Question

Can anyone tell me if it is possible to create and add data to an unbound WPF Toolkit datagrid.

If it is in fact possible to do, can someone please provide an example of the following:

Programmatically: create a datagrid create a datagridtextcolumn add the datagridtextcolumn to the datagrid create a datagridrow set the text of the datagridtextcolumn for the row to ‘test’ add the datagridrow to the datagrid

I would like to create a datagrid that is unbound. My reason is that i would like to create a template column with multiple controls of different types and numbers – 2 checkboxes, 4 radiobuttons, 5 checkboxes, etc. – which are dynamically added at runtime and since the type and number are unknown cannot think of a way to databind them. I am happy to work unbound.

Thank you in advance!

Answer 1

You can use UserControl that will create desired controls.

Window1.xaml (snippet)

<dg:DataGrid ItemsSource='{Binding}' CanUserAddRows='False' AutoGenerateColumns='False'>     <dg:DataGrid.Columns>         <dg:DataGridTemplateColumn Header='Test' MinWidth='100'>             <dg:DataGridTemplateColumn.CellTemplate>                 <DataTemplate>                     <my:ControlA Foo='{Binding}'></my:ControlA>                 </DataTemplate>             </dg:DataGridTemplateColumn.CellTemplate>         </dg:DataGridTemplateColumn>      </dg:DataGrid.Columns> </dg:DataGrid> 

Window1.xaml.cs

public partial class Window1 : Window {     List<Foo> _items = new List<Foo>();      public Window1()     {         InitializeComponent();          _items.Add(new Foo { CheckBoxCount = 2, TextBoxCount = 1 });         _items.Add(new Foo { CheckBoxCount = 3, TextBoxCount = 0 });          DataContext = _items;     } } 

ControlA.xaml

<UserControl x:Class='Demo.ControlA'     xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'     xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>     <StackPanel x:Name='_placeHolder'>     </StackPanel> </UserControl> 

ControlA.xaml.cs

public partial class ControlA : UserControl {     public ControlA()     {         InitializeComponent();          Loaded += new RoutedEventHandler(ControlA_Loaded);     }      void ControlA_Loaded(object sender, RoutedEventArgs e)     {         if (Foo != null)         {             for (int it = 0; it < Foo.CheckBoxCount; it++)                 _placeHolder.Children.Add(new CheckBox());              for (int it = 0; it < Foo.TextBoxCount; it++)                 _placeHolder.Children.Add(new TextBox());         }     }      public static readonly DependencyProperty FooProperty =         DependencyProperty.Register('Foo', typeof(Foo), typeof(ControlA));      public Foo Foo     {         get { return (Foo)GetValue(FooProperty); }         set { SetValue(FooProperty, value); }     } } 

Foo.cs

public class Foo {     public int TextBoxCount { get; set; }     public int CheckBoxCount { get; set; } } 

Hope this helps.

P.S. It should be possible to refactor DataGridTemplateColumn into separate UserControl.
