Disabling node collapse at the client

[Lane]

Hi,

I am using the TreeView control with checkboxes, with 2 levels of nodes. I like the tri-state for the checkboxes. The list I have is short and I'd like the treeview to always be expanded - I want to hide the plus image to the left of the top node to prevent the user from collapsing any of the top level nodes. How can I do this? Seems like it should be easy to do, but I can't find the property to set.

Thanks,

Jason

Hi Jason,

Add the following CSS on page in order to hide the expand/collapse images for treenode.

CSS:

<style type="text/css">

.rtPlus

{

display: none !important;

}

.rtMinus

{

display: none !important;

}

</style>

Also the following client code willhide the expan/collapse image for the root node.

JavaScript:

<script language="javascript" type="text/javascript">

function pageLoad() {

var treeView = $find("<%=RadTreeView1.ClientID%>");

var node = treeView.get_nodes().getNode(0);

var toggleElement = node.get_toggleElement();

if (toggleElement)

toggleElement.style.display = "none";

}

</script>
