Kindly review this link

You can set data in code behind by using ViewData and can access them in html as explained in above link.

couldn't you just save the value to a variable in your codebehind file and then on the webform itself just reference the variable by some manner such as <%= varName =>??

The above seem like a lot of work just to reference a variable that you can set quite easily in C# and then pull in the page load.

I guess your trying to accomplish is to populate your textbox with the variable on the server side with out runat="server" set to the control.

You can do that with ajax and simple jquery.

Lets say your have this on your YourPage.aspx

<input id="txtMyTextBox" type="text" />

and next is a simple jquery

function getMytextValue() {
        $.ajax({
            url: "/MainPage.aspx/YourServerSideFunction",
            type: "post",
            data: "{ }",
            dataType: "json",
            contentType: "application/json;charset=utf-8",
            success: function (data) {
                //Get your value from JSON data.d;
                $('#txtMyTextBox').val(data.d);
            },
            error: function (request, status, err) {
                //Do something here for error;
            }
        });
    }

And now just call the jquery on what ever event you like.

PS: dont forget to create a [WebMethod] on your code behind.

Hope this help you! :D

An ASP.NET TextBox control with the TextMode property set to MultiLine will generate an Html TEXTAREA control.

So instead of crafting Html TEXTAREA manually, you can just drop a TextBox control and have:

 <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine"></asp:TextBox>

and then in your code behind:

 TextBox2.Text = "... blah blah blah...";
