Button border thickness from code behind

Question

I am very new to wpf, and right now I am working with buttons, and so I want to change buttons border thickness, but from code behind not in XAML, and what I did was next:

var converter = new System.Windows.Media.BrushConverter();
var brush = (Brush)converter.ConvertFromString("#83D744");
btn0.Background = System.Windows.Media.Brushes.Transparent; // This is applied to button
       btn0.BorderThickness = new Thickness(1); //Thickness wont apply to button I dont know why
        btn0.BorderBrush = brush; //This is also applied to button

Solution 1

The default border thickness for Buttons is 1 so nothing will change if you set it to 1.

To see a change just set it to something different:

button.BorderThickness = new Thickness(1, 1, 1, 3);

Solution 2

Since the default button template don't have Border property, More information you can visit: here. So if you want a border around button you have to add your own style, Like:

<Style x:Key="ButtonStyle" TargetType="{x:Type Button}">
   <Setter Property="Template">
      <Setter.Value>
         <ControlTemplate TargetType="{x:Type Button}">
            <Border x:Name="border" BorderBrush="Transparent" BorderThickness="0" Background="Transparent">
               <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
            </Border>
         </ControlTemplate>
      </Setter.Value>
   </Setter>
</Style>

In above code all properties like: BorderBrush, BorderThickness and Background are hard coded and you can't set these property from code behind. if you want to do so you have to write style like:

<Style x:Key="ButtonStyle" TargetType="{x:Type Button}">
    <Setter Property="Template">
       <Setter.Value>
          <ControlTemplate TargetType="{x:Type Button}">
             <Border x:Name="border" BorderBrush="{TemplateBinding Property=BorderBrush}" BorderThickness="{TemplateBinding Property=BorderThickness}" Background="{TemplateBinding Property=Background}">
                <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
             </Border>
          </ControlTemplate>
       </Setter.Value>
    </Setter>
</Style>

And apply this style like:

<Grid>
    <Button Name="btnNew" Style="{StaticResource ButtonStyle }" Width="200" Height="50" Click="Button_Click" />
</Grid>

After that you can change those property of Border as your wish, For example:

btnNew.Background = Brushes.Black;
btnNew.BorderThickness = new Thickness(4, 5, 7, 9);
btnNew.BorderBrush = Brushes.Red;

But it does not look like button's border thickness is 1, I would say it looks like it's 3 or smth, thats reason why I want to set it up to 1, I will post screenshot later and you will see what I am talking about :)

The default button in WPF has a border property, no need to add it (msdn.microsoft.com/en-us/library/…)

Definitely @91378246 , Button class has a property named Border , But I am talking about Template. ContentPresenter is the thing which is responsible for any content with in button and that ContentPresenter don't have Border so for change Border thickness first you have to add it and the easiest way is wrap ContentPresenter inside a Border and play with it like I did it above. There can be other way but This is what I found easy.
