pass multiple values from one aspx page to another

I have to pass values from one aspx page to another. The controls I
have in the first page are:
a textbox, 3 drop down lists, and 2 check boxes, and a submit button.
It is a search page, and the users need not enter values in all the
controls. they can leave the textbox blank, and select values from one
drop down, or any other combinations.
I am trying to pass values with the help of session variables. But I
have multiple if else statements like:
if (ddlCategories.SelectedItem.Value == "")
{
Session["CatID"] = "";
}
else
{
Session["CatID"] = ddlCategories.SelectedItem.Value;
}
The value in the second drop down depends on the value in the first,
and the value in the third drop down depends on the second drop down.
So, its giving me an error saying "Object reference not set to an
instance of the object" if I don't select any value from the first drop
down .(same is the case for the second drop down).
What is the best way yo do this? without all the if else statements,
and may be without using the session variables.
any suggestions?Regarding your object reference error...
You could check for the existance of a selected item first, before trying to
read its value, e.g.
Session["CatID"] = "";
if (ddlCategories.SelectedItem != null)
Session["CatID"] = ddlCategories.SelectedItem.Value;
However I think that there may be a shortcut approach using
ddlCategories.SelectedValue instead. I haven't tested this property without
a selected item, but it will probably return null rather than an exception.
Worth exploring. If it works for you, you may be able to simplify the
constructs to, e.g.;
Session["CatID"] = ddlCategories.SelectedItem.Value;
... with no safety check. If you need to treat "" and null the same (and
have "" as values in your list), you can write a helper function as in;
Session["CatID"] = MakeEmptyStringNull (ddlCategories.SelectedItem.Value);
Regarding your value-passing approach, session variables work fine but makes
the receiving page limited. I prefer to put essentially all navigation
rules into the Url so that users can bookmark search pages reliably, forward
the Url to friends, etc. The cleanest way I've found to do this is to
construct a class that manages the navigation to the target page, and
formulates the Url based on properties, e.g.
class SearchPageUrl
{
public string CatID;
public string Option1;
public string Option2;
/// Generate the Url
public override string ToString ()
{
return String.Format (
"/search/results.aspx?CatID={0}&Option1={1}&Option2={2}",
CatID, Option1, Option2
);
}
/// Determine whether the necessary properties have been set to generate
a valid Url
public bool IsValidUrl ()
{
return true;
}
}
in your onclick;
SearchPageUrl sup = new SearchPageUrl ();
sup.CatID = ddlCategories.SelectedValue;
sup.Option1 = ... ;
sup.Option2 = ... ;
if (sup.IsValidUrl())
Response.Redirect (sup.ToString ());
else
// show error
In your receiving page, you can simplify the querystring processing through
page-level properties, e.g.;
private bool HasCatID
{
get { return Request["CatID"] != null; }
}
private int CatID
{
get { return Int32.Parse (Request["CatID"]); }
}
Which keeps the code in your page clean, and centralizes the parsing of your
querystring propeties.
Clearly this is a bit more code than the Session var approach but it's worth
considering. Most users expect the pages to be bookmarkable.

Hi Macyp,
Checking that the SelectedIndex DropDownList property is not equal to
-1 before retrieving the SelectedItem.Value property should solve your
"Object referenct" problem. Sample:
if (ddlCategories.SelectedIndex != -1)

I have a web form that allows a user to do a search, they can select all the

a value to search on, how can I pass that to stored procedure and get data
back?
example form:
the user can search on

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 the values to the sub..

I am not sure how to pass the value to use another sub..

i want to pass these two value to another sub(passvalue ())..

Sub page_load(source as object, E as eventArgs)
strvalue1="value1"
strvalue2="value2"

passvalue()

end sub

sub passvalue()

xxxxxxxxx
end sub

Sub page_load(source as object, E as eventArgs)
 strvalue1="value1"
 strvalue2="value2"

end sub
sub passvalue(byval arg1 as string, byval arg2 as string, etc...)

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 values

Hi,
How to pass values from one to another page using post method? And how to retrieve them at another page?

ASP.NET uses by default POST method, so what is your question?

Regards

You can use a querystring through the URL, the session object, application object, Server.Transfer().

Depending on what you need, those are a few of the ways to maintain state off the top of my head.
In old asp 3.0. I'd use something like <form action="page2.asp"...>
Then In page two I'd use request to retrieve values.
How to achieve this with asp.net?

"In old asp 3.0. I'd use something like <form action="page2.asp"...>
Then In page two I'd use request to retrieve values."
In .Net you don't post do a different page, by default it post's back to itself. All web controls that have viewstate enabled will have their values stored during the postback and be accessable when the page post backs to itself.
Perhaps if you give us a specific example of what you're trying to accomplish it'd be a bit easier to help you specifically where you need it?
Lets say I want to have simple search funcionality. Search string whentyped in any page, should be passed to results.aspx page. There shouldexact searchs occur and results be displayed.
So...?

In c# code you should do something like this:

Response.Redirect("Results.aspx?searchString="+searchBox.Text+); //put a parameter in the redirect page

Note that the "searchString" is the name of the parameter you areadding to the redirect, you can call it whatever you want. ThesearchBox.Text is the TextBox of search.

Now in the page you've redirected, you will extract the parameter

string textSearch = Response.QueryString["searchString"];

Now that I'm here, how did you develop your search engine?Do you checkevery table in your database and return every values that match thesearch?If you have news, studies in your database you show for examplenews and then the news related, and then the studies and then therelated studies for example?

Thanks, hope I did help!

Hi,

If you have html page with search form, for example, you can add <form action="Result.aspx" type="post"> in it then you can get all post variables using Request.Form[variableName]. In case you use form as aspx page you do not need to transfer to other page - you can and should process all events (buttons clicks etc) right in this page. It's common for asp.net and it's recommend to use this technique.

But if you need to transfer post data to other aspx page you can use Server.Transfer() method in, for instance, button click event. Then you can get all post variables including controls state from previous aspx page using Request.Form.

In asp.net 2 you can also use cross page postback (read more about it therehttp://msdn2.microsoft.com/en-us/library/ms178139(vs.80).aspx).

I'm have the same problem. How can I get the Query String in VB?

do server.transfer.

Let me give you an example.

-- default page --<form runat="server"> ... <asp:textbox id="text1" runat="server" text="value1here"/> <asp:textbox id="text2" runat="server" text="value2here"/> ... <asp:button id="btn1" runat="server" text="button1"/> <asp:button id="btn2" runat="server" text="button2"/> ...</form>-- this is the btn1 onclick behavior you want to go page1.aspx right? --Protected Sub btn1_Click(ByVal senderAs Object,ByVal eAs System.EventArgs)Handles btn1.Click server.transfer("page1.aspx", true)end sub-- this is the way to show text1 at page1.aspx --Protected Sub Page_Load(ByVal senderAs Object,ByVal eAs System.EventArgs)Handles Me.Load label1.text = request.form("text1")end sub

that's it. you can pass the values within http request, because when you click buttons, the values gets saved to http request via postback. alll you are doing is passing values in http request in next page. form submission is done for you automatically.

improvise and you'll succeed.

Hope this helps and let me know what happens.

Jae.

Great but what if iis in a datalist? I can't get the value out.

you can declare a hidden field:

 <asp:DataList ID="datalist1" runat="Server"> <ItemTemplate> <asp:HiddenField ID="hidden" Value='<%#eval("valuetopass")%>'> </ItemTemplate> </asp:DataList>

user server.transfer afterwards then retrieve value by:

request.form("hidden")

Hope this helps.

Jae.

If you are using .NET 2.0, you can set the postBackURL on the form. This will allow your page to directly post to your new page.

Nick

Do you know how to do this in VB.net?

Sorry, I got it

Request.QueryString(

"Variable")

Thanks for the help.

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 between 2 asp.net applications

The 1st appn has a login page and the other appln has other pages.
When the user logs from 1st appln, i want to pass the username to be passed to the other application.
I do not want to pass through query string.
Is there other way out. Please help!!!!!!!!!

SaifIs there a reason why they are in seperate apps?

However, to solve the problem you could try using a Cookie.

You can get value from Url by using Request.Querystring["id"].
Thanks
Sharmila
You can use the QueryString property of the Request: Request.QueryString["id
"].

Pass values from one user control to a user control on a different aspx page

Hello,

I have an aspx page titled Search.aspx. Within this page, I have a user control titled Search.ascx. I want a user to input search terms, then on the click of a button, I want to pass the values to another page (SearchResults.aspx)...which will then display the results in a user control.

Can someone please give me some suggestions on how to do this?

Thanks a lot!Hello, what you can do is:

inside ur usercontrol, create a method that returns a dataset or datareader. that is, since u are searching using the usercontrol, then the result of ur search will be returned by a method of type either dataset or datareader.

and in ur code-behind of the aspx page u can use it as follows:

protected Myusercontrol user;
private DataSet ds = user.GetResults();

and then u might want to put it in a session variable or xml file and then u will be able to access it from the SearchResults.aspx

but why do u want to show results in another page ?

Pass Values to another page.

I am trying to a create a page that will query a SQLDB get customer
information and then pass this information on to another page creating
almost like a mail merge letter. I can get the information no problem using
a repeater but how do I pass <%#container.DataItem("Value1")%> to another
page.

Thx.Hi

Put information you want to share between pages either in
Session Object or Cache Object.

Pass values to .ascx

Hi,

Simple question really, how do i pass values to a .ascx file from .aspx file in c#?

ThanksYou can set property values from your ASPX code.

This site has ALL in the info you'll need, I just found it myself the other day.

Mastering Page-UserControl Communication
I tried this once with a page with a tabstrip + multipage setup. Each tab contained it's own ascx file.

I never got it to work the way I thought that it should. Check this newsgroup thread of mine to see if it applies to you:

http://msdn.microsoft.com/newsgroups/default.aspx?pg=35&lang=en&cr=US&guid=&sloc=en-us&dg=microsoft.public.dotnet.framework.aspnet.webcontrols&fltr=
I came accross the following code that solved my problem, might help others also.

in myuc.aspx
----------
<%-- declare any namespaces --%>
<%@. Register Tagprefix="Channel" Tagname="Title" src="http://pics.10026.com/?src=myuc.ascx"%>
<Channel:Title MyTitle="ABC" /
In myuc.ascx
----------
<script language="C#" runat="server">
public String MyTitle ="Not Set";
void Page_Load(Object Sender, EventArgs e)
{
if (Page.IsPostBack == false)
{
DisplayTitle.Text = MyTitle.ToString();
}
}
</Script>
<asp:Label id="DisplayTitle" runat="server" />

pass values of combo box to asp code

I have a combo box and i want to pass its values to open a connection.

To extract values from combo box my freind suggessted me to use Request.querystring("comboname")

but this could be used only when i pass values to the url.

is there any other way to extract the value from combo box

You are right Request.QueryString would be used when you want to get a value from URL. To use your combobox value use DropDownList1.SelectedItem.Text (to get a text) orDropDownList1.SelectedItem.Value (to get value).

Cheers
Ritesh

In addition to the above approach, if you are posting the form then the value of drop down list can be accessed by Request.form("NameofControl"), convert the values as per your requirement.
