TreeGrid selectionAppearance header

[yavery]

Hi,

When defining TreeGrid components with selectionAppearance : 'checkbox', we used to have (7.0rc2)
a checkbox at the TreeGrid header level which allowed users to clear/set all items at once. With the
upgrade to 8.0 nightly builds, we lost the checkbox in the header portion.

Following is the code to reproduce :

var treeGrid = TreeGrid.create
({
	dataSource : this.treeDataSource,
	isFolderProperty : 'isFolder',
	selectionProperty : 'isSelected',
	nodeIcon : MeiReportNavigator.dimIcons.find('name', dimName).icon,
	folderIcon : MeiReportNavigator.dimIcons.find('name', dimName).icon,
	selectionAppearance : 'checkbox',
	leaveScrollbarGap : false,
	layoutMargin : 0,
	width : '100%',
	height : '100%',
	layoutMargin : 0,
	membersMargin : 0,
	visibility : 'hidden',
	data : data,
	fields : [ { name : 'caption', treeField : true } ]
});

if (isSingleSelect)
	treeGrid.setSelectionType('single');

Any idea how to have that checkbox in the header portion appear again ?

Thanks,

Anyone could confirm this ? Could it be a regression in 8.0 ?

Thanks,

Not really a regression but rather change of functionality. The checkbox is no longer a separate column but integrated into the nodes. To get similar usability, show a root node and enable cascading selection.

Thanks,

All I wanted to confirm is that it wasn't a regression.

From a usability standpoint, it wasn't obvious anyways for users that they
could click in the header to select/clear all.

We'll most probably add two buttons below the treeGrid to that effect instead,
or a node contextual menu (select/clear all children).

Kind regards,
