I have a row of items, including a RadTimePicker with a TimePopupButton. If I click the popup, and then click the mouse out of the popup, the popup closes. If instead of clicking I use the tab key, the popup stays open until I click somewhere. Is this intentional behavior, and if so is there a way to change it so the popup closes when the tab button is used to alter the input focus? Here's the RadTimePicker definition I currently have.
<telerik:RadTimePicker ID="SurgeryTime" runat="server" MinDate="1780-01-01" Culture="English (United States)" Width="80" style="margin-right: 15px;" >
<TimePopupButton CssClass="" />
<TimeView ID="TimeView1" StartTime="1:0:0" EndTime="23:00:00" Interval="0:15:0" Columns="5"
TimeFormat="HH:mm" runat="server">
</TimeView>
<DateInput ID="DateInput1" DateFormat="HH:mm" runat="server">
</DateInput>
<Calendar UseColumnHeadersAsSelectors="True" UseRowHeadersAsSelectors="True" runat="server">
</Calendar>
<DatePopupButton CssClass="" Visible="False" />
</telerik:RadTimePicker>
