Problem with button designs. MaterialDesign, c#, wpf-CodePudding

My problem would be, I want to make a menu with MaterialDesign and I want the button style to change when I go to one of the menu items in the menu. However, when I overwrite the MaterialDesign style, I cannot reset it. I wanna make somethin like like this:enter image description here

Thats my menu code:

    <Grid>
        <StackPanel Orientation="Horizontal" Height="35" VerticalAlignment="Top" >
            <Button x:Name="User_B"  Content="Users" MinWidth="100" Click="User_B_Click"/>
            <Button x:Name="Auto_B" Content="Auto" MinWidth="100" Click="Auto_B_Click"/>
            <Button x:Name="Clien_B" Content="Client" MinWidth="100" Click="Clien_B_Click" />
            <Button x:Name="Failure_B" Content="Failure" MinWidth="100" Click="Failure_B_Click"/>
            <Button x:Name="Settings_B" Content="Settings" MinWidth="100" Click="Settings_B_Click"/>
        </StackPanel>
        <Frame x:Name="Main" Margin="0,35,0,0" NavigationUIVisibility="Hidden"/>
    </Grid>

My c# code:

 private void User_B_Click(object sender, RoutedEventArgs e)
        {
            Style selectstyle = new Style();
            selectstyle.TargetType = typeof(Button);
            selectstyle.Setters.Add(new Setter(Button.BackgroundProperty, new SolidColorBrush((Color)ColorConverter.ConvertFromString("#303030"))));
            selectstyle.Setters.Add(new Setter(Button.ForegroundProperty, new SolidColorBrush((Color)ColorConverter.ConvertFromString("#d50000"))));
            User_B.Style = selectstyle;
            Auto_B.Style = null;
        }

        private void Auto_B_Click(object sender, RoutedEventArgs e)
        {
            Style selectstyle = new Style();
            selectstyle.TargetType = typeof(Button);
            selectstyle.Setters.Add(new Setter(Button.BackgroundProperty, new SolidColorBrush((Color)ColorConverter.ConvertFromString("#303030"))));
            selectstyle.Setters.Add(new Setter(Button.ForegroundProperty, new SolidColorBrush((Color)ColorConverter.ConvertFromString("#d50000"))));
            Auto_B.Style = selectstyle;
            User_B.Style = null;
        }

and this is how it looks now:enter image description here

CodePudding user response：

First you need to do this in all of your pages :

MainWindow mw = null;
    public Employees(MainWindow mw)
    {
        InitializeComponent();
        this.mw = mw;
    }

Create a null object for your MainWindow , than give a parameter to your Page method , then in the method , you declare the MainWindow like I show you in the code.

After you done with this , then you need to go to the MainWindow.xaml.cs and you have to do this:

public MainWindow()
    {
        InitializeComponent();
        employees = new Employees(this);
        Presenter.Content = employees;
    }

    Employees employees = null;

Create a null object for your Page , and in the MainWindow method you have to declare the Page like this.

After that , you just need a Loaded and an Unloaded event to your page :

private void Page_Loaded(object sender, RoutedEventArgs e)
    {
        mw.EmployeesButton.Background = (Brush)new BrushConverter().ConvertFrom("#006B60");
    }

    private void Page_Unloaded(object sender, RoutedEventArgs e)
    {
        mw.EmployeesButton.Background = (Brush)new BrushConverter().ConvertFrom("#009688");
    }

You can use any color you want , I hope its helps :D
