what is the best way to set same background color all button in the ma

Hello Meghan, Its preety simple, could you try below uisng xaml code. There are two ways to do it using StaticResources and DynamicResources. Please read it when to use which one. In below code using static resources you can set in Windows.Resources, Application.Resources(In App.xaml file) and control level like Grid.Resources.

Static Resoures Example:

XAML Code:

<Window x:Class="WpfResources.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfResources"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Window.Resources>
Window.Resources>
<Grid>
<Grid.Resources>
<SolidColorBrush Color="Red" x:Key="ButtonColorRed">
SolidColorBrush>
Grid.Resources>
<Button Width="200" Height="100" Margin="47,68,553,266"
Background="{StaticResource ButtonColorRed}" >Button>
<Button Width="200" Height="100" Margin="332,90,268,244"
Background="{StaticResource ButtonColorRed}" >Button>
<Button Width="200" Height="100" Margin="200,276,400,58"
Background="{StaticResource ButtonColorRed}" >Button>
Grid>
Window>

Dynamic Resources example:

XAML Code:

<Window x:Class="WpfDynamicResources.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfDynamicResources"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<Grid>
<Button Width="200" Height="100" Margin="10,60,590,274" Background="{DynamicResource DynamicColor}">Button>
<Button Width="200" Height="100" Margin="530,60,70,274" Content="Set Red Color" FontSize="30" Name="btnSetRed" Click="btnSetRed_Click">Button>
<Button Width="200" Height="100" Margin="530,217,70,117" Content="Set Blue Color" FontSize="30" Name="btnSetBlue" Click="btnSetBlue_Click">Button>
Grid>
Window>

C# Code:

using System.Windows;
using System.Windows.Media;
namespace WpfDynamicResources
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void btnSetRed_Click(object sender, RoutedEventArgs e)
{
this.Resources["DynamicColor"] = new SolidColorBrush(Colors.Red);
}
private void btnSetBlue_Click(object sender, RoutedEventArgs e)
{
this.Resources["DynamicColor"] = new SolidColorBrush(Colors.Blue);
}
}
}
