  很多朋友问我,如何动态选择日期呢,如何选择完日期以后,关闭本页同时把日期传入上一页呢?这个问题也曾经困扰我许久,在ASP中我知道如何做,可是在ASP.NET中却有点迷惑。

  为此,我查阅了很多的资料,终于研究通了,现在分享给大家。

  源代码如下:calendar.aspx.cs

  using System;
  using System.Collections;
  using System.ComponentModel;
  using System.Data;
  using System.Data.SqlClient;
  using System.Drawing;
  using System.Web;
  using System.Web.SessionState;
  using System.Web.UI;
  using System.Web.UI.WebControls;
  using System.Web.UI.HtmlControls;
  namespace WebApplication_rd
  {
  /// 
  /// Summary description for WebForm1.
  /// 
  public class calendar : System.Web.UI.Page
  {
  protected System.Web.UI.WebControls.Label Label1;
  protected System.Web.UI.WebControls.DataGrid DataGrid1;
  private void Page_Load(object sender, System.EventArgs e)
  {
  if (! Page.IsPostBack)
  BindData();
  }
  private void BindData()
  {
  SqlConnection con = new SqlConnection("server=localhost;database=Northwind;uid=sa;pwd=;");
  SqlCommand cmd = new SqlCommand("SELECT TOP 10 * FROM Orders", con);
  try
  {
  con.Open();
  DataGrid1.DataSource = cmd.ExecuteReader();
  DataGrid1.DataBind();
  con.Close();
  }
  catch (Exception ex)
  {
  Trace.Warn(ex.Message);
  }
  }
  #region Web Form Designer generated code
  override protected void OnInit(EventArgs e)
  {
  //
  // CODEGEN: This call is required by the ASP.NET Web Form Designer.
  //
  InitializeComponent();
  base.OnInit(e);
  }
  /// 
  /// Required method for Designer support - do not modify
  /// the contents of this method with the code editor.
  /// 
  private void InitializeComponent()
  {
  this.DataGrid1.CancelCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.DataGrid1_CancelItemCommand);
  this.DataGrid1.EditCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.DataGrid1_EditItemCommand);
  this.DataGrid1.UpdateCommand += new System.Web.UI.WebControls.DataGridCommandEventHandler(this.DataGrid1_UpdateItemCommand);
  this.DataGrid1.ItemDataBound += new System.Web.UI.WebControls.DataGridItemEventHandler(this.DataGrid1_OnItemDataBound);
  this.Load += new System.EventHandler(this.Page_Load);
  }
  #endregion
  private void DataGrid1_EditItemCommand(object sender, System.Web.UI.WebControls.DataGridCommandEventArgs e)
  {
  DataGrid1.EditItemIndex = e.Item.ItemIndex;
  BindData();
  }
  private void DataGrid1_CancelItemCommand(object sender, System.Web.UI.WebControls.DataGridCommandEventArgs e)
  {
  DataGrid1.EditItemIndex = -1;
  BindData();
  }
  private void DataGrid1_UpdateItemCommand(object sender, System.Web.UI.WebControls.DataGridCommandEventArgs e)
  {
  Int32 iLastCellIndex = e.Item.Cells.Count-1; //The Index for the last cell
  String sNewDate = ((TextBox)e.Item.Cells[iLastCellIndex].FindControl("txtDate")).Text; //Get the value of the TextBox
  Label1.Text = "You set the date " + sNewDate;
  //Add database updating here
  DataGrid1.EditItemIndex = -1;
  BindData();
  }
  private void DataGrid1_OnItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
  {
  if ( e.Item.ItemType == ListItemType.EditItem )
  {
  Int32 iLastCellIndex = e.Item.Cells.Count-1; //The Index for the last cell
  String sTextBoxName = e.Item.Cells[iLastCellIndex].FindControl("txtDate").ClientID; //The rendered name of the TextBox
  String sLink = " 
  sTextBoxName +
  "'''');\">"; //The HTML to add to the Edit cell
  e.Item.Cells[iLastCellIndex].Controls.Add(new LiteralControl(sLink)); //Add the HTML
  }
  }
  }
  }

  CalendarPopUp.aspx.cs

  this.LinkButton1.Click += new System.EventHandler(this.LinkButton1_Click);
  this.Load += new System.EventHandler(this.Page_Load);
  }
  #endregion
  private void LinkButton1_Click(object sender, System.EventArgs e)
  {
  System.Text.StringBuilder sbScript = new System.Text.StringBuilder();
  sbScript.Append(""); //Closing script tag
  //Add the script to the page
  this.Page.Controls.Add(new LiteralControl(sbScript.ToString()));
  }
