Pass multiple parameters into pages querystring property from jscript

This is a basic question but I cant seem to find the answer anywhere and
have never tried it before.

Here's one of many syntax I'm trying, but should at least show you what I'm
trying to do:

parent.data.frameElement.src="data.aspx?Task=CartAddNew & sku=" + ItemSku;

where there's 2 parameters, Task and sku, and I'm trying to pass a text
value of "CartAddNew" to the Task parameter and a value from the ItemSku
variable to the sku parameter.

Thanks.

moondaddy@dotnet.itags.org.nospam.comI found the answer in another posting when I searched on "Pass"

The correct way to separate the 2 parameters and their value assignments is
with a & and no spaces on each side. I had tried it with a space on each
side which made it fail. Here's what worked for me:

parent.data.frameElement.src="data.aspx?Task=CartAddNew&sku=" + sku;

refer to my post below for clarification on the value assignments.

pass several parameters

Hello,

I am new with asp.net and I have some basic questions:

1What's the normal way of passing several server objets )(asp:text...)values to another page, when I click in a submit button.
(the same that we were doing in asp with the post.

2.I have a page where I have to do a search of the data of a peron by Id.
When the user click in the search button after givint the id, dO I have to bind each server control (in this case 5 <asp: testbox..>, name, surname, address, age, date birth) to the result of the query to retrieve the data?
How do I do that if my result is in a only query?

ThanksSee if below Link coule helps you. Seems you also have to do same kind of business ligic.

Pass Value from Code Behind to TextBox

Hi, I have a very basic question (I am a beginner)

How do I pass a value from the Code Behind to, say, a text box?

I've got this on my aspx page:

<asp:TextBoxID="TextBox1"runat="server"Text=strTestOnTextChanged="TextBox1_TextChanged"></asp:TextBox>

All I want to do is pass the value of strTest from the Code Behind to display in the Text Box. This is what I have in the code behind:

using System;

using System.Data;

using System.Configuration;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

publicpartialclass_Default : System.Web.UI.Page

{

protectedvoid Page_Load(object sender,EventArgs e)

{

String strText;strText ="Hello";

}

}

How can I get this to work?

It's very simple just try this

protectedvoid Page_Load(object sender,EventArgs e)

{

String strText;strText ="Hello";

TextBox1.Text =strText;

}

You are right...it is very simple;

Thanks for the help...and Iapologize for the very basic question;

don't forget to mark as answerd the post if it is.

Whenever you write something in PageLoad event, it should be executed with every postback event... So use IsPostBack event of page to identify page was post back or not ...

passing a string to a confirmation page

Hi folks -- newbie Dave here.

I have a page where a user enters some basic info (name, email address, etc.), then they click Submit.

I then display a confirmation page. I want to display text that says something like "Thanks Dave, we got your info".

In the info form page, I'm doing this when Submit is clicked:

Sub ConfirmMsg()
Dim name As String
name = txName.Text
Response.Redirect("free_cvi_confirm.aspx?name")
End Sub

Here is the Page_Load function on the confirmation page:

Private Sub Page_Load(ByVal .....)
Label1.Text = "Thanks " + Request.QueryString("name") + ", we got your info"
End Sub

This displays nothing when Label1 displays. And when I look in Request.QueryString, I also can't find the name value.

What am I doing wrong? I've tried a few different variations, but can't seem to hit it. Thanks in advance for your great help.

DaveHello, in the page where u submit the form the conform message page should be like this:

Protected Sub ConfirmMsg(ByVal sender As Object, ByVal e As EventArgs)
 Dim name As String = String.Empty
 name = txName.Text
 Response.Redirect("free_cvi_confirm.aspx?name=" + name)
End Sub

In the second page:

Protected Sub Page_Load(ByVal src As Object, ByVal e As EventArgs)
 Label1.Text = "Thanks " + Request.QueryString("name").ToString() + ", we got your info"
End Sub

Good Luck.
HI davehunt,

Welcome the asp.net forums...

Use this

Response.Redirect("free_cvi_confirm.aspx?name=" & name)

thatz it
I believe that the 2 methods suggested so far place the values of the variables in the querystring (and then retrieve the values from the querystring). If having the variables visible in the querystring is acceptable, then I don't see any reason not to use those methods.

However, if you want to "post" the variables instead use this...

In the first page:
<script runat="server">
Sub Submit(Sender as Object, e as EventArgs)
Server.Transfer("http://path/page2.aspx")
End Sub
</script>
<html>
<body>
<form runat="server">
<asp:TextBox ID="tbName" Runat="server" />
<br>
<asp:Button Text="Submit" Runat="server" OnClick="Submit" />
</form>
</body>
</html
In the second page:
<script runat="server">
Sub Page_Load(Sender as Object, e as EventArgs)
lblName.Text = Request.Form("tbName")
End Sub
</script>
<html>
<body>
<form runat="server">
Name =
<asp:Label id="lblName" Runat="server" />
</form>
</body>
</html
Hope this helps,
Rob
Thanks guys, this was a big help.

Passing A Value To Server

Basic Web Form... A few text boxes and a checkbox - and a card reader...
The effect I want to accomplish is this:
The basic credit card fields are there and can be filled out. But if the
user swipes the card, I want to fill out the fields automatically and make
them read only. (So far I can do this.)
But I also want a checkbox to appear that indicates the card was swiped.
The user can clear the checkbox, re-enabling the fields so they can be
edited, but then I will no longer consider the data as being swiped. I want
the check box to disappear if they clear it.
Using server controls, if I create a checkbox, but make it not visible, then
it's not available at the client side to work with from client side code.
So I would need to send some flag back to the server to indicate a post back
and have the page re-rendered properly. But how do send info to the server
like that without having a visible control to attach the data to?
(Does this make any sense? Not sure if I'm explaining it well.)
Is there a way to send a value back to the server, in a postback, where the
data is not a property of a server control that's tracking viewstate? The
session object is only available on the server side right?
Any guidance here is appreciated. Thanks.
Jerryto send additional value to server , one commonly used method is
a HiddenControl (you will access it like Request.Forms["HiddenContrlName"]
from code behind)
or a TextBox Webcontrol with size 0 or attribute style='display:none' ..
But if the only purpose of post back is to display/check the checkbox ,
probabaly a better approach is to do the display/check in the client side
javascript ..
Instead of settign Visibility=False, you would just add an attribute to
make it hidden , but still available at client code
CheckBoxName.Attributes.Add("style='display:none'")

Okay... I can have the checkbox on the form and available with 'Display:
None'...
But I can't seem to find the proper syntax to change the display state and
make it visible on the client side...

Obviously there is some thing not right other than the syntax.. :) .. Is
there any javascript error when you call the function to display the

Once this works, you can compare with the HTML your aspx generated and that

if still no luck, you may want to create a simple HTML page with only
following code in it...

<INPUT TYPE=checkbox ID=chk1 style='display:hidden'>
<INPUT TYPE=button ID=btn1 onClick="toggle()" value="Click to Toggle
Display"
<script>
function toggle(id)
{
el = document.getElementById("chk1");
var display = el.style.display ? '' : 'none';
el.style.display = display;
}
</script
Once this works, you can compare with the HTML your aspx generated and that
may help in finding the issue..
