Multiple Galleries

Question

I would like to give my app user multiple galleries from which they can choose a background for a screen,
how  can I achieve this?

Hi Joel,
There are two ways you could look at this, either:
1) You could leverage the same technique that we suggested
here for a similar question you asked. The question was about shapes, but the same learnings will apply to the
'Fill' of the Canvas Screen.
OR
2) If you have to leverage galleries, then you could do the following:
- Drop a Custom Gallery, called Gallery1
- Set its 'Data' property to the list of colours you intend to expose i.e ["Red", "Blue", "Green"]
- Then Add a Label visual to Gallery1, called Label1. You will have to re-adjust the size of the label so it fits nicely into
Gallery1
- Set Label1's 'Fill' property to ColorValue(ThisItem!Value). Now you should notice that each item in
Gallery1 has a different colour
- Proceed to set the 'Fill' property of the Canvas Screen to
ColorValue(Gallery1!Selected!Label1!Text)
Now when you select an item with Gallery1, the Canvas Screen should also change to match that colour.
Hope this helps.
