[Solved] Radtreeview checkbox OnClientNodeChecking

[Jon Morris]

Hi,

I am using a radtreeview with a sqldatasource. The radtree looks like below:

NODE1
    Subnode1
    Subnode2
NODE2
    Subnode3
    Subnode4

I also have 4 radgrids on the page whose visibility is toggled on/off based on check/uncheck of the nodes. I achieved this by calling a javascript function on "OnClientNodeChecking". So far so good.

I also want to toggle the radgrids based on NODE1/NODE2 check/uncheck, i.e. if I uncheck NODE1, the two grids(associated with subnode1/2) should be hidden. So, I set the "CheckChildNodes" property to "True" which checks/unchecks the child nodes. I assumed that this would trigger the "OnClientNodeChecking" event for all the childs nodes. However, it doesn't. I am not sure if it is desgin issue or if I am missing something. Either way, I would appreciate if anyone can help me resolve this.

Thank you,
Sri

Hi Jon,

You can check for whether node clicked has child nodes, if yes explicitly show/hide the grids in the same handler.

JavaScript:

<script type="text/javascript">
    function OnClientNodeChecking(sender, args) {
        if (args.get_node().get_text() == 'Root RadTreeNode1') {
            if (args.get_node().get_nodes().get_count() != 0) {
                if (args.get_node().get_checked()) {
                    alert('Hide both');
                }
                else {
                    alert('Show both');
                }
            }
        }
    }
</script>
