Default text in combobox

问题

I have 2 comboboxes like on the image and would like to know if it is possible to set some kind of text field for the combobox (so the first box would state Members). This way I would like to get rid of the textboxes above the comboboxes.

I know this can be done by adding the "Members" to the dataset but I donøt want to do that. Is there another way?

回答1:

The effect you are looking for is called a 'watermark', this can be achieved with a value converter as described in the following questions:

Or via a behaviour, as described in the blogpost:
