Question

On Page_Init, if is post back, I check if a button called Button1 was clicked, if so I add a LiteralControl to a Panel called Panel1:

Panel1.Controls.Add(new LiteralControl("Enter Code:<input type=\"text\" name=\"txtCode\"></td>"));  

As you can see, it is just the text “Enter Code:” followed by a TextBox called txtCode.

I have a second button (Button2) that, when clicked, I would like to retrieve the text entered in txtCode:

protected void Button2_Click(object sender, EventArgs e)
    {
        foreach (Control c in Panel1.Controls)
        {
            if (c is LiteralControl) ...                
        }
    }

I’m not sure how to do this… How can I get the text entered in txtCode?

Answer 1

You can always use the Request.Form collection:

string txtCode = Request.Form["txtCode"];

It will contain all values posted with the current request, regardless of being server side controls or not.
