Text Input (ThisItem.Comments) Inside Gallery Not Updating SharePoint Field (Patch Failing

Posted on by JH-02040138-0

Hi everyone,

I'm working on updating a Comments field in my SharePoint list (Citizens PM List Tracker) from Gallery4 in Power Apps. I've added a Text Input (named txtinputComments) control inside the gallery to display and edit the Comments column (which is named exactly that in SharePoint).

Originally, I set the column in SharePoint as multiline, but have since changed it back to single line to rule out formatting issues. In Power Apps, I also ensured the Text Input is set to single line.

Here's the issue I'm running into:

When I reference Gallery4.Selected.Comments, it works — even though the Text Input is inside the gallery (I am inserting this under Type properties).
But when I use ThisItem.Comments, I get the following error:
“ThisItem currently uses scope, which is not presently supported for evaluation.”

I tried setting:

powerappsCopyEditDefault = ThisItem.Comments
Text = ThisItem.Comments

But neither worked.

For saving the update, I tried the following Patch function on OnChange:

powerappsCopyEditPatch(
    'Citizens PM List Tracker',
    ThisItem,
    {
        Comments: txtComments.Text
    }
)

Unfortunately, that didn’t update the list. I also tried a broader patch using a Save button for OnSelect properties (placed the button outside of my gallery; button named buttonSave):

powerappsCopyEdit//Patch('Citizens PM List Tracker', Defaults('Citizens PM List Tracker'),
//{Status: DropdownStatus, 'Completion Date': CompletionDate, Comments: txtComments, 'Assigned To': cmbAssignedTo})

That also failed, so I tried:

powerappsCopyEditPatch(
    'Citizens PM List Tracker',
    Gallery4.Selected,
    {
        Comments: txtComments.Text
    }
)

Still no luck.

Any ideas what I might be missing? I'm open to suggestions - even if using Update is better than patch! I am still a beginner to this. Thanks in advance for your help.

Text Input (ThisItem.Comments) Inside Gallery Not Updating SharePoint Field (Patch Failing

H i@JH-02040138-0

Confused, I total you this in my previous comment that you needed to use .Value since you were using modern. And in no way should you have to use a Variable

Gallery2.Selected.Comments.Value

From the outside works 100% without the need of a variable. I literally have just reproed it again for you.

You keep talking like Comments is a Property, not a textinput

If the text input is called Comments then of course ThisItem.Comments doesn't work because its the name of the Control

Remove your update in OnChange with the variable

Go to your patch and put

Comments: GalleryXXx.Selected.Comments.Value

And it will work, assuming your Control is called Comments, if its called FOOOOBear then put

GalleryXXx.Selected.FOOOOOBear.Value

don't use variables unnecessarily, it causes bloat to your apps

this label is outside the gallery. Everytime I update a selected value for Comments in the Modern Control, it updates this label to match

Cheers :-)

@Michael E. Gernaey

Understood, thank you for your help! However, I ended up figuring it out yesterday. I am using modern text input placed inside a gallery and upon further research I assigned a variable (varComment) to store the value for later use. For anyone who may stumble upon this post, I resolved the issue using:

For the Value, I entered:

ThisItem.Comments

Under OnChange, I entered:

Set(varComment, txtinputComments.Value)

and for the Save button outside of my Gallery4, I entered:

Patch(

'Citizens PM List Tracker',

Gallery4.Selected,

{ Comments: varComment }

)

(Anyone who reads this, please keep in mind this works because I am using it to only edit one item at a time, hence the use of only one variable varComment).

So let's work on the first issue because we are getting worse and please make sure to always share a whole picture of the entire patch as I dont see a bunch of stuff around the Comments: failure

Is the rest of the expression there.

Also, please, click on the Control and tell me exactly, is it a Classic or Modern Text Input.

@Michael E. Gernaey

When I enter this

Comments: Self.Value OnChange, it's not recognizing the Comments column despite that being what it's called.

And when I enter: into Value, there is an error in the formula

txtinputComments.Value

saying Data type: Text.

Hi @JH-02040138-0

Ok... there are multiple things going on here but this first.

You are using the Modern Input so if you want to grab the text value its

txtInputComments.Value, not txtInputComments.Text

lets start with that

however, since you are in the OnChange of the Control itself you can put

Comments: Self.Value

in place of that txtInputComments.Text

@MS.Ragavendar @ronaldwalcott

Hi, thanks for your replies. I did disconnect the data connection and readded it. Prior to that I did refresh the source. The comments do appear in the section from SharePoint, but the issue is it does not update or save when I make changes in the text input. Below, I replied to Michael E. Gernaey with what I hope is a better explanation that my original comment.

I tested the changes in Power Apps (there's an obvious error lol image on the left side) and when refreshed, it does not display in my SP list like the other columns (SP list screenshot on right):

@Michael E. Gernaey

Hi, sorry about that. Please let me know if this is better.

I added ThisItem.Comments to the text input field I added in my Gallery4 (see below). The error says the formula uses scope, which is not presently supported for evaluation (which is why I tried using the formula Gallery4.Selected.Comments which works, but I beleive is incorrect because this text box is inside my Gallery4, not outside).

I put this Patch formula for the text input box under OnChange which returned the error below (type of argument 'filed_6' does not match the expected type 'Text. Found type error.

Patch(

'Citizens PM List Tracker',

ThisItem,

{

Comments: txtComments.Text

}

)

@JH-02040138-0,

Since you mentioned the change of data type in the schema, Just remove the datasource from the powerapps and try adding it back once.

Sometimes cache issue might be causing this interim problem.

Also describe the problem effectively with the screenshots as per the @Michael E. Gernaey suggestion which helps us.

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item

Hi @JH-02040138-0

Can you please share where you are using

ThisItem.Comments exactly

What is this? powerappsCopyEditDefault

You have so much stuff. Please refrain from adding tons of details like the above. Let's focus on one thing at a time.

You are saying ThisItem.Comments doesn't work

Where are you placing that expressionn

Please share a picture etc. Always share photos.

Also share a photo of it with the Error so we can see what property you are doing it in

Explaining isn't really going to help because we need to see it, and with all the other information it gets clouded.

Saving isn't the issue atm. Its the error on the Expression.
