How to bind ListCheckBox to WPF? The situation is such that the width of the checkbox is equal to the length of the text in it (less than the ListBox, and accordingly, in order for the Checked to work, you need to hover over the text and click (made crutches increased the width of the checkbox to the width of the listbox). But I would like to bind them instead of using a crutch.

<ListBox x:Name="listbox_products" Width="200" Height="300" Background="DarkGray" Margin="5,5,5,5" ItemsSource="{Binding GetAvailProductsOnProject}" > <ListBox.ItemTemplate> <DataTemplate> <CheckBox x:Name="CheckBox_CheckProduks" Width="300" IsChecked="{Binding IsSelected}" Content="{Binding Продукт}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox>

There are several problems here. First, you need to stretch the cell to the full width. Secondly, you need to ensure that the content of your checkbox does not go beyond the right border.

To do this, do this:

 <ListBox x:Name="listbox_products" Width="200" Height="300" Background="DarkGray" Margin="5,5,5,5" ItemsSource="{Binding GetAvailProductsOnProject}" HorizontalContentAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Disabled"> <ListBox.ItemTemplate> <DataTemplate> <CheckBox IsChecked="{Binding IsSelected}"> <TextBlock Text="{Binding Продукт}" TextWrapping="Wrap" /> </CheckBox> </DataTemplate> </ListBox.ItemTemplate> </ListBox>

All items placed in the ListBox are wrapped in a ListBoxItem, so you need to stretch ListBoxItem. You can do it like this:

 <ListBox ...> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="HorizontalContentAlignment" Value="Stretch"/> <Setter Property="VerticalContentAlignment" Value="Stretch"/> </Style> </ListBox.ItemContainerStyle>

The width of the CheckBox should not be explicitly set; remove the Width setting from the markup. The CheckBox will stretch the entire width of the container (ListBoxItem) and, accordingly, the entire width of the ListBox.
