Hello all,
New user to Telerik controls here. Question on RadTree...is it possible to enable multi-select, but restrict selections to a given node? And only the immediate children of that node?
So for example, if there are 3 parent nodes, each with 5 child nodes. If a user select 2 child nodes of Parent 1, but then selects a child node of parent 2, all the selected nodes in Parent 1 would be unchecked. The user could continue to multi-select children in Parent Node 2. And so on.
Any help is appreciated. Thanks in advance.

Hi Albert Pernia,
Try the following client-side code to accomplish the functionality.
JavaScript:
<script type=
"text/javascript"
language=
"javascript"
>
function
ClientNodeChecked(sender, eventArgs)
{
var
tree = sender;
var
node = eventArgs.get_node();
var
parentNode=node.get_parent();
for
(j=0;j<tree.get_checkedNodes().length;j++)
{
if
(tree.get_checkedNodes()[j].get_parent().get_text()!=node.get_parent().get_text())
{
tree.get_checkedNodes()[j].set_checked(
false
);
j--;
}
else
{
tree.get_checkedNodes()[j].set_checked(
true
);
}
}
}
</script>

Ah, yes, thank you very much, that works perfectly. I started to play around with the client-side functionality when I realized there was no property in the RadTree you could set to restrict the selections. But this saves me the trouble. Thanks alot!
