How to create a 'Searchable / Filter' Combobox in DataGrid WinUI 3

Question

As far as the official docs go, it is all hopeless. I have checked all across web, asked chatGpt but no help. I need something like this, for each cell in DataGrid of WinUI 3.

I have tried using DatagridComboboxColumn, but it is NOT searchable. I tried to use '<combobox>' it KINDOF works as its editable but I am not able to Fill the Combobox Items and Bind with Parent DataGrid.

You can use the built-in AutoSuggestBox for this.

If you want the suggestions inside the control itself, I guess you could try the AutoCompleteTextBox (GitHub/NuGet/YouTube).

<toolkit:AutoCompleteTextBox
    IsSuggestionCaseSensitive="false"
    SuggestionForeground="HotPink"
    SuggestionPrefix="..."
    SuggestionSuffix=" ? [Press Right]"
    SuggestionsSource="{x:Bind Suggestions, Mode=OneWay}" />
