设置最小和最大的日历日期？ [英] Setting minimum and maximum date on Calendar?

问题描述

我有一个环顾四周，再次，找不到如何设置允许在ASP.net日历用VB选择的最小和最大的日期。

I've had a look around, once again and can't find how to set the minimum and maximum dates allowed to be selected on a calendar in ASP.net with VB.

我使用Visual Studio 2010和它只是此刻定期日历控件...

I'm using Visual Studio 2010 and it's just a regular Calendar control at the moment...

目前，我已经看到了这样的话：

At the moment I've seen things like:

Calendar1.DateMin = DateTime.Now

但是，Visual Basic中似乎并不喜欢（也许这是一个C＃的东西？）......总之，如果有一种方法可以做到这一点，将是一个很大的帮助！

But Visual Basic doesn't seem to like that (maybe it's a C# thing?)... Anyway, if there's a way to do this it'll be a great help!

推荐答案

您需要处理日历的的 的DayRender 事件：

You need to handle the Calendar's DayRender event:

Private MinDate As Date = Date.MinValue
Private MaxDate As Date = Date.MaxValue

Protected Sub Calendar1_DayRender(sender As Object, e As DayRenderEventArgs)Handles Calendar1.DayRender
    If e.Day.Date < MinDate OrElse e.Day.Date > MaxDate Then
        e.Day.IsSelectable = False
    End If
End Sub

然后你可以在设置例如的Page_Load ：

MinDate = Date.Today
MaxDate = MinDate.AddDays(7)
