and how are you displaying your table ?

I send you a PDF-file off the screen (the ‘table’ are made with textfields and with HorizontalScroll and VerticalScroll both at the same place and with the first colon standing apart.

I dont know off this is the correct answerd too ‘displaying your table’ ?

Could you please upload the content of the pdf and its image here instead of posting a pdf file that has to be downloaded and opened?

Hello APPI2

I have 2 questions:

First, how do I get the curser to stay on the line I am standing on instead of constantly going up to the top (line 1) ?

(I’ve seen Colin Tree’s ‘Scroll Arrangement Handlers (v2)’ (on ‘Pura Vida Apps’) and tested it, without any visible effect)

Does anyone know if there is an example of this in an AIA with indicative text on how?

See chart example below:

Heading Head 1 Head 2 3 4 5 6 7 8
1 Text Textbox
2 Text Textbox
3
4 Textbox
5
6 Textbox
7
23 Textbox
24 Text Textbox
25
26 Textbox
27
28 Textbox
29
30

Second, how to get the first header line (Horizontal) to stand still when scrolling Vertical (I can only get the first line Vertical to stand still when scrolling Horizontal) and it has to happen at the same time?

(I made the above because one had to both see and write in the same layout, instead of 2 screens;

One to type in and one to see what has been typed).

Best regards

Per Saul

I am sorry for all my input to ‘Report an issue’ but I have to learn how the new ‘Report an issue’ works

You are best off creating an html table

https://puravidaapps.com/table.php

There is a method (scroll down to the end) offered for fixing the top row

Fixing both the top and side is more complicated in javascript (have a good search on stackoverflow to find examples).

You can extend this solution to 8 columns …

Put a heading label over each ListView in a Vertical Arrangement.

130 TinyDBs?

Hello AI2-HELP

I’ve now read and tested the material as I was suggested by the above (several different people)

So now I’ve solved my problem halfway and implemented the solution in my project

For the heading, I have solved it so that one in eight lines is a heading so that (taking into account to the height of the lines, as well as the fact that the first line should stand still when the rest is scrolled) a new heading comes up when the first one disappears out of the image and so on

As for the ‘cursor’ being on the line that is scrolled and not slipping up to the 1st line, so that it must constantly be taken down again, I have found that the ‘cursor’ stays on the line if the finger is not lifted from the line when scrolling (lifting the finger slips the ‘cursor’ immediately up to the 1st line)

I will now try the other different options that You have mentioned and see what works the best for me

So, thank You so much for the help to everyone who has helped me so far

Greetings
Per Saul
