Request: SetGlobalKey in Blazor #45961

Open mrpmorris opened 1 year ago

Is there an existing issue for this?

Is your feature request related to a problem? Please describe the problem.

1: You are writing a datagrid 2: Your data grid renders out a row per object (Person) 3: You use @Key to ensure that if the rows are reordered then the DOM delta is only small. 4: Your user chooses to group rows by DateOfBirth 5: Your data grid now renders out lots of RowGroup components which, in turn, render out the objects within the group (all people born on that day).

RenderTreeBuilder.SetKey only identifies a unique key within the component being rendered, so when we wish to make it look as though screen content has moved elsewhere it causes larger DOM updates. In the case of moving grid rows from a grid into a RowGroup it causes a DOM update of the entire grid.

Describe the solution you'd like

I'd like a .SetGlobalKey / @GlobalKey pair so Blazor can detect when a chunk of the render tree has effectively moved elsewhere.
