Reset Checkboxes in Gallery

[ericonline]

Hello, 

Scenario: 

• Gallery embedded (hacked!) into a Form
  • Extended one card height
  • Insert/Gallery
  • Changed Data Source for Gallery
• Checkbox on each Gallery item
• The boxes which are checked are collected and used to show/hide labels and input boxes lower down the form

Issue: 

• When Cancel button is clicked on Form, the checkboxes inside the Gallery remain checked
  • ResetForm(<form_name>);Clear(<checkbox_collection>);Back()

Question: 

• How do I clear the checkboxes in the Gallery so that the User is presented with a clean slate upon opening the app each time? 

Thank you very much!

Hi @ericonline

You can use

Reset(Checkbox_Name);

This will reset your checkbox to the default. Put it next to ResetForm() so it happens at the same time.

Hi MartynasJurkus, 

Thank you for responding. 

Unfortunately, this did not work: 

• ResetForm(<form_name>);Reset(<checkbox_name>);Clear(<checkbox_collection>);Back()

Just to reiterate, this is a Checkbox within a Gallery. Reading the Reset docs it does say "You cannot reset controls that are within a Gallery or Edit form control from outside those controls....". I'm looking for another method.

Hi @ericonline

There is another way using context variables.

In the Checkbox.Reset add a context variable.

Example:

Now next to your ResetForm();

Add this code:

UpdateContext({ResetCheckbox:true});
UpdateContext({ResetCheckbox:false})

This will clear all checkboxes in Gallery when the form Resets.

Thanks a million.  I also had the checkbox inside the Gallery and I had an X button icon that I put there in case the user decided not to attach any file he/she just X-out and the checkboxes should have been cleared out and that what you advice did.  I tried your advice before but I just typed this formula: UpdateContext({ResetCheckbox:true}).  The second type I read your blog I type UpdateContext({ResetCheckbox:true});
UpdateContext({ResetCheckbox:false})

and it worked... Thanks!

UpdateContext({ResetCheckbox:false})

and it worked... Thanks!

Thanks it worked but why two times we've update the context?

UpdateContext({ResetDateControl:true});

UpdateContext({ResetDateControl:false});
