wpf ItemsControl binding problem

Question

I bind to a ItemsControl in my codebehind:

ColumnVisibilityItems.DataContext = gc.ColumnVisibility;

where ColumnVisibility is a ObservableCollection, also tried it with dictionary..

my markup

                <ItemsControl x:Name="ColumnVisibilityItems">
                    <Label Content="{Binding Path=Name}" />
                </ItemsControl>

while stepping through, i see the collection bound having 11 items. but ItemsControl renders only the first item in collection.

Is ItemsSource property necessary to be set for this to work? because whenever i try to set that in code behind, i get the exception saying items cannot be modified because they exist already.

Answer 1

basically you need to specify your Template. See the msdn docs for a fuller example

<ItemsControl x:Name="ColumnVisibilityItems" ItemsSource="{Binding}>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Label Content="{Binding Path=Name}" />
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>
