passing value between pages

Hi Am trying to pass data back and forth between 2 web forms in asp.net I tried the Get property but facing issues when trying to return control from Page 2 to Page 1. Am not sure what is going wrong. The scenario that I would like to create is Page 1 click button --> pass values --> Page 2 (capture passed value) Page 2 click button --> pass values --> Page 1 (capture passed value) Attached below is the code snippet that I am using : WebForm1.aspx ( PAGE 1) ----------------------- public string Property1 { get { return TextBox1.Text; } } private void Page_Load(object sender, System.EventArgs e) { // Put user code to initialize the page here if (!IsPostBack) { } else { WebForm2 wf2 = (WebForm2) Context.Handler; Label1.Text = wf2.Property2; } } private void Button1_Click(object sender, System.EventArgs e) { Server.Transfer("Webform2.aspx"); } WebForm2.aspx ( PAGE 2) ----------------------- public string Property2 { get { return Label1.Text; } } private void Page_Load(object sender, System.EventArgs e) { // Put user code to initialize the page here if (!IsPostBack) { WebForm1 sourcepage = (WebForm1) Context.Handler; Label1.Text = sourcepage.Property1; } } #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.Button1.Click += new System.EventHandler(this.Button1_Click); this.Load += new System.EventHandler(this.Page_Load); } #endregion private void Button1_Click(object sender, System.EventArgs e) { Server.Transfer("Webform1.aspx",true); } The above code worked fine when I navigate from Page 1 to Page 2, but when it tries to navigate back to page1 - it fails ! Can you pls help ? Thanks

Hi Krishis, You'll need to make 2 changes in your code. One in Page_Load event of WebForm1.aspx.cs. Instead of doing like this: if (!IsPostBack) { } else { WebForm2 wf2 = (WebForm2) Context.Handler; Label1.Text = wf2.Property2; } do something like this: if (!IsPostBack) { if(Request.RawUrl.Substring(Request.RawUrl.LastIndexOf('/') + 1) == "Webform2.aspx" ) { WebForm2 wf2 = (WebForm2) Context.Handler; Label1.Text = wf2.Property2; } } this will make sure that this part of code is called only once when request is coming from Webform2.aspx and not on every post back. Second change you'll need to do is in Button1_Click event of WebForm2.aspx.cs, instead of using Server.Transfer("Webform1.aspx",true); use Server.Transfer("Webform1.aspx"); Cheers, Yasser
