I have the following RadDropDownTree on my page:

<telerik:RadDropDownTree ID="rddtrForeas" runat="server" 
  EnableFiltering="True"
  DefaultMessage="Select sth"
  DataTextField="Title"           
  DataFieldID="SomeId"  
  CheckBoxes="SingleCheck"            
  ExpandNodeOnSingleClick="true"  
  D
ataValueField="SomeId"  
  DefaultValue="-1" 
  DataFieldParentID="ParentId">
     <ButtonSettings ShowCheckAll="False" ShowClear="true"></ButtonSettings>
     <DropDownSettings Height="400" AutoWidth="Enabled" CssClass="mis-rddtree" OpenDropDownOnLoad="False" ></DropDownSettings><br>           
     <
FilterSettings Filter="Contains" FilterTemplate="ByText" Highlight="Matches" EmptyMessage="Write here for filtering" ></FilterSettings>
</telerik:RadDropDownTree>

In my code behind inside Page_Load  I set the DataSource to a list of three items. I then perform data bind and then set the
SelectedValue to the Ids of the first and second item.

I have noticed that if the "Title" field of my objects contains two consecutive blank spaces or ends with a blank space the drop down
tree control does not function properly. I.e. you cannot deselect in any way the node with the "problematic" title.

Try binding for example to the following list object (inside Page_Load):

List<TreeEntry> lstData = new List<TreeEntry> {
   new TreeEntry { ParentId = null, SomeId = -100, Title = "First "},
    new TreeEntry { ParentId = -100, SomeId= 39252, Title = "Some  text"},
    new TreeEntry { ParentId = -100, SomeId = 39286, Title = "Third "}
                    };
rddtrForeas.DataSource = lstData;
rddtrForeas.DataBind();
rddtrForeas.SelectedValue = "39252, 39286";

Hello Giorgos,

I setup a sample from the provided code and everything is working fine at my side. Could you please test the attached project and modify it in order to replicated the described behavior. In case that the issue appears without modifications let me know which version of the controls and browser you are using.

I added a new web form page to my existing project and copied inside it the code from my original post.
The issue is not reproducible.
 
However If I place the page containing the rad drop down tree inside a rad window that opens from another page
then the issue pops up again:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">

    function openRadWindow() {
        var oWnd;
        oWnd = $find("<%=rwDropDownTree.ClientID %>");        
        oWnd.Show();
    }
...

and

<telerik:RadWindowManager ID="rwmDialogs" runat="server" EnableShadow="true">
    <Windows>
        <telerik:RadWindow ID="rwDropDownTree" 
            runat="server"  
            NavigateUrl="~/App_WebForms/Files/PageWithRadDropDownTree.aspx"
            Modal="true"              
            InitialBehaviors="Default" 
            Width="850" Height="590">
        </telerik:RadWindow>

    </Windows>
</telerik:RadWindowManager>
