I have a DataGrid in WPF which should show a collection of Books. Books look like this:
public class Book
{
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
private string title = "";
public string Title
{
get
{
return title;
}
set
{
title = value;
OnPropertyChanged("Title");
}
}
private List<Writer> writers = new List<Writer>();
public List<Writer> Writers
{
get
{
return writers;
}
set
{
writers = value;
OnPropertyChanged("Writers");
}
}
public Book() { }
public Book(string bookTitle)
{
this.Title = bookTitle;
}
}
Here is the Writer class:
public class Writer
{
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
private string fullname = "";
public string Fullname
{
get
{
return fullname;
}
set
{
fullname = value;
OnPropertyChanged("Fullname");
}
}
private string forename = "";
public string Forename
{
get
{
return forename;
}
set
{
forename = value;
OnPropertyChanged("Forename");
}
}
private string surename = "";
public string Surename
{
get
{
return surename;
}
set
{
surename = value;
OnPropertyChanged("Surename");
}
}
public Writer() { }
public Writer(string writersForename, string writersSurename)
{
this.Forename = writersForename;
this.Surename = writersSurename;
this.Fullname = string.Format("{0} {1}", this.Forename, this.Surename);
}
}
Now I want to show the writers in a single cell of the DataGrid. Something like this:
Title | Writer
------------------------
Book1 | Writer1
| Writer2
------------------------
Book2 Writer1
...
But in case I'm trying to bind the List to the cell it only shows "Collection" in the cell as value.
This is the XAML I'm using:
<ToolKit:DataGrid x:Name="dataGrid1" DataContext="{StaticResource ItemCollectionViewSource}" IsReadOnly="True" ItemsSource="{Binding}" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" AutoGenerateColumns="False" >
<ToolKit:DataGrid.Columns>
<ToolKit:DataGridTextColumn Header="Title" Binding="{Binding Path=Title}" />
<ToolKit:DataGridTextColumn Header="Writer" Binding="{Binding Path=Writers}" />
</ToolKit:DataGrid.Columns>
</ToolKit:DataGrid>
I've already tried to bind the cell to "Writers.Fullname" but that also doesn't work. Could you please help me, I couldn't find any examples of such a binding.

You could create DataGridTemplateColumn
column with ItemsControl
which would bind to Writers
list:
<ToolKit:DataGridTemplateColumn Header="Writer">
<ToolKit:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<ItemsControl ItemsSource="{Binding Writers}" DisplayMemberPath="Fullname"/>
</DataTemplate>
</ToolKit:DataGridTemplateColumn.CellTemplate>
</ToolKit:DataGridTemplateColumn>
