In essence, I am creating Dynamic Checkboxlist controls and adding them to a Panel. It works well when I do not have a Master Page configure to this webpage. Once I have a masterpage congifured.. I get a "Object Reference not set to instance of object" error on the Panel_Control.Controls.Add(Checkboxlistnew) line:
protected void Page_PreInit(object sender, EventArgs e)
XML OXML = new XML();
alistChkBoxLabels = OXML.XMLTransform("C:\\Documents and Settings\..\\Config_new.xml", "config_options/check_box/applications/app/@name");
int count = 1;
alistCheckisFacility = new ArrayList();
alIDTracker = new ArrayList();
while (count <= alistChkBoxLabels.Count)
Checkboxlistnew = new CheckBoxList();
Checkboxlistnew.ID = count.ToString();
Checkboxlistnew.Items.Add(new ListItem(alistChkBoxLabels[count - 1].ToString(), alistChkBoxLabels[count - 1].ToString()));
String sAppName = alistChkBoxLabels[count - 1].ToString().Trim();
alistCheckisFacility = OXML.XMLTransform("C:\\Documents and Settings\\Administrator\\My Documents\\Visual Studio 2005\\WebSites\\User_Trial\\Config_new
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
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! :)

Hi everybody. Heres the deal. I have a three step Wizard with various textboxes in it. I out the Wizard inside an Update Panel and Content Template. I launch the site and the first step of the wizard is executed nicely but when I click next to get to the second step, nothing happen. If I take the wizard out of the update panel then it works fine.
Any help would be very much appreciated cause I am a bit new in ASP.NET.
Thanx a lot.
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
If ctrl.HasControls Then
I can't get my <ajax:asyncfileupload> working and I don't see why...
Here's the error:

document.getElementById("<%= lblStatus.ClientID %>").innerText = args.get_fileName(), "<span style='color:red;'>" + args.get_errorMes
I hope someone here can shed some light on this one...
We have a document library configured with a few content types and document information panels for those items. Also on this list we have a BDC column setup to pull client names from MS CRM. This works fine on the list itself, however, in Word 2007 - the picker does not show up in the DIP, so we cannot easily select clients without knowing the name (first issue).Secondly, if we enter in a client name, or partial, we recieve the following error:"There was an error in the validation code" - with the following details:Document Information Panel cannot complete this action, because of an error in the form's code.The following error occurred:Object requiredFilecript.jsLine:171Any help is appreciated!
I have a sharepoint list[Managers] with groupby sector column. like below
Each Sector group by column data i want to display in label or panel control.
How to do that ? how to write the logic?
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)
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
