Posted on by cchan000 359
Hi. I am extremely new to PowerApps but trying and eager to learn.
I have a SP list I am editing in Powerapps.
I have a dropdown that has two available choices, Black or White.
When someone chooses Black, I want another data card text box to appear.
In Tree View, when i go into the Black/White choice datacard, i see DataCardValue5 in it.
In the tutorial I learned to changed the visibility of the text box I want to change visibility by using a formula like this:
 
If(DataCardValue2.Value = true, true)
 
so I Tried this:
If(DataCardValue5.Value = Black, true)
 
this didn’t work. What am i doing wrong? I read that I have to find out the dropdown name? I thought it was DataCardValue5.
 
Any help please would be tremendously appreciated.

    The value you are setting in your dropdown is a string.  You have to test it as a string .  Use the following code instead.

    If(DataCardValue5.Value = "Black", true,false)

    Hi! Unfortunately it doesn't work.

     

    It says Name isn't valid. This identifier isn't recognized.

     

    I used black/white as an example, but the drop down selection is actually Linear/NonLinear (which is in the screenshot).

     

    Please see attached screenshot.

    Hi @cchan000 ,

    DataCardValue5.Value can not be used to represent the drop down's selected item.

    I suggest you try this

    If(DataCardValue5.Selected.Value="Linear",true,false)

    what if i want it to be visible if a user selects Black or White from the dropdown.

     

    the below did not work.

     

    If(DataCardValue5.Selected.Value="Black" or "White",true,false)
