In TreeGrid child nodes are not getting checked/unchecked on parent check/uncheck

[vikas.m.yadav]

In TreeGrid, i'm using 1st column as a checked tree nodes.
On parent checked node click, it doesn't check/uncheck its child node.

Please help to fix this.

Thanks in advance,
Vikas

It is not documented as doing so. If you want hierarchical selection you need to implement it via CellClick and similar events - it's not built-in yet.

I'm trying to implement this through 'FolderClickEvent' but did not get any method to select/unselect nodes.

import com.smartgwt.client.widgets.tree.*;
import com.smartgwt.client.types.*;
import com.smartgwt.client.widgets.tree.events.*;

import com.starent.ipms.client.common.main.*;

public class STreeGrid extends TreeGrid implements FolderClickHandler
{
	public STreeGrid()
	{
		super();
		setSelectionAppearance(SelectionAppearance.CHECKBOX);
		addFolderClickHandler(this);
	}

	public void onFolderClick(FolderClickEvent event)
	{
		Tree tree = getTree();
		TreeNode node = event.getFolder();		
		TreeNode children[] = tree.getChildren(node);
		for(int i=0; i<children.length; i++)
		{
                    //here I want to select/unselect children, but did not get any method to do so.
		}
	}
}

Done by following way.

	public void onFolderClick(FolderClickEvent event)
	{
		Tree tree = getTree();
		TreeNode node = event.getFolder();
		ListGridRecord tmpRecords[] = getSelection();
		boolean isSelect = false;
		for(int i=0; i<tmpRecords.length; i++)
		{
			if(node.equals(tmpRecords[i]))
			{
				isSelect = true;
				break;
			}
		}
		TreeNode children[] = tree.getChildren(node);
		if(isSelect)
		{
			selectRecord(node);
			selectRecords(children);
		}
		else
		{
			deselectRecord(node);
			deselectRecords(children);
		}
	}
