Web Forms :: How To Handle Html Inputs In The TextBox
Feb 20, 2010
I have a requirement that user can input HTML tags in the ASP.NET TextBox. The value of the textbox will be saved in the database and then we need to show it
on some other page what he had entered. SO to do so I set the ValidateRequest="false" on the Page directive. Now the problem is that when user input somthing like :
Now its values saved in the database, but when I am showing its value in some other page It redirects me to "http://www.xyz.com" which is obvious
as the javascript catches it. But I need to find a solution as I need to show exactly what he had entered. I am thinking of Server.HtmlEncode. Can you guide me to a direction for my requirement
I've written a 'register' aspx page and it works fine. Except, while testing it, if I start typing a name in the textbox, and a name with the same 1st letter already has been typed in there before, it keeps showing of and I would like it not to. Its like the autocomplet option of a combobox in winforms VB.
to turn of this feature so no one can see what a previous user has typed in the textboxes?
I have a HTML.BeginForm() to change user's data (email, password etc) but I want to separate the contents at the same page, I mean that there will be:
MainContent with submit button and also - a HTML.BeginForm() with fields to change password + submit button - a HTML.BeginForm() with fields to change email + submit button
the thing is, I want to allow user to change his password without sending all form data to the controller, only data from the password fields.That View inherits from my buisness object with properties (Login, Password, Email etc)
I just need to write the string in one textbox from another one.But the problem that i felt is that what kind of event handing i need to include for textbox.Simply,when user type the particular string on textbox and when h/she pressed the tab button,then this string should automatically be displayed in another textbox within same webpage.
My question is better tricky,i know how to handle enter key event in single for textbox in master page. but in my case, i have a text box and button for do the seach and another login user control to do the login.
Then i have write code for trigger the enter key event to every textbox focus. but alwys search button click event is raising. even if focus the login control text box focus.
I am converting the entered values in textbox into decimal values to saev in sql table. In case user does not enter any value i get a Format exception. How do i handle this..
I want to give people the option of entering multiple email addresses in a multiline textbox or textarea that are separated by commas. how to get the list into an array, then validate each email address, then process each email.

But it gets saved in some HTML format in Database as follows.
[code]....
So, Is there any ways that I can show this in Text box as what I need. While debugging the code, when I did HTML Visulaliser, it showed me correct format. How can I achive this in my Textbox control.
I am working on a project in ASP.Net MVC3 and this model of development is quite new to me, but I think I am starting to get the hang of it.
In my project, I am creating a dynamic array of <input type="check"... Checkboxes. From my understanding, when sending form data it should be processed in the Controller using <form method="post"....
So my question is: what is the best way to go about consuming a dynamic amount of HTML objects sent in the post data? What I am doing right now is looping through all the controls sent VIA: post and parsing the dynamic ones by the ID name. This method seems highly suspect in terms of coding practice. It does work, but I am wondering what the "norm" is for this sort of proceedure?
I'm setting up a radiobuttonlist where registrants to my site will be telling me how they found out about my site. What is the best way to store those answers in an MS SQL database?
Should I embed the radiobuttonlist in a control that I could then "connect" to my database (should I use DetailsView? FormView? I'm assuming not GridView or ListView---because I only want to display one record at time?)
Or should I not use an ASP.NET control---and just write a script in VB that binds this control to my database (even though I'm only just learning VB, and would prefer to use ASP.NET controls as much as possible).
Again, all I want to execute is a simple way to display options with corresponding radio buttons---and then store the results for each individual user into the SQL record that corresponds to the user's UserId.
I am validator controls to validate all of the my inout controls.
My requirement is i need to validate all of the inputs before saving and updating. I have no problem in that because by default all of the input conrols are validating based on the validation rule.
I have the Copu flag option in dropdown, when i am in the the Copy option i dont need to validate some of the input controls or dont need to validate all of the input controls when i clicked Save or Update button.
I have a textbox which I need to enter html code into (like < strong> or < em> for example).The trouble is this is causing an error writing this back to the database. A potentially dangerous Request.Form value was detected from the client (tbVOther="< strong>testIs there a way around this without turning off the request validation setting?
I have a comment form inside the blog posts. in the form, if the user is authenticated, I will assign the values of the user into textboxes. that part is as follows;
[Code]....
But when I add HTML.TextBox instead of HTML.TextBoxFor, I am not getting validation if the user erase the fileds. Also, this form is inside the indext page and it is related to another action as follows;
[Code]....
so I cannot assign ModelState.AddModelError from controller.
I am trying to update the database with the edited data. However, it did not manage to read the edited data from the textbox. It returned the retrieve data that I have done in the Page_Load instead. Is there any part of the code that I have written wrongly? I did manage not to use <EditItemTemplate> in my past project and manage to update the database with the same logic.

I am trying to find a way to limit the inputs on a webpage to a variety of different sequences, and although I have worked through the regular expression library, I am still confused on how to allow decimal places and a maximum value. I initially used rangevalidators, but as you know, these only limit the inputs to a range, and have no control over the decimal places entered. A variety of limits i have been asked to implement are:
1. Range 0-45, 0 decimal places 2. Range 0-20, 2 decimal places 3. Range 16-65, 0 decimal places 4. Range 0-99, 2 decimal places 5. Range 0-1500000, 0 decimal places 6 Range 0-200, 1 decimal place
For 1 and 5 respectively, I have used ([0-9]|[0-9]d|45)$ ([0-9]|[0-9]d|1500000)$
but want to be sure that I have understood the pattern correctly. How do I then go about creating a pattern for the other examples?
need to add textbox in gridview and write code in textchange event in asp.net..i show the data in gridview if i click the button i show the textboxes but i need to write the code in that textchange event in that
If I add this to the ASPX page: <input id="Text1" type="text" value="Text1Value" /> I would expect to see "Text1" in the list of Request Form keys even WITHOUT setting the runat=Server property. request.Form.AllKeys I realize that if I do set that propery, then I will have a server-sided HTML control that I can reference using the name "Text1," but shouldn't I be able to access the text in the text box using the following VB.NET syntax? request.Form("Text1")
I know that I can htmlencode and decode server side with ASP.Net, but i've run into an issue if I want to work with some of my forms that should allow html tags when working out side of my companies network. The issue is with my companies firewall tests for cross site scripting attacks. So, now I need to encode/decode my text on the client side it would seem. What does the rest of the world use and/or do to overcome issues like this?
