Xamarin Mac application - Calling C# code from the WebView event or through Javascript

Sandeep Vaidya 6

I have a requirement to call back C# code from the Javascript of the Html loaded on the WebView. I used the customize WebView code to add additional method to register call back which is working fine on Windows, however the same code is not working in Macintosh application.

Do we need to do any specific changes to make it work fine on Macintosh platform as well?

Could you share a demo that could reproduce this issue? Do you use custom-renderer to achieve the calling C# code? You add tag is Xamarin.Forms contains three platforms, Android, UWP and iOS, do not contains Xamarin.Mac.

Unfortunately there is a limit of 1000 characters and it is not letting me paste the source code here. I am using the standard method of customizing the webview.

We have used the method given in the below URL.

They have given method for every platform except the Macintosh. Method given for IOS is not working for Mac.

Demo application for the same is available here :

This sample is for IOS, however this solution is not working for Mac. What changes to be done to this solution to make it work fine on Mac too?

This demo is related to the Xamarin Forms, not Xamarin.Mac, it achieve it by custom-renderer. You can see this thread :https://learn.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/custom-renderer/renderers

Xamarin forms's custom-renderer do not contains Mac platform.

This is mean that I can't call C# from JavaScript in MacOs?
