Validation on dropdown and textbox

[nagestiada]

So I have multiple dropdown and text input with an validation label on each. 

Here is a sample code of visible on validation label.

TextBox: If(DataCardValue17.Text="",true,false)

Dropdown: If(IsBlank(DataCardValue21.Selected.Value),true,false)

What I want to do is for all my validation label to appear once I click on the button submit.

@nagestiada , 

Try either making the Default of the Text boxes "" (empty string) or use this code.

If(
   IsBlank(DataCardValue17.Text) || 
   IsBlank(DataCardValue16.Selected.Value) || 
   IsBlank(DataCardValue21.Selected.Value) || 
   (   DataCardValue16.Selected.Value="Other" && 
       IsBlank(DataCardValue18.Text)
   )|| 
   (
      DataCardValue21.Selected.Value="Yes" && 
      IsBlank(DataCardValue6.Text) && 
      IsBlank(DataCardValue7.Text)
   ),
   UpdateContext({vViewLabel:true}),
   UpdateContext({Popup:true})
)

Also put a table on the screen with vViewLabel and see if it turns to true when it should.

If(
   IsBlank(DataCardValue17.Text) || 
   IsBlank(DataCardValue16.Selected.Value) || 
   IsBlank(DataCardValue21.Selected.Value) || 
   (   DataCardValue16.Selected.Value="Other" && 
       IsBlank(DataCardValue18.Text)
   )|| 
   (
      DataCardValue21.Selected.Value="Yes" && 
      IsBlank(DataCardValue6.Text) && 
      IsBlank(DataCardValue7.Text)
   ),
   UpdateContext({vViewLabel:true}),
   UpdateContext({Popup:true})
)

this works but when I clicked yes 

DataCardValue21.Selected.Value="Yes" && IsBlank(DataCardValue6.Text) && IsBlank(DataCardValue7.Text)

 the and on 6 and 7 does not work, one blank and one not blank still goes through submit.

Hi @nagestiada ,

This is not a coding issue, but an exercise on logic and and/or brackets - I do not know what you are trying achieve.

Can you please put in plain words the If / and /or you are trying to get?
