I have this following setup, a textarea named with some data in it that may have carriage returns and another textarea that has style='display:none' in order to make it hidden as follows:
<textarea id="myTextarea" onBlur="encryptMyData()">
I have a tablecell where I import the text from a SQL database and this all works well, except that the carriage returns are not being displayed in the text.
I have done some googling and although I do not get any error messages, the carriage returns are not appearing in my table cell.
Here is the code:
[Code]....
I have also tried Environment.NewLine, etc. but all to no avail.
I've got a text box on my page called txtNotes - multiline textbox.
When I add the text into the sql server database, the line feeds are not getting entered.
I have a function that replaces the line feeds with "<br>" and it's still all in one line. Also I don't see the normal square type entity after each line in the database, that is normally there for a line feed.
However, when I copy from the database and paste it to Notepad, it is formatted correctly

I have an ASP.NET multiline textbox. I can hit return to create carriage returns on the screen but the text property of the textbox is ignoring the carriage returns and simply concatenating the lines without even a space in between. I am writing this text property to a database and I want to be able to retrieve the text exactly as it was typed with carriage returns included.
View 2 RepliesI'm new to .net, and I've noticed that when viewing my HTML source code generated by a .net application the carriage returns are removed from the head tag when it has runat="server" attribute on it.
I remove the runat="server" and the returns... return.
This really looks nasty when you have a few javascript and css files in your header because it ends up making the entire contents of the head tag 1 big line.
Just wondering if there's a way to control this or tell .net through configuration not to mangle the output?
I have an some code to export data form an SQL database to an Excel spread sheet. the data is entered via a web site and some of it contains multiple lines of information. I need to preserve the multiple lines but excel 2007 continues to put an [?] at the end of each line.Here's what I got so far
CellValue.ToString() // this returns [?][?] at the end of each line for excel 2007
// and a single [?] in excel 2010
CellValue.Replace("[//r]","") // this works correctly for 2010 but still leaves a [?] for 2007
Cellvalue.Replace(Environment.NewLine, "") // this removes all the line breaks.
what can I replace the Environment.NewLine with in order to still have line breaks in both excel 2007 and 2010 (with no [?]) ?
I have tried a number of ways to format the text of a label with codebhind, I don't get errors, but it just ignores the code.
For example, if I put label.text = "Some text " & chr(13) & "some more text"
it will just ignore the chr(13). I have tride vbcrlf, /n, etc.
I would rather not have to change the control to a text box but will if I have to.

I have a webApplication in which i want to encrypt the data using Public key and whan it reach to the destination webapplication it will decrypted there with corresponding private key . Is there is any way to creating this pair of key?
View 3 RepliesI have some data I want to encrypt in an ASP.NET MVC application to prevent users from tampering with it. I can use the Cryptography classes to do the actual encryption/decryption, no problem there. The main problem is figuring out where to store the encryption key and managing changes to it.
Since ASP.NET already maintains a machineKey for various things (ViewData encryption, etc), I was wondering if there were any ASP.NET functions which let me encrypt/decrypt my own data using the machineKey? This way I would not have to devise my own key management system.
I have a problem hopefully someone out there will steer me in the right direction.
I have a web application that I am going to put on a standalone cd - currently the data is "Safe" because the database is in in the app folder and the code is located in the codebehind.
My problem is i'm putting this on a CD as a standalone site, anyone can access the database, or find the XML....
Is there a way to generate an encrypted Database / XML Page, that is complied with the CD, that the program can decrypt and access with a embedded key?

how to Retain data in a dataTable upon postbacks in a web application as we can retain the data in a datatable in a windows application.
View 2 RepliesI am having an aspnet panel in my aspx file.There is an ultraweb tab placed inside this.also I am having a button outside this panel.Within the tab I have a textbox whose readonly property is
set to "true".Whenever I click the button a javascript function is called .On clicking 'OK' in the popup ,the textbox values are lost.Is there a way to retain these values?
I have recently started learning ASP.NET with MVC 2 Framework, I am facing difficulties in the following scenarios.In my MVC application I want to retain partial information in Model over post backs.Following is my scenario,
1. I initiate "Edit" of main record by clicking date hyperlink from left navigation.
2. Amend some data.
3. Save the record.
4. "Edit" sub record of the saved record by clicking another hyperlink from bottom left navigation panel.
The page is divided in to 6 tabs, the first 5 tabs shows the data for the main record and the 6th tab shows data of sub record. Wehn we "Edit@ sub record the previous 5 tabs doesn't have any changes noted, that means there is no harm in keeping their details intact in the main model. So is there a way to access model in the controller on hyper link click action so that I can only load the data for the clicked sub record (I am asking this, because the hyperlink click uses HTTP GET method so no model parameter passed in action method). If no, then how do I retain partial values in the Model over post backs?
Note that each tab data have been kept in individual models, and a main model has a collection member to hold all these individual models together.I thought as the model is binded with the view, it is too binded with controller. But it is allowing easily to access model in variable "Model" for the view but not for the controller.
I have the example working but I added a Select Command to the Detail grid for the purpose of selecting a detail record which will redirect to another page. The problem is that when the Select command is clicked the expanded detail grid collapses as if I had clicked the minus. The page and codebehind are:

View 8 RepliesI am having a gridview with dropdownlist and textbox controls.
I am generating a value in the textbox2 depending on the textbox1 value using the javascript in every row of gridview. In onblur() function of textbox2, I am disabling the textbox2.
Before textboxes, I am having dropdownlist's in every row of gridview. when I disable the textbox2 in the first row and select the value of dropdownlist in the second row, the value of textbox2 in first row is not visible.
I tried by using the viewstate but I am unable to retain the value.
I have a formview tied to a gridview. The formview shows the data for the row selected in the gridview. The formview is invisible by default , default mode is readonly and becomes visible only on Selecting a row in the gridview. I make it visible in the SelectedIndexchanged event of the gridview. There are Insert and update buttons present outside the formview which perform the insert and update using code-behind. The code is below.
AFter an insert or update, the formview makes invisible again. I want to show the formview with the newly inserted or updated row in Read-only mode. How do I do this?
