Using DynamicResources in WPF

DynamicResource: DynamicResources are resolved at runtime. Use DynamicResources when the value of the resource could change during the lifetime of the Application.

I will show you an example regarding DynamicResource.

<Window.Resources>

</Style>

</Window.Resources>

In my WPF application page I've one textbox and two ellipses. In Window.Resources I defined the SolidColorBrush and the Style properties.

In above code you can observe x: Key attribute. x: Key uniquely identifies elements that are created and referenced in a XAML-defined dictionary.

Here I'm using above resources. Have a look at below code.

You can use this syntax in xaml design page: {DynamicResource x:keyName}

<Grid>

</DockPanel>

</Border>

</StackPanel>

</Grid>

And in code behind page (.xaml.cs), I write this code in button click event.

private void Button_Click(object sender, RoutedEventArgs e)

{

this.button.SetResourceReference(BackgroundProperty, "brush");

}

Run the page and you can see the color change of the button after you click on it.

Result window looks like this.

In my very next article, I will explain you about DynamicResource with Animation.
