RadDateTimePicker SelectedValue does not change when user clears input

[Thomas]

I have a RadDateTimePicker control in a view that is bound to a datetime property in the associated viewmodel using the SelectedValue of the RadDateTimePicker. When the user selects a date and / or time, the datetime property in the viewmodel is set accordingly. However, if the user subsequently clears the input and the default 'Enter date' text is displayed in the control, the datetime property in the viewmodel is not set to null / mindatetime.

How can I implement the RadDateTimePicker so that if a user clears the datetime from the control the SelectedValue becomes null or mindatetime?

I have managed to handle this by also binding a property in the viewmodel to the DateTimeText property of the control and checking for blank. it is a bit of a pain having to do this. Please can we have it so that RadDateTimePicker SelectedValue becomes null when user clears input from the control.

Hello Thomas,

You should define the DateTime property in the View-Model like this:

private DateTime? selectedDate;

public DateTime? SelectedDate
{
    set { this.selectedDate = value; }
    get  {return this.selectedDate; }
}

and then bind it to the DateTimePicker:

<telerikInput:RadDateTimePicker SelectedValue="{Binding SelectedDate, Mode=TwoWay}"/>

Please try it and let us know the result.

All the best,
