I am trying to loop through and expand ALL using an example I saw on the forum but it only expands the first level no matter what I set the “Level” to.


function Menu1Click(e, info)
{
//var group = info.getItem().getParentGroup();
switch (info.getItem().getText())
{
case "Expand All":
toggleLevel(eo_GetObject('TreeView1').getTopGroup(), 0, true);

break;
case "Collapse All":
toggleLevel(eo_GetObject('TreeView1').getTopGroup(), 0, false);
break;
}
}



function toggleLevel(group, level, show)
{
for (var i = 0; i < group.getItemCount(); i++)
{
var item = group.getItemByIndex(i);
if (group.getLevel() <= level)
item.setExpanded(show);
else
{
var subGroup = item.getSubGroup();
if (subGroup)
toggleLevel(subGroup, level, show);
}
}
}

Hi,

Try to change:

Code: JavaScript
if (group.getLevel() <= level)
    item.setExpanded(show); 
else
{
    var subGroup = item.getSubGroup();
    if (subGroup)
        toggleLevel(subGroup, level, show);
}


To:

Code: JavaScript
if (group.getLevel() <= level)
    item.setExpanded(show); 

var subGroup = item.getSubGroup();
if (subGroup)
    toggleLevel(subGroup, level, show);


That should get it going.

Thanks
LLJames
