Web Forms :: Textbox In My App In Which I Have Code Behind In The "onTextChanged" Event That I'd Like To Execute?
Oct 1, 2010
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.

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):

And here is the server-side:

In text box onchange i call the javascript function
for calculating txt5 value
i.e.
in javascript method,
txt5.value = parseFloat(txt1.value) + parseFloat(txt2.value) + parseFloat(txt3.value) + parseFloat(txt4.value);
and
text box txt5 enabled=false,autopostback is true
protected void txt5_TextChanged(object sender, EventArgs e) { // here based on txt5 value i getting records from database and doing some calculation and display those value in txt6,txt7
}
The problem is the textbox txt5 can;t post back when text change from JavaScript function.
How can I do postback when text box value bind from JavaScript function and enabled=false.

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.

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.

I am using the following line is my code and the onTextChanged event is not firing. But when I use the onClick event on the same code, it's firing.
textbox1.Attributes.Add("onClick", "SetValue();")
But I need to do my calculations only if the value in the textbox is changed not when the user clicks on the textbox.

I have an gridview with 3 columns. As default I entered for each columnns an headertext, but depending on an language parameter in the data the headertext is changed on page_load with a SetLabels function.
Recently I added an templatefield textbox with an autopostback=true and an ontextchanged event :
When a user changes the text in the textbox all events are executed properly BUT my headertext is set back to the default value (from the .ascx) even tho page_load event is executing properly WITH the SETLABELS function.

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() {

I have a TextBox control with OnTextChanged handler. The event handler is working fine most of the time, but when the user changed the text and press Enter in FF, the OnTextChanged event is called twice. I observed the problem in Firebug that the first request is actually canceled because of the second event.
Test.aspx
<%@ Page Language="C#" AutoEventWireup="True" CodeFile="~/Test.aspx.cs" Inherits="T.Test" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
[Code]....
Put a break point @ var a, and you'll be able to see that after changing text and press enter in FF (v3.5.7), the OnTextChanged event is invoked twice.
So my question is, what's the best way to properly handle OnTextChanged event so that hitting enter in the textbox doesn't trigger double postback.

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.....

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....

I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.

I have a web app that needs to do two things at the same time. After a user clicks a button on the site, a javascript function needs to execute and while thats working I need the server side code for the button click to execute without waiting on the client side to finish.
To be more specific, the client side function takes about 23 seconds to complete, and while that is running the server side code promts the user for printing a document. So I need the javascript to run "in the background".

I am having a gridview in which there are many columns. The Last column is button column with command name as Select.
In row command event, I am creating a webreqest instance and passing the url of the required page in my application, and based on the response status code, updating the column value for that particular row.
This is working.
What I want is this should be asynchronous. Means, if I click the first row Select button, then it should fire and process request. Meanwhile I should be able to click other row's Select button, even if the previous button's click event is still in process.
Means the communication should be asynchronous. Even if
