Checkbox doesn't work as expected

Hi, I have a gallery based on a collection. In this gallery I have 2 checkboxes. The Check Proprety is :

Patch(col2000_vj; LookUp(col2000_vj; ID = gal_2000_vj.Selected.ID); {chkb_ja: true});;

The Uncheck is:

Patch(col2000_vj; LookUp(col2000_vj; ID = gal_2000_vj.Selected.ID); {chkb_ja: false});;

When I click one on the checkbox, the chkb_ja is set to true thats ok, but my checkbox doesn't light up, I have to click again on that checkbox to show up the "checked" symbol. So to uncheck I have to click twice on that box. But I can't find any error.

Somebody has an idea?

Many thanks 🙂

Hi @wuffwuff2004

Make sure the checkbox 'default' property has the following:

ThisItem.chkb_ja

Hope this helps

Hi,

Since your patching your datasource when clicking on the checkbox, the gallery will refresh.

You need to define the Checked property of your checkbox :

Checked = ThisItem.chkb_ja

@wuffwuff2004 That's great glad you're sorted and please mark it as a solution if this solved your issue 👍

Just another quick one on your code - if 'col2000_vj' is feeding the items in 'gal_2000_vj', there is no need to use a lookup in your code. Given that the Checkbox is inside the same gallery, you can use 'ThisItem' context to reference the record:

Patch(col2000_vj; ThisItem; {chkb_ja: true});;

The same will apply to the OnUncheck
