    [CLOSED] Treepanel root visible

    Hi,

    In v1.x I perform this to set root node visibility.

    myTree.rootVisible = true || false; //My custom condition
myTree.setRootNode(node);
    Now, with myTree with property RootVisible setted to false in ASPX markup, although I change this value like in the example, when treepanel redraw in setRootNode, doesn't shows me root node when condition is true.

    How I can do this now, I don't see any method in ext docs.

    Hi,

    Well, it is not documented behavior in ExtJS 3. The rootVisible property is private.
    http://docs.sencha.com/ext-js/3-4/#!...ty-rootVisible

    I can't see an API possibility to do it in ExtJS 4 as well, but I can suggest the following solution.

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!DOCTYPE html>

<html>
<head runat="server">
    <title>Ext.NET v2 Example</title>

    <script type="text/javascript">
        var setRootNode = function () {
            var tree = App.TreePanel1,
                view = tree.getView(),
                newRoot = {
                    text : "new root",
                    leaf : true
                };

            view.rootVisible = view.store.rootVisible = true;
            tree.setRootNode(newRoot);
            view.refresh();
        };
    </script>
</head>
<body>
    <ext:ResourceManager runat="server" />

    <ext:TreePanel 
        ID="TreePanel1" 
        runat="server" 
        RootVisible="false" 
        Height="100">
        <Root>
            <ext:Node Text="Root" Leaf="true" />
        </Root>
    </ext:TreePanel>

    <ext:Button runat="server" Text="setRootNode">
        <Listeners>
            <Click Fn="setRootNode" />
        </Listeners>
    </ext:Button>
</body>
</html>

    Great!

    This piece of code do the trick:

    var view = treeOrganigrama.getView();
view.rootVisible = view.store.rootVisible = nodeId > 0;
treeOrganigrama.setRootNode(node);
    Thanks!
