Presenter Features

Automatic view state synchronization
Presenter's Automatic state synchronization seamlessly saves the latest data state as users perform various data interactions. The data state - such as filtered columns, sorted columns and columns order - will be properly maintained as user navigates to different views.

High performance VirtualScroll technology
All built-in views in Presenter are powered with Virtual Scrolling, a technology that enables each view to display large dataset without performance hit. As a result, end user can enjoy smooth and consistent scrolling behavior regardless of the total number of objects and the rendering complexity.

Ultra fast data loading and fetching
Presenter is optimized for extremely heavy data usage with its data presenter manager concept. All data is fetched and aggregated in one centralized data source and distributed when requested - enabling Presenter to perform data operations quickly and efficiently, without bloating up resources consumption.

Client-side and server-side operations
Designed as an enterprise-ready data visualization component, Presenter offers the flexibility to choose the best data operation mode according to the usage and scenarios. Choose client-side operation to load all data to client-side which eliminates client-server roundtrip. When you're dealing with larger data, choose server-side operation for best performance as it loads smaller chunk of data when requested by the presenter.

Frozen column
Frozen column is one of the most innovative features in Grid Presenter. It lets users to freeze a number of columns from the left which will stay visible as user scrolls the viewport to the right direction.

Column ordering
It's possible to rearrange the column order in Grid Presenter. Simply click and drag on a column and drop it in between columns. Notice that Presenter will adjust its view automatically and move the entire column to the new location. Column rearranging can be used to change the grouping order by simply move the grouped columns inside the action box.

Multiple items selection
Presenter provides multiple items selection feature which is implemented consistently in all built-in presenters. You can select multiple items by using keyboard keys including combination of ctrl and shift key, or by using mouse and keys combination. Thanks to the automatic view state synchronization feature, all selected items will be persisted during view switching, enables user to easily work on selection.

When a column is hovered, click on the drop down arrow next to the column caption to show the action box, and then perform the desired data operation.

Unbound mode
In addition to its powerful data binding capability, Presenter is also designed to work in unbound mode and provides the flexibility to bind to any type of objects instead of data source controls, such as collection, arrays, generic lists and more. Its comprehensive client-side object model enables direct access over presenter's collection for manual item binding.

Customizable grid elements
Grid Presenter allows designers to completely change the styles and appearances through templates in Expression Blend, from alternating row style, row header, action box, loader style, to visual state styles.

Automatic and manual column generation
By default, Presenter automatically generates columns based on the given entity (datasource item). With automatic mode, basic metadata such as data type and caption text will be automatically assigned. The manual mode gives you total control to create your own column definitions.

Flexible row templating

Presenter's editing behavior is carefully designed based on extensive research in user's data editing processes to provide the best editing experience possible. It keeps track of current UI state and intelligently validates the next possible action. For example, when the presenter is in editing mode, clicking on column header won't invoke any data operations until the presenter has exited from editing mode.

Built-in data validation engine
High-quality data is very essential for mission-critical web applications. Understanding the need to provide the most accurate input, Presenter includes highly customizable input validation engine.
