TreeGrid node collapse loses selections

[yavery]

Hi,

Whenever a TreeGrid gets one of its nodes collapsed, any selections on nodes located below
the node being collapsed, are lost (cleared).

Is there any way to preserve selections, even when a node gets collapsed.

Using the feature explorer, you can see the behavior we are describing using the following
slightly modified code:

http://www.smartclient.com/index.jsp#nodeTitles

isc.TreeGrid.create({
    ID: "employeeTree",
    width: 500,
    height: 400,
    dataSource: "employees",
    autoFetchData:true,
    nodeIcon:"icons/16/person.png",
    folderIcon:"icons/16/person.png",
    showOpenIcons:false,
    showDropIcons:false,
    closedIconSuffix:"",
    selectionType : "single",
    selectionAppearance : "checkbox",
    fields: [
        {name: "Name", treeField: true, formatCellValue: "record.Job+': '+value"}
    ]
});

Thanking you in advance for your help.

What version of SC are you using? Can you try a new nightly?

We're still using 7.0 RC2. We haven't moved to v8 yet.

[davidj6]

This appears to be fixed in the latest versions.

Yes, this was changed in 8.0 so that selection persists across expand/collapse. If you need this behavior in 7.0, unfortunately it's going to mean tracking the selection yourself via implementing mousedown/mouseup event handlers and using overrides of getCellStyle et al to provide styling for your own notion of selection - a fair bit of work.

[yavery]

No that's fine. We'll migrate to v8.0 at some point in time.

Thanks for confirming.
