Hello.

I Have to update some powerapps code to include a section about sensitive data. The power apps reads from a sharepoint list.

I have created a new column within the a sharepoint list, it is a choice column called SensitiveData, it display choice is Checkboxes (Allow multiple selections)

The values of the choice column are :

PHI
PII
SOX
None of the above

On my Form i have added a data card, with a gallery called Gallery1. Inside that Gallery, i have a checkbox called Checkbox4. This shows all the values of the choice column and allows users to select one or more than once choice.

I have the following code : , but the SensitiveData bit does not update. (as per my comment). The rest works fine.

What am i doing wrong...

Patch(
    'SharePointList',
    LookUp(
        'SharePointList',
        ID = gal_Workspaces.Selected.ID
    ),
    {Update: {Value: "Signed"}},
    {Value: {Value: "Yes"}},
    {Date: Now()},    {SenstiveData: Gallery1.Selected.Checkbox4} //This is the bit that doesnt work. 
);
Set(
    varPopUp,
    false
);
Navigate(
    Confirmation,
    ScreenTransition.Cover
)
 
What am i doing wrong?.  Can someone help me update the sharepoint list to what ever options the users selects from the checkboxes. 4
 
Thanks

Hi @Vstar19,

Firstly, I believe your original post has been solved, so please mark that accordingly. Your next requirement for this rather unusual setup again needs a different approach - this should work in the DisplayMode of the checkbox
If( CountRows(colSelected) > 0 && ( ( CountRows( Filter( colSelected, Value = "Non-Sensitive" ) ) > 0 && ThisItem.Value <> "Non-Sensitive" ) || ( CountRows( Filter( colSelected, Value <> "Non-Sensitive" ) ) > 0 && ThisItem.Value = "Non-Sensitive" ) ), DisplayMode.Disabled, DisplayMode.Edit )

How to updates a sharepoint choice (multiple selections) list column from Power Apps using Patch

Brillant Thank You.

One Final thing.

So i have 4 check box values

1. PHI,

2. PHII,

3. SOX

4. Non-Sensitive

If a user selects Non-Sensitive... How can i disable the other options?, i.e. if they select Non-Sensitive, they should not be able to select PHI, PII or SOX.

Additionally, if they select PHI or PHII or SOX, they should not be able to select Non-Sensitive.

Thanks

Hi @Vstar19,

This depends if you are on an existing or new record. On existing records, the values are designed to remain as you have just updated the record and the Default of the checkbox
ThisItem.Value in LookUp( 'SharePointList', ID = gal_Workspaces.Selected.ID ).SensitiveData.Value

will then read that record and the checkboxes will show the value you just patched. Resetting the check boxes will not alter this (as they will simply read the record values again).

For new records, you have an issue as controls in a gallery cannot be reset from outside the gallery, so
Reset(CheckBox4)

is not going to work (you may also get an error on this). You need to set the Reset property of the check box to a Variable (I have used varReset ) and then toggle the Variable (put this at the end of your patch code)
UpdateContext({varReset: true}); UpdateContext({varReset: false});

@Vstar19,

After the Patch, reset the control that holds the selections

Reset(urcontrolname);

If using checkboxes bound to a collection

Clear(collectionName);

Hi @Vstar19,

This one comes into the category of "should work but does not" - the reason I am guessing being that galleries were never designed to be inside Data Cards inside Forms and although you can manage to insert one with a bit of effort, anything outside the data card simply cannot properly reference the contents of the gallery - the result in my testing was that the filter when run from outside the form returned no records (therefore wrote nothing back).

I have a workaround that seems to work - OnSelect of the CheckBox
ClearCollect( colSelected, Filter( Gallery1.AllItems, Checkbox4.Value ) )

This however is going to cause issues with existing records as the collection will not contain those values initially - so your Patch

With( { _Record: LookUp( 'SharePointList', ID = gal_Workspaces.Selected.ID ) }, Patch( 'SharePointList', _Record, { Update: {Value: "Signed"}, Value: {Value: "Yes"}, Date: Now(), SensitiveData: If( IsEmpty(colSelected), _Record.SensitiveData, ForAll( colSelected As _Data, {Value: _Data.Value} ) ) } ) ); Clear(colSelected)

It would also be a good idea to clear the colleciton whenever you select a new record.

both the above formulaes save without error - but they are not updating the Sharepoint list with the checkboxes i selected. The Sensitive Data column in sharepoint remains blank after i press the button (i have refreshed the sharepoint page)

Hi @Vstar19,

The Patch would be - assuming here that the Items of the Gallery is Choices('SharePointList'.SensitiveData)
{ SenstiveData: ForAll( Filter( Gallery1.AllItems, Checkbox4.Value ) As _Data, {Value: _Data.Value} ) }

Is this for new records only - the values in the Gallery checkboxes for existing records requires a bit more thought here. Assuming you are using classic checkboxes, the Default of the CheckBox should be
ThisItem.Value in LookUp( 'SharePointList', ID = gal_Workspaces.Selected.ID ).SensitiveData.Value

@Vstar19,

Gallery1.Selected.Checkbox4 only returns one selected item (the one associated with the checkbox control), but your SensitiveData SharePoint column expects an array of records in this format:

[{Value: "PHI"}, {Value: "PII"}]

Patch Formula

Patch(
'SharePointList',
LookUp(
'SharePointList',
ID = gal_Workspaces.Selected.ID
),
{
Update: {Value: "Signed"},
Value: {Value: "Yes"},
Date: Now(),
SensitiveData:
ForAll(
Filter(Gallery1.AllItems, Checkbox4.Value),
{Value: ThisRecord.Value}
)
}
);
