I have static Treeview control which is basically about country and states list.
In the treeview i am checking the nodes from the code behind if the values exits in
the database.
This is working fine and i have all the parent and child nodes checked. I have written
a javascript code to CHECk - UNCHECK all the Child nodes if parent node is UNCHECKED
or checked.
The problem i am facing is the Javascript(alert(bChecked )) does not recognise the
node as CHECKED or UNCHECKED if the node has been CHECKED from CODE BEHIND
If the node is not CHECKED from code behind, the javascript function is able to
recognise the node as checked or unchecked
in page load i have added the below code TreeGeos.Attributes.Add("oncheck",
"TreeClicked(this);")
<script language="javascript">
function TreeClicked(oTree)
{
DirtyTrue();
// Get the node that fired the event...
var bChecked;
var oNodeClicked = oTree.getTreeNode(oTree.clickedNodeIndex);
var bChecked = oNodeClicked.getAttribute("checked");
alert(bChecked )
var oColl = oNodeClicked.getChildren();
TraverseChildren(oColl, bChecked);
}
function TraverseChildren(oColl, bChecked)
{
var oChild;
for (var i=0;i<oColl.length;i++)
{
oChild = oColl[i];
oChild.setAttribute("checked", bChecked);
}
}
</script> Please let me know how to fix this problem. The javascript code is
transversing the whole Treeview control, and this i use for the requiredfield
validator, to ensure atleast one node is checked. i have some code for that.
But the main prob is the javascript does not recognize the node check uncheck if the
node already has attribute checked, which was set from code behind <tvns:treenode
Checked="true" CheckBox="True" ID="265">
Alaska
</tvns:treenode>
Thanks Girish
