Xamarin Forms Picker in MVVM

[@rohanandgwen1221]

Tried so many eventhandlers, this was the only one that worked for me, thanks!!

[@robertsalasidis7695]

Excellent video. Only change I had to make was adding a foreach with a List.Add for dynamically adding the elements in the Picker at runtime. Worked on the first shot

glad to hear that it is helpful for you.. :)

[@nicoseaton4567]

Impressive how complicated this is in Xamarin. Thank you for this tutorial. I miss windows forms C# where it was as simple as Dropdown.content.

[@c_forcoding]

cool :)

Cities not showing in the picker when I open the app. Like at 2:56 mark. It shows blank.

[@c_forcoding]

May be some data binding issue.. please check your code once

How to select all items in xamarin?

[@shanmuhammad3818]

how to set a value by default in picker in mvvm

[@c_forcoding]

Set selectedItem to the default value, it will work.. like SelectedCity = CitiesList[1]; in the constructor

Thank you, I have a question. Already my project has MainPage. Example: "MainPage = new NavigationPage(new Page1());" this is the root page; how can i add page for picker,
for example I applied the picker in Page5() Example: "MainPage = new NavigationPage(new Page5());"

[@c_forcoding]

I didn't understand your question clearly...
If you mean navigating to a page on button click:
await Navigation.PushAsync (new Page5());

[@shurooqaldaja912]

@@c_forcoding Thank you for response, NO need a button. when I applied your code in the same steps. it gave error.
Can not resolve reference: `System.Diagnostics.PerformanceCounter`, referenced by `Microsoft.VisualStudio.Telemetry`. Please add a NuGet package or assembly reference for `System.Diagnostics.PerformanceCounter`, or remove the reference to `Microsoft.VisualStudio.Telemetry`.
But, already 'System.Diagnostics.PerformanceCounter' NuGet package installed. In my project the NavigationPage (root) in App.xml.cs is "MainPage = new NavigationPage(new Page1());"

[@c_forcoding]

@@shurooqaldaja912 This seems to be a project setup issue.. create a new project and try implementing Picker

[@stephanraab3648]

Add that logic on the "SelectedItem" event

[@cguajardo]

Thanks,How the picker selection is cleaned?

[@c_forcoding]

Set SelectedItem to NULL.. It clears the SelectedItem

[@EleazarJSH]

I'm learning Xamarin and would like to know how to populate the picker with data from an Enum from Item.
public class Item
{
public string Id { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public bool Done { get; set; }
public ItemType ItemType { get; set; }
public ItemPriority ItemPriority { get; set; }
}
public enum ItemType
{
Personal, Professional
}
public enum ItemPriority
{
High, Low
}
