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

Problem with User Control, Update panel and flicker

Back button and update panel problem



I have a search page that uses an AJAX update panel to deliver results to the user. They can then navigate to a product page for more info. So far so good...

My problem occurs when they are on a product page and use the back button. They are redirected to the search page, but its a blank search page and not the one they left when they clicked for product details. I realise this is because the browser only made a history 'marker' (I dont know the technical term) when they first came to the search page, so this is what it returns them to.

Does anyone know how I can make the back button redirect the user to the search page as it was when they left it? I have tried making the page expire immediately and storing the search terms in session state so I can rebuild the page when they click 'back'. This works in IE, but not in Firefox as it seems to just load out the old page from the cache regardless of the expiration policy I set. As if that werent bad enough, this also causes 'corrupted state information' error when they try to search again.

Any suggestions? Any help would be very much appreciated.

Thank you

(PS -  I have seen various solutions to the back button/ajax problem, but none of them seem to address my problem. Or have I missed something?)


Update panel problem in gridview footer


On my aspx page, I'm having troubles when I have an update panel within the footer template of a gridview. It appears to be an intermitent problem that occurs on subsequent postback when you do a delete command in the gridview. The first delete command always goes through fine (first postback). Clicking on another row to delete on the gridview (or any other button on the form) triggers this error:

An error has occurred because a control with id 'ctl00$SupremeContent$grdLineNumbers$ctl09$ctl00' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error.

If you click the back button in the browser, then click on another page, then come back to this page, you can delete another record. Another attempt to delete another record brings you back to the above problem. Thectl00$SupremeContent$grdLineNumbers$ctl09$ctl00 changes each time you delete, come back to the page and delete.

If I disable the udpate panel, there's no errors.

The reason I have the update panel is so that the user can select the relevant pipe specification (they see multiple columns using a textbox, drop down extender, panel and gridview) without the form's data being reset by the embedded gridview's

Modal Popup Extender and an Update Panel - "Cancel" Button problem


This should be a quick "yes" answer - I am in the process of creating a very simple test, but I thought I'd ask on here too (also, so other people might be able to find the answer, if they have the same problem).

I have created a modalpopupextender that opens up a panel containing an update panel.  I have a cancel button that is tied into the MPE's [CancelControlID] property and this closes the popup when I click it.  However, if I perform a partial postback within the update panel, the cancel button no longer works.  I have found an example online that seems to imply that the cancel button (and I'm guessing, by association) and the OK button should be outside the update panel.  Does the partial postback break the buttons' client script bindings, and thus should they always be placed outside the update panel?

Update Panel Problem



on button click event i called server side code(enable page contorls) and then call javascript function using following code

protected void btnNewPayments_Click(object sender, EventArgs e)

protected void btnNewPayments_Click(object sender, EventArgs e)



ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "key", "return EnableDisable(true,false)", true);

Treeview problems in Update panel

<div id="treelist">

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
