WebInput version we are using is 3.0.7200.213

I am trying to set empty or null data for a control and I can't use any key (like delete, backspace) to delete the date that is already entered into the control. This is driving me crazy.. so please help

Here is the sinpet of code I am using to add webInput dynamically in my form.

	WebInput ctrl = (WebInput) foundation;
	ctrl.BorderStyle = BorderStyle.Inset;
	ctrl.BorderWidth = 1;
	ctrl.DateTimeEditor.IsEnabled = true;

	ctrl.HighLight.IsEnabled = true;
	ctrl.HighLight.Type = HighLightType.Phrase;

	ctrl.DisplayFormat.IsEnabled = true;
	ctrl.DisplayFormat.Format = 		Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern;
	ctrl.DateTimeEditor.MinDropDownYear = 1900;
	ctrl.DateTimeEditor.MaxDropDownYear = 2100;

I tried adding the following 2 lines, it DID NOT help, I have no idea where the heck is checkbox is to set null (as per the code below)

ctrl.ShowCheckBoxForNullInput = true;ctrl.EditFormat.MaskInfo.SaveBlanks = true;

 
 
Anyway I am sure you can help me here.
 
Thanks
