[2008] masterpage contentpage updatepanels

[jconway]

VS 2008, vb.net .net 3.5 sp1.
I have a simple masterpage that formats the basic website. A scriptmanager, a timer a updatepanel and one content panel.

I also have a form that is a web content form based off the masterpage.

In the content I have a updatepanel that contains a number of components.

Here is the issue, whenever the timer trigger fires for the masterpage it is also causing an update which fires the Pageload() on the content page which has undesirable affects. How can I force the content page updatepanel to not fire the callback on the content page yet still update the masterpage?

Masterpage Scriptmanager properties

<asp:ScriptManager ID="ScriptManager1" runat="server" 

AsyncPostBackTimeout="120" AllowCustomErrorsRedirect="False">

</asp:ScriptManager>

Masterpage updatepanel properties.

<div id="footer">

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<table class="style2">

<tr>

<td class="style3">

<asp:Label ID="lblTime" runat="server" CssClass="footertext"></asp:Label>

<asp:Timer ID="Timer1" runat="server">

</asp:Timer>

</td>

<td align="center">

<asp:Label ID="lblmanagedby" runat="server" CssClass="footertext" Width="368px"></asp:Label>

</td>

</tr>

</table>

</ContentTemplate>

<Triggers>

<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />

</Triggers>

</asp:UpdatePanel>

the updatepanel is in the footer Div of the masterpage which contains the timer, a textbox and on the page load I do the following

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

lblTime.Text = thetime()

Dim uid As String = HttpContext.Current.User.Identity.Name

Dim managedtxt As StringBuilder

managedtxt = New StringBuilder("Site managed by Citrix managed Services")

managedtxt.Append(ControlChars.NewLine)

managedtxt.Append("Welcome: ")

managedtxt.Append(uid)

managedtxt.Append(ControlChars.NewLine)

managedtxt.Append("mailto:[email protected]")

lblmanagedby.Text = managedtxt.ToString

End Sub

Protected Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles Timer1.Tick

lblTime.Text = thetime()

End Sub

Protected Function thetime() As String

Dim currenttime As Date = Date.Now

Dim stringtime As String = currenttime.ToString("g")

Return stringtime

End Function

Content form Updatepanel config

<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">

<ContentTemplate>

..... lot's o UI components

</ContentTemplate>

<Triggers>

<asp:AsyncPostBackTrigger ControlID="btnEdit" EventName="Click" />

<asp:AsyncPostBackTrigger ControlID="btnNew" EventName="Click" />

<asp:AsyncPostBackTrigger ControlID="btnSave" EventName="Click" />

<asp:AsyncPostBackTrigger ControlID="btnCancel" EventName="Click" />

<asp:AsyncPostBackTrigger ControlID="btnServers" EventName="Click" />

</Triggers>

</asp:UpdatePanel>

Do a check in the Page:

If Not ScriptManager1.IsAsyncPostBack Then
 
'your code
End If
