How to display and get value in grid, where text has all special characters

[Nirav]

Hi,
I am using VS 2013, Telerik.Web.UI Version 2014.2.618.45, developing a website using UI for ASP.Net AJAX telerik Q2 2014 controls. 
I have radgrid and binding columns to radgrid. 

Now, the problem is while binding and retrieving value of column containing special characters. 
Lets say one of the column has value as "Test &nbsp; test <br /> test ' test " test <asp:Label  Test \n test \\n test". 
I made this value to test. I want to display this in grid and also, I need to fetch this in two events, ItemDataBound and ItemCommand.
I tried various methods like HTMLEncoding, replacing characters and also tried putting label control inside ItemTemplate but could not retrieve value as it is.

So what I am looking for is, 
To display and retrieve data value "Test &nbsp; test <br /> test ' test " test <asp:Label  Test \n test \\n test" and "Test line 1 \r\n test line 2 \r\n" which is stored using multiline textbox. 
1. Is it possible to handle both scenario together? like handle straight string and also handle multiline textbox value to display and retrieve as entered. 
2. How to display above value in grid perfectly as it is? Consider both the cases, first, its string as it is and second, possible that its stored using multiline textbox
3. How to display above value in telerik:GridBoundColumn and in <asp:Label control inside <telerik:GridTemplateColumn? 
4. How to retrieve above value from grid as it is, in ItemDataBound and ItemCommand events?

Thanks in advance,

Hello Nirav,

The issue that you are experiencing is a request validation feature of ASP.NET where, by default, the application is prevented from processing unencoded HTML content submitted to the server. Detailed information on this could be found at the following articles:

• Request Validation - Preventing Script Attacks 
• A potentially dangerous Request.Form value was detected from the client

Since this is not related to our controls in any way, you will need to manually handle (encode/decode) the input and output in such manner, so you could pass the request validation or you could just disable it, but please note that this could lead to security issues.

Hope this helps.

Thanks for the reply, 
No problem. I thought Telerik might have some ways to handle special characters.
Its an web form with textboxes to enter values, I will see if it is good idea to restrict certain characters.

Hello Nirav,

I forgot to mention that GridBoundColumns have HtmlEncode property (set to false by default), which specifies whether the text in the corresponding cell will be encoded automatically or not when displayed in the browser. However, this only applies to the cells and you will not be able to edit those values, but if you only need to display the special characters you could set the HtmlEncode property to true and see how it works.

Detailed information on the above is available in the following help article:

• RadGrid - Column Types

Hope this helps.
