Setting the Style property of a WPF Label in code?

Question

In App.xaml, I have the following code:

<Application.Resources>     <Style x:Key="LabelTemplate" TargetType="{x:Type Label}">         <Setter Property="Height" Value="53" />         <Setter Property="Width" Value="130" />         <Setter Property="HorizontalAlignment" Value="Left" />         <Setter Property="Margin" Value="99,71,0,0" />         <Setter Property="VerticalAlignment" Value= "Top" />         <Setter Property="Foreground" Value="#FFE75959" />         <Setter Property="FontFamily" Value="Calibri" />         <Setter Property="FontSize" Value="40" />     </Style> </Application.Resources> 

This is meant to provide a generic template for my labels.

In the main XAML code, I have the following line of code:

<Label Content="Movies" Style="{StaticResource LabelTemplate}" Name="label1" /> 

However, I'd like to initialize the Style property through code. I have tried:

label1.Style = new Style("{StaticResource LabelTemplate}"); 

and

label1.Style = "{StaticResource LabelTemplate}"; 

Neither solution was valid.

Any help would be appreciated :).

Answer 1

Where in code are you trying to get the style? Code behind?

You should write this:

If you're in code-behind:

Style style = this.FindResource("LabelTemplate") as Style; label1.Style = style; 

If you're somewhere else

Style style = Application.Current.FindResource("LabelTemplate") as Style; label1.Style = style; 

Bottom note: don't name a Style with the keyword Template, you'll eventually end up confusing a Style and a Template, and you shouldn't as those are two different concepts.

Please check for null style result or you will be sad... ... if (style != null) this.Style = style;
