This is Default.aspx wit 1 manager and 1 zone:
<%@ Page Trace="true" Language="C#" CodeFile="Default.aspx.cs" Inherits="Default_aspx" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:WebPartManager ID="WebPartManager1" runat="server">
</asp:WebPartManager>
<asp:WebPartZone ID="WebPartZone1" runat="server">
</asp:WebPartZone>
</form>
</body>
</html>
This is the code file: In init() I create a WebPart.
public partial class Default_aspx : System.Web.UI.Page
{
public Default_aspx()
{
Load += new EventHandler(Page_Load);
}
void Page_Load(object sender, EventArgs e)
{
}
protected override void OnInit(EventArgs e)
{
if (WebPartZone1.WebParts.Count == 0)
{
MyWebPart control = new MyWebPart();
control.MyValue = "kaan";
control.ID = "id";
control.Title = "kaan";
WebPartManager1.AddWebPart(control, WebPartZone1, 0);
}
}
}
and this is the webpart:
public class MyWebPart : WebPart
{
private string _myValue;
public string MyValue
{
get
{
return this._myValue;
}
set
{
this._myValue = value;
}
}
protected override void OnUnload(EventArgs e)
{
Context.Response.Write(this.MyValue);
}
protected override void Render(HtmlTextWriter writer)
{
writer.Write("dfgsdfgsdfgdfgsdfg");
}
}
If I run this code, I find 3 WebParts on the page. Although I set the MyValue in Default.aspx.cs, in OnUnLoad() it is empty!!
