Increment gallery records

Posted on by geraldc1820

The code below works fine and increments rows from a collection connected to a gallery. I want to have it increment up until a title row and then reset to 1 on the first row after the title. The title data will be blank on the rows it needs to increment:

Please modify:

ClearCollect(
    editTable,
    ForAll(
        Sequence(CountRows(editTable)),
        Patch(
            Last(FirstN(editTable, Value)),
            {RowNumber: Value}
        )
    )
);

Create a new variable incrementValue set it to 1 before the ClearCollect

You are still incrementing using Value but setting the increment to the record based on the new incrementValue variable

You reset the incrementValue based on your condition back to 1. Not sure what you meant by after so you may have to move where you do the reset and reset to 0 instead then increment.

The syntax is a bit off I am not typing on my desktop and I don't know exactly the condition you are checking for.

Something like this should work

UpdateContext({incrementValue: 1});

ClearCollect(

editTable,

ForAll(

Sequence(CountRows(editTable)),

If(titlerowvaluecheck,UpdateContext({incrementValue: 1}));

Patch(

Last(FirstN(editTable, Value)),

{RowNumber: incrementValue}

);

UpdateContext({incrementValue: incrementValue + 1});

)

);

Thank you. That concept makes sense but PowerApps will not allow variables set inside a ForALL.

Didn't realise that.

Instead of using a variable we can try using a table with patch.

Set(incrementTable, Table({valueIncrement:1}));

Patch(incrementTable, First(incrementTable), { valueIncrement:First(incrementTable).valueIncrement + 1 })

Replace as appropriate and see if it works. I am assuming that Patch does not execute concurrently and ForAll waits for the completion.
