 |  Subject: How to check all child nodes when parent node is checked  Thu Mar 29, 2007 4:46 am | |
| Give a cool idea to any programmer Try this: Add the following javascript functions to your ASPX page (or ASCX or MasterPage): | Code: | function UpdateAllChildren(nodes, checked)
{
var i;
for (i=0; i<nodes.length; i++)
{
checked ? nodes[i].Check() : nodes[i].UnCheck();
if (nodes[i].Nodes.length > 0)
{
UpdateAllChildren(nodes[i].Nodes, checked);
}
}
}
function CheckChildNodes(node)
{
UpdateAllChildren(node.Nodes, node.Checked);
}
|
Then use the "AfterClientCheck" handler in your control definition:
| Code: | <radt:radtreeview
id="RadTree1"
runat="server"
AfterClientCheck="CheckChildNodes"
...
/> |
Enjoy! |
