A article show how to use the new DataGrid in WPF

Introduction

After WPF was released without a DataGrid, Microsoft received loads of criticism! Thy have finally released the highly anticipated DataGrid (CTP)! Here is a short introduction on how to use the DataGrid

Required

Download the WPFToolkit here

To run my sample application, also install the Northwind database

Getting started

Create a blank WPF application and add a new item (LINQ-to-SQL Class). Drag the required tables from the Northwind database onto the design surface

Now that we have a simple database to work from, lets add the DataGrid to our project. Add a refrence to WPFToolkit.dll and add the namespace to your main window's XAML

xmlns:dg="clr-namespace:Microsoft.Windows.Controls;assembly=WpfToolkit"

The simples DataGrid we can create is by adding the DataGrid in our window and setting the AutoGenerateColumns to True! This will automatically generate a column for each field in the table. I also gave the DataGrid a name so I can access it in my code-behind

<dg:DataGrid 
    x:Name="NorthwindDataGrid"
    AutoGenerateColumns="True" />

All that is now left to do is get the table from the database (using my created LINQ-to-SQL class) and setting the DataGrid's ItemSource (The DataGrid inherits from ItemsControl)

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    using (NorthwindDataContext dc = new NorthwindDataContext())
    {
        NorthwindDataGrid.ItemsSource = dc.Customers.ToList();
    }
}

And here is the DataGrid in its full glory…

That was easy, what else can this baby do?

By default, the DataGrid supports resizing, reordering, sorting, adding and removing. This behavior can be controlled with the following properties:

  • CanUserAddRows
  • CanUserDeleteRows
  • CanUserResizeColumns
  • CanUserReorderColumns
  • CanUserSortColumns

On editing a cell, the following events gets fired...

  • PreparingCellForEdit
  • BeginningEdit
  • CommitingEdit
  • CancelingEdit

The DataGrid derives from MultiSelector allowing true multi row selection scenarios. The selection mode is controlled by setting SelectionMode to Single or Extended

The SelectionUnit can also be changed to only select a cell (DataGridSelectionUnit.Cell), row (DataGridSelectionUnit.FullRow) or cell/row (DataGridSelectionUnit.CellOrRowHeader)

The DataGrid also fully support clipboard copy/past
