推荐答案

请遵循这个例子和修改code。希望它能帮助。

Please follow this example and modify your code. Hope it helps.

<asp:UpdatePanel id="UpdatePanel1" runat="server">
<contenttemplate>
<cc2:CalendarPopup id="CalendarExtender1" runat="server" Width="71px" OnDateChanged="CalendarPopup1_DateChanged" AutoPostBack="True"></cc2:CalendarPopup>
<cc2:CalendarPopup id="CalendarExtender2" runat="server" Width="71px"></cc2:CalendarPopup>
</contenttemplate>
</asp:UpdatePanel>        

**Code behind:**

 protected void CalendarPopup1_DateChanged(object sender, EventArgs e)
    {
        CalendarPopup2.SelectedDate = CalendarPopup1.SelectedDate.AddDays(1); // you can add the number of days you want
    }
