Hi,
how to format number [with thousand separator] displayed in InfoField of a GroupField?
I tried with this chunk:

	$group = new GridGroup();
	$group->Expand = true; //Collapse
	$group->GroupField = "molecule";
	// $group->HeaderText = "";
	$group->AddInfoField("sVol_16","sum");
	$group->InfoTemplate = "Total 2016: {sVol_16} $";
	$group->ThousandSeperate = "."; 
	$grid->MasterTable->AddGroup($group); 

Use the grid pre render to create it.
// Add this to your row prerender event
$row->DataItem['sVol_16_formatted'] = number_format( $row->DataItem['sVol_16'] , 0 , '.' , ',' ) ;
.....
.....
// use it in your group
$group = new GridGroup();
$group->Expand = true; //Collapse
$group->GroupField = "molecule";
// $group->HeaderText = "";
$group->AddInfoField("sVol_16_formatted","sum");
$group->InfoTemplate = "Total 2016: {sVol_16_formatted} $";
$group->ThousandSeperate = ".";
$grid->MasterTable->AddGroup($group);

	class MyGridEventHandler extends GridEventHandler
	{
		function OnRowPreRender($row,$args)
		{
			$row->DataItem['sVol_16format'] = number_format($row->DataItem['sVol_16'], 0,'.', ',');
		}
	}
	$grid->EventHandler = new MyGridEventHandler();
	$group = new GridGroup();
	$group->Expand = true; //Collapse
	$group->GroupField = "molecule";
	$group->HeaderText = "";
	$group->AddInfoField("sVol_16format","sum");
	$group->InfoTemplate = "Total 2016: {sVol_16format} $";
	// $group->ThousandSeperate = "."; // Display 1'000.53 instead of 1,000.53
	// $group->DecimalNumber = 0;
	$grid->MasterTable->AddGroup($group); 	

Warning: Invalid argument supplied for foreach()
, and if I take "sum" aggregator out from [$group->AddInfoField("sVol_16format","sum");] I get this:

it's the value of first row, not the sum of the groupfield [molecule].
I think that after number_format is applied on [sVol16_format] value, [string $aggregate] value produces this error:
Warning: Invalid argument supplied for foreach()

I had mistakenly thought you were using a grid column.
You are taking a sum and displaying it elsewhere.
That would have worked for displaying row values as formatted numbers.
Seems like a job for KoolPHP. You should submit a ticket to them.
Please let me know what they say. I'm curious on how to handle this issue.

Hi,
I found a pretty nice solution for showing more than one calculated field in InfoField of a GroupField.
Now I have two more problems to solve:
1. trying to align the content of InfoField with the width of a column of the data table
2. number format in InfoField [thousand separator]

$group = new GridGroup();
	$group->Expand = true; //Collapse
	$group->GroupField = "manufacturer";
	$group->HeaderText = "";
	$group->AddInfoField("TotalVol15", "sum"); 
	$group->AddInfoField("TotalVol16", "sum");
	$group->AddInfoField("TotalSales15", "sum");
	$group->AddInfoField("TotalSales16", "sum");
	$group->AddInfoField("TrendVolume");
	$group->AddInfoField("TrendSales");
	$group->AddInfoField("manufacturer");
	$group->AddInfoField("mSh16");
	$group->InfoTemplate = 
	"{manufacturer}, || Vol15: {TotalVol15} $, || Vol16: {TotalVol16} $, || Sal15: {TotalSales15} $, || Sal16: {TotalSales16} $,  || TVol: {TrendVolume}, || TSal: {TrendSales} $, || mShare: {mSh16} %";
	$group->ThousandSeperate = "."; // Display 1'000.53 instead of 1,000.53
	$group->DecimalNumber = 0;
	$grid->MasterTable->AddGroup($group);

Γεια σου, μετά από μια κουραστική μέρα ήθελα κάτι να με χαλαρώσει και διάβασα για μπόνους για παίκτες από την Ελλάδα σε ένα φόρουμ. Στη μέση του ποστ εμφανίστηκε το https://spinmama.com.gr/bonus και αποφάσισα να δοκιμάσω. Ξεκίνησα με Wolf Gold και έχασα μερικούς γύρους στην αρχή. Ρίσκαρα λίγο παραπάνω και τελικά κέρδισα μια όμορφη νίκη που άλλαξε την διάθεσή μου. Το συνιστώ για μια σύντομη και διασκεδαστική εμπειρία.
