Csv file to listview

[subrahmanyam_tamarap]

sample.txt (1.7 KB)
i am changing this file extension “sample.csv” to “sample.txt” due to uploading problem
and that font is my mobile font

The file contents look like well formed csv text.

Try the split at \n instead of the csv table block for loading the Elements from the incoming text.

On further thought, the …s look to be an artifact of the ListView deciding early on how much text it wants to display per element, and clipping the rest to keep uniformly sized boxes.

Instead of loading the .Elements from the csv table or the text feed directly, write a procedure to format a summary of each table row for the ListView, and use the SelectionIndex to reference the base global table to access the corresponding selected row number.

@subrahmanyam_tamarap

here 13 rows but it shows only 10 rows how to solve this

Look for a very thin scroll bar at the right of the ListView.

(I like List Pickers better than ListViews for big lists like this.)

It seems that everything is working correctly. list from csv table returns a list of lists. If you plug that block into a listview, it will be converted to a string, showing a part of the nested data. You would have to work out how you want your nested data displayed. Here are some guides for lists

Please solve this problem and please send me blocks

Here is a pre-existing sample of how to format a List Picker's Elements before they are loaded...

Sort of reorganizing lists

Here is my take on the problem, without the restriction on adding attendees to the speaker list if they are already on it. (That is easy to add.) [blocks] [Capture] [Designer] speaker_order.aia (5.8 KB) Selection of an attendee from the Attendees lpk automatically adds him to the end of the speakers list, but he can be removed after selection from the speakers (actually speaker order) list. I added options to rearrange the speaker order.

It's not exactly a custom solution for your address book, but it has the ideas you can apply to build your own solution.

What have you tried ? What works what doesn’t work?

Just giving you blocks will mean you will never learn how to do these things yourself

Have you studied lists and done any tutorials ?

What have you tried ? What works what doesn’t work? Just giving you blocks will mean you will never learn how to do these things yourself Have you studied lists and done any tutorials ?

so what have you tried?

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.
