Treeview problems in Update panel



I tried using this code, on a Treeview inside an update panel, which is populated dynamically in code behind. 

However, it doesnt give me the required functionality.

Following is my aspx code for the TreeView and the TreeView populating logic:


<div id="treelist">
<asp:UpdatePanel ID="UpdatePanel1&quo

Accordion Control with Panel...Add an Update Panel?


I have an accordion control in my web site.  And in one of the panels, I have a drop down list box where, when the user selects an item, it updates the labels right below the ddlistbox.  I have it so that it maintains the scroll position when the ddlistbox has an autopostback, but it's very obvious that the whole page posts back.

My question is, can I/should I just enclose the ddlistbox and the labels (and a couple of text boxes) in an AJAX update panel?  I already have a ToolScriptManager (because of the accordion control), so I don't need to have another script manager, right?  I can just put the update panel (with the other controls inside of it) right in the accordion panel, right?  Then when the ddlistbox posts back it won't have the delay of the whole page posting back?  And it'll still execute the event handler for the listbox selection change?

Does this sound right?  I'm just looking to make the post back "invisible", and I would like to do a partial postback of just these few controls.

Thanks in advance! :)

Trying to set update panel trigger programmatically


 I have a recursive sub that finds a dropdown list and sets up an AsyncPostbackTrigger for an update panel. I have tried calling this sub both from page_init and page_load 

If the dropdownlist is within the update panel, eveything works fine. If the dropdown list is not in the updatepanel I get error

A control with ID 'ddlPersonFilter' could not be found for the trigger in UpdatePanel 'up1'. In both cases the sub does find the dropdown list and executes the code to set up the trigger. Thanks for your help.

    Private Sub SetUpdatePanelTrigger(ByVal oControl As Control)
        For Each ctrl As Control In oControl.Controls
            If TypeOf ctrl Is DropDownList Then
                If CType(ctrl, DropDownList).ID = "ddlPersonFilter" Then
                    Dim thisddl As New DropDownList
                    Dim thistrigger As New AsyncPostBackTrigger
                    thisddl = ctrl
                    thistrigger.EventName = "SelectedIndexChanged"
                    thistrigger.ControlID = thisddl.ID
                    Exit Sub
                End If
                If ctrl.HasControls Then
                End If
            End If

Problem with master page and update panel (I think)



the app I am working with is made up of three nested master pages that have the following design:

The first master page ha only realize the HEADER, BODY and FOOTER divs.

The second one specialize the Body content placeholder and divide it in three more layers: NAVIGATOR, PAGE TITLE, BODY CONTENT.

The final layer specialize the BODY CONTENT in PAGE CONTENT and ACTIONS.

In one of my content pages I have (inside the PAGE CONTENT area) 

  • 1 Update Panel that contains a gridview object
  • 1 Update Panel that contains some HTML code to show in a PopupModalExtender

The PopupModalExtender can be either triggered from inside the gridView and also from a series of LinkButtons that are in the ACTIONS area.

The problem is that when the PopupModalExtender shows the FOOTER and the ACTIONS areas are not dimmed from the style I apply as background to the modal popup. An example of what I am trying to explain can be viewed in the following screenshot.

Why this is going to happen? Has anybody any suggestion on how to solve this problem?

Thanks a lot

Update Panel only doing full postback

I have a page with a TabContainer with 3 tabs.  Within each tab, I have an UpdatePanel.  One of my UpdatePanel's update mode is set to "conditional" and I've added an asyncpostbacktrigger with the controlId="btnClearEmail1" and the eventname="Click".  When I run the page and click the button assigned to the asyncpostback trigger, the page will do a full postback.  Am I forgetting something?  How can I get it to just refresh what is inside the UpdatePanel?  <asp:tabcontainer id="ajaxTabContainer" runat="server"> <asp:tabpanel id="ajaxTabCustomerInfo" runat="server" headertext="Customer Information" visible="true"> <contenttemplate> ...
