Controls

BindablePicker

BindablePicker inherits from Xamarin.Forms.Picker, you can binding data to ItemSource as Items, and also can set which property you want to display via DisplayProperty.

If you want to use it in XAML, you need to include the namespace first

xmlns:fe="clr-namespace:FreshEssentials;assembly=FreshEssentials"

Then

<fe:BindablePicker ItemsSource="{Binding MyCars}" SelectedItem="{Binding SelectedCar}" DisplayProperty="MakeAndModel" Title="Select..." />

AdvancedFrame (flexible rounded corners)

AdvancedFrame inherits from Frame, you can set corner type via Corners(There are only four type, left, right, all, none), you can also set CornerRadius and InnerBackground color

<fe:AdvancedFrame Corners="left" CornerRadius="10" InnerBackground="Blue" OutlineColor="Red" >
	<Label Text="Corners is left, CornerRadius is 10, InnerBackground is Blue" TextColor="White"/>
</fe:AdvancedFrame>

SegmentedButtonGroup

SegmentedButtonGroup is like iOS Segmented Controls, you can binding SelectedIndex for it

<fe:SegmentedButtonGroup OnColor="Blue" OffColor="White" SelectedIndex="{Binding SelectIndex, Mode=TwoWay}">
	<fe:SegmentedButtonGroup.LabelStyle>
		<Style TargetType="Label">
		    <Setter Property="FontSize" Value="12" />
			<Setter Property="FontAttributes" Value="Bold" />
		</Style>
	</fe:SegmentedButtonGroup.LabelStyle>
	<fe:SegmentedButtonGroup.SegmentedButtons>
		<fe:SegmentedButton Title="Button 1"/>
		<fe:SegmentedButton Title="Button 2"/>
