    Hi, if I open a RadDropDownTree and then I press enter to automatically select all the items.


                                                        <telerik:RadDropDownTree RenderMode="Lightweight" ID="RadDropDownTree3" runat="server" Width="100%" CheckBoxes="TriState"
                                                            DefaultMessage="Seleziona la zona" OnNodeDataBound="RadDropDownTree1_NodeDataBound" Skin="Bootstrap" >
                                                            <DropDownSettings />


    You can avoid this behavior ?

    Could you, please explain, what you are trying to achieve? Do you want to prevent the closing of the drop-down after nodes have been selected or something else? If you want to prevent closing you could use the OnClientDropDownClosing event of the widget:
    var cancelClosing = true;
    function dropDownClosing(sender, args) {
        cancelClosing = false;

    Keep in mind that you will have to implement your own custom logic to prevent closing under the conditions needed. Otherwise you won't be able to close the drop-down at all.
