How to read HTML5 textarea's text with vb.net code at the back

Question

I am trying to read the HTML5 Textarea's (not ASP.NET textbox control) text and pass it to my aspx.vb code at the back of the web page. How can I do it?

If can't, can I use JavaScript or other language pass the value to my back end vb code?

<textarea name="content"id="textarea" cols="90" rows="20"runat="server">
</textarea>

What have you tried? Knowing more about the structure of your page and how it is communicating with the server will help to answer your question. Please read[How do I ask a good question?](http://stackoverflow.com/help/how-to-ask). — Jason Aller, Mar 14 '14 at 18:05

on .aspx page, html text area -

<textarea runat="server" name="exampleTextArea" id="exampleTextArea"></textarea>

on .vb code behind page, you can get the value by calling this -

Me.exampleTextArea.Value

FULL EXAMPLE TO CALL THIS VALUE -

Dim textAreaValue as String = Me.exampleTextArea.Value

Someone else wrote something about this (in c# but You can convert using some online converter). Here is link : Get textarea in codebehind

Of course, You can use TextBox and set TextMode="Multiline"... but If You won't then link above.

Html5 textarea its just a misunderstand, but,anyway, set attribut name to your textarea, then if your textarea are in a runat server form, in the code behind, in the page load event you can easily test if request["textareaName"] exist and if exist you can read the value directly from Request
