dotnet DataGridExtensions: Modular extensions for the WPF DataGrid control
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. The WPF DataGrid can be styled in a highly flexible manner https://traderoom.info/displaying-data-in-tables-with-wpf-s-datagrid/ by applying Styles or Templates in the same way as for all of the other WPF controls.
We’ll focus on using ObservableCollections to keep your WPF SQL Server DataGrid dynamically updated, reflecting database changes seamlessly. This ensures a responsive user interface and avoids common pitfalls. The workaround given here uses validation to ensure that all the DataTable constraints are satisfied before the updates are committed.
Built-in data error indication and validation
It would make sense to remove this column and the generated ID from the interface. With the above code, the design-time support of the DataGrid is now available, allowing you to configure which columns are present, their bindings, sorting, etc. 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. My application implements a simple Calculation Chain, as spreadsheets do. It has a TextBox into which the user types some numerical values and as soon as it is edited, the code proceeds to update all the dependent fields. Stacked headers (multiple header rows) allow users to show unbound header rows.
Right to left (RTL)
Interestingly, the DatePicker picks up the current culture, whereas the TextBlock binding does not (yes, I live in the UK!). However, it should be noted that the validation support for the WPF DataGrid is currently a bit patchy. The row level validation which was advertised as part of the first DataGrid CTP didn’t quite make the release, and the recently released DataGrid v1 still has a number of validation related issues.
- The HeaderVisibility property is used to show and hide row and column headers.
- You use code in the above event handlers when a new record is being added or updated in the UI.
- Merged column headers can be used to present data more clearly and logically.
- Users can search forwards or backwards, and use keyboard shortcuts.
- Now, our goal is to bind the xamDataGrid control to a data source so we can load data in the grid control.
- This article will present a few common validation scenarios, demonstrating how the DataGrid can be configured to perform these tasks.
In addition to automatic filtering, the grid provides a FilterRow that allows users to specify a filter expression used by the DataGridCollectionView to filter data items. Filter expressions entered in FilterCell follow a specific syntax and rules. This may be cumbersome to learn for users, and this is where Advanced filtering comes to the rescue. Advanced filtering provides a UI interface to help users build filter expressions without the need to learn yet another syntax. In this article, I demonstrated how to use a DataGrid control in WPF, set its properties and display data using an object collection.
The second problem was how to obtain the correct text to measure. Again the DataGridColumnStyle has a method available that might help. It�s called GetColumnValueAtRow, and it will need a CurrencyManager, whatever that is, for obtaining the values. This shifts the problem to obtaining a CurrencyManager, the documentation helps out again.
WPF DataGrid – A High Performance and Feature-rich Grid Control
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. The SelectionMode property decides if the DataGrid allows only a single row or multiple rows selection. The following code snippet sets the SelectionMode to Extended. The Width and Height properties represent the width and the height of a DataGrid. The Name property represents the name of the control, which is a unique identifier of a control.
Also notice the ugly piece of background shown besides the last column. The row height sizing method has been fixed to work with both ReadOnly DataGrids and DataGrids that can be written to. Also a new more advanced explanation how it all works is available.
These UI objects simply wrap their data object counterparts in order to expose the same properties. 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.
As you saw in Figure 2, all public properties of the Author object are represented as columns of the DataGrid. This is because by default, the AutoGenerateColumns property of DataGrid is true. If you do not wish to generate automatic columns, you simply need to set this property to false. The .NET DataGrid control for WPF is still supported and used today with .NET 8.0 (and soon .NET 9.0) Windows desktop applications.
Insertion Row
Choose from 27 built-in themes using the SfSkinManager for a rich user interface. Easily customize all aspects of the DataGrid appearance using the Theme Studio utility. Create records on demand by automatically enabling data virtualization. Load millions of records of data instantly with virtualization enabled.
The app may also include some advanced UI operations such as sorting, searching, filtering, multiple views, and data export. There are loads of things that this control has built in; data binding, some events and a professional view are available. Next to that, there are also a lot of customized implementations available for adding comboboxes to the grid, or making the columns automatically size their widths. But despite all of this, there is (at least) one thing that is still not found at all. Implementing data validation rules at both the database and application levels ensures that only valid data is stored and processed.
