describe the steps to replicate the error
Fatal error,
1. Add an RadRibbonBar Control and add a button and add an event handler onButtonClick

<telerik:RadRibbonBar runat=server ID="rb" 
        onbuttonclick="kg111_ButtonClick">
            <Tabs>
                <telerik:RibbonBarTab>
                    <telerik:RibbonBarGroup>
                        <Items>
                            <telerik:RibbonBarButton Text="Hola" Value="111"  />
                        </Items>
                    </telerik:RibbonBarGroup>
                </telerik:RibbonBarTab>
            </Tabs>
        </telerik:RadRibbonBar>

2. Add an RadDatePicker Control 
  

<telerik:RadDatePicker ID="RadDatePicker1" runat="server">
        </telerik:RadDatePicker>

3. compile and Run.
4. Select a date
5. place the cursor in the text box RadDatePicker control, or rather, place the focus on the control RadDatePicker
6. Immediately after the button click of RadRibbonBar (skip the error here)
Telerik Asp.net Version : Q1 2012
Test Browser: IE 9, Opera 11.64, Chrome, Etc

is necessary to comment that the control radribbonbar has many problems ... Telerik team, why they launched a control with too many errors and incomplete?

Hello Giancario,

Here the error is not due to the issue with RadRibbonBar,Binding a RadDatePicker control to a data source is easy provided when you use the DbSelectedDate property. It works almost like the SelectedDate one, but does not throw an exception when given a null value.

Thanks,
Princy.
