Asp – trigger updatepanel update using

asp.netupdatepanel

I have created a treeview using the following code in my code-behind.

<li><a href=../User/Category.aspx?CategoryID=ff62e353-6eb1-4215-8158-03767d2401de &  isRoot=true>Books</a></li>

When user clicks on Books,Category.aspx page opens and all products with this categoryID are loaded in a user control.

I want to trigger update to a updatepanel using this treeview node.Is this possible.

Please suggest some other way to achieve this.

Try this:

Script:

function UpdateAndRelocate(updatePanel, url)
{
    __doPostBack(updatePanel, '');
    window.location=url;
}

Markup:

<li>
    <a href="javascript:UpdateAndRelocate('../User/Category.aspx?CategoryID=ff62e353-6eb1-4215-8158-03767d2401deisRoot=true','UpdatePanel1'">Books</a>
</li>

According what I understand the textbox is embedded on User Control dtmDateFirstEntry. You CANNOT use directly a control contained by a user control. The user control MUST expose the events of his child controls if you want to use them as triggers.

<asp:UpdatePanel ID="upIntendedStay" runat="server" UpdateMode="Conditional">
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="dtmDateFirstEntry" EventName="DateChanged" />
    </Triggers>
    <ContentTemplate>
        <asp:Label ID="Label4" runat="server" Text="Update tHis text from server" CssClass="ErrorText"></asp:Label>
    </ContentTemplate>
</asp:UpdatePanel>

DateChanged would be an event exposed by dtmDateFirstEntry. Do you know how to do this?
