Jquery - Delay A ASP.NET AutoPostBack So JavaScript Fires First?
Mar 2, 2010
I've got an odd situation with a text box and an autocomplete setup on my page. I'm using a JQuery based autocomplete on a text box that has AutoPostBack="True". This works perfect if I use the keyboard to select an autocomplete item, which then fires Jquery to fill in the text box, and then when I tab out of the box the AutoPostBack fires. If, however, I click on an autocomplete item, my text box loses focus first and the AutoPostBack fires before the Jquery has a chance to change the text in my text box. Is there a way to delay either the PostBack or the Jquery so that they don't fight each other? I'm thinking it may have to be the PostBack that gets changed, since the JQuery would lose it's state on the PostBack.

I have a ListView with the Activation property with HotTracking. There appears to be about a 2 second delay between when the user clicks the item and the event fires. Is there a way to get the event to fire immediately upon the user click?

<asp:TextBox ID="uitxtCamLastVisitDur" runat="server" CssClass="tooltip"
Width="65px" Enabled="False" ToolTip="Indicates a required spending on the member's last visit."></asp:TextBox>

I'm working on a web page that takes multiple PNG images and merges them into one image so the user can download the flat image. I would like to add a hue or color adjustment (like color balance in photoshop) so I can adjust the different PNG image layers without having to create a separate image for each hue. Right now I'm using ASP.net/VB.net and some jQuery and the System.Drawing.Image method to merge the images. I can't seem to find any information on doing this for the web without using silverlight or flash and I do not want to use either.

I want a web page that pops up a JavaScript alert when a bar code scan is done. I don't want to tie the event to any visible control such as a textbox so thus, I won't have focus on any control to capture the scan input. Can this be done with JQuery?

my problem is that my company does not want to serve up the .json MIME type, so I have to use ASP.NET to fetch the JSON file from the file server. Currently I have jQuery that does a getJSON and traverses the JSON object to build certain elements of the page. Is there a way I can use ASP.NET (VB) to give the object to my jQuery script after I fetch it?

I have a jQuery 'toggle' function on a table that I am using in conjunction with an asp.net gridview. I have pagination on my gridview and when I click on the next page, it posts back and therefore closes the Toggle/Table - I need a way of keeping it open. I have had a similar issue in the past with the Accordion function but resolved it via this method
<asp:HiddenField ID="hidAccordionIndex" runat="server" Value="0" />
<script language="javascript" type="text/javascript">
$(function () {

Upon a javascript button click, I'm using jquery to post to a url:
$(".optionClick").click(function () {
var caseOption = $(this).attr('title');
$.post("../tracking/RecordClick.aspx?page=gallery&item=" + caseOption);
});
On the page being called, I'm using the following vb.net code to retrieve the querystring variables and write them to a database:Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]...
Each of the javascript blocks above worked locally as intended but failed in the same manner with multiple DB writes and Firebug "Aborted" status.If I call the url+querystring directly via the browser, everything works as expected. (Edit) Also tried using the full path url in the code above - no improvement.

I am attempting to create a ASP .Net (VB.Net) custom control for an auto-complete drop down that uses jQuery auto-complete.The basic flow is the consumer of the control will set some properties (such as the data source) which will then be injected as javascript to initialize the autocomplete.There are a lot of pieces involved so i may have missed posting some of the code, please comment if you think something is missing and i will add it.the consumer's code behind (PreInit event):
myDropDown.DataCallback = "testFunc";
the DataCallback property in the control:
Public Property DataCallback As String
the options object creation and javascript injection in the control code behind (PreRender event):
Dim _serializer As New JavaScriptSerializer()
Dim optionsObject As New Dictionary(Of String, Object)
optionsObject.Add("source", DataCallback)
[code]....
when i debug into the initialize function, i see options has one property, source, with the string "testFunc" as it's value. what i need is for source's value to be testFunc (not as a string) so it can be executed as a callback in autocomplete instead of autocomplete thinking it is a URL.

Access <asp:table> table rows added by javascript in asp.net webform . Apologies for the duplicate question but I'd really like an explanation why this is the case. It is probably due to my lack of understanding on how browsers process HTML tables on submission to the server.If I have a <HTML> table or an <asp:table> control on an aspx page and I add rows to it client-side using JQuery / Javascript, why can I not include these added rows in a post-back to the server?
I've been trying to get this to work and it looks like I can't do it based on the answer to the previous question. But can someone explain why this is the case? The table itself can be returned in the post-back but the only rows present are the rows that were part of the table when it was sent to the browser originally - it does not include the rows added by the browser.there was a way to include these new rows in the post-back, the same as any client-side user input?

A form has many buttons. One of those buttons contains code to update the TableAdapterManager. One of the many TextBox controls has code in a Validating event handler. There is code to make sure a US phone number is formatted properly.If the user tabs out of the TextBox the Validating code works perfectly and show a message to the user if the phone number is not properly formatted and the focus is place in the offending TextBox.If the user clicks on a button that has code to update the TableAdapterManager the Validating code fires but instead of focus remaining on the offending TextBox, the code in the button Click handler also fires.
I would like to stop the button code from firing.Here is the code for the Validating event of the TextBox:
Private Sub TextBoxPrimaryPhone_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBoxPrimaryPhone.Validating
' Make sure the phone is formatted correctly.
[code]....
What additional coding to I need to include so focus remains on the TextBox?

I know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

I have a project where I am taking multiple checkboxlists and totaling up points based on which boxes are checked in a certain list. I then display the sum of these points to a text-box. I do this for every checkboxlist.
The problem is this: when one checkboxlist gets changed, the other sums get removed from their respective text boxes. I have attempted this both with read-only set to True (which is the ideal setting in my case) as well as set to False (as per Problem in using AutoPostback in asp.net c#)

I am trying to use something like a "state" combobox that when selecting a state only certain "cities" will be dispalyed in a second combobox.
I know this is possible in asp.net with autopostback, but vb I have no idea.
