Thank you for reading my post.

I have a question in a .net Mau iblazor program.

I would like to perform some processing from the right-click context menu, depending on the coordinates or element clicked.

Specifically, I want to control the style of the clicked element with CSS.

With onmousedown etc., you can pass the index to the argument of the event function, but I would like to do the same from the right-click menu.

I am referring to the following.

    Hello,

    After investigation and testing, this feature was not possible for the following reasons:

    • Unable to get the DOM element from the MenuFlyoutItem event when right clicked.
    • CSS style changes to HTML elements cannot be done in MenuFlyoutItem event.

    For this feature, it is recommended that you implement an HTML-based right-click menu in your blazor page and complete styling changes to page elements through onmousedown event and Javascript.

    Please refer to ASP.NET Core Blazor JavaScript interoperability for more details about how to invoke JS in Blazor.

    Best Regards,

    Alec Liu.
