I hosted two asp.net web project in IIS with unique VirtualDirectory (sample and Sample2). Now i access a web page from Sample site and from this page i'm sending request to a web page in a site Sample2 with some values through Query String. I got the page and the values from query string.
Now my problem is, instead of sending values through QueryString is there is any other way to pass values from one site to another. Because, i never give the url for the second site to client. They know only the first site url based on user input i'll redirect it to the second site. Problem is user can see the values passed through QueryString and there is a chance to bookmark that link by user, it just like hacking. I donot want the user to do that.

In my website I have two forms: parent form and child form(dialog box). Their expected behaviour is like this: if clicked on 'show' button on parent form, a dialog form opens that displays a gridview. In dialog form, if clicked on 'select' button it closes
itself and returns value in selected row back to parent form.
To achieve this I write following code (.cs) : in parent form:
void ShowBtn_Click(object sender, EventArgs e)
{
StringBuilder jScript = new StringBuilder(); [code]....
Now problem is: the code in parent .cs works fine, it opens the dialog properly. But when clicked on 'select', instead of returning back to parent, it opens the same dialog again in new window. This newly open window says "Done but error on page" at left bottom.

I'm not sure the best place to ask this...not even sure the best way to ask it.
I manage a library website, and there are a number of different database products that can be searched. I'm trying to build a black box application to sit behind the home page. Here's an example of what might get submitted to said application.
searchType = "books"
searchEngine = "library catalog"
keywords = "some keywords"
See, the idea is that I might be doing various search boxes throughout the site, and I want to keep the actual HTML forms as simple as possible and simply let an ASP.Net application do the rest of the work. For example, figuring out whether or not the search engine using a GET or a POST method, parsing the keywords to determine the best way to render them, and sending the appropriate hidden values.
Probably, most of these databases use GET, so I can simply use a Response.Redirect after creating the query string, but I think some of them might use a POST, and I'm just not certain how I would take the form variables from one page (the home page, say), then essentially turn them into a virtual form on this middle man/black box application, and then programmatically submit that virtual form to another site, such that the user never sees or knows about that intermediate page.
I've seen this:
[URL]
But that isn't what I actually want to do, because I don't want to retrieve the result of the submission through a WebResponse...rather, I want the form to actually send the user to the new site.

Long time programmer just now getting into .NET so There may be something better but I would like to use the Graphics Server Extended Graph (Graphs32.ocx) on my form.
I tried to put it in the Toolbox by going to Tools --> Choose Toolbox Items --> Com Components tab
then check that item and press OK. From what I saw in help files, it should now appear in the Toolbox. Unfortunately, I can't find it anywhere. Did I miss a step in this process? I then tried adding the ocx to the project Bin folder and repeating the steps. Still can't see it. If I can't get it onto the Toolbox, is there another way I could put the control on the form ?

I was told to use a Repeater control in what I am doing which is a "Data Entry" screen with ASP.NET controls -a standard "address" like form. In cases, the fields on the form will repeated twice, once for the original values, one for the changed values. I have not used this control before but it seems like I have to bind to a database. Instead, I have an Entity object that has been obtained via a Repository. Can I bind to an object like this?
[DataContract()]
public class RON

I am using IIS 7 and have URL rewrite turned on for a friendly URL.
The problem is that in side that pages repeater (right under the captcha) when I click on the images in there the page redirects to /null/ which then throws a 404 error. I have turned off url rewrite and removed all rules and that didnt solve the problem so I dont think its related to that.
I have also noticed that in my master page if I use <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
then the client side ajax fails to load, sys becomes undefined and that may be the problem here
I'm at a loss, this is the first time I have seen these problems occur.

I have a calculator page that calculates the carbon footprint of electricity and water, which has two textboxes and two drop down lists and a button.
When a user enters a number in the two text boxes, each number is multiplied by the other number given in the dropdown list ,and then clciks on the submit button he/she gets the result in a label as well as the values he entered.
what I need to do is enable the user to add another calculation in the same form and i need the label to keep the result. so, the user can enter new values in the form as the fields will be cleared and clicks on the calculate buttin again, gets the result and the total result is added to the previouse one.

Apologies for the terribly newb question. We're currently implementing Google Web Optimizer in our ASP.NET Web Application and some of the code is supposed to go in very specific places on certain pages. For example, for the "Control Page" Google has some Javascript that sits outside of the <html> tags.
I know I probably don't need to place the code exactly where Google recommends, but we've been getting some goofy results lately, and I really wanted to make it as watertight as possible to ensure it's not just bad implementation. We have a lot of files in our project that reference the site.master, but only one needs to have some Javascript placed outside the <html> tag. This, in theory, seems simple enough, my question is this: Do I need to put a ContentPlaceHolder in every file that references the site.master? (Even the tens that aren't passing any code to the site.master?) That's not something I feel like doing for many different reasons (altering tens of files). If that's the case, and I do need to add empty ContectPlaceHolders to every page, is there some other way around things without having to piece together a unique file just to put some Javascript outside of the <html> tag?

Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file
So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.

Is it possible to add values from different database rows to a dropdownlist?
I'm currently trying to add both ItemSizeSmall and ItemSizeMedium, but through trial and error I can still only add one row from the database. I want the dropdownlist to display "Small" and "Medium" etc.
I guess my primary question is: How do I create a database with product size attributes?
I apologize if this thread should be in another forum, but if the dropdownlist can display two database rows I'll settle with that solution.
Could the database look like this:
table1: product
PK: productID
table2: productAttribute
PK: productID
PK: attributeValueID
table3: attributeValue
PK: attributeValueID
FK1: attributeNameID
table4: attribute
PK: attributeNameID
name
If this is right: How do I make the dropdownlist display the different sizes?

We have a large mvc2 project and just added an area to it. Now some of the paths in our forms are messed up. We are using Strongly Typed actionlinks and formextensions. Please look at the following demo: [URL] The form on this page is incorrectly submitting to the area. I think it's related to routing or just the way that area's are figured out when it's not specified.

I have a page with an asp:FormView. When I attempt an insert and it fails I loose the data in the form. ViewState is enabled.
<asp:FormView ID="frm_Person" runat="server" DataKeyNames="Person" DataSourceID="ds_edit_Person" DefaultMode="Insert" ViewStateMode="Enabled">
I am trapping the error on the datasource with
<asp:SqlDataSource ID="ds_edit_Person". oninserted="ds_Edit_Person_Sql_Event" onupdated="ds_Edit_Person_Sql_Event".
(ErrorHandler is just a static lookup function):
protected void ds_Edit_Person_Sql_Event(object sender, SqlDataSourceStatusEventArgs e) {
if (e.Exception != null) {
SqlException sqlex = (SqlException)e.Exception;
lbl_Error.Text = ErrorHandler.TranslateError(sqlex.Number);
e.ExceptionHandled = true;
}
else {
lbl_Error.Text = ErrorHandler.TranslateError(0);
gv_Person.DataBind();
}
}
How do I keep the values in the form?
