Label visible based on Combobox

Hello Everyone,

In PowerApps form I have a combobox. In SharePoint list it is a text column. I do have a label 'Please enter a value' on the same screen. I want to show the label text when screen loads and combobox is empty or if user doesn't select any value in combobox. I have tried IsBlank, IsEmpty and CountRows. None of them is working when the screen loads. The label comes hidden when screen loads. However, when you select an item in combobox and deselect it (combobox becomes empty), the label become visible.

I have tried following:

IsBlank(cmbSkills.Selected.'Skills Required')||CountRows(cmbSkills.SelectedItems)=0
 
IsBlank(cmbSkills.Selected.'Skills Required')
 
IsEmpty(cmbSkills.SelectedItems)
 
CountRows(cmbSkills.SelectedItems)=0
 
Please help. I want to show the label text when screen loads or nothing is selected in combobox. 
 
FYI, I am using custom columns and patching the values of columns to SharePoint list.

@MS-19111917-0 Hi,

I think when you assign Lable's Visible = IsEmpty( cmbSkills.SelectedItems ). this works for me.

Or you may consider using InputTextPlaceholder Property of Combox.

You can assign InputTextPlaceholder="Please enter a value"

Hi @MS-19111917-0

Assuming you are putting this in the Visible property, then to me the question isn't why it's not working, the question is why these are giving wrong outputs.

Is this a Multi or Single Select ComboBox as that matters.

What is cmbskills Parent (since its a Form you said) and what are the Items set to ?Do you have a DefaultSelectedItems Set as that will cause the issue (initially) and explain why when you check uncheck it works.

For instance for kicks if you took this code

CountRows(cmbSkills.SelectedItems)=0

And added just a random label in the form and put

Text(CountRow(cmbSkills.SelectedItems))

What does it say?

it will either say -1, 0 or > 0 if its > 0 then DefaultSelectedItems is messing with you. Or you are honestly its a gremlin

What you need to do is prove that your expressions are producing what you expect.

Then resolving why it doesn't make it visible/invisible is easier.

You can even try putting a Reset for the Label in the Onvisible, and well as for the Combobox which should force it to essentially do your click/unclick

@Michael E. Gernaey @stampcoin Thank you for the responses. Digging more into it helped in figuring out the issue. The problem was my label text. I was using If(IsEmpty(cmbItSkills.SelectedItems), "Please enter a value", ""). Replacing it with "Please enter a value" helped and I was able to show and hide label with IsBlank(cmbSkills.Selected.'Skills Required')||CountRows(cmbSkills.SelectedItems)=0

Appreciate your support.
