FlexGrid: A WPF Data Grid

This section is a tutorial on getting started on building a WPF application and working with the standard https://traderoom.info/displaying-data-in-tables-with-wpf-s-datagrid/ DataGrid control. The ComponentOne products are provided by MESCIUS, but you can also download their WPF datagrid on nuget.org. One of the main strengths of FlexGrid is the ability to customize every aspect of the appearance of the entire grid and individual cells. Easily embed sparklines, images, ratings, or any UI element in the cells. Now, let’s add a Button with a click event handler that will be responsible for exporting to Excel. The following code in Listing is the code behind event handlers where we can write code that will be executed when these events are fired.

The “search as you type” feature is also less refined, which can be limiting in applications where users need to quickly sift through large datasets. The .NET DataGrid control for WPF is still supported and used today with .NET 8.0 (and soon .NET 9.0) Windows desktop applications. The standard DataGrid control is a great starting point for basic functionality. Open-source and third-party component vendors like ComponentOne, Infragistics, and Telerik have filled in the gaps left open by the core .NET framework.

1. The chosen mode indicates how the advanced filtering control is triggered.
2. The event handler code written in Listing will also save the record in the database.
3. The HeaderVisibility property is used to show and hide row and column headers.
4. Advanced filtering provides a UI interface to help users build filter expressions without the need to learn yet another syntax.
5. To do that, click on the property in XAML and press F4 to open the Properties window.
6. One of the first operations we do on a data-bound control is, to bind the control to a data source and load data into the control.

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. In this example, synchronized views of the Customer (master) and Orders (detail) tables of the Northwind database will be displayed. Fortunately, the absence of this control has not hampered the popularity of WPF.

DataGrid allows you to reorder columns by dragging a column but you may disable this feature by setting the CanUserReorderColumns property to false. The following code snippet sets CanUserReorderColumns properties to false. 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. The WPF datagrids will automatically generate all the columns based on your data source.

Folders and files

The last time we looked at the DataGrid for WPF we had looked at Grouping and Sorting. Today let’s look at the Filtering options that the datagrid offers. Now, on the Button click event handler, we use the DataPresenterExcelExporter object and its ExportAsync method that is responsible for creating a new Excel document with the xamDataGrid records in it.

1. This is possible thanks to its stunning, shaded appearance and capabilities such as inertial smooth scrolling and animated full-column reordering—which mimic the physics of real-life movement.
2. 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.
3. Now, you’ll observe that when you type in the TextBox, the FlexGrid automatically filters.
4. Also, a tooltip is defined that displays the validation error message.

WPF Datagrids

The complete example above can be found in the DataSetCRUDExample class which shows how a CRUD interface can be created for a DataSet with a few lines of code. 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 GridLinesVisibility property is used to make grid lines visible. Using this option you can show and hide vertical, horizontal, all, or none lines.

In this article, you will learn how to use a WPF DataGrid control, set its properties, and load data from a collection. Raw performance is supplemented by advanced data loading and caching techniques including asynchronous stealth paging, zero lag data virtualization, and preemptive data loading. Perceived performance is greatly enhanced thanks to a fully animated and fluid experience. It was released in 2007 and has been consistently updated since then. It is used in many major business applications, and is also used by portions of Visual Studio. The source could just as easily have been a database table/view or even an XML file – the DataGrid is not picky about where it gets its data from.

Note that you must set the AutoGenerateColumns property to False unless you want the combined effect of autogenerated columns and manually defined columns. However, there is also a good use for that scenario, such as adding custom columns to your data source. One of the benefits of WPF is that it’s the most easily extensible .NET platform due to its XAML-based architecture. With XAML, we can customize templates of components to add extra features. While that’s still more development work than setting a built-in feature, it’s still a lot easier than extending a control in Windows Forms or for the web.

Currently, there is a lack of documentation and examples demonstrating common DataGrid usage scenarios (which is to be expected, as it is an out-of-band release). This article provides a number of simple usage examples which will hopefully be of use to anyone considering using the WPF DataGrid. The HorizontalScrollBarVisibility and VerticalScrollBarVisibility properties of type ScrollBarVisibility enumeration control the horizontal and vertical scrollbars of the DataGrid. The default value of these properties is Auto, that means, when scrolling is needed, you will see it, otherwise it will be hidden.

Xceed DataGrid for WPF is not only the most mature and therefore rock-solid grid control for Windows Presentation Foundation. It is also the first to provide a rich, fluid, and high performance user experience. This is possible thanks to its stunning, shaded appearance and capabilities such as inertial smooth scrolling and animated full-column reordering—which mimic the physics of real-life movement.

Step 2: Implement Search Box Filtering with No Code

For example, in some cases, you might wish to submit a batch of changes via a “Submit” button, or you may wish to have the database updated as the user commits each row edit. In order to support these, the rows that the DataTable contains have a RowState property which indicates whether they contain changes which should be synchronized with the database. The synchronization process is easily achieved via the TableAdapter’s Update method.

One other subtlety of this example is that the primary key is read only, because the generated DataSet’s update methods assume that the primary key has not been modified. However, when the data grid selection changes to the empty row at the bottom, the column’s read-only state is toggled to allow the user to add a new Customer row. It’s easy to understand why it’s the most-adopted WPF datagrid available and used by Microsoft in Visual Studio. Fast, powerful, and mature, with a 13-year track record, this is the only WPF datagrid that provides a rich, fluid, and high-performance user experience. It is frequently updated and backed by a responsive support and development team whose sole ambition is your complete satisfaction.

Rich printing allows for easy report creation, and exporting lets Excel lovers access the data in that tool if needed. Flexible filtering and powerful sorting capabilities let users find and visualize data quickly, and persist/restore features let them keep their setups. FlexGrid also offers an extensive array of native advanced features that enhance both development efficiency and end-user experience. One such feature is the transposed grid option, which allows you to easily flip rows and columns for a unique and flexible data presentation.
