+Summary: ASP.NET: State is not restored from ViewState for dynamically created controls
+
+Description of Problem:
+The state of controls that were dynamically created
+from Page_Load is not restored from ViewState.
+
+Steps to reproduce the problem:
+1. Run the aspx that I pasted in the
+ bottom of the description form field.
+2. Notice that the dropdown contains items.
+3. Click the button.
+4. Notice that the dropdown doesn't contain items anymore.
+
+Actual Results:
+State of dynamically created control is not restored
+from ViewState just after Page_Load.
+
+Expected Results:
+State of dynamically created control should be
+restored from ViewState just after Page_Load.
+
+How often does this happen?
+For as far as I know, always.
+
+Additional Information:
+I'm using Mono 0.26, release version, compiled with
+-d:NET_1_1 and I'm using the xsp 0.5 test web server.
+
+<%@ language="C#" %>
+<html>
+<script runat=server>
+ void Page_Load(object sender, EventArgs e)
+ {
+ DropDownList DropDown = new DropDownList();
+ DropDown.ID = "DynamicDropDown";
+ PlaceHolder1.Controls.Add(DropDown);
+
+ if(!IsPostBack)
+ {
+ // Populate the dropdown.
+ // We only do that 1 time, after that, the list
+will be
+ // repopulated just after Page_Load by the
+ViewState mechanism.
+ DropDown.Items.Add(new ListItem("Item 1"));
+ DropDown.Items.Add(new ListItem("Item 2"));
+ DropDown.Items.Add(new ListItem("Item 3"));
+ DropDown.Items.Add(new ListItem("Item 4"));
+ }
+ }
+
+</script>
