跨页面的传送

一直接查找控件

 TextBox pp_Textbox1;
        Calendar pp_Calendar1;
       
        pp_Textbox1 = (TextBox)PreviousPage.FindControl("Textbox1");
        pp_Calendar1 = (Calendar)PreviousPage.FindControl("Calendar1");

 

二将控件封装成属性

page1：

 public TextBox pp_TextBox1
    {
        get
        {
            return TextBox1;
        }
    }

    public Calendar pp_Calendar1
    {
        get
        {
            return Calendar1;
        }
    }
page2：

Label1.Text = "Hello " + PreviousPage.pp_TextBox1.Text + "<br />" +
           "Date Selected: " +
           PreviousPage.pp_Calendar1.SelectedDate.ToShortDateString();

 

或者

 if (PreviousPage != null && PreviousPage.IsCrossPagePostBack) {
        Label1.Text = "Hello " + PreviousPage.pp_TextBox1.Text + "<br />" +
           "Date Selected: " +
           PreviousPage.pp_Calendar1.SelectedDate.ToShortDateString();
      }
      else
      {
         Response.Redirect("Page1.aspx");
      }
