State Management :: Secure Query String Or Session Variable

Aug 30, 2010

Example scenario:
User login has a list of associated 'accounts' it has access to... this list of accounts is stored in a database table, say tblAccountAccessControl, something like:

login, accountID
userA, account123
userA, account456
userA, account798
userB, accountABC
userB, accountDEF

This info is used throughout the web application and determines the 'domain' of information the particular login has access to. For example there are many other tables that have the 'accountID' field and whenever a page pulls data from the table it only pulls data that the currently logged in user should be allowed to see, based on that tblAccountAccessControl data.

The security question:
Do I need to query the database every time I need to get this list of allowed accountID's? I was about to use a plain old query string to pass a particular accountID to another page but quickly caught myself as I realized that would be a major security flaw (the receiving page was going to use that accountID to grab info from the database, and there would be nothing preventing a user from simply typing in a url manually to get data from an accountID they are not supposed to be allowed to view). So I then thought I'll just store the list of accountID's in a session state variable so they will be carried with the user throughout the session.

But then I remembered there are tools out there that allow you to easily intercept and modify asp.net viewstate information and I'm not sure if that would included session state variables, but I'm guessing they would. Is there a way to create a secure query string? If I used session state would that session state information be exposed and modifyable by utilities out there? Am I just stuck having to query the database every time I need this info to assure security? What about encrypting it and then storing in session state variable (just thought of that one)?

Web Forms :: Trying To Pass A String Variable As A Parameter To The Document.getElementByID Function

Jan 17, 2011

I have a label "lbl1" that I am trying to locate in a content page from the Master page. I want to do it dynamically so I am trying to pass the name of the control (which in this case is lbl1) through as a parameter. I don't get an error, it just doesn't work. If I do an alert to see what the string "temp" looks like, it is correct, but iit seems as if Javascript ignores it. I believe it has something to do with the '<%= not being interpreted correctly by the browser&nbsp; I'm sure it is a simple solution, but I can't figure it out!

I have a page with some datasources in it. I am doing reenginering of the page itself and would like to split some parts of the page in several user controls. In my code I have an ObjectDataSource object with the following params

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
<asp:ControlParameter Name="albumID" ControlID="txtAlbumID" Type="Int32"/>

This piece of code automatically bind the hidden field "txtAlbumId" to the datasource. In my revision this datasource should be moved to a user control. What is the best way to handle a scenario like this?

C# - Cannot Pass A Input From Text Box To A Query String And Then Keep The String In This Box?

May 28, 2010

I have a simple ASP.net page:

<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>

I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.

That's the code behind page:

protected void Page_Load(object sender, EventArgs e)
input_box.Text = Request.QueryString["input"];
protected void run(object sender, EventArgs e)
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);

Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?

Forms Data Controls :: Use A Query String Variable Created On The Fly To Populate A Child Webpage?

Feb 22, 2010

I have developed the below web page which has an asp.net 3.5 listview control as it's frontend and an sql server db as it's backend.


The first row on the web page is the inserting row. What I am hoping to achieve is that when the user enters their appropriate data they click the "Next" button to assign this dataset with it's own identity ID (customer_id) value within my database (this works perfectly), at the same time on the fly I want to use this customer_id as a query string variable to populate a child page (customerTrades.aspx) in order to pin further data to this identity. Currently I am attempting to use the below code within the iteminserted event of my listview control but I receive the error: "object reference not set to the instance of an object"??

protected void lvTrustAccounts_ItemInserted(object sender,
ListViewInsertedEventArgs e)
string customerID = e.Values["customer_id"].ToString();
+ customerID + "");

Is this because the child page cannot find the customer_id variable being passed through the query string? Because it's not actually created yet? Am I using the wrong listview event? How can I achieve what I am looking for?

I must also mention that I'm using a linqdatasource to insert my data on runtime into my database. However, I am using the listview iteminserting event to insert my frontend dropdownlist selected values, code below:

protected void lvTrustAccounts_ItemInserting(object sender,
ListViewInsertEventArgs e)
= DateTime.Now;
= null;
DropDownList ddl_CountyInsert =
DropDownList ddl_CityInsert =
DropDownList ddl_CountryInsert =
= ddl_CountyInsert.SelectedValue;
= ddl_CityInsert.SelectedValue;
= ddl_CountryInsert.SelectedValue;

I searched on this all morning, but I'm still not sure. If I create a session variable to pass some data between a couple of pages, does that variable time out after it reaches the timeout period set on IIS, or will it persist for the entire time the user keeps a session alive? For example, session variable is used shortly after login and then never again. Susy uses other pages for two hours and keeps session active. Did that first session variable die after 20 minutes, or is it still there 2 hours later?
