Hello,

I tried to build in a WebDataMenu into our WebDataTree which normally was used to just select an item, postback the page with AutoPostBack-NodeClick on and load some stuff on the server to refresh controls...

Now I was running into problems, but I seem to have solved them by avoiding using client and server events (NodeClick) at the same time, as I now just use client events which themselves postback the page if nessasary.

the result is this:

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

<!--

    var lastNode = null;

    var menuClick = false;

    function treeWebDataMenu_ItemClick(menu, eventArgs) {

        menuClick = true;

        switch (eventArgs.getItem().get_key()) {

            case "makeTemplate":

                if (lastNode != null) {

                    __doPostBack('makeTemplate', lastNode.get_valueString());

                }

                break;

            case "delete":

                if (lastNode != null) {

                    __doPostBack('delete', lastNode.get_valueString());

                }

                break;

        }

    }

    function webDataTree_NodeClick(tree, eventArgs) {

        lastNode = eventArgs.getNode();

        var menu = $find("<%= treeWebDataMenu.ClientID %>");

        if (menu != null && eventArgs.get_browserEvent() != null && eventArgs.get_browserEvent().button == 2) {

            menuClick = false;

            menu.showAt(null, null, eventArgs.get_browserEvent());

        } else {

            if (lastNode != null && menuClick == false) {

                menuClick = false;

                __doPostBack('select', lastNode.get_valueString());

            }

        }

    }

// -->

</script>

<ig:WebDataTree ID="webDataTree" runat="server" SkinID="WorkplaceTree" SelectionType="Single">

    <%--OnNodeClick="NodeClicked"--%>

    <%--<AutoPostBackFlags NodeAdded="On" NodeClick="On" />--%>

    <DragDropSettings EnableDragDrop="True">

    </DragDropSettings>

    <ClientEvents NodeClick="webDataTree_NodeClick" />

</ig:WebDataTree>

<ig:WebDataMenu ID="treeWebDataMenu" runat="server" Style="margin-bottom: 0px" IsContextMenu="True">

    <Items>

        <ig:DataMenuItem Text="Als Vorlage verwenden" Key="makeTemplate">

        </ig:DataMenuItem>

        <ig:DataMenuItem Text="Löschen" Key="delete">

        </ig:DataMenuItem>

    </Items>

    <ClientEvents ItemClick="treeWebDataMenu_ItemClick" />

</ig:WebDataMenu>

------------------

everything is working as indented, BUT sometimes and really irregular I get this javascript error in the set_activeNode function:

_activeNode seems not to be what is expected at this point, but why?

the error says "_activeNode" does not support function "get_sytleElement()".

I can not 100% reproduce this error, i just comes up after 2-20 clicks in no obvious order or pattern. :(

thanks for reading :)

any help?

Carsten
