Hi @johnjohn123 ,


I tried to recreate your use-case and here is a solution that seems to work based on what you have mentioned -

  1. Insert a combobox instead of a dropdown (Combobox1, in my example. If you want to have only a single value selected from a user, you can turn "Allow multiple selection" off
  2. The Button's DisplayMode can be set to this -


If(ComboBox1.Selected.Value = Blank(),Disabled,Edit)


  • When there is no value selected, the button will be disabledsivaecl_0-1631856074573.png


  • When a value is selected, the button will go into Edit modesivaecl_1-1631856117969.png

Hi @johnjohn123 ,


Use this on button property 'DisplayMode' insert this formula

If(CountRows(ComboBox.SelectedItems) = 0, DisplayMode.Disabled, DisplayMode.Edit)


Hope this helps.

@Ethan_Ri am using dropdpwn not combobox..

Hi @johnjohn123 ,

No problem,

Use this then,

If(IsBlank(Dropdown1.Selected), DisplayMode.Disabled, DisplayMode.Edit)


For this, you will require 'AllowEmptySelection' property of Dropdown set as true


Hope this helps
