    We have a listbox with SelectionMode="Multiple" turned on, however when you select multiple items it also selects other parts of the screen and manages to select other parts of the screen, it selects from the listbox too but everything selected goes blue as expected but lots of screen does too,

    I hope you can help.

    telerik:RadListBox ID="radOrderID" runat="server" Width="900px" Height="200px" EmptyMessage="Select an Order"
                                Skin="Outlook" SelectionMode="Multiple" AutoPostBack="true">
                                    <table cellspacing="0" cellpadding="0" class="multicomboBoxOrder">
                                            <td class="col1">
                                                <%#DataBinder.Eval(Container.DataItem, "OrderNo")%>
                                            <td class="col2">
                                                <%#DataBinder.Eval(Container.DataItem, "Description")%>
                                            <td class="col3">
                                                <%#DataBinder.Eval(Container.DataItem, "CustomerHeaderRef")%>
                                            <td class="col4">
                                                <%#DataBinder.Eval(Container.DataItem, "Department")%>
                                            <td class="col5">
                                                <%#Format(DataBinder.Eval(Container.DataItem, "OutstandingValueToInvoice"), "0.00")%>
                                            <td class="col6">
                                                <%#Format(DataBinder.Eval(Container.DataItem, "OutstandingValueToInvoiceShipped"), "0.00")%>
                                            <td class="col7">
                                                <%#DataBinder.Eval(Container.DataItem, "CurrencySell")%>
                                            <td class="col8">
                                                <%#DataBinder.Eval(Container.DataItem, "OrderSource")%>

    Hello Jonathan,

    I guess you are talking about the case where you use the Shift key to select multiple items. This triggers the default browser behavior, which is responsible for selecting the items on the page. Unfortunately this is out of our scope and we cannot prevent it.

    For anyone else who has this problem and stumbles across this page, I found that this javascript in my pageLoad() function fixed the behavior for me. 

    window.onload = function () {
                    document.onselectstart = function () {
                        return false;

    However, as it is, it disables all text selection on the entire webpage.
