Forms Designer Forum

Hello,

I have a parent list called Projects for example. I have a child list called tasks which is linked to the parent list with a unique project ID. I want to calculate the total of all related child tasks and input the project total into the parent list. Example shown below:


Parent List - Projects

Project ID Project Name Project Total

000-001 Project a £15.00


Child List - Tasks

Related Project ID Task name Task total

000-001 Task 1 £10.00

000-001 Task 2 £5.00


Thanks

Hi,

You can calculate the total either in a workflow or with JavaScript directly in a 'Project' form containing a Related Items control with the related tasks. Please, find a sample in the thread:

I am using the following code and Forms Designer 3.0.1.1. The code does not seem to set the var rows, any help?

var total = 0;
var rows = fd.relatedItems(0).data('ctx').ListData.Row;
rows.forEach(function(item) {
alert('Loop');
//total += parseFloat(item.Amendment_x0020_Amount)
});
alert(total)

Hi,

Most likely, Forms Designer 3.0.1.1 does not support fd.relatedItems method. Please, expand the browser console (F12) and check the errors.

Here is the error returned:

Unable to get property 'Row' of undefined or null reference.

The version of the Forms Designer App is 3.0.1.1, I'm using the Forms Designer Client 3.1.4 on the Edit form.

Thanks again!

Hi,
Could you provide a screenshot of your form with the Related Items control?

We have a total of 5 related items and this is the last, var rows = fd.relatedItems(4).data('ctx').ListData.Row;

Hi,
Most likely, you retrieve an incorrect list view. Try to open the form in a browser, expand the browser console (F12), and type in the Console tab:
fd.relatedItems(0).data('ctx').ListTitle

Then change index in the 'relatedItems' to find the correct view.

This form opens in Model and the code fails. On a whim I set the form to open normal and the code works. Can you help?

Are you sure that you put the code into the right form? I've just tested the following scenario in both, dialog and non-dialog modes, and everywhere it worked fine:
1. Inserted the code into the form:
alert(fd.relatedItems(0).data('ctx').ListTitle);
2. Tested in a dialog.
3. Tested in the non-dialog mode.
