A class library project showcasing .NET MAUI version of the Bootstrap web component library.
One of the most useful libraries I have seen for C# only MAUI developers.
In your MauiProgram.cs file CreateMauiApp() method
[DEPRECATED]
builder.UseMauiBootstrap("REGULAR_FONT_FAMILY_NAME", "BOLD_FONT_FAMILY_NAME");
builder.UserMauiBootstrap(); // use this one instead. In your App.cs file constructor
using MAUIBootstrap.Resources.Styles;
..
Resources.Add(new BootstrapColors());
Resources.Add(new BootstrapStyles());
protected override Window CreateWindow(IActivationState? activationState)
{
...
// set your custom fonts here.
// where Constants.RegularFont is the string you set in MauiProgram.cs
// when registering the font initially.
MAUIBootstrap.DynamicConstants.Instance.RegularFont = Constants.RegularFont;
MAUIBootstrap.DynamicConstants.Instance.BoldFont = Constants.MediumFont;
...
return new Window(new NavigationPage(new ControlsPage()));
}The above will set up everything needed to use the class library.
The MAUI.Bootstrap library has basic dark/mode light mode theming available for you to use.
// toggle theme
var themeButton = new Button()
.Text("Toggle Theme")
.Danger()
.OnClicked((s, e) => {
switch (BootstrapColors.CurrentTheme)
{
case AppTheme.Dark:
BootstrapColors.CurrentTheme = AppTheme.Light;
break;
case AppTheme.Light:
BootstrapColors.CurrentTheme = AppTheme.Dark;
break;
}
});Anything inside BootstrapColors.xaml binding to DynamicResource will be adjusted on the fly. You can add more resource dictionaries to your app and bind them to any of the bootstrap colors.
You may also change available bootstrap colors on the fly as well.
// change page color to Pink
var pinkPage = new Button()
.Text("Set Page Color To Pink")
.Info()
.OnClicked((s,e) => {
BootstrapColors.PageColor = Colors.Pink;
});All available colors that can be changed on the fly are accessible via C# BootstrapColors class.
