[轉]Calendar 控制項日期複選－冠霖的部落格

Calendar 控制項可以透過 SelectedDate 屬性來取目前選取的日期，不過它沒有提供日期複選的功能。為達到日期複選的功能，我們在 DayRender 事件中，為每一個日期儲存格加入一個 HtmlInputCheckBox 控制項做日期選取，當 PostBack 時再透過 Request.Form 來取得用戶端複選的日期。

Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Calendar1_DayRender(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DayRenderEventArgs) Handles Calendar1.DayRender
Dim oCheckBox As New HtmlControls.HtmlInputCheckBox()
oCheckBox.Value = e.Day.Date.ToShortDateString
oCheckBox.ID = "SelectDate"
e.Cell.Controls.Clear()
e.Cell.Controls.Add(oCheckBox)
e.Cell.Controls.Add(New LiteralControl(e.Day.DayNumberText))
End Sub
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Response.Write("SelectDate: " & Me.Request.Form("SelectDate"))
End Sub
End Class

        e.Cell.Controls.Add(oCheckBox)
        e.Cell.Controls.Add(New LiteralControl(e.Day.DayNumberText))
    End Sub

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.Response.Write("SelectDate: " & Me.Request.Form("SelectDate"))
    End Sub
End Class
