using System.Collections.Generic;
using System.Text;
using System.Web.SessionState;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ComponentModel;

namespace MyControls
{
public class TestForm : WebControl
{ HttpRequest Request = HttpContext.Current.Request;
HttpResponse Response = HttpContext.Current.Response;
HttpServerUtility Server = HttpContext.Current.Server;
HttpSessionState Session = HttpContext.Current.Session;

private TextBox mName;
private TextBox mCompanyName;
private TextBox mInfo;

protected override void OnLoad(EventArgs e)
{
  if (this.Page.IsPostBack)
  {
    this.EnsureChildControls();
    Response.Write(HttpContext.Current.Server.HtmlEncode(this.mName.Text));
  }  
}

}

protected void PrintForm()

  this.Controls.Add(new LiteralControl("Name: "));

  mName = new TextBox();
  mName.ID = "mName";

 hey my friend,

I think you lost the part that you need write some code to onclick of button like this: in last line add this code:

mBut.Click += new EventHandler(Button1_Click);
   

also you need to add this code

   void Button1_Click(object sender, EventArgs e)
    {
       // do whatever you want to do !
    } 

 

also I think you need to override render and in that just call the parent control Render

Hi,

<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p> </o:p>

From your description, it seems that you want to create a custom server control which handles Postback Data, right?

<o:p> </o:p>

If so, I suggest that you can try the following article which shows a tutorial on how to handle the postback data.
