Add immovable "Edit" button to ComboBox in WinUI 3

youki 1,016

Is it possible to add a immovable button (item) to the ComboBox, maybe by custom XAML in the App.xaml like in the image?

(As you can see, the button is immovable below the scrollable part of the ComboBox.)

User's image

What do you mean "the button is immovable below the scrollable part of the ComboBox"? Could you please provide a sample to help us reproduce the issue?

This is an example image from the internet. Is it possible to implement a button below the scrollable part like in the image?

As far as I'm concerned, you couldn't by custom the style of the combobox to create a combobox like this layout. If you want to realize it, you need to use the UserControl to create a custom combobox.

Is it feasible as a UserControl, i.e. is the concept of building something like this reasonable?

Unfortunately I don't know the concept, but it certainly won't be as simple as an ASP.net UserControl, right? (Surely it's equivalent to a WinForm customized control? That's hell).

As far as I'm concerned, you need to create a custom control.

Ok,

thanks. By the way, as I saw, it‘s called a dropdown/ combo box footer.
