minimization and overall compactness of the drawing. It is suitable for any type of graph. Produces orthogonal graph drawings.
Radial Graph Layout - represents a layout, which draws a graph in radial circles. It is suitable for any type of graph. Produces straight line graph drawings.
Tree Layouts – perform automatic arrangement of tree vertices and edges
Layered Tree Layout – layouts a tree in layers. The layout addresses the breadth compaction of the drawing. Produces straight line and orthogonal tree drawings.
Compact Depth Tree Layout – layouts a tree with minimal depth. The layout also addresses the breadth compaction of the drawing. Produces straight line and orthogonal tree drawings.
Tip Over Tree Layout - layouts a tree by placing children in either a row or a col. The row column children placement is controlled on a per vertex basis. Addresses the overall compaction of the drawing. Produces orthogonal tree drawings.
Balloon Tree Layout – layouts the tree in by placing the vertex children in a circular fashion. Addresses the overall compaction of the drawing. Produces straight line tree drawings.
Cell Layouts – perform automatic arrangement of the vertices of a graph
Stack Layout - represents a directed constrained cells layout, which stacks the cells in horizontal or vertical order. Depending on the layout direction the layout is constrained by either width or height.
Flow Layout - represents a directed constrained cells layout, which arranges the cells in horizontal or vertical lanes.
Dock Layout – represents space eating cells layout, which places vertices at per-vertex specified docking areas of the currently available layout area. Table Layout - represents a directed constrained cells layout, which arranges cells in a tabular manner.

Dynamic image map in AJAX mode
In Q1 2008 Nevron web components now support a dynamic image map that can be automatically updated at the client on every callback. The developer has control over when the image map is generated when is and updated on the client. The dynamic image map allows client side filtering of mouse events and prevents unnecessary callbacks for server side hit testing.

Controller-Tools Architecture in AJAX mode
Controller and tools are added to the Nevron client side JavaScript framework. All mouse events are now processed by the controller, which allows for implementing complex mouse handling logic and combining callback event processing with pure client side event processing.

New AJAX tools
Based on the controller-tools architecture, the following tools were added: - Click, double click, mouse down, mouse up, mouse move, mouse over and mouse out callback tools – intercept the mouse events and route them to the server for processing; - Dynamic cursor tool– changes the mouse cursor over interactive visual elements; - Redirect tool– redirects the browser to a specified URL when interactive visual elements are clicked; - Tooltip tool– displays tooltips over interactive visual elements.

Print Manager for Web Forms
None of the most popular web browsers is capable of printing really large images. Nevron .NET Vision Q1 2008 introduces a new HTTP handler that generates HTML, suitable for printing.

Future Improvements
The following list includes the improvements currently being developed in Nevron Diagram. Since they are beyond the scope of a single quarterly release, they will be embedded in the diagram when completely tested and implemented.

Pages
The diagram component will support pages. Each page will support different logical and display units, layers etc. The page will be controlled by a formula sheet.
Formula Shapes
Nevron diagram will support formula shapes. More details on this feature will be published additionally.

Q2 2007 introduces:

AJAX Support for Web Forms
Nevron Chart for .NET Q2 2007 now supports ASP.NET 2.0 AJAX 1.0. Nevron web controls allow AJAX callback handling of the following mouse events: click, double click, move, down and up. Also, the web controls can be forcibly refreshed at client-side and auto-refresh feature is available.

New Charting Types
Triangulated Surface series - this charting type can display a set of points with X, Y and Z coordinates as a 3D surface. In contrast to the Mesh Surface chart, the Triangulated Surface doesn't require the points to be ordered in a network. The control creates a triangular network automatically.

Improved Grid Surface and Mesh Surface
Grid Surface and Mesh Surface series now support smooth shading.

Data Binding with Custom Data Sources
The chart now supports data binding with custom data sources that implement the IBindingList and (optionally) the ITypedList interfaces.

Gauges for .NET
The component introduces new linear and radial gauge panels allowing you to display virtually any linear or radial gauge. Gauge features include multiple indicators, multiple gauge axes, intelligent gauge scale decorations and many more. The gauges in Nevron Chart for .NET use extensively the Nevron Smart Shape technology as well as the Nevron Scale technology. Developers familiar with chart scale programming will find the new gauge axis API very easy and straightforward.

What's New in Nevron User Interface for .NET Q2 2007

Q2 2007 introduces:

Gallery Panel
The NGalleryPanel is an item-container control which mimics the Microsoft® Office 2007 galleries. 4 different types of item layout are provided so that the panel may be used as an extended list-box or list-view. Based on the Nevron generic UI element, the NGalleryItem component is highly customizable in each aspect of visual representation, including rich texts, alpha-blended images, custom item size, etc.

ListView
The NListView extends the standard Windows Forms ListView control and adds missing features like complete control over header and header items, alternating rows, column sorting, sorted column glyph, sorted column shading, custom scrollbars, etc.

Rotator
The NRotator is a very useful control which brings the popular "Rotator" feature from ASP.NET to your Windows Forms. The control contains a collection of frames where each frame is described by a generic UI element providing complete control over visual appearance, image and text. The well-designed set of properties will enable you with fine-tune control over frame duration, animation speed, animation direction plus much more.

Command Bars – ImageTextRelation
Provides complete control over the image and text entities of an NCommand object by specifying the ImageTextRelation property of its parent.

Task Dialog - Radio Buttons
The NTaskDialog is further extended and now it supports a set of radio-buttons for richer user experience. The radio buttons are layouted just below the Content section of the dialog.

Docking Panels - Sizing Restrictions
Nevron Docking Panels are now enabled with sizing restrictions in floating state. You may alter the MinimumSize, MaximumSize and Sizable properties of a floating container directly.

Docking Panels - Visual Tab Navigation
Nevron Docking Panels are the only Docking Library which enables you with the advanced CTRL+TAB visual navigation found in Microsoft® Visual Studio 2005. Pressing Ctrl+Tab will display a NPopup containing two gallery panels - one containing all active docking panels and one containing all active documents. Optionally this feature may be turned on and off via the VisualTabNavigation property of an NDockManager. You may also change the shortcut which triggers the pop-up.

Navigation Pane - Expand/Collapse
The NNavigationPane is extended with the Collapse/Expand feature found in Microsoft® Office 2007. By clicking the button on the caption of the pane you toggle its state. When the pane is collapsed you may display the currently active band by clicking in the area below the caption and above the buttons stack.
