I wrote a Windows Phone 8.1 (WINRT) App. I need to show Calendar in the page. So, I added WinRT XAML Toolkit - Calendar Control from nuget.
PM> Install-Package WinRTXamlToolkit.Controls.Calendar
<Page
x:Class="DrFit.Pages.ActivityTimeTablePage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:DrFit.Pages"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
xmlns:WinRT="using:WinRTXamlToolkit.Controls"
Background="Black">
<Grid x:Name="LayoutRoot">
<WinRT:Calendar Height="500">
</WinRT:Calendar>
</Grid>
</Page>
How to Customise this Calendar control, example FontWeight,Foreground,Background?
If the properties aren't exposed by the control or template-bound to template part properties - you'll probably need to change the template. You can find the default template here and templates for calendar parts are in the same folder:
WinRTXamlToolkit.Controls.Calendar/WinRTXamlToolkit.Controls.Calendar.Shared/Controls/Calendar
