[Solved] Menu casuing treeview to hide when opening window

[Greg Lynne]

When you use a telerik menu item in conjunction with a telerik treeview and telerik window, the window opening from the menu cause the treeview to dissapear.

Original:

<ul class="t-group t-treeview-lines"><li class="t-item t-first"><div class="t-top"><span class="t-in t-state-selected"> And LOS <= 15</span><input type="hidden" value="" name="itemValue" class="t-input"></div></li><li class="t-item t-last"><div class="t-bot"><span class="t-in">new ...</span><input type="hidden" value="" name="itemValue" class="t-input"></div></li></ul>

Changes to after call to window open: Note: wraps it in t-animation-container

<div class="t-animation-container" style="width: 280px; height: 45px; display: none;"><ul class="t-group t-treeview-lines" style="margin-left: -280px;"><li class="t-item t-first"><div class="t-top"><span class="t-in t-state-selected"> And LOS <= 15</span><input type="hidden" value="" name="itemValue" class="t-input"></div></li><li class="t-item t-last"><div class="t-bot"><span class="t-in">new ...</span><input type="hidden" value="" name="itemValue" class="t-input"></div></li></ul></div>

I am currently working around this issue by using the ".OpenOnClick(true)" function

Please see screen shots for more info:

This bug still occurs even when implementing .OpenOnClick(true).
Notice that the "Helper" menu item below is just calling a javascript alert(), however this still causes any MVC treeviews on the loaded page to dissapear, by being wrapped by:
<div class="t-animation-container" style="width: 0px; height: 0px; display: none;">

<%= Html.Telerik().Menu()
     .Name("ActionMenu")
     .OpenOnClick(true)
     .Items(menu =>
                    {
                        menu.Add()
                            .Text("Insert")
                            .Items(item =>
                                       {
                                           item.Add().Text("Calculation Contract Number").Url(url);
                                           item.Add().Text("Helper").Url("javascript:alert('Not implemented');");
                                       });
                    })
    %>

If you need any other examples then let me know.

Hello Andrew,

I tried to reproduce the problem but to no avail. It might be related to a specific setup, but without having a better view over your exact configuration and logic, I cannot be sure. Could you please provide a sample project so we can investigate further?

Thank you in advance for your cooperation.
