AJAX :: OnTextChanged Event For Checking Username Availability?
Nov 28, 2010
I am having a big problem with the OnTextChanged event of a textbox....
I have tried several different scenerios and just don't seem to be getting it to work right...
I either get a full page postback which is not what I want or get a very peculiar extra textbox added to my page after OnTextChanged is executed...
currently the update panel is working as expected but it inserts an extra textbox into my form "magically"... so strange...the textbox that is added keeps a running history of what is submitted...you can take a look here at the behavior.. it is the email form in the middle of the page
Sample
Here is what I am working with...
[Code]....
and then in the code behind I insert a image to let the user know what is going on..
[Code]....
not sure why an extra textbox is added but everything else seems ok.....

I have tried the following solutions in my ASP.Net(C#) website for which I had previously configured ASP.Net membership module.http://riderdesign.com/articles/Check-username-availability-with-JQuery-and-ASP.NET.aspxhttp://www.ajaxlines.com/ajax/stuff/article/validate_username_using_jquery_ajax_json_and_aspnet_web_method.phpBut when my username textbox losses focus, a following error appears besides my textbox,
[Code]....
Why it is giving this error? Why it is not locating CheckUserName() function that I have added in myPage.aspx.cs file which is it admin's folder?Is it the path issue that I have given in JSON? or its due to something else !!!

have once posted a question but am really not sure how can I go about using AJAX to do it. Some have suggested using jQuery but I'm not sure how to use the jQuery so any suggestions on ASP.NET AJAX? I've already got the codes for the non-AJAX method(using a select statement), but thought that AJAX will be more dynamic.
how can I do it? Here are the codes I used for the non-AJAX method. It works fine, just that I want to use AJAX to do it.[Code]....

Is there any way to check a web service's availability and get an alert whenever it is down?
I am supporting a very critical application and it went down few times because the webservice that it is supposed to be using was not accessible to it. So is there a way in which I could set up some monitoring and poll the web service periodically to check if it is available or not.
If calling the web service is the only way to check, I have a method in the web service which is supposed to return true.. How do I write code(windows app/web app/windows service/anything) so that it calls this method every 5 mins and sends me an email.
What would be the best way to setup the periodic polling, and how do I do it?

Are there any other events besides the OnTextChanged event? Like is there a key up event of some sort?
What I'm trying to accomplish is when a user fills in this text box it automatically fills in a couple other text boxes.

On my page, the user is basically registering for a site and I am trying to do a username availability check, without doing the javascript myself(not very good with it yet). The code that is shown below shows the contents for 1 out of 5 textboxes on the page. They all are in the same validator group that is triggered by a button. I have tested the availability query check itself and it works, but only once the submit button is clicked. Nothign is happening when I tab away from the textbox after enetering text.And this page is actually 3 tabs (not sure if there is some sort of a bug that involves tab containers possibly).
I here's the client-sdie code for the page (at least what pertains to this):
[Code]....
And here is the server-side:

I have two textboxes which are start and end date fields. I want to change the calendar control that I display to jQuery UI's datepicker. Problem is when I select a date from the datapicker, OnTextChanged event or validations do not fire as it does when I type values in the textboxes or select it from a calendar control and tab out. CausesValidation attribute supposed to help out but didn't. I can just keep the calendar control.
<script type="text/javascript">
$(document).ready(function() {
//Associate jQuery UI datepicker[code]....

I have textboxes being generated by a repeater that use OnTextChanged with autopostback enabled so that I can know when when the values change. This all works perfect.The problem starts when I try to click on any buttons on the page. The loss of focus triggers the event for the OnTextChanged; however, the event for my buttons never get fired. I checked this in the debugger and while debugging if I put a break-point in the page_load it will call both; however, without the break-point it still only calls the OnTextChanged event.I found this post on JavaScript. If my problem is also JavaScript related, why does the clicking of the button fire in debug mode?

I am using a calendar extender which is an Ajax control I am selecting a date but the event is not fired.
The reason I am doing this is because I am setting an expiry date based on the date selection.
<asp:TextBox ID="start_date" Width = "165px" Height = "24px" runat="server" OnTextChanged="start_date_click"
></asp:TextBox>
<asp:TextBoxWatermarkExtender ID="TextBoxWatermarkExtender1" Enabled="true" TargetControlID ="start_date" WatermarkText="Start date" runat="server">
</asp:TextBoxWatermarkExtender> <asp:CalendarExtender ID="CalendarExtender1" Enabled="true" runat="server" TargetControlID ="start_date" >
</asp:CalendarExtender>
The code behind
protected void start_date_click(object sender, EventArgs e){
DateTime begindate = DateTime.Parse(start_date.Text);
exirydate.Value = Convert.ToString(begindate.AddDays(days));
}
Is my codebehind code correct. Am i not doing in a right way.

I have a textbox in my app in which I have code behind in the "onTextChanged" event that I'd like to execute
without doing an entire page post back .
I can't use use AJAX not an option for me (corporate thing).
Anyways, I have been struggling with the specifics on implementing ICallbackEventHandler. Or is than another way I can/should do this.The code in the textChanged event pulls a dataset from the DB and does a validation.

How can I get a gridview (that is inside an update panel) to update/filter whenever something it typed into a related textbox outside that panel..( possibly in another update panel)?
As in Google. When you start typing, it starts autocompleting for you by looking up words in the background using the text you've typed.
I want, in effect, for a user to start typing in a textbox (say "Order #" textbox) and each time a character is typed, to trigger an update to a gridview that has a 'search param' in it's SQL Datasource SP that plugs the textbox's text into the where clause of the select inside the SP...
make sense? I have the SP and all other related code, I would just need to know how to create a JS function (preferably via server-side using something like:
txtOrderID.Attributes.Add("ontextchanged",....
Rather than hardcoding client-side JS....
