Asp.net - Running Javascript Whenever UpdatePanel Refreshes?
Aug 10, 2011
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 am have been trying to teach myself ASP.NET and Javascript for a project and have been stuck on one problem for literally dozens of hours now. I found a really nice javascript drag-and-drop list online, copied the source offered and split the css into a .css file, the javascript into a .js file and the HTML and reference into my asp.net page. It worked perfectly. Next, I replaced the javascript list with a static HTML list populated with the same data, wrapped it in an UpdatePanel and set up an "edit order" button to swap the static list's HTML for the javascript list's HTML when the button is pressed.

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">

I'm looking for a way to run Javascript in an instance of WebBrowser. Ideally I'd like to include a file using [Code] Problem is, the only way I'm seeing to run JS in the browser so far is by navigating the browser to a javascript) url, and I'd like to avoid that. There must be a way to interact with the DOM and add the code that I want to run in there. Right?

If I use IE I can visit the website I want and click the 'Next' button and life is good. If I open that same website using the webBrowser control and click the 'Next button I get a javascript error message.I'm not doing anything in the code to manipulate the website. My goal, eventually, is to have some level of automation; but at this point, I get the javascript error and a pop-up and it screws everything else.

Today I'm having a play around with VB.NET and looking at making a little Task Manager kind of
thing; I've completed the little bits like populating the running processes and such, but noticed
that on the Task Manager provided by Microsoft, the Memory updates at a regular interval butnothing
else refreshes, where when I try and reload the running processes to get the updated memory usage,
the whole thing refreshes which doesn't look professional.Also, while I'm on the subject - how can
I make a DLL call to "kernel32.dll" to gain more access of the processes, IE controlling the
windows and such.

In an application I have, when a user types in a textbox, the data in a listview is refreshed to reflect what the user is typing.As it stands, it does a refresh after each key is entered.Is there any way to smartly wait until the user has finished typing before initiating a data refresh?

I am developing an application, for a university project, which is using GDI to draw a flag, my application is also equiped with an undo stack, which is, essensially, where the problem is, so what happens is: I push the draw button to draw a box, when I do that, the solution normally creates the box and stores the object to the undo stack; however, when I ask it to undo the box, and refresh the panel, it randomly adds, endless threads to the undo stack, additionally, everytime that I set the panel to refresh in the undo procedure, it affects the draw procedure; therefore, when I tell it to draw a box, it fills the undo stach with five threads at a time, sometimes, it fills it with much more than five, and sometimes it keeps filling up the undo stack, untill I stop the debugging proccess. This is my code:

I have a basic page which has fields that I read from the database and write to it. I would like to know where I should call the insert and read commands. I know about age_load but heard about page_loadcomplete.I noted that when the user refreshes the page, for some reason the sqldatasource loads the old data(before the write) even though new data has been loaded on the form.

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'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 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.

I'm building a simple game in an ASP.NET/VB.NET web app. The game has a UI made up of several ImageButtons. The web page's code behind file holds an instance to the game object which will manage each turn taken by players. Everything worked when the Game object's methods were Shared. The problem occurred after refactoring to make the game object work as an instance instead of a shared class. Now, when the action returns to the code behind, the instance of the game object is nothing.
The code bits:
Public Class _Default
Inherits System.Web.UI.Page
Private _gamePanel As Panel

I'm trying to speed up my Repeater so that not as much HTML has to be resent via the AJAX UpdatePanel on each call.
So here's what I have (a very much simplified version):
<asp:Repeater ID="rptContactSteps" runat="server">
<ItemTemplate>
<p>Script:<br /><%#mobjSDIT.FormatText(Eval("script"))%></p>
[Code]....
So, when I click 'btnSaveAndCompleteLastStep' I want all the UpdatePanel in 'rptContactSteps' to update. Having the UpdatePanel inside the ItemTemplate should help prevent having to re-load the html/text that populates the Eval("script") & Eval("notes"), since the value of these variables could be very large and over a 3G connection this could be very costly (in time & money).
I though by adding the async trigger it'd work as I have used this type of trigger before, but not when inside the Repeater. Currently the UpdatePanels aren't getting updated at all, except from the one from which the button was pressed.
