Hi Johan Bjerling,
Thank you for the questions.
RadDateTimePicker does not support picking up only a date from a dropdown. Currently, we do not have certain plans about developing such feature, but if more customers request it, we will raise its priority.
As to your second question, you can limit the range of dates by setting MinDate and MaxDate properties of the RadDateTimePickerEditorElement in the CellEditorInitialized event handler. An example of setting properties in the CellEditorInitialized event handler is placed in this help article. In your case the code for setting MinDate and MaxDate will look like this:
sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
RadDateTimeEditor editor =
DateTime(2009, 01, 01);
DateTime(2009, 12, 12);
I hope this helps. If you have additional questions, feel free to contact me.
