Canvas App Combobox fill color change

Posted on by KhurramJamshed

Hello,

I have a combobox sitting nicely as gallery column filter dropdown.

My challenge is to change a background color of a combobox when the dropdown values get visible.

In below screen shot i had to change the fill color of combobox to same as fill color of label on which its stacked up, so that it look as part of a column header

but when i click on a chevron and the dropdown value becomes visible, the background fill color of a dropdown values is green as one can expect.

how can i change it to neutral/white when the dropdown values are visible? and then back to green when its not visible?

any ideas will be appriciated.

Thanks.

You can change the fill color to:
RGBA(255, 255, 255, 1) or White

i wish it could be that simple 🙂
the issue is not that i dont know how to change a color.

I have to change a color (to say grey) when the dropdown values are visible, and then change it to (say green to match the column background color) when it's collapsed.

thanks for your reply.
in the first screen shot, where you can see a chevron (next to Program) is actually a combobox without border and background fill as Green so that it look as part of a column:

In the second screen shot, when i click on a combobox and the values get displayed is when the background is still green (as expected). but this is when i actually want to set background fill to (Gray or white or etc).

so basically a fill color to be changed when combbox is expanded, and then change it back when its colloapsed.

Hi @KhurramJamshed ,

There is no out-of-box property to check if the combo box is being expanded.

As an alternative workaround, you can try to create a custom Combo box by Textinput box, Gallery and a Down icon.

I have attached the sample app below, please let me know if it works for your case.

Custom Combo Box....
