Sending values to multiple pages

Question

1.50/5 (2 votes)

See more:

I have a query related to posting values from HOMEPAGE to 2/3 other pages in background.

e.g.: If user clicks on a link the same values must go to multiple pages

User clicks on a link X which will post values x=1, y=2, z=3

So in HOMEPAGE we get these values x=1, y=2, z=3

NOW I want the same values

C#

x=1, y=2, z=3

to be available in other pages of the site page1.aspx.cs and page2.aspx.cs

So how can i pass values from Homepage to Page1.aspx.cs and page2.aspx.cs

I've already tried sending using session / response.write from the homepage, but the values are not available in Page1.aspx.cs and page2.aspx.cs

In page 2

C#

protected void Page_Load(object sender, EventArgs e)
{
    Response.Clear();
    Response.Write("Ths is the response from two.aspx: " + Request.Form["MyData"]);
    Response.End();
}

Where I see the value in page1.aspx.cs or page2.aspx.cs I see MYdata= " " NULL

in Default page

C#

<asp:TextBox ID="txtData" runat="server" />
<asp:Button ID="cmdSend" Text="Send" runat="server" />
<div id="resulta"></div>
<div id="resultb"></div>
 
<script type="text/javascript">
    function sendData(txt)
    {
        var c = $("#" + txt);
 
        makeCall("<%=Page.ResolveUrl("~/one.aspx") %>", c.val(), $("#resulta"));
        makeCall("<%=Page.ResolveUrl("~/two.aspx") %>", c.val(), $("#resultb"));
 
        return false;
    }
 
    function makeCall(url, text, target)
    {
        $.ajax({
            type: "POST",
            url: url,
            data: { myData: text },
            contentType: "application/x-www-form-urlencoded; charset=UTF-8",
            dataType: "text",
            success: function (data) {
                target.html(data);
            }
        });
 
    }
</script>

Can you share what have you tried and where exactly you are getting problem?

Avik Ghosh22 21-Jan-16 0:36am

you can store data either cookies or session to send data from one page to other pages .

aarif moh shaikh 21-Jan-16 1:16am

use session for this

Sinisa Hajnal 21-Jan-16 2:53am

Session.

F-ES Sitecore 21-Jan-16 7:00am

What's going to happen in the browser? Do you redirect the user to one of these pages? Or do you just want the data sent in the background? Or do you want the pages to open in new windows\tabs? You'll need to give a bit more information on what it is you're trying to achieve.

I just want to send data to other pages in the background..
The reason behind sending the data in the background is to capture some of the values... e.g: Name,type and UID

Based on these values we will be able to create -

UNIQUE FOLDER for user - UID
NAME - Which division
Type - Which Type of Folder (eg: Read / Write )

If you want to store values from one page to other pages you can use two methods.
1) session
2) cookie
Based on the requrirement you can select one of these location and store the values accordingly.

Hi,

First of all question is not clear about what you want and what have you tried to resolve your problem.

You have few options as per my understanding. Using Query string is one among them.

Using a Query String:
When you use a hyperlink or Response.Redirect to navigate from one page to another, you can add information in a query string at the end of the URL.

1. In the source Web Forms page when you specify the URL of the target page, include the information that you want to pass in the form of key-value pairs at the end of the URL. The first pair is preceded by a question mark (?) and subsequent pairs are preceded by ampersands(&), as shown in the following example:

http://contoso.com/products.aspx?field1=value1
http://contoso.com/products.aspx?field1=value1&field2=value2

2. In the target page, access query string values by using the QueryString property of the HttpRequest object, as shown in the following example:

C#

String s = Request.QueryString["field1"];

Using Session State:
Information in session state is available to all ASP.NET Web Forms pages in the current application. However, session state takes server memory, and the information is stored until the session expires, which can be more overhead than you want for simply passing information to the next page.

To use session state to pass information
1. In the source page, save the information that you want to pass in session state, as shown in the following example:

C#

Session["field1"] = "value1";

2. In the target page, read the saved information from session state, as shown in the following example:

C#

string field1 = (string)(Session["field1"]);

Solution 3

One.aspx code-behind

C#

protected void Page_Load(object sender, EventArgs e)
{
    Response.Clear();
    Response.Write("Ths is the response from one.aspx: " + Request.Form["MyData"]);
    Response.End();
}

Two.aspx code-behind

C#

protected void Page_Load(object sender, EventArgs e)
{
    Response.Clear();
    Response.Write("Ths is the response from two.aspx: " + Request.Form["MyData"]);
    Response.End();
}

Default.aspx code-behind

C#

protected void Page_Load(object sender, EventArgs e)
{
    cmdSend.OnClientClick = string.Format("return sendData('{0}')", txtData.ClientID);
}

Default.aspx (needs reference to jQuery too)

ASP.NET

<asp:TextBox ID="txtData" runat="server" />
<asp:Button ID="cmdSend" Text="Send" runat="server" />
<div id="resulta"></div>
<div id="resultb"></div>
    
<script type="text/javascript">
    function sendData(txt)
    {
        var c = $("#" + txt);

        makeCall("<%=Page.ResolveUrl("~/one.aspx") %>", c.val(), $("#resulta"));
        makeCall("<%=Page.ResolveUrl("~/two.aspx") %>", c.val(), $("#resultb"));

        return false;
    }

    function makeCall(url, text, target)
    {
        $.ajax({
            type: "POST",
            url: url,
            data: { myData: text },
            contentType: "application/x-www-form-urlencoded; charset=UTF-8",
            dataType: "text",
            success: function (data) {
                target.html(data);
            }
        });

    }
</script>

I'm trying this solution but when its coming here
protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
Response.Write("Ths is the response from two.aspx: " + Request.Form["MyData"]);
Response.End();
}

to page one Request.Form["mydata"] the value out here becomes NULL....

F-ES Sitecore 22-Jan-16 3:44am

You're not supposed to navigate to those pages in the browser, the js calls the page via ajax and processes the results. Those pages will be whatever you currently have in one.aspx and two.aspx, you didn't say what those pages were or what they did or what they returned so I knocked up dummy versions that were the simplest I could do, just to get the example working.

Member 12277111 22-Jan-16 12:56pm

Sorry for that.. and thats my mistake.
practically I'm not navigating to that file, but they do indirectly get loaded to the page.....

I wish I could add images in here to show you how exactly they are linked up... Unfortunately I will try my best to explain Sitecore..

context.Response.ContentType = "application/octet-stream";
context.Response.TransmitFile(Server.MapPath(context.Request.QueryString["Download"].ToString()));
context.Response.End();
}

else
{

//Capture File From Post
HttpPostedFile file = context.Request.Files["fileToUpload"];
// HttpPostedFile file = context.Request.Files["Hiddenfilename"];

if (context.Request.Form["Opp"] == "uploading")
{

//Or just save it locally
file.SaveAs(Server.MapPath("Convert/input.pdf"));

file.SaveAs(Server.MapPath("Convert/output.pdf"));

context.Response.Write(ImageConverter());
