Good performance is vital for a good application user experience, which makes it a key priority for all applications. As you know, users hate slow and laggy applications and that’s why performance is one of the highest concerns for developers and managers alike. Let’s use this model and bind the ItemsSource property of the RadGridView. It is of type IEnumerable, as you would expect, and indeed it can accept any enumerable.

1. There are “Ending” events, but no “Ended” events; therefore, the data visible to event handlers is not in its committed state.
2. You can perform insert, update and delete operations with validation and everything.
3. Make sure to be sure your collection is not read-only and that the type of objects in your data set have a public default constructor.
4. In the end, the end users of your application honestly don’t care what architecture you have used, as long as the app can get the job done.
5. This is indicted when the DataGrid invokes EndEdit on our bound item.

DataGrid with row details

So, if your data has a ParentID relationship for example, your data is good to go. If not all of your data is forming a hierarchy you can hide or show the row expander icons by binding it directly to your data. When your data is grouped you can change the sort direction of each group individually, and in addition, you can sort the data in each group by another column. This is indicated by the arrows shown in the group buttons appearing in the group panel and in the column headers, as can be seen in the screenshots I have added above. Sorting by more than one column is supported as well, so you can get that much more insight into your data.

Excel-like Drag-to-Select Rows and Cells

It simply renders rows one below the other instead of nesting them on many levels. Extended WPF Toolkit™ by Xceed is the number one collection of WPF controls, components and utilities for creating next generation Windows applications. Use it to build professional looking, modern, and easy to use WPF applications. It has been downloaded more than 1 million times here, on Codeplex, and on NuGet.

Binding in a Layered Application

In this example, synchronized views of the Customer (master) and Orders (detail) tables of the Northwind database will be displayed. This design-time support is certainly nice to have; however, it is very easily missed as it inserts a single menu option into an existing context menu. The WPF designer (Cider) does not follow the conventions of the Windows Forms and ASP.NET designers which indicate that a control has design-time support by the presence of a small button in the top right corner. And, the modified XAML below uses the ObjectDataPerovider class to define an instance of the above class as our data source. Note that we are still binding the DataGrid’s ItemsSource to the inherited DataContext.

Column sorting, reordering and resizing

This feature allows you to show your data with minimal to no configuration. It is great for simple scenarios, or for situations in which the shape of data that will be presented is determined at runtime. Controlling the generated columns can be done using either the familiar Display attribute or the DataGrid AutoGeneratingColumn event. The latter gives you complete control over the generated columns and the generation process itself. The ObservableCollection class is a good candidate for our data binding needs. It exposes a CollectionChanged event which is fired whenever items are added or removed from the collection.

Then, I use various attached properties and behaviors to wire the filtering behavior, classes that define the look and feel of the text box and whether the TextBox is visible or enabled. Most of the rest of the code is defined within MainWindow.axaml file, only references to style files are defined within App.axaml. The datagrid control is contained in a separate assembly, Xceed.Wpf.DataGrid, which must be added to your project and then referenced where necessary.

In either case, there is no good or bad way, but an automatic and a manual one. When you have a lot of information and you can’t display it all using just columns, maybe you can show that information in a row detail. Each WPF DataGrid row is capable of presenting additional information if the form of a row detail. The advantage of this approach is that it can be configured to be displayed only when the row gets selected. This can reduce the number of columns and give your data grid a neater and more compact layout, while still providing all the information the user needs. You can also show the row details at all times, regardless of whether the row is selected or not, if you prefer.

When combined with lazy loading it can lead to performance improvements as well, because you will be fetching only the data you are actually showing on the screen. To enable grouping you have to define a CollectionView that contains to least one GroupDescription that defines the criterias how to group. This element is used to render the sort arrows, and optionally render a thin separator between each header if SeparatorVisibility is set to Visible.

A detailed overview of binding groups can be found on Vincent Sibal’s blog, and their usefulness extends far beyond that of validating DataGrid rows. By default, detail descriptions are automatically created for most detail relation types; however, they can also be explicitly defined. If some of the missing features are a must, you can combine the two components together. You can display the entire dataset using virtual grids and when https://traderoom.info/ the user wants to view a particular portion of the data in more detail, you can display this data in a DataGrid. Utilizing the QueryableCollectionView we talked about above is very neat in scenarios like this, because it gets populated with the proper FilterDescriptors whenever your users apply filters to your virtual grid. You can use this as an opportunity to populate your DataGrids and perhaps some graphs to create a dashboard.

Yavor is a Senior Software Developer on the Telerik UI for Xamarin team. wpf advanced datagrid His 10+ years of XAML and WPF experience were gained in the Telerik UI for WPF and Silverlight suite as well as many LoB applications.

What we really need to do is determine when the user finishes editing an item in the grid. The datagrid included in the Plus Edition provides a stunning, shaded appearance and capabilities such as inertial smooth scrolling and animated full-column reordering—which mimics the physics of real-life movement. Add to that the datagrid’s zero-lag data virtualization, and you have the fastest WPF datagrid around—in performance and feel. It also easily handles millions of rows and thousands of columns, and integrates quickly into any WPF app.

As you can see from the resulting screenshot, or if you run the sample yourself, the details are now shown below the selected row. As soon as you select another row, the details for that row will be shown and the details for the previously selected row will be hidden.

Connect and share knowledge within a single location that is structured and easy to search. Second thing you need to do is defining a template how the groups should look like. You can do this by setting the GroupStyle to something like the following snippet.

By default, column widths, visibility, positions, and fixed-column counts as well as grouping and sorting criteria are persisted; merged columns, their positions, and their visibility can also be persisted. However, these settings can be modified when calling the SaveUserSettings and LoadUserSettings methods. The last and empty row will let you add to the data source, simply by filling out the cells. I am trying to find a way to create the datagrid dynamically (in-code) so that I can create multiple copies of it and bind it to different datasources at run-time.

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. You can then invoke methods on this class in order to provide data to your controls. This method yields a few extra benefits which are described in Beatriz Stollnitz’s blog.
