In this release Nevron User Interface for .NET includes a powerful new control named NTreeList. The control is based on the NTreeViewEx and extends it by adding list-view functionality. This combination allows for complex data-related tasks like grouping, sorting, binding, etc. The control appearance and functionality is highly customizable. Following are the some of the major features of the control:

• Freezable list view columns
  
  You can choose some columns to be displayed regardless how the user scrolls horizontally. This is feature is very useful when you need to make sure that important data is always displayed.
  
  
• Binding to a Data Table
  
  This feature allows you to import the NTreeListData from a DataTable object, as well as to implement custom data import.
  
  
• Extensible row filtering
  
  You can combine several types of predefined filters to selectively display rows in the list.
  
  
• Sorting
  
  The controls allows you to sort by rows with the same tree depth as well as to sort recursively (that is sort the children of these nodes as well).

• Redesigned Scale Model
  
  The Axes of Nevron Chart now employ a declarative scale model to describe the axis scale, scale decorations and wall decorations. This is combined with a powerful set of scale configurators that can be used to describe and extend any type of scale. Following is a list of the major advantages of this model:
  • Label Fitting - the scale can now automatically detect and resolve label overlapping - this is implemented in both 2D and 3D.
    
    
  • Better Date Time Support - you can now specify non-regular time units (e.g. units that cannot be expressed through milliseconds and are dependent on some reference date). The month, quarter and year are example of such units.
    
    
  • Distance Based Scale Decoration - this is the ability to control the distance between scale decorations (ticks, labels etc) depending on the scale size in device units - this feature automatically reduces / increases the number of ticks and labels on the scale depending on the size of the chart. Smaller charts will be less decorated which improves the chart readability.
    
    
  • Interlace and Sampled Stripes - this feature allow you to dynamically highlight ranges of data on the chart.
    
    
  • Scale Sections - Scale sections allow you to alter the appearance of different scale elements if they fall in a specified range. This allows you to visually highlight important ranges of data that the user has to pay special attention to.
    
    
  • Custom scale programming - you can now modify the standard defined axis scales in any way you see fit or create custom ones.
    
    
  
  
  
• Redesigned Axis Positioning
  
  The Axes in Nevron Chart now use anchors to attach to different places in the chart. There are two types of anchors - Dock and Cross anchors.
  Dock anchors allow you to dock the axis to one of the 12 edges of a 3D cube. Each edge is called a zone. This type of docking allows you to stack axes on the sides of the chart without overlapping.
  Cross axis anchors allow you to position the axes to cross another axis either at a certain value or at a percentage of the crossed axis length.
  
  
• Improved Axis Paging
  
  The component has improved axis paging supporting both numeric and date time data. This is integrated with automatic scrolling and automatic small step scroll size calculation.
  
  
• Better Scalability
  
  The Series in the component were extended to support the NLength format. As a result you can now specify for each series how the size that is not scaled on the axes should be treated. For example you can have a point series with data points 10px wide and tall or 10 percent wide and tall from the chart area. In the first case points will have the same size as the chart resizes, whereas in the second they will follow the dimensions of the chart.
  
  
• Guidelines
  
  Guidelines allow you to align panels (charts, legends, titles etc.) either vertically or horizontally. This feature is very useful when you create multiple charts.
  
  

Planned Improvements
Although in this release there are no major changes in the diagram, there are huge improvements, which Nevron is currently developing for this component. Since they are beyond the scope of a single quarterly release, they will be embedded in the diagram when completely tested and implemented.
