HI Gianluca

It will probably be a bit easier to help you out with the code if we can see a snippet of it. :-)

If you have written the onClick event by hand it's possible that there is a typo in it for instance...but I asume that you have used the design view en visual studio and double clicked the button to get the code written for you automatically. So maybe it's the code inside of it that's the problem?

Post a snippet then it will be more easy to help you out.

Hello again!

@Jan: here is the code of my custom server control... thanks for your help!

Cheers, gianluca.

    public class MyPurchaseForm : WebControl, IPostBackDataHandler
{
       public override ControlCollection Controls
       {
       get
            {
                EnsureChildControls();
                return base.Controls;
            }
        }
        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);


            customerCode .ID = this.UniqueID + "_customercode";
            customerCode .Attributes.Add("style", "margin: 5px 0 0 18px; width: 180px;");


            btnLogin .ID = this.UniqueID + "_login";
            btnLogin.Text = "Accedi";
            btnLogin.Attributes.Add("style", "margin:4px 0 0 10px; display:inline-block; color:#000");
            btnLogin.Click += new EventHandler(btnLogin_Click);
        }


        #region IPostBackDataHandler Members
        public bool LoadPostData(string postDataKey, System.Collections.Specialized.NameValueCollection postCollection)
        {
            customerCode .Text = postCollection[this.UniqueID + "_customercode"];           
            return false;
        }


        public void RaisePostDataChangedEvent()
        {
            throw new NotImplementedException();
        }


        #endregion


        protected override void OnPreRender(EventArgs e)
        {
            if (Page != null)
                Page.RegisterRequiresPostBack(this);


            base.OnPreRender(e);
        }


        protected override void RenderContents(HtmlTextWriter output)
        {
                      output.WriteLine("<label style=\"margin:20px 350px 0 18px; width:auto; text-align:left;\">My message</label>");
                      customerCode.RenderControl(output);
                    btnLogin.RenderControl(output);
                    break;
            }
        }
        void btnLogin_Click(object sender, EventArgs e)

            DoSomething();
        }


        private void DoSomething()

Hi,

I think the macro needs to be enclosed in a <form ruant="server"> tag for it to work.  Or did you already try that?

Hi Tom,

Yes, of course. I did not mention it, but of course I have created a Macro that invokes my Custom Server Control. The macro is used inside a Master Page, which provides the <form> tag, inside which it is rendered the custom control and it is loaded the Macro by using <umbraco:Macro alias="..." runat="server" />.

Perhaps my question is more generic, perhaps my ideas regarding custom server controls are not that clear... 

My objective is to create a custom server control that collects some info from the user, keeps them in mem until the last step is reached and finally persists the information (writes to a db).

I look forward to receiving your opinions, 

Cheers,

Gianluca.
