file7.csv

What I need to do is to read data from a csv like the one I have updated and then fill an edit field in app designer with what is written in that csv file.

As example i updated one with just a simple text in it.

I have tried with something like

DataComments = readtable('file7.csv');

app.CommentsEditField.value = DataComments

but it doesn't work.

在 MATLAB Online 中打开

file7.csv

For this specific example, readlines might work better than readtable.

DataComments = readlines('file7.csv')
DataComments = 3×1 string array
    "Comments"
    "testo di prova"
    ""

Then pick which one of these three strings you want to use to fill in your EditField. For example:

app.CommentsEditField.value = DataComments(2);
disp(app.CommentsEditField.value)
testo di prova

Ok, thank you. I have tried to make it work with a drop down menu, but it doesn't work. It goes in conflict with item data of drop down menu.

If you want help with that issue, you are going to need to provide your app designer code and any data needed to run it (or a stripped down version of it that illustrates the issue).
