Answer 2

You are not using a .NET control for your text area. Either add runat="server" to the HTML TextArea control or use a .NET control:

Try this:

<asp:TextBox id="TextArea1" TextMode="multiline" Columns="50" Rows="5" runat="server" />

Then reference it in your codebehind:

message.Body = TextArea1.Text;

Answer 3

You need to use runat="server" like this:

<textarea id="TextArea1" cols="20" rows="2" runat="server"></textarea>

You can use the runat=server attribute with any standard HTML element, and later use it from codebehind.

Answer 4

Missed property runat="server" or in code use Request.Params["TextArea1"]

Answer 5

First make sure you have the runat="server" attribute in your textarea tag like this

<textarea id="TextArea1" cols="20" rows="2" runat="server"></textarea>

Then you can access the content via:

string body = TextArea1.value;
