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 disabled
• When a value is selected, the button will go into Edit mode

Hello @johnjohn123,

I have created a Drop Down with Item as ["","1","2"]

in Display Mode of button

If(IsBlank(dropDownValue.Selected.Value),DisplayMode.Disabled,DisplayMode.Edit)

Check if the Drop Down Value is null, if null Disabled else Edit

Hi @johnjohn123 ,

Use this on button property 'DisplayMode' insert this formula

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

Hope this helps.

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
