Dynamic Panel of Buttons WPF C# Common Use

I am trying to find a best or common practice for creating a table of buttons from a database list.

For my use I am creating more of a Point of Sale type screen. Where I want the categories to load as buttons on the entry screen. The buttons would have a simple task of showing a screen of more dynamically created buttons of the actual items. Those buttons would add the items to, lets call it, a ticket.

The solutions I found were few. I am also trying to code this so others can pick it up fairly quickly. I am extremely rusty and only code once in a while. So I try to follow common ways of doing it. I had some ideas but the code becomes hard to read, mostly because of me.

I saw the below link but was not sure if a ListBox was a good container for this. Dynamic filling WrapPanel buttons from DB, setting the event handlers

I am sure a wrappenel is what I would have to use, but do I put it in a container or use it directly. Do I put it in Xaml or code it all, for issues like spacing between buttons? I think I am overthinking it and need to skip for a little bit.

Thank you,

It sounds like you want an ItemsControl, bound to your categories, with a WrapPanel as the ItemsPanel. The Button would go in the ItemTemplate.

<ItemsControl ItemsSource="{Binding CategoriesFromDatabase}"> 

    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <WrapPanel />
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>

    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Button Content="{Binding}" 
                    Command="{Binding RelativeSource={RelativeSource AncestorType=ItemsControl},Path=DataContext.AddToTicketCommand}"
                    CommandParameter="{Binding}" />
        </DataTemplate>
    </ItemsControl.ItemTemplate>

</ItemsControl>

Here I assumed that your view model has properties "CategoriesFromDatabase" (an IEnumerable that you populate from the database), and an ICommand "AddtoTicketCommand" which takes the category as a parameter.
