Hello Kenghot,

You should handle KeyPress event instead of KeyDown event because the Enter key is processed in different way. Consider the sample below:

Private Sub IctDateTimePicker1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles IctDateTimePicker1.KeyPress
                If Asc(e.KeyChar) = 13 Then
                    SendKeys.SendWait("{TAB}")
                End If
End Sub

I hope it helps. Don't hesitate to contact us, if you have further questions.

Kind regards,

Hi Shoshana,  

Thank you for contacting Telerik support.

You should handle the hosted textbox control
KeyDown Event:
this.radDateTimePicker1.DateTimePickerElement.TextBoxElement.TextBoxItem.HostedControl.KeyDown += new   KeyEventHandler(HostedControl_KeyDown);
 
 
 void HostedControl_KeyDown(object sender, KeyEventArgs e)
 {
      
 }
I hope this helps.

All the best,
Peter

Hi,
Thanks for your reply,
but this code works only when subscribe to the event out of the DateTime class,
but when I write this code, its does not work

public DateTimePickerBaseTest()
           : base()
       {
           this.DateTimePickerElement.TextBoxElement.TextBoxItem.HostedControl.KeyDown += new KeyEventHandler(HostedControl_KeyDown);
       }
 
       void HostedControl_KeyDown(object sender, KeyEventArgs e)
       {
           if (e.KeyData == System.Windows.Forms.Keys.Delete)
           {
               this.SetToNullValue();
 
               //this.OnNotifyPropertyChanged("BindableValue");
 
               e.Handled = true;
           }
 
           else
               base.OnKeyDown(sender, e);
       }


I'd be happy to use your help again,
Shoshana

Hi Shoshana,

Thank you for writing back.

I guess at this point the textbox is not yet initialized. 
I would like to recommend you to subscribe to the event in the OnLoad override:
protected override void OnLoad(System.Drawing.Size desiredSize)
{
            base.OnLoad(desiredSize);
            this.DateTimePickerElement.TextBoxElement.TextBoxItem.HostedControl.KeyDown += new KeyEventHandler(HostedControl_KeyDown);
}

I hope this helps.
