Conditional Require Fields & Reset Gallery

[patrickrw99]

Hi, I have a Power App that I'm building, which has 2 Inputs put inside a gallery, A Dropdown (Option A, B and C) and Text Input Box. All the data in the gallery will be added to a SharePoint List.

I would like to require the user to input the text if the user selects one of the dropdown options (E.g. Opt A). If the user chooses Option A in the Dropdown, but they haven't filled in the text Input, then they will not be able to submit all of the Gallery items. 

I've tried looking for the 'Required' Section in the Text Input Box properties but can't seem to find it. 

Any help is appreciated, thank you!

Hi @patrickrw99 ,

Textinput has no such property.

You should use If condtion before your patct function.

If(Dropdown1.Selected.Value="A"&&!IsBlank( TextInput1.Text),Patch(...))
