Cross Page Posting without PreviousPage in ASP.NET 2.0

Introducation:

Explanation:

One of the potential drawbacks to using cross page posting in ASP.NET 2.0 is that the previous page is allocated and executed through its LoadComplete event so that the target page can look at all of the re-hydrated state of the controls in the previous page to retrieve the values posted by the client.

For some reason, it never occurred to me that you don't even need to use the PreviousPage property in the target page to retrieve the values, you can simply extract the name/value pairs from the POST body directly (just as you would in classic ASP or even straight HTML).

This Article is based on the question asked in ASP .NET Forum by Swati+Jain  the thread link is http://forums.asp.net/thread/1508099.aspx

now let us see what our pages look like;

This is "FirstPage.aspx"

<form id="form1" runat="server">

<div>

<asp:ListBox ID="ListBox1" runat="server" Height="183px" Width="185px"></asp:ListBox>

<br />

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /></div>

</form>

Now "SecoundPage.aspx"

<form id="form1" runat="server">

<div>

<asp:TextBox ID="txtStartDate" runat="server"></asp:TextBox>

<br />

<asp:TextBox ID="txtEndDate" runat="server"></asp:TextBox>

<br />

<asp:Button ID="btnGod" runat="server" Text="Go" PostBackUrl="~/firstPage.aspx" Width="61px" />

</div>

</form>

Let us see how does code behind look like for "FirstPage.aspx"

protected void Page_Load(object sender, EventArgs e)

{

string str1 = Request["txtStartDate"] + Request["txtEndDate"];

ListBox1.Items.Add(str1);

protected void Button1_Click(object sender, EventArgs e)

{

Response.Redirect("secoundPage.aspx");

}
