Create hierarchical views of your data which users can collapse and expand; sort data by clicking column headers or filter data out of view. The simple, yet powerful grouping, sorting and filtering mechanisms are offered by the ICollectionView data source. With FlexGrid, filtering and grouping even work perfect together with large data sets.

In addition to databound support, FlexGrid also works great in unbound mode. Simply add rows and columns to the grid using familiar syntax from the WinForms version of the control. When unbound, the C1FlexGrid control stores data internally.

Editing in the C1FlexGrid is similar to editing in Excel. Pressing F2 or double-clicking a cell puts the grid into full-edit mode where pressing the cursor keys does not cause the editor to lose focus. Typing text directly into a cell puts the grid in quick-edit mode. The cell editor remains active until the user presses Enter, Tab, or Escape, or any arrow keys.

The FlexGrid control provides a GetPageImages method that breaks up the grid into a list of Visual Elements representing each page in a document which allows for printing in WPF with use of a PrintDocument. Rows are never cut in half on page breaks, and each page shows full column headers for best readability.

Freeze any number of rows and columns by simply setting the Rows.Frozen or Columns.Frozen properties. Frozen panes never scroll out of view.

FlexGrid has a rich selection model which includes the following selection modes: single cell, cell range, single row, row range, and list box. ListBox selection refers to an arbitrary set of non-continuous rows. You can extract a lot of useful information from the Selection including a collection of data items, or just the string values. You can easily monitor selections in the SelectionChanged event.

FlexGrid provides an easy way to apply simple formatting to a specific grid row or column. For example, you might want to highlight a column by applying a bold font and yellow background to it. This is possible because the row and column objects expose a complete collection of style properties for customizing the fonts and brushes used to render the grid. You can set these style properties in XAML or in code.

The C1FlexGrid control has AutoSizeRow and AutoSizeColumn methods that take into account the data currently visible. This can be done quickly and accurately.

FlexGrid for WPF shares the same codebase as FlexGrid for Silverlight, so they are 100% source-code compatible. This model enables easier development across both platforms because you can share a lot of the same code and develop applications for the web (Silverlight/XBAP) and desktop.
