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.
View 2 RepliesMy LINQ query:
Dim groupedData = (From p In pData _
Group By p.TruncParam Into Group) _
.SelectMany(Function(g) g.Group) _
.Select(Function(d, idx) New With { _
[Code]...
When the TruncParam changes, I would like the index (idx) in the Select clause to reset to 1. So, in the list above, the Index should be SOLUB0001, SOLUB0002, INSOL0001, INSOL0002...CLRES0001, SUMCA0001, SUME0001.
How should I alter the LINQ query?
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 got on my form textboxes, checboxes but also a groupbox which holds texboxes.
The idea is to be able to clear and reset all of these by clicking a reset button.
At the moment i got this
Private Sub ClearFields()
Dim ctrl As Control
[Code].....
But ofc Me.controls isn't gonna get involved with the stuff in the groupbox.
Ok, so I am building my own program to control a video player I have through telnet, I have everything else working except one thing.I have a reset button to reset the player, when I press it, it sends the string "Reset" and the unit resets without a problem.But when I add a code to close the winsock connection upon reset, it doesn't send the string to the unit. I am sure what is happening is the winsock is getting closed at the exact same time it is trying to send the string and so it fails to send, how do I make it close winsock AFTER the string has been sent?

View 1 RepliesI 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.

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 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'm trying to execute some javascript code on my UpdatePanel's OnLoad event like so:
<asp:UpdatePanel ID="updDropDowns" runat="server" OnLoad="javascript:ResetButtons();">

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 UserControl inside UpdatePanel, how to update the user control when clicking a button
View 1 RepliesI 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.
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.
