SfKanban not working?

I've been trying to get the SfKanban working in an app this morning, but I've had no luck.

Every time I define the columns in XAML I get this error "Android.Content.Res.Resources+NotFoundException: 'String resource ID #0x7f09003e".

I've tried opening the demo provided in the documentation but it also gives me the same error. When I remove the column definitions from the XAML, I dont get the error, but the Kanban doesnt load at all.

Not sure what I'm doing wrong, its probably a simple issue, but I cant figure it out.

Rolled back to SfKanban and it seems to work.

Hi Rhys,


Though we were not able to reproduce the exact issue, we have faced similar issue related to the reported issue. We are providing a workaround to fix this issue, so please add the below highlighted line in the OnCreate override method in the MainActivity.cs file in your Android project and confirm us whether you can able to resolve the reported issue using the below workaround.


Code Snippet:




protected override void OnCreate(Bundle savedInstanceState)



            TabLayoutResource = Resource.Layout.Tabbar;

            ToolbarResource = Resource.Layout.Toolbar;




            Xamarin.Essentials.Platform.Init(this, savedInstanceState);

            global::Xamarin.Forms.Forms.Init(this, savedInstanceState);

            LoadApplication(new App());




We have attached the sample for your reference. Please download it from the following location.

Thank you! 

Adding "Resource.UpdateIdValues();"  fixes the error.
