Remove item based on ID

Posted on by Community Power Pla...

Hi All,

I've recently been updating my app so I am using ID's and lookup tables, which means that if a name changes, it flows through to everything in the app. So I have a remove function, and now that the table I'm removing from has an ID instead of the name I select in the listbox to remove, I'm having trouble to get the code to work.

Basically I select an item in a list box, click a button, and the item is removed from a table. However the item I select is the name of the item, and the item in the table to remove is the ID of that name. Being that there could be multiple selections, I have used a collection.

ClearCollect(ItemCollect, {item: ListBox4.SelectedItemsText.Value});

ForAll(ItemCollect,
RemoveIf(Mapping, LookUp(Items, crb20_item = item, crb20_item_id)));

I'll get my head around the lookups soon I hope!

Thanks

I have chosen to replace your LOOKUP function with a comparison statement instead. It removes allmatching records from Mapping where crb20_item is equal to item in the ItemCollect collection. Is this what you to wanted to achieve?
ClearCollect( ItemCollect, {item: ListBox4.SelectedItemsText.Value} ); ForAll( ItemCollect, RemoveIf( Mapping, crb20_item = item[@ItemCollect] ) );

I need to use the lookup, because the item in the listbox is a name, and what is in the mapping table is an ID, so need to match the name in the lookup, with the ID in the mapping table, and remove the matching record.

This i'm closer with this, but getting invalid argument type:

ClearCollect(ItemCollect, {item: ListBox4.SelectedItemsText.Value});
ForAll(ItemCollect,
RemoveIf(Mapping, crb20_item = LookUp(Items, crb20_item_id = item, crb20_item_id )));

Where in your formula are you getting an invalid argument error?

Also, I'm gonna give this another shot revising my previous formula which was not making any sense...

ClearCollect( ItemCollect, ListBox4.SelectedItemsText ); ForAll( ItemCollect, RemoveIf( Mapping, crb20_item = ItemCollect[@Value] ) );

This bit gives the invalid argument error:

learCollect(ItemCollect, {item: ListBox4.SelectedItemsText.Value});
ForAll(ItemCollect,
RemoveIf(Mapping,
crb20_item = LookUp(Items, crb20_item = ItemCollect.item, crb20_item_id
)));

In your example, when you have:
RemoveIf( Mapping, crb20_item = ItemCollect[@Value] )
crb20_item in the mapping table is an ID. The selection from the listbox is a name, so I'm not sure how that can work 😕

Got it 🙂

Clear(ItemCollect);
ForAll(ListBox4.SelectedItems,
Collect(ItemCollect, {
item: ListBox4.Selected.crb20_item
}));
ForAll(ItemCollect,
RemoveIf(Mapping, crb20_item =
LookUp(Items, crb20_item = item, crb20_item_id)));
