eventbinder's Issues

Support .NET Core 3+

[Duplicate #59][Dumb question] How can I use it ?

It's said in getting started:

Just install the nuget package. If it does not work and you get XamlParseException, then apply [assembly: EventBinder.AssemblyReference] attribute in your AssemblyInfo.cs.

Ok, I have the Exception, and, that's all. How can I add this assembly reference ? Maybe related to #59. If so, I will wait then.

Thanks.

Edited for more Info:

xmlns:e="using:EventBinder" works. But Exception at {e:EventBinding...}
'Could not load file or assembly 'Avalonia.Visuals, Version=0.9.12.0, Culture=neutral, PublicKeyToken=null'. Le fichier spécifié est introuvable.'
So it's a duplicate issue.

Event binding in code behind

Provide some way to bind outside of xaml, something like EventBinding.Bind

Avoid multiple bindings

There could be an issue with Avalonia
There could be an issue when we change a VM to another one

Binded method doesn't work after control reloading

Support empty Path property for binded arguments with and without ElementName

Issue with binding to the same event of different control types (Avalonia)

I'm running into an issue when binding to the same event of different controls. I am binding to the Initialized event of multiple controls. When I do so, I get a System.MissingMethodException 'Constructor on type' with a long hex code.

This error is repeated with any Event type that I've tried. (Initialize, AttachedToVisualTree, PointerPressed)

If the controls are all of the same type or if I bind to a different event for each different control, I do not have this issue. It only occurs when binding to the same event of different control types.

Support for Avalonia v11-preview

Hi, it would be nice if you could add support for v11-preview in a preview nuget package, it would only require a version change of Avalonia to a v11-preview. It does need a new build because there is a binary breaking change from pre v11 to v11.

Internal Compiler Error: Could not load Avalonia.Visuals, Version = 0.9.0.0

I recently upgraded my project from Avalonia version 0.10.13 to version 11.1.1. With this change any AXAML page that uses event binder throws the following error where it is trying to reference Avalonia.Visuals v 0.9.0.0.

In the solution explorer the package throws no errors or warnings.

Has anyone seen this issue before or have ideas on what I can check?

Actions Completed:

Removed all nugget packages and re-installed them
- I work in an offline environment so I just download all of the packages required via nuget.exe
Ran dotnet restore on the solution
Problem isolated to only appear when AXAML page has event binding

Support nested method path

Add support for paths like this "NestedObj.NestedObj.MyMethod"

EventBinder fails on KeyDown event in WPF - .NET 5.0

Hi @Serg046, thanks for a great tool! I run into an Exception when trying to bind to the KeyDown event (and many other events) in my .NET 5 wpf app. See image for the location in the code where it fails in EventBinding.cs (I changed the code slightly for simpler display of nullvalue) :

The event TextChanged or MouseLeftButtonDown works fine. Here's my xaml:

Any idea on how to fix, or if I'm doing something wrong?

Support for binding commands and not just methods?

Would be a nice feature for consistency with the command pattern.

Support implicit conversion from value types to reference types

The following code crashes because value types should be boxed before passing:

var button = XamlReader.Parse<Button>($"<Button Height=\"{expected}\" Name=\"Btn\" Click=\"{{e:EventBinding Invoke, {{Binding ElementName=Btn, Path=Height}}}}\"/>");
button.DataContext = new Action<object>(n => num = (double)n);

Support Path property for binded arguments without ElementName

Constructions like this should be supported

{EventBinding Method, {Binding SomeProp}}

DRY: extract and re-use the lib version

Remove unnecessary boxing

Rewrite the following method so that it will be generic without boxings

internal static object ResolveBinding(Binding binding, FrameworkElement source, int position)
{
	if (!BindingOperations.IsDataBound(source, _properties[position]))
	{
		BindingOperations.SetBinding(source, _properties[position], binding);
	}
	return source.GetValue(_properties[position]);
}

public void M() {
    int a = 6;
    Test(a, "");
}
    
public void Test(double x, string y) {}

The construction above compiles to this

        IL_0000: ldc.i4.6
        IL_0001: stloc.0
        IL_0002: ldarg.0
        IL_0003: ldloc.0
        IL_0004: conv.r8
        IL_0005: ldstr ""
        IL_000a: call instance void C::Test(float64, string)

Add support for such conversions

Support Delay binding property

Such stuff should be available https://bartwullems.blogspot.com/2017/07/wpf-debounce-trick.html

Improve handlers caching

Now the cache is based on type, method and arguments. It seems that caching based on type only is more efficient. Investigate this option (method and arguments can be passed at runtime).
