Yes/No column - SPO

Hi

I have a Yes/No column in SPO, by default in SPO, I cannot change it to be a null value.

 

Is there a way in Power Apps i can make the default selection to be nothing?

 

tried {} in defaults but it needs a boolean value

Hi @Lefty ,

1)No, I mean you could display blank value in sharepoint list.

But in powerapps, the blank value of yes/no column will display as false, not blank.

This is the field that I use Blank() to update.

 2)Sorry, I forgot to add {} between ColumnName:Blank(), you need to use 

{ColumnName:Blank()} in patch function.

3)Please replace column name with your yes/no column name, not use column name directly.

 

UpdateContext(
{
VarPatchedRecord:
Patch(
ListName, Defaults(ListName),  //replace with your listname
Form1_1.Updates,
Form1_7.Updates,
Form1_2.Updates,            //replace with your form names
{ColumnName:Blank()}    //replace with your yes/no column name
)
}
);

 

The formula that I posted is just an example, you need to replace with all your data.

The formula that I used:

 

UpdateContext(
{
VarPatchedRecord:
Patch(
list2, Defaults(list2), 
Form1.Updates,          
{yestest:Blank()}    
)
}
)

 

//list2 is my list name, Form1 is my form name, yestest is my yes/no field name

Kindly give further explanation. Is the default in a dropdown?

The SPO field type is a Yes/No type field, I know if it was a was dropdown  (choice type) I think i could have used {} to make it blank.

Thats my column in SPO, and by default it always selects Yes/No, it cant be blank, i was hoping in PowerApps i can set it to an empty field, as this column does not get completed until later in the form, at stage 3 

Hi @Lefty ,

Do you want to update a yes/no field with blank value?

Two steps:

1) set this field not required

3243.PNG

 2)turn on this setting:

 3)the formula:

Patch(list2,Last(list2),{yestest:Blank()})

//list2 is my list name, yestest is my yes/no column.

You just need to use Blank() to update.

Then you could update this field to blank.

Hi @v-yutliu-msft 

Thanks for your response

I've tried your suggestion, by turning on the feature and then on my first submit screen, before i do an updatecontext, i have placed this:

 

Patch(ListName, Last(ListName),{ColumnName:Blank()});
UpdateContext(
{
VarPatchedRecord:
Patch(
ListName, Defaults(ListName),
Form1_1.Updates,
Form1_7.Updates,
Form1_2.Updates
)
}
);

 

But it still updates a column I do not have on this form, to 'no', I have around 8 columns which need to be kept to blank at this stage of the form, but having tested on just 1 column, the above did not work for me

Hi @Lefty ,

Last(ListName) just represent a record that you want to update (as an example in my test.)

Could you tell me whether do you want to create a new record with blank yes/no value or edit an existing record with blank yes/no value?

1)create a new record

Try this formula:

UpdateContext(
{
VarPatchedRecord:
Patch(
ListName, Defaults(ListName),
Form1_1.Updates,
Form1_7.Updates,
Form1_2.Updates,
ColumnName:Blank()
)
}
);

2)edit an existing record:

UpdateContext(
{
VarPatchedRecord:
Patch(
ListName, the record that you want to update,
Form1_1.Updates,
Form1_7.Updates,
Form1_2.Updates,
ColumnName:Blank()
)
}
);

 

But to make this formula work, you need to 

1)set this yes/no column not required

3252.PNG

 

2)turn the setting that I mentioned on

 

Please notice that:
1)You could only update this field to blank value.

It's not supported to change the field's default value to blank. In sharepoint list, this column type will always have a default value, yes/no, blank is not included.

2)If you display yes/no column value in powerapps, the blank value will display as false.

you could use IsBlank(ThisItem.yesnocolumn) to justify.

Hi @v-yutliu-msft 

Little confused here. Are you saying even if I put this in the code:

ColumnName:Blank()

It will still show up as Yes/No in my SPO list? as that is the problem. I do not want the value to show up in the SPO list, rather I want it to show up with nothing (null value) in the SPO list.

 

Also yes I am creating a new record, but tried the formula and a few variations, but they wont work. If i put the column name (internal SPO column name)

I get a red line, and the error states "Name isnt valid. This identifier isnt recognized"
If i use the the datacardname, i get "cannot use a non-record value in this context"

 

The SPO column settings are set to not be required field types

 

Hi @Lefty ,

1)No, I mean you could display blank value in sharepoint list.

But in powerapps, the blank value of yes/no column will display as false, not blank.

This is the field that I use Blank() to update.

 2)Sorry, I forgot to add {} between ColumnName:Blank(), you need to use 

{ColumnName:Blank()} in patch function.

3)Please replace column name with your yes/no column name, not use column name directly.

 

UpdateContext(
{
VarPatchedRecord:
Patch(
ListName, Defaults(ListName),  //replace with your listname
Form1_1.Updates,
Form1_7.Updates,
Form1_2.Updates,            //replace with your form names
{ColumnName:Blank()}    //replace with your yes/no column name
)
}
);

 

The formula that I posted is just an example, you need to replace with all your data.

The formula that I used:

 

UpdateContext(
{
VarPatchedRecord:
Patch(
list2, Defaults(list2), 
Form1.Updates,          
{yestest:Blank()}    
)
}
)

 

//list2 is my list name, Form1 is my form name, yestest is my yes/no field name
