X-refresh in a basic repeating panel in a data grid

Anvil Q&A

I’ve reviewed the post regarding x-refresh. Unfortunately it’s based on a more complex situation that I have, I think

I’m displaying table data in a very basic repeating panel in a data grid. No form in the panel, etc. As such with limited expertise, I can’t get this to work. Could I get an explanation that is likely applicable for anyone in my position simply executing the basic constructs from the quickstarts?

What’s the desired outcome sorry?

I have a table display in a repeating panel, in a data grid… pretty much out of the box solution. When a users modifies a field in a record (row), I’m changing the sort order. As such, when the operation is complete, I’d like to refresh the repeating panel so that the reordering does not require a browser refresh.

have your tried?

self.repeating_panel.items = self.repeating_panel.items

so the call to a server function to edit status is from a dropdown list on a template form, the call is performed on change. So the underlying repeating panel is not available to that template form.

A simple clone is always useful; however, it sounds like you need to reach back to the template’s parent in order to get access to the items.

You can call get_open_form().some_method_to_deal_with_your_items() from inside your template form. Or use a call to parent, but depending on the structure, that is not always a good idea.

Please see these posts for some context:

Also if the template form’s parent is the repeating panel that you want to refresh

after the templateform has changed you could call…

self.parent.raise_event('x-refresh')

  def intel_status_change(self, **event_args):
    anvil.server.call('edit_intel_status', self.item, self.intel_status.selected_value)
    self.parent.raise_event('x-refresh')

That does not seem to work, here’s a clone

It is helpful for others if you share which form this is on so it saves us from searching around.

I did find the form in question though.

It seems to me like you are trying to set up a custom event.

Please read the “custom events” docs here. I believe there you will see that you are missing some basic set up code so that your refresh event exists (i.e., the event handler) before you call it.

you also need to set and create a function to handle the event.

class home_page(home_pageTemplate):

  def __init__(self, **properties):
    # ...
    self.intels_panel.set_event_handler('x-refresh', self.refresh)
    
  def refresh(self, **event_args):
    #...
    print('refreshing')
