I'm struggling with binding to the checkbox of a tree view item ... I have the following class:
public class Filter : INotifyPropertyChanged
{
public string Key { get; set;}
public string Name { get; set; }
public FilterCollection Filters { get; set; }
private bool _count = false;
public bool Count
{
get
{
return _count;
}
set
{
if (_count != value)
{
_count = value;
this.NotifyPropertyChanged("Count");
}
}
}
private bool _isChecked = false;
public bool IsChecked
{
get
{
return _isChecked;
}
set
{
if (_isChecked != value)
{
_isChecked = value;
this.NotifyPropertyChanged("IsChecked");
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
public void NotifyPropertyChanged(string propertyName)
{
if (this.PropertyChanged != null)
{
this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
public Filter()
{
this.Filters = new FilterCollection();
}
}
I have a collection of these objects called FilterCollection of type ObservableCollection<Filter> ... what is the best and easiest way to bind the property IsChecked to the CheckState of the treeview item?
I'm binding the datasource in the code-behind, if that matters.
Silverlight newbie, my apologies.

Hello Matt,
Please take a look at the KB article demonstrating the usage of HierarchicalDataTemplate and ContainerBindingCollection in RadTreeView here.
You can also take a look at the example project that I've attached where HierarchicalDataTemplate and ContainerBindingCollection are used in order to data bind the State of the CheckBox of the TreeViewItems to the isSelected property of the business object.
Please let us know if you need more info.
Sincerely yours,
