.net - ASP.Net 3.5 AjaxControlToolkit CollapsiblePanelExpander In Master In UpdatePanel Partial Postback Woes?
Aug 8, 2011
I have a content page linked to a master page. The master has the toolkitscriptmanager. On the content page, I have a nested repeater within the item template of the parent repeater, I have a CollapsiblePanelExtender for the child repeater control. Upon partial postback, if the collapsed attribute is not set, then all of the panels expand. If the collapsed attribute is set to true, then all of the panels are collapsed upon partial postback.
The databinding of the repeater is occurring in the page_init section of the code behind, and I am checking the state of the panels by iterating through the items in the page_load event. Nothing appears to be working, while debugging the code, I do see the properties being appropriately set, but when rendered in the browser, all panels are open. The edit event that triggers the partial postback is preformed in a modalpopup.
I have attempted to move the panels into their own update panel, remove the update panel, place the modal outside of the update panel to no avail. The ViewState is not maintained.
Page Code:
<asp:Repeater ID="rptrConsultants" runat="server" OnItemCommand="rptrConsultants_ItemCommand" OnItemDataBound="rptrConsultants_ItemDataBound">
<HeaderTemplate>

I'm having few UpdatePanels on my master page. And then, I have RadTreeViewcontrol on the page, that should cause partial postback each time node is clicked. Everything works fine there.
Since I'm using the same tree on some other pages, I moved this functionality to UserControl. Stuff I've done before, so no problem. Moved some code to ascx, created some events. Everything always worked for me well. But not now.
RadTreeView is nested inside UserControl, and this control on master page with update panels, see below:
<asp:Panel ID="pnlContentWrapper" runat="server" CssClass="ContentWrapper">
<div id="HeaderBreadCrumb">
<asp:ContentPlaceHolder ID="HeaderBreadCrumbContent" runat="server" />
[Code]...
What I don't know is: why is this causing full postback instead of partial? I suspect that it may have something to do with raising my for SelectedNodeChange, but I don't know how to deal with it other way. I need to let other components know, that node selection changed. How can I improve this to make it work with UpdatePanels?

I have a situation where I want to evaluate a record to make sure it fits a specific set of criteria. If it fits the criteria, raise an alert message for confirmation from the user. I do not want to raise the popup unless the criteria matches.

I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
Sample Code:
<asp:Timer ID="Timer1" OnTick="Timer1_Tick" runat="server" Interval="10000"></asp:Timer>
<asp:updatepanel id="upParent" runat="server" UpdateMode="Conditional">

It seems like a lot of people are having trouble with this piece of the control toolkit.I've looked for a few days on the internet for an answer and haven't been able to find one. Best solution I've seen so far is "write your own reordering procedure" which I don't want to do.
<asp:ScriptManager ID="smgrJobBidding" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="uPanelReorderList" runat="server"

I have an AsynchFileUpload on my page and for some reason when I try to use it to save the file to the server it falls. The control will allow me to select a file locally and it displays the local file path in its text box, BUT when I then click a button on my page which I am going to be using to submit all details then upload the page everything goes wrong and I get a Null Ref Exception from the AsynchFileUploader.

It seems that the filename is being lost somewhere after the button is clicked, or just never stored

I have extended an Entity Framework 4 entity class with a calculated property in a partial class. This member is not available on the client to which the entities are exposed via WCF RIA Services.when using C# appears to be changing the extension of the partial class file from .cs to .shared.cs. I tried this with my VB.Net solution (.vb to .shared.vb) and got a long list of errors. I believe what happened is that the partial class lost its association with the entity on the client - it inherited from object rather than EntityObject.
My best guess is that this is related to the way that VB.Net handles namespaces.Each project has a 'Root Namespace' which is prepended to anything that is defined within a code file. C# has a 'Default Namespace'which is the namespace into which new types are placed by default - via a namespace statement within the file.The partial class is probably having the client namespace prepended to it which puts it into a different namespace than the entity with which it is associated on the server.Is there any means of extending an entity in such a way that those extensions are available on the client via WCF RIA Services and VB.Net?

I'm using VB2008 Express and I'm using the ListView control for the first time. My problem is that I'm trying to add an item to the listview on one form (frmMain) to another (frmItems) but it's not doing it. I'm using subroutines and have discovered that it seems that the command has to come from within the form the listview is contained itself. But even if i have the subroutine in the same form, it doesn't work if i call it from the 2nd form.

i have a list that has things that needs to be looped. This list can be up to 500k items.I would like to add a multithreading option with a variable. This is not an issue, as I know how to make multiple bgw's (Code below)
i = spin_NumOfThreads.Value
Dim bgwrks(i) As System.ComponentModel.BackgroundWorker
For Each bgworker As System.ComponentModel.BackgroundWorker In bgwrks[code]....
so in that code, it'll make the number of threads based off of my spineditor.Now, ideally i'd like it to go through a list, each thread does its thing.Now, a simple dowork would just allow it to do 1. i would ideally like it to stay @ X threads until the list is done, so how would I basically go about remaking a thread once it finishes to continue? So, lets say I have 50 items in a list, i set the number of threads to 5.The first 5 would do the first 5 items, when the 1st one finishes, it works on item 6, then the next would do 7, etc. and it'd keep remaking until 50 is done.

This is probably a really easy question but i cant seem to find an answer anywhere.I've got a datagrid in which the first 2 columns are comboboxes.I have them populating from 2 different datasets but what i need is for the second one to be filtered, depending on what is selected in the first.How is the best way to pass the selected value from the first combo to the query in the second?On a related note, how can i set the combos to values i pull back from a query?Basically I'm running a query to pull back a load of information that has been previously entered and then populate the grid so that it can be viewed/amended, but i cant seem to set the value (or the display value) to what i pull back, even when it appears in the list of options in the drop down.

i have a form app that needs to get the output of a console app in real time.or as close to it as possible.[code]that is my code so far, and it seems to work great for everything other than the actual console app i need it to.when i use it on ping commands it comes up in my text box perfectly.when i use it with my console app (which i don't have access to the source for) it outputs nothing until the app closes, sometimes.it depends on the arguments given. i am 100% sure it is the way the app is written but there is nothing i can do about it.so is there any way to get the desired functionality some other way?

I'm trying to figure out how to get mixed-language support working in Visual Studio 2008. In my app_code folder, I've created two subfolders (CS, VB), and added the following to the web.config file:
[Code]...
The main application is a VB.NET Web application (with a .vbproj file). Any time I attempt to open a C# file from the app_codecs folder, it treats the file as Visual Basic for compilation and syntax checking purposes. It still tries to build the classes in the CS folder as though they were Visual Basic. (The extension on these classes is, indeed, .cs.)

I have an AppBar application that I've added a few drop down menu items and context menus to, but each and every time I try to access the menus, they appear outside of the form. This is what's happening with the drop down menu button I've added to my status strip, and context menus show up on the right side as well.

When changing a textbox border style to "none," and the font size to anything higher than the default 8.5, everything is fine unless if the letter goes downward ('g', 'y', 'j', etc). This is most noticeable with the g. I've linked a picture here, and I have no solution to have each character come out clearly. If I'm using another textbox border, it works fine. If I use the font size of 8.5, it's fine, but I can't have no border and a larger font. Though the textbox changes size it does not change enough to show the tail of the g. I can't change the size of the textbox because i

How can I reference the parent master page's property from within either the child master page's code behind Page_Load or aspx template page?

I have a page with Ajax Tab controls, within one of the tabs is a webcontrol that as a Telerik RadGrid, with Edit forms pointing to another web control. That edit form also contains Ajax Tabs and on one of those tabs, there is an Ajax modal popup of yet another webcontrol.The initial webcontrol works fine when used on it's own page, but the edit form fails to appear when the control is used within the Ajax Tabs as desired. The script manager is throwing the following error:
Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'xxx'. If it is being updated dynamically then it must be inside another UpdatePanel.

I'm currently having an issue where an updatepanel does an async postback and loses the tab order when the partial postback occurs.When you run through the tabs the tab order works correctly, but then you press a button and the partial postback occures the tabindex is reset.

Listen I'm very new to MVC 3.0 but I've been looking and looking for a simple straight forward tutorial for replacing an asp:UpdatePanel in the MVC world. There are lots of examples on the jquery function that needs to be called but since I don't know how to wire it up in MVC I'm still lost. Can someone point me to a hard and fast example on how I can do a simple "timer refreshed" partial view such as putting the date time on a _layout.vbhtml page?

I am using an asp.net update panel to refresh the content on a page when a menu item is selected.
Within the content that is updated are images which have a javascript reflection function which is triggered with the following line of code:
window.onload = function () { addReflections(); }
This runs fine when the page is first loaded but not when a menu item is selected and the update panel is run.
On previous projects using jquery code I have replaced document.ready with function pageLoad but there is no document.ready on this page.

I'm trying to execute some javascript code on my UpdatePanel's OnLoad event like so:
<asp:UpdatePanel ID="updDropDowns" runat="server" OnLoad="javascript:ResetButtons();">
But I keep getting "'javascript' is not a member of ASP.reasons_aspx".
I tried doing
Me.updDropDowns.Attributes.Add("OnLoad", "javascript:ResetButtons();")
But I can't reference the 'Attributes' property of an UpdatePanel in the VB code-behind.

I have a fully dynamiclly generated page that has a set of linkbuttons basically switching views in a UpdatePanel. All that is working great except for when I have a button that is generated that needs to invoke a function to manipulate the data in the Update Panel.
[code]...
So the problem is when the page_init is executed it does not know which linkbutton was selected so it never recreates the button and in turn never fires the event. I have seen people use the session to store the list of controls and/or the current frame but I don't see that as an acceptable solution. Surely there has to be a way to do this.Is there no way I can get the ScriptManager's current/previous step information outside of the Navigate event?Asp.net 4.0 with latest ajax toolkit.
