기능

New MongoDB Data Source

• The Data Source Configuration Wizard allows you to connect and retrieve data from a MongoDB database. The MongoDB data source allows you to select the desired database name, document collection name and define the appropriate server-side filtering clause.

Data Grid

• Search Boxes within Column Headers
  • Column headers can now display search boxes. Users can click a search icon and enter filter criteria within column headers.
• TileView - Conditional Formatting
  • The Tile View now offers Conditional Formatting support. You can highlight tiles and individual tile elements (fields) based on specified criteria without writing a single line of code. Tiles can be highlighted using icons and predefined color scales.
• Filter Panel - MRU Filters
  • The Filter Panel displays separate tokens with filters for each column. In this version, the MRU filter list (most recently used filters) has been incorporated and the new Filter Panel has been enabled by default.
• Filter Editor - Custom Expressions
  • Custom expressions that cannot be converted into Filter Editor nodes are now displayed within text fields. This ensures no expressions are lost. End-users can add custom expressions at runtime using a context menu.
• Unbound Column Enhancements
  • You can now explicitly set an unbound column type. You can also specify previously unavailable types, such as TimeSpan or DateTimeOffset.
• New Appearance Options for Detail Tabs
  • The new DetailTabStyle event allows you to customize captions, images, colors and font settings for detail tabs. A 'RefreshDetailTab(rowHandle)' method has been added to update detail tabs at runtime. You can also enable the 'OptionsView.AllowHtmlDrawDetailTabs' option to use HTML-inspired tags.

Charting

• Memory Optimization and New Data Adapters
  • With this release, the WinForms Chart Control allocates less memory when used in data bound mode. This enhancement has increased the maximum number of visible data points for x86 apps without significant performance degradation (up to 20M).
  • The new data adapters (ISeriesAdapter and ISeriesTemplateAdapter) allow you to process complex data structures much faster. You can also implement a custom data adapter to process data as needed.

    • Start No Earlier Than.
    • Start No Later Than.
    • Finish No Earlier Than.
    • Finish No Later Than.
    • Must Start On.
    • Must Finish On.
  • Task constraints can be set if the data source contains corresponding data fields. Use the new ConstraintTypeFieldName and ConstraintDateFieldName properties to specify data field names.
