Patch null in a column

Hi all,

I'm seeing there is/was a bug preventing patching a null value.  It appears this is still the case?  

I'm trying to null out one column on the onchange of another column.  I've tried using UpdateIf and Patch unsuccessfully.  I just want it so that if something is entered into a row on column B, I need it to automatically empty out column A in the same row - either through the onchange of the cell in the gallery, or via the submit button after editing the cell.   Possible?

Thanks

Re: Patch null in a column

You’ll have to use a variable and use it as the value() in the text of estimated control. Then onselect of the actual use a set(). However it probably would just be easier to throw an If(!isEmpty(actual.text),value(estimate.text),value(actual.text)) in your patch for that column you are updating.

Of if it’s two separate database columns then use that same command but put 0 in place of the value(actual.text) spot.

What is the data type? Can’t just set it to blank?

Re: Patch null in a column

They're both values.  Basically I have a column with estimated expenses and another with actual expenses.  If someone finally spends the money, they will update the actual expense text input in the gallery and I want the estimated value to change to 0 or null so it doesnt mess my calculations up (i'm combining estimated and actual together for the "remaining budget" value and don't want a single line item to count against them for the sum of both estimated and actual.

Thx

Thanks that's helpful.  This is what I ended up with in my Patch statement.  

Estimated:If(IsBlank(ActualDataCard.Text),Value(EstimatedExpDatacard.Text),Value("0"))

 

I only want it to empty out the "Estimated" value in the modified line item when that line item's "actual" amount is updated.  So I used IsBlank vs IsEmpty.  I tried just using Value("") instead of Value("0") but Value("") doesn't modify the currently set Estimated value at all.  It'd be cool if I find a way to null the value out so it doesn't show a 0 but it should suffice for my needs.

Re: Patch null in a column

Try reset(control) that should blank it on screen. But not sure if it’ll write null to datasource in patch.
