Take username when a field choice changes

[Kostika]

Hello all, 

This question might have been asked again, but I could't find something. 

In power apps, I have a txt field (1 line of text) and 1 choice column. 

The Default for the choice column is blank/null but the user can change it to "Approved" or "Rejected". 

There might be multiple users with the authority to change the choice column to "Approved" or "Rejected, because of that, I want the name of the user that did the change to be typed/written on the txt field (1 line of text) that I have.

Then, more users will log in and do various changes, but I don't want the Signer's name to be changed again.

1. Unlock the Signer DataCard for editing by selecting it, then on right, click Advanced tab, then click "Unlock to change properties"

2. For the DisplayMode property of the Signer DataCard , use this formula:

DisplayMode.Disabled

 3a. If your form is already in Edit mode and has an Item it is editing, that should be all.

3b. If not, then for the Default property of the Signer DataCard , put something there you want (not sure what that would be for your scenario) - if not sure, skip this step.

See if it helps @Kostika

Hey @poweractivate , thank you for your reply but it's not what I am looking for. 

I want to find a way to take user's name that changed the "Approval" from null to "approved" or "rejected"

Here's to get you going.

On the dropdown's Onchange event add the below

If(
!IsBlank(Dropdown1.SelectedText.Value) && IsBlank(TextInput1.Text),
Set(
UserName,
User().FullName
)
)

In the Default property of the textbox add UserName

Change the Default property of the Signer Data Card.

I am not sure how you know if it should be Approved or Rejected though.

Suppose you want it always Rejected.

Just set the Default property of the Data Card to Rejected then, for example .

I had no idea there was an option "On change" . Thanks for the solution

Oh, you wanted to just auto populate the Signer field with the current user, when they change the drop down.

I did not understand it from your explanation, but if you want that, yes, @VJR solution should work for you in that case.

sorry for my bad explanation.
