The FrozenColumnCount property represents the number of columns that user can not scroll horizontally. The following code snippets sets AreRowDetailsFrozen to true and FrozenColumnCount to 2. The ColumnWidth and RowHeight properties of DataGrid are used to set the default column width and row height of DataGrid columns and rows. The last and empty row will let you add to the data source, simply by filling out the cells. When choosing a data grid for WPF applications, developers need a solution that is performant, customizable, and easy to integrate.
Automatic Excel-like filtering lets end-users better manage the data they see, as do the fixed-column and the custom sorting functionalities. UI automation enables script-based testing and assistive technology. Finally, UI, column, and data virtualization reduces load time and memory https://traderoom.info/displaying-data-in-tables-with-wpf-s-datagrid/ usage. Windows Forms was the preferred option for developing a desktop Windows application until .NET 3.0, when Microsoft added WPF to the .NET stack of frameworks.
The event handler code written in Listing will also save the record in the database. Once a record is added successfully, you will see a popup message confirming the action. By default, datagrids will automatically generate all the columns based on your data source. That sounds convenient, but in reality, databases store strange fields like “last modification date” and odd look-up IDs that you don’t always want or need to display to the user. So, in most cases, you will need to perform some slight modifications to the columns, such as reordering and formatting.
The Standard .NET WPF Datagrid Features
- Note that you must set the AutoGenerateColumns property to False unless you want the combined effect of autogenerated columns and manually defined columns.
- You can see in the bottom of the window, there is an option to add a FieldLayout, move up and down to change a field position, and the Add button to add.
- 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.
- When declaring the DataGrid in code behind, a default view must be set.
- It requires that you first complete the tutorial above to set up the application and data source.
With .NET 3.0, Microsoft included a new DataGrid control for its new presentation layer, WPF. One might speculate that WPF (Windows Presentation Foundation) was intended to replace Windows Forms; however, both are built upon the same Win32 libraries and are still widely used today. The WPF DataGrid offered a slightly different feature set and limits than the Windows Forms version. 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. Interestingly, the DatePicker picks up the current culture, whereas the TextBlock binding does not (yes, I live in the UK!). The WPF DataGrid can be styled in a highly flexible manner by applying Styles or Templates in the same way as for all of the other WPF controls.
Complete Datagrid Customization (Advanced)
In this article, we discuss the evolution of the .NET datagrid, the top features of a WPF datagrid, and how to use a datagrid in your WPF application code. To refilter the data items displayed in a view, the Refresh method can be called on the ItemsSource. To delete a record, simply select a row in the data grid and press the DELETE button on the keyboard. One of the best parts of using the xamDataGrid is, it supports default CRUD (Create, Read, Update, and Delete) data operations. You only have to write a few lines of code to add a new record or update and delete existing records in a database via the grid. To do that, click on the property in XAML and press F4 to open the Properties window.
A WPF datagrid is a user interface control for displaying, editing, and analyzing large data sets within a Windows desktop application. You can think of a datagrid like a spreadsheet table with features like column sorting, column resizing, and built-in cell editing bound to your data source. WPF (Windows Presentation Foundation) is a .NET framework for developing modern desktop applications with C# or VB.NET code. Every datagrid control automatically generates columns for each field and comes with basic editing and sorting features out of the box. In simple cases, this is all you need, but notice that every column will display in the exact order as they are discovered in the data source. Most datagrid controls automatically generate columns for each field and come with basic editing and sorting features out of the box.
There is a DataGrid provided for UWP (WinUI 2), but it’s not currently available for WinUI 3 or .NET MAUI. 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. This example demonstrates how to use a DataGrid to perform CRUD operations via binding where the database integration is decoupled via a Data Access Layer (DAL). The complete example above is found in the MasterDetailExample class. However, please note that any exception that occurs when the data is being updated is not being handled, which will result in the in-memory DataTable no longer being synchronized with the database.
List controls
The WPF DataGrid has an interesting feature called RowDetails, which is an area of customisable content beneath each row. You can use the RowDetailsVisibilityMode property of the DataGrid to specify whether to display details just for the selected rows or for all the rows. 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. The workaround given here uses validation to ensure that all the DataTable constraints are satisfied before the updates are committed.
Use saved searches to filter your results more quickly
- Here you can drag and drop the column header to group data by the xamDataGrid field name (or column name).
- The xamDataGrid has a property, AllowEdit on FieldSettings, that makes xamDataGrid rows editable.
- 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 MaxColumnWidth and MinColumnWidth properties represent the maximum width and minimum width of columns in a DataGrid.
- 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 costs of developing the features yourself are typically higher than buying off-the-shelf. Third-party libraries pay for themselves with the saved time and resources. Some of these features are possible with the standard datagrid, but others require writing a lot more code. If you use a third-party datagrid, you can enable most of these features rather quickly with just a few lines of code.
As you can see from Figure 1, Infragistics WPF controls starts with XamControlName and the XamDataGrid is the DataGrid control. XamDataGrid provides built-in data-binding and data operations such as filtering, search, sorting, and others. WPF provides several built-in data controls including the DataGrid control.
