MudBlazor MudChipSet - How to set selected MudChip programatically?

I'm using a couple of MudBlazors MudChip in a MudChipSet. The exact amount varies based on a the lenght of a list (creating on MudChip per object in that list).

Now I want to select one of these chips based on saved data. My approach was to create a List of MudChips with one per list item (only setting the "Text" property). I'm then filtering to get the one where "Text" is matching the string I have and set that result to the bind "selectedChip" variable.

However, that doesn't work. Any idea why?

See a demo here: try.mudblazor.com/snippet/wOweEzaxfXjVrtFe

Two things:

1. You should not try to set the item on initialization but rather once the component has rendered. The ChipSet has a chance of being null when OnInitialized is being executed.
2. You are creating a brand new list of chips instead of using the chips that are rendered by your ChipSet foreach loop.

Changes:

    // Run this on first render to pre-set the selected chip
    protected override void OnAfterRender(bool firstRender) 
    {
        if (!firstRender) return; //exit if not first render

        selectedChip = availableChips.Single(e => e.Text == SelectedLocation);

        StateHasChanged();
    }

Add a reference to the chips that are being rendered

    @foreach (var entry in GetWorkLocationHoursMock())
    {
        <MudChip @ref=ChipRef Text="@entry.Location" Color="Color.Primary"/> 
    }

and add those items to your list, instead of creating new MudChip objects

    private MudChip ChipRef { set => availableChips.Add(value); }

The end result should look like this
