So for this article first I have created an asp.net application and add the two pages in the application. Now on page one add the below code.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Page1.aspx.cs"
Inherits="WebApplication7.Page1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Page 1</title>
</head>
<body>
<form id="form1" runat="server">
<h3>Click Button To
Pass Value</h3>
Enter
Value :<asp:TextBox ID="txtValue" runat="server" Width="201px"></asp:TextBox>
<br />
<br />
<div>
<asp:Button ID="Button1" runat="server" Text="By Request Querystring" OnClick="Button1_Click"
Width="203px" />
<br />
<br />
<asp:Button ID="Button2" runat="server" Text="By Session"
Width="204px" OnClick="Button2_Click"
/>
<br />
<br />
<asp:Button ID="Button3" runat="server" Text="By HiddenField" Width="201px" PostBackUrl = "Page2.aspx"/><br />
</div>
</form>
</body>
</html>
|
In above code I have taken three button controls. Each button represents a way to transfer the data. In above I have passed the textbox value from one page to other page. As you execute the page1 your page will look as shown below.
Now have a look of the below code.
Way 1:
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("Page2.aspx?value=" + txtValue.Text);
}
|
In above code I have used request querystring to pass the value.
Way2:
protected void Button2_Click(object sender, EventArgs e)
{
Session["Value"] = txtValue.Text;
Response.Redirect("Page2.aspx");
}
|
In above I have used session to pass the value to other page.
Way3:
<asp:Button ID="Button3" runat="server" Text="By HiddenField" Width="201px" PostBackUrl = "Page2.aspx"/>
|
In above I have used PostBackUrl to pass the value and access it on other page. Now we will check the code for page2.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Page2.aspx.cs"
Inherits="WebApplication7.Page2" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Page 2</title>
</head>
<body>
<form id="form1" runat="server">
<div>
Request Querystring :<asp:Label ID="Label1" runat="server" Text=""></asp:Label><br />
Session Value :<asp:Label ID="Label2" runat="server" Text=""></asp:Label><br />
Http
Post:<asp:Label ID="Label3" runat="server" Text=""></asp:Label><br />
</div>
</form>
</body>
</html>
|
Now have a look
the below code of page2 access the pass value.
Way1 To
access:
if (Request.QueryString["value"] != null)
{
Label1.Text = Request.QueryString["value"].ToString();
}
|
Now press F5 to check the output.
if (Session["value"] != null)
{
Label2.Text = Session["value"].ToString();
}
|
Now press F5 to access the value.
if (Request.Form["txtValue"] != null)
{
Label3.Text = Request.Form["txtValue"].ToString();
}
|
Now press F5 to check the output.
