Client side events not working after creating a wrapper over Telerik.Web.UI.RadDatePicker

[Gun]

I have a wrapper class over RadDatePicker.

public class DatePicker : Telerik.Web.UI.RadDatePicker

{

    public DatePicker()

        : base()

    {

        //

        // Some code her

        //

    }

}
Now, I have my own implementation here. I want to use the event's like DateInput-ClientEvents-OnBlur:

<tele:DateTimePicker id="date" runat="server" autopostback="true" DateInput-ClientEvents-OnBlur="alert('Ding');"/>

But, I couldn't get it working. Not getting what did I miss.
Thanks.

Hi,

Please try to attach the OnBlur event of RadDatePicker as follows.

ASPX:

<telerik:RadDatePicker ID="date" runat="server" AutoPostBack="true" DateInput-ClientEvents-OnBlur="Blur" />

JavaScript:

function Blur() {
    alert("fired");
}

Thanks,
Shinu.

I tried that before. But this event gets appended to the <span> element.

<span style="display: inline-block; width: 115px;" dateinput-clientevents-onblur="alert('Ding');"
          class="datepickerstyles" id="Span1"><span style="display: none;" class="readonlylabel readonlydatetimelabel"
                                                    title="15/10/2013 ">15/10/2013 </span>
                                                    <!--SOME HTML-->
        <input type="text" style="width: 100%;" class="riTextBox riEnabled datepickerstyles"
            name="ctl00_DialogContent_dtpDate_InternalRadDatePicker1_dateInput_text" id="ctl00_DialogContent_dtpDate_InternalRadDatePicker1_dateInput_text"
            value="15/10/2013" maxlength="2147483647">
    </span>

I don't get it why is the vent getting appended to the span element.
