How to change properties of a single row in a repeating panel?

[alex01]

I am trying to build an app on the side to be used for packing orders.

I have a repeating panel that includes the list of items in the order for a user to pack. Right now I have a button that you can click and will change the row colour to indicate that it has been picked.

def button_pick_click(self, **event_args):
  self.flow_panel_1.background = 'theme:Primary 700'
  self.button_unpick.visible = 1
  self.button_pick.visible = 0

This works fine and here is the design view to get a basic idea.

the screenshot above is a nested repeating row as some items are assemblies so it shows the components, but functionally its the same as the top repeating row.

But now I am looking to extend this to use a barcode scanner. So I want to create a text field that on change will search through the rows in the repeating and if it finds a matching barcode, it will change only that row colour.

I know I can set the properties of a repeating panel using self.repeating_panel.background = 'theme:Primary 700' but this changes all the rwos… so how would I go about changing only the single row if it finds a match?

Any help, or pointers will be greatly apprecaited!

I cant share the app as it is pulling data from our warehouse management software via API.

Here is an example that hopefully will get you started.

The example shows that you can press a button on a parent form and this will raise an event on all children in a repeating panel.

Multiselect on tables

The post above by @jamesralexander is very helpful and I’ve wanted to understand this better myself. Here is a “bare bones” app that demonstrates using raise_event_on_children I hope this is helpful for whoever might need an example. clone: https://anvil.works/build#clone:3NDEAUILXHPGMJ7K=GNRRKY7ETSU2GQEDUT2EEIV6 [com-video-to-gif%20(7)]

Now, of course you will need to extent this example, but in general, from what I can understand, the concept is the same. In your case you would have a text box somewhere, and its change event would raise events on all children panels, changing background color where needed.

I hope this helps point you in the right direction.

I should also mention that you can also loop through repeating panel components with self.repeating_panel_1.get_components(). This would allow you to set up some logic as you iterate through each child.

Thanks @alcampopiano managed to figure it out using that example app you sent using raise_event_on_children()

Great work!

Can you explain how you figured it out. I’m trying to do the same thing
