Hi,

I've created a web user control that have a FileUpload and a Button, and did put this control inside an UpdatePanel then register it like :

ScriptManager.RegisterPostBackControl(Document1)

and it worked OK. But the problem is that if I put another instance of my control and register them like:

ScriptManager.RegisterPostBackControl(Document1)

ScriptManager.RegisterPostBackControl(Document2)

The second instance (Document2) works fine but Not the first one (Document1) and for that I'm assuming that only the second Document did get registered.

I've tried this solution in the folowing link and it didn't work:

So, how can register more then one control?

Thanks

badis

Hi,

We can register more controls which exist in Updatepanel to trigger for a full postback by using ScriptManager.RegisterPostBackControl Method (http://msdn.microsoft.com/en-us/library/system.web.ui.scriptmanager.registerpostbackcontrol.aspx).

For example, there are three buttons in Updatepanel and we will register two of them to fire full post back:

<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
        Label1.Text = "Label inside Updatepanel " + DateTime.Now.ToString();
        Label2.Text = "Label outside Updatepanel " + DateTime.Now.ToString();

        ScriptManager1.RegisterPostBackControl(Button1);
        ScriptManager1.RegisterPostBackControl(Button2);
    }
</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:scriptmanager ID="ScriptManager1" runat="server">
        </asp:scriptmanager>
    
    </div>
        <asp:updatepanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
            <contenttemplate>
                <asp:label ID="Label1" runat="server" Text="Label"></asp:label>
                <asp:button ID="Button1" runat="server" Text="Button1 is registered" />
                <asp:button ID="Button2" runat="server" Text="Button2 is registered" />
                <asp:button ID="Button3" runat="server" Text="Button3 is NOT registered" />
            </contenttemplate>
        </asp:updatepanel>
        <asp:label ID="Label2" runat="server" Text="Label"></asp:label>
    </form>
</body>
</html>

If you want to set trigger for Updatepanel, please see http://www.asp.net/AJAX/Documentation/Live/mref/P_System_Web_UI_UpdatePanel_Triggers.aspx

I look forward to receiving your test results.
