Hi,

I have created a user control with 2 panels: the first panel has a form with a 'next' button that toggles the visibility of the panels; only one panel is visible at a time. On the second panel, I have a form with 3 buttons: Save, Add New and Delete.

Basically, the user can enter and save details of mulitple items, e.g. title and description. I am using ViewState to store the list of items.

Item myItem = new Item(itemId, txtTitle.Text, txtDesc.Text);
List<Item> items = (List<Item>)ViewState["Items"];
items.Add(myItem);
ViewState["Items"] = items;


When the user hits the Save button, it dynamically creates an Edit link for the item and displays the Edit link with the title in a list below the form and clears the form.

E.g:

link_edit = new LinkButton();
link_edit.Text = "Edit";
link_edit.PostBackUrl = "/umbraco/page_name.aspx?id=" + itemId;

 Expected output:

Edit  Description of my first item
Edit  Description of my second item
Edit  Description of my third item

When the user hits the Edit link it loads the title and description back into the form, allowing the user to Delete or Edit the details and Save.

I set postbackurls for the Save and Delete buttons to ""/umbraco/page_name.aspx?" to remove the querystrings on postback. 

Now.. I have created and tested this user control with c# in Visual Studio and it works perfectly. When I created a macro from this user control and inserted it into a page, the postbackurls and viewstate don't work :(

Getting past the first panel is OK; panelOne is hidden and panelTwo is visible. If I enter an item and description, then hit Save, postback appears to reload the page as though for the first time. The eventhandler for the buttons aren't firing (I put in debug statements).

I am hoping someone can shed some light because I'm stumped! Hopefully I've given enough information about what I've done and what I'm trying to achieve...I am running Umbraco 4.5.2, IIS 7 and Windows 7.

Thanks in advance
