I'm trying to use this nuget package but I've got a problem with the ColorWheel.
When the initial value of the SelectedColor is black(Color.FromHex("#FF000000")) and I use the the colorpicker to set a new value my property in the viewmodel isn't updated.
When I first set my property to another color and then update via the colorwheel my setter is triggerd
Viewmodel property:

   public Color EditedColor1
        {
            get { return _editedColor1; }
            set
            {
                _editedColor1 = value;
                Settings.AddOrUpdateValue("color1", _editedColor1.ToHex());
                RaisePropertyChanged(() => EditedColor1);
                ColorChanged(1);
            }
        }

View

<colorPicker1:ColorWheel Grid.Row="2" Grid.Column="0" x:Name="ColorWheel1" VerticalOptions="FillAndExpand"
                                    ShowAlphaSlider="False"
                                    ShowLuminositySlider="False"
                                    ShowLuminosityWheel="False" SelectedColor="{Binding EditedColor1, Mode=TwoWay}" PropertyChanged="ColorWheel1_OnPropertyChanged"
                                    />

I didn't use the nuget package itself because I'm using a newer version of Xamarin forms so I downloaded your code updated the package and used that dll.

With the slides the problem doesn't occur.

When I try to install this package through NuGet, it fails with the complaint that it's not compatible with NetStandard.Library 2.0 and that I need 2.1

The only issue is that there's no 2.1 NetStandard.Library available to me.
I'm on the latest release of that package and that's 2.0.3

Here's a screen showing that I can't update my version any higher
https://drive.google.com/open?id=15WOeztPKYt-MfhZPLIhBc_3YUrGJekkZ

and here's the package requiring 2.1
https://drive.google.com/open?id=1UVytQ7jorgePWdn54E7qyS-v8Jl4ZqpI

and I'm using Visual Studio Community 2017 on Windows 10 Pro

Is there anything I have to do to be able to get NetStandard.Library 2.1?

I am irked that the WINUI 3 ColorPicker is so complex and not easy to use in C# code.

I would much prefer a more straightforward implementation such as provided by this project, although I do realize that a new implementation would require creating a Handler rather than a custom Renderer.

One desirable feature enhancement would be to allow specification of, and the display of,a hex value, e.g. #rrggbbaa
with alpha, or #rrggbb without alpha (would default to 100%)

Something is wrong when the color picker is child element of TabViewItem(control -> Xamarin Community Toolkit TabView).
https://docs.microsoft.com/en-us/xamarin/community-toolkit/views/tabview

The color picker becomes transparent, but the color selection is still available.
You can swipe and see the selected color is changing.
I attached the sample which shows the issue.

Steps to reproduce the behavior:

1. Open the sample app(TestApp.Android).
2. Click on 'Tab 2.'
3. Click on 'Tab 1.'
4. See error

Expected behavior
The Color picker must be visible and displayed.

Hi,

I'm using the ColorPicker on a multi-target. On android all works fine but on IOS the sliders of the picker not works. When I try to move them, they don't move.

Can someone who had this issue help me ?
Or is this working for someone on IOS ?

Thanks.

Describe the bug
Unable to generate the release build, when we try to build for Processor architecture x64 & ARM

To Reproduce
Steps to reproduce the behavior:

1. Create a new Xamarin Forms project that supports UWP.
2. Add Color Picker Plugin
3. Try to generate the release build with Processor architecture x64 / ARM

Expected behavior
The app should generate UWP release build for x86, x64 & ARM without any issue.

Is your feature request related to a problem? Please describe.
Doesn't support UWP

Describe the solution you'd like
Please include UWP

Describe alternatives you've considered

Additional context
I think it would be very easy to add UWP as skiasharp is fully supported in UWP.

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Put the colorpicker inside a scrollview
2. Try to select color from the traingle
3. Now observe the behavior
4. See it is not smooth and having difficulty setting a color

Expected behavior
Scroll view "OnScrolled" event should be disabled

Desktop (please complete the following information):

• OS: iOS, Adnroid

Describe the bug
UWP app started to crash after updating the Xamarin Forms app to the latest Xamarin Forms version.

Upon Further analysis on the issue, it is identified that when ColorPicker NuGet Package is installed, it adds SkiaSharp (1.60.3) as a dependency, and the app works without any issue

SkiaSharp version gets updated, When adding/installing another NuGet package that contains a reference to higher SkiaSharp version.

As a result app crash, when the SkiSharp version gets updated to 2.80.2 from 1.60.3.

Expected behavior
App Should work without crashing.

To Reproduce
Steps to reproduce the behavior:

1. Download Color Picker Sample from https://github.com/vpapenko/ColorPicker.Nuget.Test
2. Install any one NuGet package, which has a higher version of SkiaSharp depedency. example: Syncfusion.Xamarin.DocIORenderer
3. Run the app

This code can be deleted

as is handled by the base class

I'm using FreshMVVM and the master detail navigation container. This seems to cause an issue when the colorpicker is in a detail view (iOS only). Pressing on a new location works fine but dragging the selected circle causes the wheel to freeze. I'm guessing it's due to the fact you can slide to open the menu

Ideally the colorpicker would work in the detail view

I can create a sample project if that would help

I am trying to build a app, where you get a preview of the current settings. DataBinding is not an option here.

Would it be possible, to add a ColorChanged Event, similar to the TextChanged/ Pressed Events of the Entry/ Button Class?

like:<Button Pressed="ButtonPressedEvent"/>
->
<ColorCircle ColorChanged="ColorChangedEvent"

Describe the bug
Dragging the sliders on the controls on iOS will move the slider a small amount and then stop. Afterwards no further interaction (pressing or sliding) will move the slider.

To Reproduce
Steps to reproduce the behavior:

1. Add a HSLSliders control to NavigationPage(I've tried both TabbedPage and ContentPage, both within a FlyoutPage)
2. Slide the circular slider on the control
3. After releasing (or it stops moving) try sliding it again or pressing elsewhere on the control
4. No further interaction happens

Expected behavior
The slider should move to the tapped location, or be able to moved via pressing and sliding

Smartphone (please complete the following information):

• Device: iPhone SE
• OS: iOS 14.8.1
• Version: 1.3.4.21
• Xamarin Forms: 5.0.0.2291

Additional context
Also, trying to slide any of the sliders to the right just instead results in the flyout page menu being displayed.

I'm trying to create a multiple-targeting library for Xamarin(Android, IOS and UWP.) I examined project files of some multi-targeting xamarin libraries. (Such as Rg.Plugins.Popup, Xamarin.Essentials, MvvmCross) and edited the csproj file of my library(XamTemel.Ortak) like this.

<Project Sdk="MSBuild.Sdk.Extras/3.0.22"> <PropertyGroup> <TargetFrameworks>netstandard2.0;Xamarin.iOS10;monoandroid10.0;</TargetFrameworks> <TargetFrameworks Condition=" '$(OS)' == 'Windows_NT' ">$(TargetFrameworks);uap10.0.17763;</TargetFrameworks> <DebugType>portable</DebugType> <Configurations>Debug;Release</Configurations> </PropertyGroup> <PropertyGroup Condition=" '$(Configuration)'=='Debug' "> <DebugSymbols>true</DebugSymbols> </PropertyGroup> <PropertyGroup Condition=" '$(Configuration)'=='Release' And '$(OS)' == 'Windows_NT' "> <!-- sourcelink: Declare that the Repository URL can be published to NuSpec --> <PublishRepositoryUrl>true</PublishRepositoryUrl> <!-- sourcelink: Embed source files that are not tracked by the source control manager to the PDB --> <EmbedUntrackedSources>true</EmbedUntrackedSources> <!-- sourcelink: Include PDB in the built .nupkg --> <AllowedOutputExtensionsInPackageBuildOutputFolder>$(AllowedOutputExtensionsInPackageBuildOutputFolder);.pdb</AllowedOutputExtensionsInPackageBuildOutputFolder> </PropertyGroup> <ItemGroup> <Compile Remove="Platforms\**\*.cs" /> <None Include="Platforms\**\*.cs" /> </ItemGroup> <ItemGroup Condition=" $(TargetFramework.StartsWith('monoandroid')) "> <None Remove="Platforms\Android\**\*.cs" /> <None Remove="Platforms\Xamarin\**\*.cs" /> <Compile Include="Platforms\Android\**\*.cs" /> <Compile Include="Platforms\Xamarin\**\*.cs" /> <AndroidResource Include="Resources\**\*.xml" SubType="Designer" Generator="MSBuild:UpdateAndroidResources" /> <AndroidResource Include="Resources\**\*.json" Generator="MSBuild:UpdateAndroidResources" /> </ItemGroup> <ItemGroup> <PackageReference Include="ColorPicker.Xamarin.Forms" Version="1.3.4.11" /> </ItemGroup> </Project>

As you can see I am going to put platform renderers in Platform/Android-IOS-UWP etc. Not this works fine on Android. But ColorPicker library gives me this error on UWP.

I don't understand why it cannot find ColorPicker. Version number seems okay. What am I doing wrong?

Here is the sample solution.

Describe the bug
When I try to bind the SelectedColor to a ViewModel class it gets the value, but won't set it

To Reproduce
Steps to reproduce the behavior:

1. Create a project and get ColorPicker all set up according to instructions
2. Add using Xamarin.Forms ViewModel binding by using the BindingContext in the xaml
3. Add a property to the ViewModel of type Xamarin.Forms.Color with a get and set
4. Add a ColorPicker to the xaml and use standard binding format to bind it to the view model property
5. Run the project and change the color on the color wheel

Expected behavior
I would expect my view model property SET to be called any time the color changes.

Desktop (please complete the following information):

• OS: iOS
• Version: Latest

Additional context
If I change my xaml to be similar to the TestApp project so that another control in the xaml uses a reference binding then it work, but only if I remove my binding to my view model property. If they are both there, then neither one updates.

Note that when I have my view model binding in place and I set a break point in the GET of my property it does hit it and retrieves the color just fine.

Here is my xaml:

<StackLayout Orientation="Vertical" BackgroundColor="{Binding Source={x:Reference LabelColorWheel}, Path=SelectedColor}">
<colorpicker:ColorCircle x:Name="LabelColorWheel" SelectedColor="{Binding LabelColor}"/>
</StackLayout>

Here is my view model:

private Color _labelColor;
public Color LabelColor
{
get { return _labelColor; }
set
{
if (_labelColor != value)
{
_labelColor = value;
SafePropertyChanged("LabelColor");
}
}
}

I am sorry my formatting isn't very good. It doesn't seem to paste code like I expect.
