Move rows within a table using buttons

[RogerD441]

Hello Guys,

I am trying to create a dynamic table and I have been trying to figure out how best to do it. Here are my requirements

1) The table will have 12 rows, the number of rows will not change.

2) The table will have 2 columns.

3) The point of the table is for the user to reorder based on priority.

4) The data must persist when saved (this one i know how to do).

I have been creating a subform around a row and adding a up and down arrow buttons to each one. I was going to use a moveinstance command but I don't quite understand how the indexing will work.

If you guys have a better suggestion or an example, i would really appreciate it.

Thanks,

roger.

Hi,

Repeatable objects have a zero-based numbering system. So Row1 with 12 instances, would look like Row1[0], Row1[1], ... Row1[11].

So the following Javascript would move the row up:

if (Row1.index != 0) 
{     
     var nIndexFrom = Row1.index;
     var nIndexTo = Row1.index - 1;     
     _Row1.moveInstance(nIndexFrom, nIndexTo);     
}     
else 
{     
     xfa.host.beep("3"); 
}

A similar script would move the row downwards. Note I have used Row1.index, you could also use this.parent.index if the button is in the row. If it is buried in subforms, you may need this.parent.parent.index, to get to the instance of the repeating object.

Hope that helps,

Niall

The problem with it being repeatable is that the text in the rows of column one are all different. will that change it?

Hi,

I have updated a sample to include moving rows: https://acrobat.com/#d=khu3Ik*9LUz60afNWuCUsA

Note that in this table there are TWO repeating rows. The first reacts to the dropdown, the second to the add row button.

So you can move rows within their respective instances. The hover colour is set to blue for Row1 and green for Row2.

In the first example I have used the Row1 name to access the current index. Whereas for hte second example I have used this.parent.parent.index. This is just to show the different approaches.

Note how I have set up this form to give visual and audio feedback to the user when they can't move a row, rather than an app.alert.

Hope that helps,

Niall
