EventCallback | Retrofit callbacks on steroids | Android library

I have a strange behavior in Blazor server app.

When I have a list of object and I delete one of the items in the list, it deletes the right item in the list but it copies the data from the last item to the one before it.

It only happen when I bind the list data to my own component. If I bind it directly to an input element it wont happen.

I reproduce the behavior in a small code sample as follow, just try to delete the second item and see the behavior.

Thank for who may help ...

I'm trying to create a generic dropdown component for use across our system. However, I'm encountering issues when binding the EventCallback for when the selected item is changed.

This is my current musings for the generic drop down:

Recently I was reading about variadic templates and based on an example I've seen online I was trying to implement a basic event-system. So far it seems to work fine but I was trying to go a step further and allow N number of arguments to be passed to an event handler function / callback, unfortunately the build error I'm getting is the following and I'm not sure what I'm doing wrong. I looked into similar source codes but still cant figure out what's the issue.

I am learning about EventCallBack with blazor, but i wanted to know

1. Is there a way for my return method to return a second argument on the parent side. I would like to know the rowID that it came from

I'm trying to use OpenTrace and ProcessTrace to read the events of a .etl file.

• the call to OpenTrace successfully returns a TRACEHANDLE
• the call to ProcessTrace returns ERROR_SUCCESS
• but ProcessTrace never calls my EVENT_CALLBACK callback function

I know it's a valid .etl file, because i can open it in:

• Windows Performance Analyzer
• PerfView
• tracerpt

Microsoft provides sample code on reading the events of a .etl file. The basic gist is:

1. Initialize an EVENT_TRACE_LOGFILE structure with the filename we want to open, and the address of our callback function. The callback function is called once for every event in the file:

I have a for loop which iterates over data items to show them and a user should be able to select the items by clicking. What is the best way to achieve that? I want to select the selected PersonItem but deselect the other components. The problem is with deselecting the others.

I'm trying to render dynamic content in Blazor Wasm using DynamicComponent from .Net 6. The component to render is defined in a JSON file with the following structure.

I've got a base class Window in src/Core/Window/:

I have a Search component that implements a debounce timer so it doesn't call ValueChanged (and therefore doesn't update the property tied to it immediately).

The bUnit test doesn't appear to two way bind my value I am updating.
