App drop down not populating

[sreejithmp]

Hi folks,

Am trying to get the name column on the drop down from TXT file . But app not working file is reading but not populating the drop down. Could you please help where am gey wrong. Action configured as update value.

connect your input data to your drop-down - not your file browse. Run as workflow. then run as app. see how that looks.

Hi @sreejithmp 

It could be because of the nature of the txt file. It's not considered a Data File itself.

If you save the .txt file as .csv, it should work.

If you cannot change the .txt format to .csv, I recommend using a Chained Analytic App, so you can read the file in the first app, and then have the second app to pick the fields to sort.

Cheers,

I think this is because Alteryx can not work as run time fundamentally.
When we hit run, the data is collected and can not be updated in run time any more.
If I am correct, we have to use a Chained App, which is rather simple actually.

I have prepared a simple sample for your reference.

Got it thank you of the effort. One doubt in this case if there is one change in column in first input will that get reflect in second app dropdown.

Based on my test. the answer is Yes.
That is the exact reason we are using Chaining Apps. 😁
