How to add a StackPanel in a Button using c# code behind (i.e. convert the following XAML to C# )? There is no Button.Children.Add...
<Button>
<StackPanel Orientation="Horizontal" Margin="10">
<Image Source="foo.png"/>
</StackPanel>
</Button>
Image img = new Image();
img.Source = new BitmapImage(new Uri("foo.png"));
StackPanel stackPnl = new StackPanel();
stackPnl.Orientation = Orientation.Horizontal;
stackPnl.Margin = new Thickness(10);
stackPnl.Children.Add(img);
Button btn = new Button();
btn.Content = stackPnl;
Set Button.Content instead of using Button.Children.Add
As a longer explanation:
Content.Children - e.g. StackPanel, Grid, WrapPanel, Canvas, etc. As your code already shows, you can set the Content of a Button to be a Panel - this would ehn allow you to then add multiple child controls. However, really in your example, then there is no need to have the StackPanel as well as the Image. It seems like your StackPanel is only adding Padding - and you could add the Padding to the Image rather than to the StackPanel if you wanted to.
Use like this
<Window.Resources>
<ImageSource x:Key="LeftMenuBackgroundImage">index.jpg</ImageSource>
<ImageBrush x:Key="LeftMenuBackgroundImageBrush"
ImageSource="{DynamicResource LeftMenuBackgroundImage}"/>
</Window.Resources>
and in Codebehind
Button btn = new Button();
btn.HorizontalContentAlignment = HorizontalAlignment.Stretch;
btn.VerticalContentAlignment = VerticalAlignment.Stretch;
StackPanel stk = new StackPanel();
stk.Orientation = Orientation.Horizontal;
stk.Margin = new Thickness(10, 10, 10, 10);
stk.SetResourceReference(StackPanel.BackgroundProperty, "LeftMenuBackgroundImageBrush");
btn.Content = stk;
In Xaml :
<Button x:Name="Btn" Click="Btn_Click" Orientation="Horizontal" Margin="10">
<StackPanel>
<Image Source="foo.png" Height="16" Width="16"/>
</StackPanel>
</Button>
In C# :
Button btn = new Button();
StackPanel panel = new StackPanel();
Image img = new Image
{
Source = "../foo.png"
}
panel.Children.Add(img);
btn.Content = panel;
I advise you to put the image in xaml resources :
<Window.Resources>
<BitmapImage x:Key="Img" UriSource="/Img/foo.png"/>
</Window.Resources>
And call it like this :
Image img = new Image
{
Source = (BitmapImage)FindResource("Img")
};
