Getting a single cell out of a record, table or collection

Posted on by Ward_1984

Hey,

Just getting started with Powerapps but searching for a while for the following;

If powerapps start up i see which user has logged in and get his record out a sharepointlist i created.

Collect(ColUserSettings; First(Filter('Users.Instellingen'; User().FullName in Title)))

Now i want to get a single cell out of this record and store it in a var as a string. But whatever i do i don't seems to get the data as a string in the var.

I'm trying to get the column Afdeling in the var but powerapps is always complaining that the var is a record and not a string (text).

How i'm trying it to do is like this:

Set(varUserAfdeling; ColUserSettings.Afdeling)

The point eventually is that i store all the setting from the user for the app in the sharepointlist. So for this example the data will be filtered automaticly on the string we find in the column "Afdeling". I also try'd to use the cell directly in the default tab of the dropdown of the filter options. Like this:

If(ColUserSettings.Afdeling = "Bottelarij"; ColUserSettings.Afdeling)

But get the error that he is expecting a record and not a string.

I hope my question made some sense.

Thanks at advance!

Kind regards,

Ward

HI @Ward_1984

Powerapps recognizes tables, records and fields. All PowerApps controls are set to accept as one of these types. For example, a Textinput or label control can only accept a field. Most of the other controls can accept tables and a form control can only accept a record. In PowerApps a variable can be a table, record or field. Since I don't understand your language, take for example, a dropdown control. It uses a table as its Items property but selects a single record and displays a field value in the window. However. all fields in the record selected are accessible and can be viewed in labels using the following syntax

Dropdown1.Selected.Field1value, Dropdown1.Selected.Field2value where Field1value and Field2value are the names of the fields in the selected record.

To obtain a record to use in a form, you would use Dropdown1.Selected, Gallery1.Selected, or Datatable1.Selected since that defines a single record.

The Filter function takes a table and reduces it to a smaller table. The Lookup function can take a table and reduce it to either a single record or a single field within that record. Consider

Lookup(table,ID=Dropdown1.Selected.ID) will produce a record suitable for a form.

Lookup(table,ID=Dropdown1.Selected.ID, fieldvalue) produces a single field from a table suitable for the Default property of a textbox or the Text property of a label.

I hope that this helps you understand how to retrieve the data you seek.

@Ward_1984 ,

The "ColUserSettings.Afdeling" returns a column of data from a table. Although you only have one row it is still a table. You can easily fix this by using First().

Example:

Set(varUserAfdeling; First(ColUserSettings).Afdeling)

@Jeff_Thorpe @Drrickryp ,
Thanks for the reply!

I don't put the data in a collection anymore like you suggested (@Jeff_Thorpe); but directly in a var with the lookup like @Drrickryp said (it's cleaner so thanks for that 😉
Set(varUser; LookUp('Users.Instellingen';User().FullName in Title))

And now i can indeed use varUser.Afdeling and all the other colums like i wanted in the beginning. So if i understand correctly my problem was that i used a collection and a collection is always a type of table and never a record?

Thanks again.
Ward

you can try
ForAll(
Data,
{
Title: Text(Value.Title),
ID: Text(Value.ID),
Activities: ForAll(Table(Value.Activities),Value.Value)

}
)

Please note that there is a typo: You should use a comma ' , ' instead of a semicolon ' ; ' after the declaration of the variable.
