# Key Features
|
||||
|
||||
The purpose of this help article is to show you the key features of the Templated(Custom) Picker control for Xamarin.
|
||||
|
||||
## DisplayMemberPath
|
||||
|
||||
Its purpose is to specify a property of the source object to serve as the visual representation of the spinner item.
|
||||
|
||||
## DisplayStringFormat
|
||||
|
||||
You can choose what text to display when an item from the spinner was picked through the Picker DisplayStringFormat property. For more info on this check the Key Features - Display String section.
|
||||
|
||||
## SelectedValue
|
||||
|
||||
The SelectedValue property is used when you have linked your RadTemplatedPicker to a data source, and you want to return a value of type object other than the one which is displayed.
|
||||
|
||||
## Example
|
||||
|
||||
Here is a sample example which shows how the *SelectedValue* and *DisplayMemberPath* can be used:
|
||||
|
||||
<snippet id='templatedpicker-keyfeatures' />
|
||||
|
||||
Here is a sample definition of the SelectorTemplate:
|
||||
|
||||
<snippet id='templatedpicker-keyfeatures-selectortemplate' />
|
||||
|
||||
and for the HeaderTemplate:
|
||||
|
||||
<snippet id='templatedpicker-keyfeatures-headertemplate' />
|
||||
|
||||
add the following Business model for the first spinner:
|
||||
|
||||
<snippet id='templatedpicker-country-businessmodel' />
|
||||
|
||||
add the following Business model for the second spinner:
|
||||
|
||||
<snippet id='templatedpicker-city-businessmodel' />
|
||||
|
||||
here is a sample definition of the ViewModel:
|
||||
|
||||
<snippet id='templatedpicker-viewmodel' />
|
||||
|
||||
In addition to this, you need to add the following namespace:
|
||||
|
||||
```XAML
|
||||
xmlns:telerikInput="clr-namespace:Telerik.XamarinForms.Input;assembly=Telerik.XamarinForms.Input"
|
||||

# Styling
|
||||
|
||||
Using the SelectorSettings property of the RadPickerBase class, you could style the dialog(popup) through the following properties:
|
||||
|
||||
* **PopupViewStyle**(of type *Style* with target type is **telerikInput:PickerPopupContentView**):
|
||||
* **HeaderStyle**(of type *Style* with target type is **telerikInput:PickerPopupHeaderView**):
|
||||
* **HeaderLabelStyle**(of type *Style* with target type is **Label**):
|
||||
* **FooterStyle**(of type *Style* with target type is **telerikInput:PickerPopupFooterView**):
|
||||
* **AcceptButtonStyle**(of type *Style* with target type is **Button**):
|
||||
* **CancelButtonStyle**(of type *Style* with target type is **Button**):
|
||||
|
||||
The SelectorSetting also provides the following properties for popup customization:
|
||||
|
||||
* **PopupOutsideBackgroundColor**(*Xamarin.Forms.Color*): Defines the color outside of the popup.
|
||||
* **HeaderLabelText**(*string*): Specifies the text visualized in the popup header.
|
||||
* **AcceptButtonText**(*string*): Defines the text visualized for the accept button. By default the text is *OK*.
|
||||
* **CancelButtonText**(*string*): Defines the text visualized for the cancel button. By default the text is *Cancel*.

# Templates
|
||||
|
||||
Templated Picker for Xamarin provides the following template:
|
||||
|
||||
* **SelectorTemplate**(*ControlTemplate*): Defines the template used for displaying the selector of the picker.
|
||||
|
||||
In addition to this you can define the following templates provided from the RadPickerBase class:
|
||||
|
||||
* **PlaceholderTemplate**(*ControlTemplate*): Defines the template visualized for the placeholder.
|
||||
* **DisplayTemplate**(*ControlTemplate*): Defines the template visualized when the picked date/time is displayed.
|
||||
|
||||
And using RadPickerBase.SelectorSettings property(of type *Telerik.XamarinForms.Input.PickerPopupSelectorSettings*) you can define the following templates:
|
||||
|
||||
* **HeaderTemplate**(*ControlTemplate*): Defines what will be displayed inside the dialog(popup) header.
|
||||
* **FooterTemplate**(*ControlTemplate*): Defines what will be displayed inside the dialog(popup) footer.
|
||||
|
||||

|

|

## Description
|
||||
|
||||
This article shows how to deserialize appointment objects from JSON.
|
||||
|
||||
## Solution
|
||||
|
||||
First, download NuGet packages for NewtonSoft library. More information about NewtonSoft can be found [here](https://www.newtonsoft.com/json).
|
||||
|
||||
Create new JSON file with name "Source.json" to our project and change its Build Action to "Embedded resource".
|
||||
|
||||
Here is a sample how our JSON file is stuctured.
|
||||
|
||||
```JSON
|
||||
[
|
||||
{
|
||||
"Title": "Meeting with Tom",
|
||||
"Detail": "Sea Garden",
|
||||
"StartDate": "2019-10-07T00:00:00Z",
|
||||
"EndDate": "2019-10-07T01:00:00Z",
|
||||
"Color": "Red",
|
||||
"IsAllDay": true
|
||||
},
|
||||
{
|
||||
"Title": "Lunch with Sara",
|
||||
"Detail": "Restaurant",
|
||||
"StartDate": "2019-10-08T00:00:00Z",
|
||||
"EndDate": "2019-10-08T01:00:00Z",
|
||||
"Color": "Blue",
|
||||
"IsAllDay": true
|
||||
},
|
||||
{
|
||||
"Title": "Elle Birthday",
|
||||
"StartDate": "2019-10-09T00:00:00Z",
|
||||
"EndDate": "2019-10-09T01:00:00Z",
|
||||
"Color": "Green",
|
||||
"IsAllDay": false
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
Add the RadCalendar in the Main.xaml file.
|
||||
|
||||
```XAML
|
||||
<telerikInput:RadCalendar x:Name="calendar"/>
|
||||
```
|
||||
|
||||
After that lets create a class that will convert inconsistent JSON data like Colors.
|
||||
|
||||
```C#
|
||||
public class AppointmentJsonConverter : JsonConverter<Appointment>
|
||||
{
|
||||
public override Appointment ReadJson(JsonReader reader, Type objectType, Appointment existingValue, bool hasExistingValue, JsonSerializer serializer)
|
||||
{
|
||||
JObject jObject = JObject.Load(reader);
|
||||
var title = jObject["Title"].Value<string>();
|
||||
String detail = null;
|
||||
if (jObject["Detail"] != null)
|
||||
{
|
||||
detail = jObject["Detail"].Value<string>();
|
||||
}
|
||||
|
||||
var startDate = jObject["StartDate"].Value<DateTime>();
|
||||
var endDate = jObject["EndDate"].Value<DateTime>();
|
||||
|
||||
var colorTypeConverter = new ColorTypeConverter();
|
||||
var color = (Color)colorTypeConverter.ConvertFromInvariantString(jObject["Color"].Value<string>());
|
||||
|
||||
return new Appointment()
|
||||
{
|
||||
Title = title,
|
||||
Detail = detail,
|
||||
StartDate = startDate,
|
||||
EndDate = endDate,
|
||||
Color = color
|
||||
};
|
||||
}
|
||||
|
||||
public override void WriteJson(JsonWriter writer, Appointment value, JsonSerializer serializer)
|
||||
{
|
||||
throw new NotImplementedException();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Finally, create a method named "GetJsonData()" which uses NewtonSoft library and deserializes the appointment objects in it.
|
||||
|
||||
```C#
|
||||
public partial class MainPage : ContentPage
|
||||
{
|
||||
public MainPage()
|
||||
{
|
||||
InitializeComponent();
|
||||
this.GetJsonData();
|
||||
}
|
||||
|
||||
private void GetJsonData()
|
||||
{
|
||||
string jsonFileName = "Source.json";
|
||||
ObservableCollection<Appointment> objAppointmentList = new ObservableCollection<Appointment>();
|
||||
var assembly = typeof(MainPage).GetTypeInfo().Assembly;
|
||||
Stream stream = assembly.GetManifestResourceStream($"{assembly.GetName().Name}.{jsonFileName}");
|
||||
using (var reader = new System.IO.StreamReader(stream))
|
||||
{
|
||||
var jsonString = reader.ReadToEnd();
|
||||
objAppointmentList = JsonConvert.DeserializeObject<ObservableCollection<Appointment>>(jsonString, new AppointmentJsonConverter());
|
||||
}
|
||||
this.calendar.AppointmentsSource = objAppointmentList;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
