Hi,
I need to add a 'WebDialog' component on to a webpage everytime a user clicks on a button.
This is the error I'm getting: Cannot unregister UpdatePanel with ID 'dialog0_Update Container' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.
Parameter name: updatePanel
I get the error here: PlaceHolder1.Co ntrols.Add(myDi alog);
Here is my code behind(c#):
public partial class MultipleWindows : System.Web.UI.P age
{
ArrayList arrayList;
protected void Page_Load(objec t sender, EventArgs e)
{
arrayList = (ArrayList)Sess ion["dialogs"];
if (arrayList == null)
{
arrayList = new ArrayList();
}
}
public void Button_OnClick( Object sender, System.EventArg s e)
{
//Create new web dialog
C1WebDialog dialog = new C1WebDialog();
dialog.ContentU rl = TextBox1.Text;
//Set the id
int len = arrayList.Count ;
dialog.ID = "dialog" + len;
//add it to the collection of Dialogs
arrayList.Add(d ialog);
Session["dialogs"] = arrayList;
//loop thru collection of dialogs and paint each one out
for(int index=0; index<arrayList .Count;index++)
{
C1WebDialog myDialog = (C1WebDialog)ar rayList[index];
// Add to the page's controls
PlaceHolder1.Co ntrols.Add(myDi alog);
// Set open dialog handler
HyperLink HyperLink1 = new HyperLink();
HyperLink1.Navi gateUrl = String.Format(" javascript:open Window($get(\"{ 0}\"));", myDialog.Client ID);
}
}
}
Here is page code:
<%@ Page Language="C#" AutoEventWireup ="true" CodeFile="Multi pleWindows.aspx .cs" Inherits="Multi pleWindows" %>
<%@ Register Assembly="C1.We b.C1WebDialog.2 " Namespace="C1.W eb.C1WebDialog" TagPrefix="c1d" %>
<html>
<head runat="server">
<script type="text/javascript">
var form_dialog;
function openWindow(dial og)
{
form_dialog = dialog.control;
dialog.control. show();
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptMana ger ID="ScriptManag er1" runat="server"> </asp:ScriptManag er>
<asp:PlaceHolde r ID="PlaceHolder 1" runat="server"> </asp:PlaceHolder >
<asp:TextBox ID="TextBox1" runat="server" Text="http://www.yahoo.com"> </asp:TextBox>&nb sp;
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button _OnClick"/>
</div>
</form>
</body>
</html>
Any ideas anyone?
Thanks
