Security :: Displaying Html Received Via Post?

May 17, 2010

I created a page that receives an html report from post data. This html is split up into pages and displayed in divs (as well as used to create a .pdf file but I don't think that is a security risk if the displaying it isnt a risk).

My concern is that I had to set ValidateRequest="false" in order to be able to do this. If the page somehow received malicious input with a serverside script or something, would the script run / could this be dangerous?

This is how I'm handling the request: I have a div with runat="server." Then, in the page_load event (i'm using vb.net codebehind) i set the div.innerHTML property to a modified version of the html received via post.

Css - ValidationSummary Style Not Displaying In IE 6 On Post?

Nov 16, 2010

I am posting back to the server to check the DB to see if we hold a reference number. If the reference number does not exist I set two custom validators to invalid and change the ValidationSummary header text. The problem is that the background colour I set in the css class does not display. The font colour does display correctly.

When the validation summary is displayed using client side script the styles are displayed correctly. i am not sure why they dont when there is a post back.

css
.form-box .form-error-box {
background: #cd3300 url("../../../images/alert.gif") no-repeat 10px 10px;
color: #ffffff;
font-weight:bold;
padding:10px;
padding-left: 80px;
min-height:55px;
}

code

<asp:validationsummary id="vSummary" cssclass="form-error-box" displaymode="BulletList" headertext="An error has occured" runat="server" backcolor="" forecolor="" />

This works in Firefox and IE 8 on post but not IE 6. Unfortunatly I have to support IE 6

Web Forms :: PayPal Post / Users To Buy More Than One Item And Displaying?

Jan 3, 2011

I need some help to finish of my PayPal page.

I am using Visual Basic in ASP.NET. I have been able to send items to PayPal, complete the transaction and then come back to my site. I have the been able to send and receive the token & auth code, and also the Payers details. (See code Below)

What I need help with is displaying the items that have been bought. If the user buys only one product then that is fine as I can just hard code for one item. BUT I want users to buy more than one item and displaying it has caused a problem.

I know that PayPal sends all the data back for the items, with the result being item_namex, quantityx, mc_gross_x. Where x is the item number.

This is where I have the problem. Do I hard code for item_name1,2,3,4,5...... 100 (which is alot of code) or is there a better, easier way to extract ALL items and display in a simple table.

At the bottom of my code you will see my first attempt at the table (highlighted by ****************)

Getting Value Of HTML Select Element On Form Post?

Mar 29, 2010

I have a View that has a select drop-down list and an edit button within a form. What I want to do is have the user select one of the options from the select element, click on the edit button, and get the value of the selected option in the Controller method.

I created my form with <% Html.BeginForm(): %>

and the Controller "Edit" method should be called.

I looked through several online examples, but each one focused on how to set values and the default selected value of the select element, rather than retrieving it from the code in the Controller method. I tried grabbing it from the Request.Form collection like:

string val = Request.Form["myDropDownList"].ToString();
and also:
string val = Request.Form["myDropDownList"];

Obviously I didn't do this correctly, because I get a null reference exception. Does anyone have the solution to this issue?

MVC :: Form Post Not Working With HTML Inside A Textarea?

For some reason I can't get an ajax post action to work if the text inside an textarea contains HTML. In the text area I am entering <h1>test</h1>, when I do that, I can click on the Save button all day if I want, nothing happens. Not sure whats causing this, but it also appears to do it if I don't use the ajax form and just a standard html form.

Jquery - Allow User To POST Html String To A HttpHandler?

Feb 11, 2011

I am writing a content management system using JQuery.ajax & C#. The JQuery calls an httpHandler and POSTS the html from an html editor JQuery plugin.

I get an error in the handler about unsafe content (html basically) but I dont want turn off validation for the whole page, just the handler (the handler is part of a web control not the page).

So, is it possible to turn the validation off just for one handler? Or do I need to encode the html on the client?

In the end I went for the encoding on the client at Javascript/JQuery HTML Encoding

Javascript - Displaying <textarea> Value As HTML?

I have a form with several textarea elements. User enters data and submits the form. On the next page it shows submitted text as static text - in p tags. Obviously New Line and multiple paces get ignored and everything just shows in one line. I can do some preprocessing like replacing New line characters with "br/" and spaces with . but I was wondering if there is a standard solution to that either on server side (C#) or client side (javascript)

VS 2010 - Displaying Comments In Inner HTML

Feb 20, 2012

I have to display some HTML from our system and do by using

DivOutline.InnerHtml = outlinetext;

where outlinetext is a string of HTML

However the string contains code as below

"<!--[if !supportLists]-->"

which for some reason also gets displayed.

I think it could be because the actual string is

("<!--[

but even when I try

outlinetext.Replace("<", "<");

the text does not seem to get replaced

How to make the comments not display or why the string.replace function cannot pict out "<" when I can see it is definately in the string?

MVC :: Html Helper Data Grid - Sorting Columns Using Post?

Jul 22, 2010

I've been asked to take over a project that's filled with a bunch of bugs. It's currently using MVC 1.0 and there's a view with Html Helper Data Grid that uses a DataGridHelper class. I'm not that familiar with all of MVC yet, and I was wondering if it is possible to have the sorting of the columns be a POST event rather than a GET.

Currently when a user clicks a column to sort, the controller for the view calls the GET action method. This I guess is all fine and good, but the problem is that this view has a search form (which is a model in it's own right) with some text boxes and some drop down lists. When the GET action method is called, I lose all of the information in the search criteria. So when ever someone searches for something, but then wants to sort the results, it requries the db for all records (because all of the search criteria is cleared).

I guess there could be two solutions:

1) Is there a way to access the items in the search form / model in the GET portion of the action method? I've tried using ViewData or adding a parameter for the search form model, but (and maybe I'm doing it wrong) both return null.

2) Is there a way to make the sorting event of a column call the POST portion of the action method? That way I'll have the search form / model information and be able to sort the search result content instead of query for all records.

Also, there is a stored procedure that currently can handel all of possible search parameters. So, no matter what sort column is selected, or search parameters are entered, it can properly setup the sql query.
