[Silverlight] Checkbox List within ListBox using DataTemplate
DataTemplates in Silverlight are typically used for visual representation of your data.Data Templates are allow you to define a custom way in which the data should be display in a Control. They are particularly useful when you are binding an ItemsControl such as a ListBox to a collection. In this article, I have demonstrated how to declare DataTemplates in XAML and to read and apply them at runtime. Also one more thing over here is bind check box list in DataTemplate.
Here I Declare ListOfRecords class for Entity and bind it to Listbox Item Source.Looks like:
public class ListOfRecords : INotifyPropertyChanged
{
private bool _IsSelected = false;
public int ID { get; set; }
public string Content { get; set; }
public bool IsSelected
{
get { return _IsSelected; }
set
{
_IsSelected = value;
NotifyPropertyChanged("IsSelected");
}
}
public Brush BrushObj { get; set; }
public event PropertyChangedEventHandler PropertyChanged;
public void NotifyPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
}
After Creating Class My MainPage.xmal looks like
IN the XAML defines DataTemplates to display ListBoxItem for the ListBox. This DataTemplate also has a Checkbox element which is used to changed value for the Collection. The MainPage.Xaml.cs looks like:
private ObservableCollection
public ObservableCollection
{
get { return _objList; }
set
{
_objList = value;
}
}
public MainPage()
{
InitializeComponent();
_objList = new ObservableCollection
ListOfRecords supNode = new ListOfRecords() { ID = 0, Content = "Select All", IsSelected = false, BrushObj = new SolidColorBrush(Colors.Blue) };
_objList.Add(supNode);
for (int i = 1; i <= 10; i++)
{
ListOfRecords l = new ListOfRecords() { ID = i, Content = "Content : " + i.ToString(), IsSelected = false, BrushObj = new SolidColorBrush(Colors.Black) };
_objList.Add(l);
}
objList = _objList;
lstTemp.ItemsSource = objList;
Grid grd = new Grid();
for (int i = 0; i < 15; i++)
{
RowDefinition rd = new RowDefinition();
rd.SetValue(NameProperty, i.ToString());
rd.Height = new GridLength(25);
grd.RowDefinitions.Add(rd);
}
scrCriteriaSummaryTemp.Content = grd;
}
