Possible to use checkboxes instead of combobox for multi-valued choice fields?

[colonel_claypoo]

I've worked through @CarlosFigueira's examlpes to circumvent the issue of not having had support for multi-valued choice fields here and here. Thanks for those Carlos!

In one of those guides checkboxes were employed but had to be used in conjunction with a single line text field.

Is it by this time possible to use multi-valued choice fields with checkboxes instead of a single line text field?

With the checkbox approach the Default property of a checkbox had to be set to "Choice1" in Split(Parent.Default; ",").

So I was thinking that for using the multi-valued field I could use something like "Choice1" in Split(Choices(ListName.MultivaluedChoiceField); ",") but unfortunately, this does not work.

The error message is Invalid argument type (table). Expected a Record value instead.

Any idea if it's possible to use SharePoint list multi-valued choice fields with checkboxes in PowerApps?

Thanks a lot.

Hello,

is it okay to bump my own thread? I'm still looking for a solution. What can I do about the error message Invalid argument type (table). Expected a Record value instead? Would it be an option to kind of collect all the values of ListName.MultivaluedCoiceField first and combine them in a record?

Thanks.

Yes, you can now use checkboxes directly in a multi-valued choice field. For the default value of each checkbox, you'd use this expression:

"Choice 1" in ThisItem.ChoiceMultiple.Value

Where 'Choice 1' the value of the choice column associated with the checkbox, and 'ChoiceMultiple' is the name of the choice column from SharePoint. You don't need to use the Choices function here, as it would return all possible choices, and you want only the values that are saved in the list.

For the Update expression, you can use something similar - you need to have an expression whose result is a table with a 'Value' column (see this post for more details), and you can use an expression like this one to accomplish that:

RenameColumns(
    Split(
        Mid(
            Concatenate(
                If(chkChoice1.Value, "," & chkChoice1.Text, ""),
                If(chkChoice2.Value, "," & chkChoice2.Text, ""),
                If(chkChoice3.Value, "," & chkChoice3.Text, ""),
                If(chkChoice4.Value, "," & chkChoice4.Text, ""),
                If(chkChoice5.Value, "," & chkChoice5.Text, "")),
            2),
        ","),
    "Result",
    "Value")

In my example I have 5 possible values (thus 5 checkboxes), but you can configure it for your scenario.

Thank you very much for your reply Carlos. I've not had the chance to test this out yet but I'm sure this will be helpful to anyone.
