I use TinyMCE in a DetailView in in EDIT MODE.

I would like to know if there is a solution which can prevent Request Validation to trigger an error

WITHOUT USING <%@ Page validateRequest="false" %> for my page.

The only way I found out at the moment is to encode TextBox used by TinyMCE using option: "xml"

tinyMCE.init({
        encoding: "xml",

In this way Request Validation does not trigger error but at the time to read the data in the TextBox the result it is Encoded. I also tried to Decode on PageLoad the content of the TextBox using this code

myTextBox.Text = HttpUtility.HtmlDecode(myTextBox.Text)

But the result is not as expected, so I can visualize it just Encoded text.

Any Ideas? Thanks

UPDATE

I found a solution to my problem. I added in _DataBound event for the DetailsView this code

       TextBox myContentAuthor = (TextBox)uxAuthorListDetailsView.FindControl("uxContentAuthorInput");
        myContentAuthor.Text = HttpUtility.HtmlDecode(myContentAuthor.Text);

So on DataBound event, (should work even on post back) the content will be decodene for textbox tinymce.

Here how should work:

01 - TinyMCE ESCAPE data inserted in textbox using function encoding: "xml",

02 - Data has been stored as ESCAPED

03 - To read the data and add its content to a TextBox where apply TinyMCE use in DATABOUND EVENT for DetailView and HttpUtility.HtmlDecode (so it will look decoded)

04 - You can modify content in the textbox in edit mode. On post back TinyMCE will encoded again using encoding: "xml" an so on

Hope guys can help some one else.

But please give me your comment on this solution thanks! Mybe you come up with more elegant solution! :-)
