- Data sorting, filtering and grouping
- Project template (data project/group title)

chart
New spline series
This version introduces a new spline chart type in Xamarin.Forms and native mobile chart library.
Point and segment shaders
v20.2 introduces point and segment shaders to Xamarin Forms and mobile chart libraries. This new feature allows you to define colors for series of points and line/surface segments based on data. You can use predefined shaders (such as , Each color or value range) or implement custom algorithms as needed.
Axis label format enhancement
Xamarin Chart View can now automatically format the date and time and number axis labels. This feature allows you to display extended information within the chart axis.
Data form
Layout enhancement
- The field editor can now span multiple rows (just use the RowSpan property of the DataFormItem class).
- The new DataFormView.EditorLabelHorizontalAlignment and DataFormItem.LabelHorizontalAlignment properties allow you to horizontally align the labels displayed above the data editor.
Data grid
Virtual horizontal scrolling
The new AllowVirtualHorizontalScrolling property greatly improves the performance of Xamarin.Forms DataGridView (when a large number of columns are used). If this option is enabled, when the user scrolls the grid horizontally, the DataGridView only presents the columns displayed on the screen and updates its UI elements .
DevExpress unit editor
In previous versions, the DevExpress Xamarin.Forms data grid used a standard editor to display and edit cell values. In v20.2, Xamarin DataGrid uses the following DevExpress editors instead:
v20.2 also includes three new column types:
- ComboBoxColumn
- AutoCompleteColum
- TimeColumn
Automatically filter rows
The Xamarin.Forms DataGrid view comes with a new Auto-Filter Row option, which can be used to integrate the search function into your mobile application. When the user enters a keyword in the Auto-Filter Row column, the data grid only displays those records that match the specified keyword.
You can control the search operators used (LIKE, CONTAINS, EQUALS, etc.) based on the data type associated with the column.
To display the automatic filter row, enable the ShowAutoFilterRow option.
Save/restore layout
Now, you can save the DataGrid layout to the stream and restore it as needed. The new Save / Restore API contains the following methods:
- SaveLayoutToStream-Save the layout as a specified stream in XML format.
- RestoreLayoutFromStream-restore the layout from the specified stream.
