You can use javascript to set the SelectedDate property of “To Date” Calendar in OnClientShowing event. This is how you can do this:

in markup:

<cc1:CalendarExtender ID="toDate" runat="server" TargetControlID="txtDate" Format="MM/dd/yyyy" OnClientShowing="setDefaultDate" />

in javascript:

function setDefaultDate(sender,args)
{
    if(sender._textbox.get_element().value == "")
    {
        var selectedDate = new Date(); //here i am using current date but you can get the selected date of From Calendar control and add +2 days
        sender._selectedDate = selectedDate;
    }
}
