ASP.net日曆控制條件

Question

我想有一個日曆控件，只允許用戶選擇日期（週一至週五）的日期，如果它是在例如之後。當天上午9點，那麼這個日期也將不可用，然後返回到文本框中。

如何輕鬆做到這一點。我對ASP.net還很陌生。

謝謝

更新時間：

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e) 
    { 
     if (e.Day.IsWeekend == true) 
     { 
      e.Cell.Enabled = false; 
      e.Day.IsSelectable = false; 
      e.Cell.BackColor = Color.Gray; 
     } 
     else 
     { 
      e.Cell.Enabled = true; 

      if (e.Day.Date == DateTime.Today) 
      { 
       // DateTime d = DateTime.Today; 
       if (DateTime.Now.Hour > 9) 
       { 
        e.Day.IsSelectable = false; 
        e.Cell.Enabled = false; 
        e.Cell.BackColor = Color.Gray; 
       } 
      } 
      else if (e.Day.Date < DateTime.Today) 
      { 
       e.Day.IsSelectable = false; 
       e.Cell.Enabled = false; 
       e.Cell.BackColor = Color.Gray; 
      } 

     } 

    } 

更新：

<asp:Calendar ID="Calendar1" runat="server" ondayrender="Calendar1_DayRender" onselectionchanged="Calendar1_SelectionChanged" 
      ></asp:Calendar> 
     <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> 




protected void Calendar1_SelectionChanged(object sender, EventArgs e) 
     { 
      TextBox1.Text = Calendar1.SelectedDate.ToString(); 
     }

在處理事件的DayRender：

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e) 
{ 
    if (e.Day.IsWeekend == true) 
    { 
     e.Cell.Enabled = false; 
     e.Cell.BackColor = Color.Gray; 
    } 

    // add your other criteria as needed 
}

的asp.net VB的，你可以這樣做：

Protected Sub Calendar1_DayRender(sender As Object, e As DayRenderEventArgs) 
      If (e.Day.Date.DayOfWeek = DayOfWeek.Friday) Then 
       e.Day.IsSelectable = False 
       e.Cell.ForeColor = Drawing.Color.Red 
      End If 
      If e.Day.Date < System.DateTime.Today Then 
       e.Day.IsSelectable = False 
      End If 

End Sub 

這將禁用今天和週末關閉選項前的日期。
