Hello Ali,

You can achieve this, by getting reference to UserControl and then the embedded RadDatePicker by using FindControl() method; then set the SelectedDate property of RadDatePicker.

C#:

 protected void Button1_Click(object sender, EventArgs e)
    {
        UserControl uc = (UserControl)this.FindControl("UserControl_DatePicker1");
        RadDatePicker datepicker = (RadDatePicker)uc.FindControl("rdDate");
        DateTime dt = new DateTime(2009, 1, 24);
        datepicker.SelectedDate = (DateTime)dt;
    }

Regards,
Shinu.

Hello Ali,

To achieve the desired functionality you could try setting the ClientID of the RadDatePicker to the javascript variable on the usercontrol's Page_Load event handler:

protected void Page_Load(object sender, EventArgs e)
{
     ScriptManager.RegisterStartupScript(Page, Page.GetType(), "registedID", "datepickerID = '" + RadDatePicker1.ClientID + "';", true);
}

Then when the button is clicked you could find the RadDatePicker and set the date:

<asp:Button ID="Button1" runat="server" Text="Set Date" OnClientClick="SetDate(); return false;" />

<telerik:RadCodeBlock runat="server" ID="sdf">

  <script type="text/javascript">

       var datepickerID;

       function SetDate()

        {


               var datePicker = $find(datepickerID);

                 datePicker.set_selectedDate(new Date());

            }

    </script>

 </telerik:RadCodeBlock>

Additionally I am sending you a simple example which demonstrates how to achieve the desired functionality.

Thanks for your reply. but "$find(datepickerID);" is not working for me. it returns null value.

Any other suggestion please.

Hi Ali,

Could you please verify that on Page_Load you register startup script which set the RadDatePicker1.ClientID to the client datepickerID variable, like in my example. The $find(datepickerID); function will return null if you do not initialize the datepickerID via ScriptManager.RegisterStartupScript method in code behind.

Kind regards,

yes sir. i confirm that i register it as you said. and when i debug javascript "datepickerID " does not return null or undefined. but when i use $find(datepickerID ) it returns null. i dont know why.

Please help... thanks

Hello Ali,

Could you please post your aspx page within the code behind or open a support ticket and send us a small runnable project which demonstrates the issue. You could open a formal support ticket from your Telerik account and attach a ZIP file there.  In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.

All the best,
