TextBox OnTextChanged Triggered Twice In Firefox?
Feb 4, 2010
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 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.

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:

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 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.

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 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.

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 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.

I have a formview with some templates. This is hooked up using objectdatasource. To the default layout I add some additional Label/Textboxes dynamically based on metadata in a database. I create the additional controls in the ItemCreated event using ParseControl on a Placeholder and populate the values in the DataBound event. This all works fine.
I have been modifying the extra textboxes using a ForEach loop in the ItemUpdated and ItemInserted events of the main formview. However this modifies each textbox regardless of whether the textbox has changed. What I want is to only modify the textbox if it has changed. I have tried to hook up OnTextChanged for the additional textboxes (using ParseControl) but the handler is never getting called. I thought maybe I was making a mistake in the execution order of the page but now I'm wondering whether ParseControl isn't hooking up the event handler correctly? Anyone come across this?

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'm trying to server an exe to Firefox from an aspx page. The aspx page handles the headers and the page is launched by our Flex GUI. Flex correctly launches the link for all browsers (including Firefox) so I'm certain that's not the issue.
The problem I'm having is when I try to download the file from within Firefox, FF downloads the file fine but it names it "Content". It has no extension and the file name is incorrect. All the other browsers download it with the file name I specified in the aspx page and they all have the .exe extension. I should note that if I rename the "Content" file to "Content.exe" it runs correctly.Below is the code I'm using in my aspx page -
protected void Page_Load(object sender, EventArgs e) {
string fileName = Request.QueryString["file"];
System.IO.FileInfo fileInfo = new System.IO.FileInfo(Server.MapPath(fileName));
