Fit automatictly the width of listbox's child

I have a GroupBox in a Listbox and the GroupBox's width automaticly fit it's content. I want to fit the ListBox's width (even if resized) and never have any Scrollbar.

Here is my XAML :

<ListBox Name="ListBox_1">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <GroupBox Header="{Binding Name}" Margin="5">
                <!--DATA-->
            </GroupBox>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

I have tried to set set the HorizontalAlignment's property of the GroupBox, but there is no effect. Thanks in advance.

Solution

  • you can use Grid or stackPanel within GroupBox for display data.and set Grid Height and Width dynamically auto or *.and set ListBox ItemTemplate Propery HorizontalContentAlignment="Stretch"
