Ways to pass data between webforms

HC

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 the selected date from a calendar in a querystring - .net 2005 b2

We are trying to pass the selected date from a .net calendar in a
querystring. We manage to display the selected date from the calendar in a
Lable like this :

protected void Calendar1_SelectionChanged(object sender, EventArgs e)
{
lblDate.Text = Calendar1.SelectedDate.ToShortDateString();
}

<asp:Label ID="lblDate" runat="server"></asp:Label
What we are trying to accomplish is to pull the above value of the lable
which is "lblDate" to the following link and pass is as a querystring

<a href='default5.aspx?tech=<%# Eval("RESPONS")
%>&today=selected_date'><span style="font-size: 10px">Link
Name</span></a><br /
thnxprotected void Calendar1_SelectionChanged(object sender, EventArgs e)
{
lblDate.Text = Calendar1.SelectedDate.ToShortDateString();
litDate.Text = Calendar1.SelectedDate.ToShortDateString();

}

<asp:Label ID="lblDate" runat="server"></asp:Label>
<a href='default5.aspx?tech=<asp:Literal ID="litDate"
runat="server"/>amp;today=selected_date'><span style="font-size: 10px">Link
Name</span></a><br /
Or just use HyperLink WebControl and fill NavigateUrl property with correct
data.

Pass two values in querystring

I am trying to pass two values in a querystring. I have no problem passing one but when I try to pass two the second doesn't work.

Heres an example of what I'm doing:

Response.Redirect(passingpage.aspx&value={0}&value2=" & txtvalue2.Text)

The first value is from a hyperlink column of a datagrid which works fine by itself. When I try to pass the second value from a textbox, it doesn't work. I'm using visual basic.

Can anyone help?the first parameter is denoted by a ? and the subsequent ones a &

eg

http:www.costall.com/default.aspx?param1=hello&Param2=world

does this answer the question or is it a typo in the post?
I have tried that and it doesn't work. Any other suggestions?
can you post the code sample?
Hello, try this:

Dim url As String = "passingpage.aspx?value1=" & txtValue1.Text & "&value2=" & txtValue2.Text
Response.Redirect(url)

pass value to image control

This is my first time to use asp.net. I just want to get an image name passed from url (by using request.querystring), and then display this image, when user click the image, I also display the mouse coordinate. But I just can not get it to work, please help. Thanks. The following is my code:

<script runat="server">
Sub getCoordinates(sender As Object, e As ImageClickEventArgs)
 mess.Text="Coordinates: " & e.x & ", " & e.y
End Sub
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 Dim imagename as String = Request.QueryString("name")
 Dim imagePath as String =Server.MapPath("/keller/portrait/" & imagename)
End Sub
</script>
<html>
<body>
<form runat="server">
<p>Click on the image:</p>
<asp:Image
runat="server"
ImageUrl="<%=iamgePath%>"
OnClick="getCoordinates"/>
<p><asp:label id="mess" runat="server"/></p>
</form>
</body>
</html>

Welcome to the ASP.NET Forums, lily1.

The following update to your code will correctly show the image passed in with the QueryString.

<%@. page language="VB" debug="true" %>
<html>
<head>
<title>This is main Page</title>
<script runat="server"
Sub getCoordinates(sender As Object, e As ImageClickEventArgs)
 mess.Text="Coordinates: " & e.x & ", " & e.y
End Sub
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 Dim imagename as String = Request.QueryString("name")
 Dim imagePath As String = Server.MapPath("/keller/portrait/" & imagename & ".gif")
 MyImage.ImageUrl = imagePath
End Sub
</script>
<html>
<body>
 <form runat="server">
 <p>Click on the image:</p>
 <asp:Image runat="server"
 id="MyImage"
 OnClick="getCoordinates" />
 <p><asp:label id="mess" runat="server" /></p>
 </form>
</body>
</html>

The only difference is that I gave the asp:Image control an ID, and used this ID in your Page_Load code to set its ImageUrl property.

For details of how to get your imagemap working, see the following tutorial:
ImageMap.NET

I hope this helps.
Thanks for your help. I tried your script, The picture can be displayed correctly now, but when i click the picture, I got javascript error, it seems that function 'getCoordinates' does not execute at server instead it tries to run at client side. Here is url of the page:http://user1046822.wx15.registeredsite.com/keller/imagecrop_coodinates.aspx?name=test.jpg . Could you please tell me what is the problem? Thanks again.
> Could you please tell me what is the problem?

You've defined the problem yourself ... that getCoordinates tries to run at the client-side, not at the server.

Please go through the article I provided above. That will explain how to send click coordinates back to your server-side code.

You say you're "passing in a value" - Where are you passing it from? Where
are you passing it to?

You can pass values between pages using a variety of methods - session
variables are common, as is using viewstate. I prefer to structure my code
really well and use properties via the refernce page directive. Theres a
small example below for you

Pass values in QueryString using VB.Net

Response.Redirect("http://localhost/WebApplication3/Forms/paymentprocessing.aspx?fname=+"

'Me.txtFirstName.Text"'", False)

how do i pass the text from a control in the querey string???

Dim myURL as string = "http://Localhost/WebApplication3/Forms/paymentprocessing.aspx?fname="

myURL = myURL & Me.txtFirstName.Text

Response.Redirect(myURL, False)

passing a GUID in the querystring

I need to pass a GUID into a page via the QueryString. If I do:

Dim myGUID as GUID
GUID = Request.QueryString("myGUID")

It won't run, and says that a value type of string cannot be converted to a GUID. I can't retype myGUID as a string, because I use it in a SQL Server Database call...It yells at me if try to do a query with it in there.

Am I doing something wrong? or is there just no way to pass a GUID through the querystring?

ThanksIf you pass the value on the url it will be in a string format. The following worked for me. Maybe this will help.

select * from table1 where uniqueID = cast('{5BEEAA61-394B-44F6-9AC8-A6EA5FC99490}' as uniqueidentifier)
You need to do the following:

Dim MyGuid As Guid = New Guid(Request.QueryString("myGuid"))

Passing a javascript array to a handler .ashx

I am using a handler (processImage.ashx) to display an image. The image is
displayed according to parameters passed in the querystring. The handerl is
called via some clientside javascript.
I want to send an array of unknown length to the handler. I am not sure
whether the querystring is the best place to do this. What's the best way to
send an array held in the client side javascript to the handler?
Thanks in advance,
JJyou can not post an image request, so the url is the only option other than
a
prelimary ajax call. the url is restricted to about 2k. how you encode the
array depends on the array type. the most common is a array.join('|'), with
a
matching split on the server side.

Hi JJ,
I think Bruce means you should pass the image urls(or any array parameters)
either through url querystring or through AJAX xmlhttp request. Directly
manipulate binary content of image is not quite supported in client script
and also not effecient to pass such large content frequently.

passing a querystring

hey all,
i know i can do response.redirect("my.aspx?id=1")

but what if i'm doing a postback, is there something similar to querystring?

thanks,
rodcharHello,

Request.QueryString allows to read querystring parameters during a postback.
Is this what you are looking for ?

Use the viewstate collection or add a HiddenField.

passing ampersand(&) in querystring

I am trying to send a clients name to another page through a querystring, but some of their names are being cut in half where there is an amp.

 server.urlencode(Container.DataItem("Username"))

I even tried to use

Server.HtmlEncode

on the front and

.replace("&","^")

on the end, but I can't get it to work.
Does anyone know how to do this?
ThanksYou need to not have the ampersand in the querything unless before the parameter name. If you were doing soemthing like first&last, either send them as two words, or put a unique character that you can do a string.replace(character, newchar)
Thanks for the reply.
The problem is when there is a & as part of their name, such asA&B Painters
Also, not all company names have more than one word in them.

I think I used string.replace(character, newchar) as above, however it did nothing. Did I use it right? I think that is the way to go if I can get it to work.
Thanks
Just to make sure we have this straight, you are doing something like thisbefore you post it to the querystring:

Dim StringVar As String = "A&B Painters"

StringVar.Replace("&", "^")
Cool!
I will try that.
