Problem with treeview

[Alessandro Di Rago]

I have a treeview's tree:

<form id="showtree" name="showtree" method="post" runat="server">
<iewc:TreeView id="TreeView" runat="server" AutoPostBack="true"
SelectExpands="false" EnableViewState="True" Width="1000px"></iewc:TreeView>
</form>

i wish create a javascript's function that, on the onclick event, give me
the attribute of the clicked node. Someone know how developed this
javascript function?
Thank you

Hi,

Node has a property called NavigateURL. Set this to the
javascript function.

Meanwhile, which attribute of the clicked node are you
interested in? Let me and I can help you with the js
function.

Cheers!

Hi,

Try with the NavigateURL property of Node. Set the
navigateurl to "javascript:myfunction('nodenamehere');".
In your page have a function:
<script language=javascript>
function myfunction(node){
alert(node);
}
</script>

try this.. should work.

Cheers!

Hi,

Try with the NavigateURL property of Node. Set the
navigateurl to "javascript:myfunction('nodenamehere');".
In your page have a function:
<script language=javascript>
function myfunction(node){
alert(node);
}
</script>

in navigateurl property i have already a link, take to the database. i found
this function:

function myfunc()
{
var SelectedNode;
// This gives you the node that is clicked
SelectedNode=TreeView1.getTreeNode
(TreeView1.clickedNodeIndex);
// just checks and returns a property of the node
if (SelectedNode!=null)
{
alert(SelectedNode.getAttribute("text"));
}
}

<form id="showtree" name="showtree" method="post" runat="server">
<iewc:TreeView id="TreeView" runat="server" AutoPostBack="true"
SelectExpands="false" EnableViewState="True" Width="1000px"></iewc:TreeView>
</form>

But it does not work, the error is generated on
"SelectedNode=TreeView1.getTreeNode(TreeView1.clickedNodeIndex);"

Try this.
in the code behind :
TreeView1.Attributes.Add("onselectedindexChange", "mafonction();")

And in the page:
<script language="javascript">
function mafonction(){
SelectedNode = event.srcElement.getTreeNode(event.treeNodeIndex);
SelectedNode.getAttribute('nodedata');
}
</script>

Try this.
in the code behind :
TreeView1.Attributes.Add("onselectedindexChange", "mafonction();")

And in the page:
<script language="javascript">
function mafonction(){
SelectedNode = event.srcElement.getTreeNode(event.treeNodeIndex);
SelectedNode.getAttribute('nodedata');
}
</script>

When i click on the node, with the onselectedindexChange event, it not work
nothing. I use the onclick event:
TreeView1.Attributes.Add("onclik", "mafonction();")
in this way, when i click on the node, is called the js function but is
generated an error on the
"event.srcElement.getTreeNode(event.treeNodeIndex);". The error is method
not supported by object.
Why?

Hi,

I have not read all here, but regard, in JScript, the event-name is
case-senstive is is named "onselectedindexchange". This works for me!
