Posted on by Community Power Pla...

Good day,

I have one checkbox for checks all and checkbox inside in Gallery.

The following problems appeared:

1. On check some of checkbox inside in Gallery it dis the job which I put there, but not marked as checked. I need to click one time more.

2. Let I have 3 records in Gallery. I checked first 2, but when I check the 3rd marking of checking of the first 2 disappeared.

3. I put in Default for checkbox inside Gallery = value of general checkbox. But if I check general then if I want to uncheck some in Gallery it is not possible.

The above problems is only for visual whether the checkbox is checked. Otherwise all job ordered from me is carrying out correctly.

Thanks in advance

I attached one schema

In the Oncheck of the All Checkbox, put this, Set(gblAllCheckbox, true)
In the OnUncheck of the All Checkbox, put this, Set(gblAllCheckbox, false)
In the default of the Checkbox in the gallery, put this, gblAllCheckbox

@Anonymous Not really! When you set it to Allcheckbox.Value it is directly referencing the value. But when you do it through a variable in the OnCheck & OnUncheck. The value gets set only during the OnCheck & OnUncheck of the all checkbox. You will still be able to change the values in the individual checkboxes unless you are doing something else you have not told me of.

Thanks CNT,
Now the problem with All Checkbox and other checkboxes rectified.
Remain the problems inside of checkboxes in Gallery.
I made a video but I can't send here.
Speaking now only for checkboxes inside Gallery. Let we have 3 records - 1,2,3.
I have following:
OnSelect: Patch(summaryCOO,LookUp(summaryCOO, last_name = ThisItem.last_name), {Status: "Approved"});
OnUnSelect: Patch(summaryCOO,LookUp(summaryCOO, last_name = ThisItem.last_name), {Status: "Not Approved"});

Steps:
1/ Click on 1 checkbox - the checkbox is not checked, but field Status changed
2/ Click one more time on 1 checkbox - the checkbox is checked, field Status remain same
3/ Click on 2 checkbox -same as above for 1
4/ Click on 3 checkbox - the checkbox is not checked, but field Status changed , checked marking for 1 and 2 disappeared
It is mean they did not work properly and I can't find it

@Anonymous The Patch for "Approved" must not be in the OnSelect but in the OnCheck of the checkbox inside the Gallery and similarly the Patch for "Not Approved" must be in the OnUncheck.

Sorry for mistake in writhing above. Patch is in OnCheck + OnUnCheck. Patch is working. The problem is of visual showing of checking how I explained above.

@Anonymous Are you doing anything more than the Patch in the OnCheck and OnUncheck?
Do you have any other formulas in the OnSelect or Default properties of the Checkbox.
Do you have any other Formulas in the Items property of the Gallery that could affect this?
