Trigger from MatrixDynamic to setValue in the same MatrixDynamic

Hello, we are facing a problem trying to manage a trigger event inside a MatrixDynamic.

What is the current behavior?

Currently, on changing the field in MatrixDynamic, we have a trigger who have the responsavilitie to sett the other fields from the same MatrixDynamic (the same row). The fact is, the trigger works as expected, and capture the runexpression trigger, but the setValue() dosen’t fill target fields.

What is the expected behavior?

The expected behavior should update the other fields from a fieldName dynamicMatrix trigger

// products is the DynamicMatrix name
// This code is executed insed the same dynamicMatrix trigger

surveyModel.setValue('products', [
       {productName:'prod 01'} // thats just  a test, it dosen't update anything
]);

@VGamezz19 I am afraid it is not possible to do it via trigger mechanism right now. If you host SurveyJS Library on your own page, then you can handle survey.onMatrixCellValueChanged event and do what you need. I did not check the code, but it should work

survey.onMatrixCellValueChanged.add(function(sender, options) {
  if(options.question.name != "yourMatrixQuestionName") return;
  if(options.columnName != "yourCopyFromColumnName") return;
  options.getCellQuestion("yourCopyToColumnName").value = options.value;
});

Thank you, Andrew

@andrewtelnov we got it! we manage the dropdown load inside the trigger method of the onMatrixCellValueChanged by isChoiseLoaded

    if (!options.getCellQuestion(options.columnName).isChoicesLoaded) {
      return;
    }

thanks you so much for your time, i’ll close issue
