WPF Dynamically Generated DataGrid

Despite being considered an upgrade from the Windows Forms datagrid, the WPF DataGrid has always felt like it was missing some features. The default style requires you to customize its appearance from the get-go. Additionally, developers ran into limitations with the standard WPF DataGrid and didn’t want to write colossal amounts of code to implement advanced features. In this article of the Mastering WPF DataGrid series, we saw some of the advanced DataGrid columns functionality. A DataGrid provides a collapsed and expanded views of a row where users can not only see the details of a row but it can also be used to edit and update the row data.

You can look at the WPF grid example in the image below, which shows a 10×5 grid table. Excel-like filtering can be enabled in unbound columns by setting AllowFilter property to true. Therefore, when you change this control’s current selection, it affects the CollectionView.CurrentItem property, which in turn affects the current record’s position of the grid too. How to add controls to the gridTo add controls to the grid layout panel just put the declaration between the opening and closing tags of the Grid. Keep in mind that the row- and columndefinitions must precced any definition of child controls.

Following are the sample outputs with IsSynchronizedWithCurrentItem set to true and false. This validation takes place while the focus moves from the current row to any other row. This type of validation is achieved by the CurrentCellValidating event.

1. Grouping can be performed interactively or declaratively on the Unbound Columns by using XAML code.
2. Such additional columns are called unbound columns as they do not belong to the data source.
3. A DataGrid provides a collapsed and expanded views of a row where users can not only see the details of a row but it can also be used to edit and update the row data.
4. There are many different ways to implement filtering in a .NET datagrid.
5. The ComponentOne WPF FlexPivot control uses pivot grids and charts to deliver in-depth business intelligence (BI) functionality.

Actually I could go on for a while about performance bottlenecks in WPF both from the data and the xaml perspective but that is debate which we can have on another day. It has become my custom to start each post with an image then I explain how I got there. So here’s the image, it shows a screen which can filter, sort and page in-memory data.

Wpf Dynamically Setting Number Of Rows

In addition to displaying and editing data, datagrids can be great tools for basic data analysis. Analysis features are where you’ll find the greatest divide between the standard WPF DataGrid and third-party controls. Frozen ColumnsThe data grid also supports the feature to freeze columns.

The Definitive Guide to WPF Datagrids

So, the binding’s source is the DataGridCell (defined via the relative source and the ‘dot’ path), the target is the column. The Path defines the source of the binding, which is in this case a ‘dot’. I https://traderoom.info/displaying-data-in-tables-with-wpf-s-datagrid/ don’t know what kind of a datagrid you are using, but binding should should be identical for all of them.

While these may not be “built-in” the same way as WinForms, they are fairly easy to implement, given the nature of the platform. We’ve denoted the “fairly-easy-to-implement” features with a green check in the table above. 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.

1. In the code below, a System.Windows.Data.RelativeSource object is used to describe the location of the binding source (the window) relative to the position of the binding target (the CheckBox).
2. Open-source and third-party component vendors like ComponentOne, Infragistics, and Telerik have filled in the gaps left open by the core .NET framework.
3. How to add controls to the gridTo add controls to the grid layout panel just put the declaration between the opening and closing tags of the Grid.
4. These unbound fields can be used, when you want to add some additional or custom information for each record.

I quickly got this solution working as I was able to implement it using a combination of the existing dynamic data filter and transform operators. The code was simple but alas had poor performance as each node had to create a filter from the original cache. Expand the Behavior within the tab and create a new databinding to the TextBox in the FilterEntry row. You’ll have to navigate into the Grid layout control to find and select the TextBox. For example, many WPF DataGrid features require custom converters and styles or rely on configuring the CollectionViewSource.

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. You can use the sample code below or replace this section with your own code. Next, we’ll look at the full feature set for a typical C# or VB.NET datagrid and how the features compare between different grid controls.

It is used by data-oriented applications for connecting to the data sources and manipulating data. It owns a set of data providers that retrieves data from the underlying sources and place it in an ADO.NET DataSet object. The DataSet object, which holds a collection of ADO.NET DataTable objects (represents the tables of data source), is created to populate a data-aware control like the grid with database data.

After setting , the final source code of  the MainWindow.XAML is given below.
