Hello
I want to change the CheckChildNodes property of the treeview in the client side in multiple situations when particular nodes are clicked. How can i do that?

Helo,

I tried the following client code in order to set the CheckChildNodes property from client.

JavaScript:

function setProperty() {
        var treeView = $find('<%=RadTreeView1.ClientID%>');
        treeView._checkChildNodes = false; // Set the value
    }

Regards,

Shinu.

Hi NLV,

Please take a look at this help topic. In the bottom of the page is presented some way to check all child nodes when checking their parent in Javascript:

var expandedNodeChecked = null;

function onClientNodePopulated(sender, eventArgs)
{
if (expandedNodeChecked != null)
{
 var parentNode = eventArgs.get_node();
 var childNodes = parentNode.get_nodes();
 var childNodeCount = childNodes.get_count();

 for (var nodeIndex = 0; nodeIndex < childNodeCount; nodeIndex++)
 {
  var childNode = childNodes.getNode(nodeIndex);

  childNode.set_checked(expandedNodeChecked);
 }
}
}
function onClientNodePopulating(sender, eventArgs)
{
expandedNodeChecked = eventArgs.get_node().get_checked();
}

Hi Veronica Milcheva

Thanks for your reply. But i think looping is not gonna work if the childeNodeCount is very large.

@shinu - Let me try out the solution you gave. I previously tried it as

$find('<%=RadTreeView1.ClientID%>').CheckChildNodes = false

and it dint work!
