CheckAll/Reset CheckBox inside component

Hi All,

I'm trying to build a component that has a gallery with a checkbox control. Outside of the gallery, I have another checkbox control named AllChkbox and the default value is "true". I set Default property of the checkboxes in the gallery to be AllChkbox.Value. It's all good on visible event of the screen like below:

When I untick any one of the checkboxes inside the gallery, I'd like the AllChkbox control outside the gallery to become unchecked. However, if I check the AllChkbox control, I would also like to check all the checkboxes inside the gallery. I've been running circles with this logic and can't find the solution. I found one solution here, but this is not inside a component. Is it possible to create this logic inside a component? Help! 😔

Hi @Bochie ,

I did a test for you.

CheckBox1:

Default: B

OnCheck: Set(A,true);Reset(Checkbox1_1);Reset(Checkbox1_2);Reset(Checkbox1_3)

OnUncheck: Set(A,false);Reset(Checkbox1_1);Reset(Checkbox1_2);Reset(Checkbox1_3)

Checkbox1_1:

Default: A

OnUncheck: Set(B,false);Reset(Checkbox1)

Checkbox1_2:

Default: A

OnUncheck: Set(B,false);Reset(Checkbox1)

Checkbox1_3:

Default: A

OnUncheck: Set(B,false);Reset(Checkbox1)

Best Regards,

Wearsky

Thank you for your reply @v-xiaochen-msft ! I solved it last week by adding a boolean column "Show" to the collection and applying the same principle you outlined above. I had to add the columns because the number of checkboxes are dynamic and they are inside a gallery. In your sample above, the sub-checkboxes are not inside a gallery.
