Getting Started with WPF DataGrid control Syncfusion

The CardView and CompactCardView classes provide card-view layouts for the data items in a grid. Either layout can be used to display data items as cards; however, the compact card-view layout applies well when a database has many columns but few of the fields contain data. In this case, the fields that do not contain data will not be displayed in the cards, giving them a more compact appearance. The WPF DataGrid has columns of type Text, Hyperlink, CheckBox, and ComboBox. If these column types do not fulfill your needs, either in read-only mode or when the cells are in edit mode, then you can define your own column type using templates. Users of the ASP.NET GridView will find this approach very familiar; you simply define a DataTemplate for rendering your data in read-only or edit mode.

Sorting, Grouping, and Filtering

Fixed columns are separated from their scrollable counterparts by a fixed-column splitter, which can be dragged to add or remove fixed columns. Likewise, column-manager cells can be dragged to the left or right of the fixed-column splitter to add or remove fixed columns. The appearance of the fixed-column splitter can be defined for each row type. The WPF DataGrid control is used for efficiently displaying and manipulating tabular data. Its rich feature set includes functionalities like data binding, editing, sorting, filtering, grouping, and exporting to Excel and PDF file formats. It has also been optimized for working with millions of records, as well as handling high-frequency, real-time updates.

Master / Detail View

Refer to the Xceed Data Grid documentation for more information on customizing themes. Open your WPF project in Visual Studio and navigate to the XAML file where you want to add the data grid. First, your data model FlaggedVisitor must implement INotifyPropertyChanged even when the properties are not changing. SfDataGrid control can be added to the application by dragging it from Toolbox and dropping it in Designer view. Create new WPF Project in Visual Studio to display SfDataGrid with data objects. The mission of MESCIUS is to provide customers with the premier studio of innovative UI controls, tools, and solutions including deep functionality reporting, analysis, and spreadsheet platforms.

Stacked headers

Furthermore, when a user adds a new item to the DataGrid, the object is initially added to the bound collection in a non-initialized state, so we would only ever see the object with its default property values. What we really need to do is determine when the user finishes editing an item in the grid. When the user edits the Customers data within the DataGrid, the bound in-memory DataTable is updated accordingly. It is up to the developer to decide when changes to the DataTable are written back to the database depending on the requirements of the application.

If you want your data object (OrderInfo class) to automatically reflect property changes, then the object must implement INotifyPropertyChanged interface. In the markup, I have added the AutoGenerateColumns property on the DataGrid, which I have set to false, to get control of the columns used. As you can see, I have left out the ID column, as I decided that I didn’t care for it for this example. For the Name property, I’ve used a simple text based column, so the most interesting part of this example comes with the Birthday column, where I’ve used a DataGridTemplateColumn with a DatePicker control inside of it. This allows the end-user to pick the date from a calendar, instead of having to manually enter it, as you can see on the screenshot.

Column Splitter Control

  1. Merged column headers can be used to present data more clearly and logically.
  2. Cells can also be merged programmatically to display their content in a combined way (as shown by the City and Country columns in the image below).
  3. You can customize the editing operations by handling SfDataGrid.CurrentCellBeginEdit and SfDataGrid.CurrentCellEndEdit events.
  4. I would like to set such size for the DataGrid (standard, from WPF) so all cells (text) would be fully visible.
  5. A second data source is added, again via the ObjectDataProvider, with the window displaying two DataGrids, each bound to their respective data sources.

The resulting window will contain a grid which displays all the columns of the Customers table, thanks to the AutoGenerateColumns property of the DataGrid which defaults to true. When columns are auto-generated, you can handle the SfDataGrid.AutoGeneratingColumn event to customize or cancel the columns before they are added to the SfDataGrid. Xceed offers the Plus Edition for developers that want to support the project, get additional controls and features, get updates and professional support, and work with a version a few releases ahead. To enable grouping you have to define a CollectionView that contains to least one GroupDescription that defines the criterias how to group.

Note also that because the validation error does not relate to an individual property of our business object, none of the DataGrid cells are highlighted. In order to make the failure more obvious, the style of the row has been modified to add a red border. This rule iterates over all of the items within the binding group (i.e., the DataGrid row) probing them for errors. In this case, the IDataErrorInfo.Error property is used for object level validation. An alternative method for providing data to your controls is through the use of an ObjectDataProvider. This class enables you to instantiate an object within your XAML resources for use as a data source.

The summaries are calculated in an optimized way and the updated summaries are displayed in real-time scenarios. Data processing operations like sorting, filtering, grouping, summarizing, and real-time updating are handled efficiently using PLINQ. A Stats Editor Control which gives the user the ability to view, add, edit and remove the statistics displayed in StatRows. Instead of the default context menu style (shown above), the built-in dialog control can be used for a different look/behavior (shown below). Note also that the read-only view of this cell uses the StringFormat property of the Binding class to specify a format which matches that which is used by the DatePicker.

Group data by one or more columns either through mouse and touch interactivity in the group drop area or in code behind. The IsAsync property can be used when the get accessor of your binding source property might take a long time. One example is an image property with a get accessor that downloads from the Web. To activate this feature, set the DataGrid’s AllowDrag property to true, and the DragBehavior property to “Select”. The View must be a valid instance or subclass of TableView (ex. TableFlowView, TreeGridflowView).

This works well enough; however, one of the advertised features of the WPF DataGrid is design-time support. If you right-click on the DataGrid in the Visual Studio designer, you will see a DataGrid entry in the context menu. However, the sub-menu is a little sparse, and displays the message “You need to set ItemsSource to enable some column operations”. The problem is that the DataGrid designer is unable to inspect the contents of the ItemsSource property of the DataGrid if it has been constructed in the code-behind. To populate your data grid with data, you need to bind it to a data source. The data source can be a collection of objects, a database, or a web service.

The ShowPrintPreviewWindow and ShowPrintPreviewPopup methods provide print preview capabilities. ShowPrintPreviewPopup should be used when the application is being deployed as an XBAP, as XBAP applications cannot open new windows. This article will present a few common validation scenarios, demonstrating how the DataGrid can be configured to perform these tasks. Note that the examples I give all delegate the validation logic to the bound object itself, rather than having the rules which dictate whether an object state is valid or not live entirely within the UI. Both are, of course, possible; however, it is my preference that the validation logic should not live in the presentation layer. I would like to set such size for the DataGrid (standard, from WPF) so all cells (text) would be fully visible.

I have window with DockPanel, with DataGrid in it, so when I resize the window, all nested widgets (DockPanel and DataGrid) are resized accordingly. After completing these steps, your Xceed Data Grid for WPF should be activated and ready for use. GroupBackgroundConverter.csThis simple implementation supports different alternation counts, e.g. to alternate between three colors.

By default, detail descriptions are automatically created for most detail relation types; however, they can also be explicitly defined. Handling delete operations is relatively straightforward, but how about updates or insertions? You might think that the same approach can be used, the NotifyCollectionChangedEventArgs.Action property does include Add operations; however, this event is not fired when the items within the collection are updated.

A popular alternative to the previous example, where exceptions are thrown on the property setters of the data objects, is the use of the IDataErrorInfo interface. Objects that implement this interface are validated on demand, rather than each time their state changes. For a discussion of how this can make your business objects more useable, the article Fort Knox Business Objects makes interesting reading. They also have the advantage that they are able to validate state which depends on multiple properties; there is clearly a synergy here with BindingGroups.

In the next chapters, we’ll look into all the cool stuff you can do with the DataGrid, so read on. In the Reference Manager window, click on “Browse” and navigate to the installation folder of the Xceed Data Grid for WPF library. My current workaround is to have a custom List which would append a flag based on the logic I mentioned above. The DataTrigger then reads the flag and colors each row based on the bool value. This section provides a quick overview for working with the WPF DataGrid (SfDataGrid) for WPF. As you can see from the resulting screenshot, or if you run the sample yourself, the details are now shown below the selected row.
