AJAX :: How To Get OnKeyPress On A Textbox


I am trying to implement the Microsoft Ajax.NET extensions to perform a
lookup on a key press of a text box.

What this will do is once a user enters a letter into the textbox, this will filter a list from a database and populate some filtered options for the user to choose in a seperate listbox. Any subsequent key presses will further filter this result set.

Now utilising the OnTextChanged property of the textbox, this works perfectly. Except you have to tab out of the textbox to trigger the event. So to make the on key press event work, in my Page_Load i added the onkeypress attribute to the textbox and specified this to trigger the text
changed event. tbSearchTerm.Attributes.Add("onkeypress",

Page.ClientScript.GetPostBackEventReference(tbSearchTerm, ""));

Now this kind of seems to work, but has a one character delay.

Example:

action: I enter the character "A" into the textbox.
result: Nothing happens

action: I enter an additional character "B" into the textbox
result: Results for the letter "A" are now returned

action: I enter my third character "C" into the textbox
result: Results for a search for letters "AB" are now returned.

This is causing a most undesirable effect.

How is one supposed to utilise an OnKeyPress action in the AJAX.Net
framework?

This was downloaded from:[URL]

And i have been unable to find another solution to this problem.

Difference Between Onkeypress And Onkeydown?
I have a form with a default button set.So when i press enter,form is submitted regardless of the focus. My requirement is when focus is inside fileupload control and enter is pressed,instead of submitting the form show browse dialog. So I created a panel and attached a onKeyPress event to this panel

fileUploadDocument.Attributes.Add("onkeyPress", "return ByPassEnter(event);");
<asp:Panel ID="fileUploadDocument" runat="server">
<div>
<uc2:FileUploadControl ID="ucdocxUploadControl" runat="server" ErrorMessageNoFileSelected="select a file for upload."
ValidationGroup="BrandLogoFileUpload" />
</div>
</asp:Panel>
function ByPassEnter(e) {
var evt = (e) ? e : window.event;
var key = (evt.keyCode) ? evt.keyCode : evt.which;
if (key == 13) {
document.getElementById('<%=ucdocxUploadControl.BaseFileUploadControl.ClientID %>').click();
CancelDefault(evt);
}
}
function CancelDefault(e) {
e.cancel = true;
if (e.preventDefault) {
e.preventDefault();
}
e.returnValue = false;
}

When i press enter on fileupload control, browse dialog shows up and when i choose a file or hit cancel on browse dialog,postback happens. e.returnValue = false should prevent the postback but even then postback happens. However if i change onkeypress to onkeydown,everything works and postback doesnot happen.

Window.location.href Not Working In Safari When Using Onkeypress?
I'm using an asp textbox and a search button. In Safari if I click the search button i get redirected to the search results page using javascript window.location.href. But strangely the same javascript will not redirect to the page if I press return in the textbox. Using the alert function I can see that window.location.href has the the correct url and the location bar at the top changes from the search page(default.aspx) to the search results url however when I click OK to the alert box the url at the top reverts back to the default.aspx page. It works on ie7/8/firefox/chrome but not safari. Here is my javascript,cs and aspx code:

function submitSearchOnEnter(e) {
var CodeForEnter = 13;
var codeEnteredByUser;

Mobiles :: Enter Key Does Not Fire The Onkeypress Event In Select Objects
In a nutshell, I have found that the "Enter" key does not fire the "onkeypress" event of a "select" HTML control when using Windows Mobile Internet Explorer. As you may have guessed already, I have a web server running an application in ASP.NET where different kind of computing equipment connect to, including PC's and Handhelds. PC's work fine, as well as Windows CE and Pocket PC's handheld devices. But when it comes to Windows Mobile, a particular control in a web page fails to process "enter" keys

AJAX :: ListSearchExtender But In A Textbox?
the AJAX ListSearchExtender will manipulate listboxes,dropdownlist etc.In another discussion here i presented a filter that does this exactly as i want(and better imo).What i need to know is, if there is some mechanism that you can type in a textbox and bellow you get the data that you want(p.e. typing a will present "aardvark","afoul","ant" ,typing an "f" after the "a" will only show "afoul", you get the point) not in a predefined listbox with data but possibly in some other sort of(ajax?) control.So in sort the data will be shown when you start typing.A simple example is a forum that you go to the search option and you want to find posts by a user.When you start typing you get a list below with matching user names.So this is doable at least with php sites using JS.SoP.S. This filter is for future usage so i don't need a fast "alternative".And i think it's JS time again (

AJAX :: Textbox Does Not Remember Entries?
I am using the TextBoxWatermark extender ASP.NET AJAX extender this works great, but i still want to have the comfort for my users, that the textbox remembers their entries e.g.:

Login=> TextBox with UserName

- if two people are using the same computer, they don't want to type UserName each time again instead click in the box and choose their UserName or start typing and their UserName is than suggested.

It seems to be a standard funktion that a TextBox remembers the entries you did. Unforantly when using the watermark extender on a textbox it simply does not work anymore.

Is there a way to enable this „feature" again?
 
When looking at the example of the TextBoxWatermark ASP.NET AJAX extender: [URL] it is not working their as well.

AJAX :: UpdatePanel - Get Focus On Textbox
I have run across an issue recently while incorporating AJAX into one of my applications. The issue demonstrates either my fundamental lack of understanding about how this technology works, or a problem in my implementation of it. I have created an bare-bones simple example to demonstrate what I'm seeing. I know how to remedy the problem, but I'd prefer the discussion center around *WHY* it's happening.

Here are the details.  Consider a project with a default.aspx. That page has two controls, Button1 and PlaceHolder1. The project also contains as usercontrol, uc1.ascx, which simply contains a TextBox control, TextBox1. The click event of Button1 dynamically loads uc1 into the placeholder via the Page.LoadControl method. All I really want to do is set focus to to TextBox1 after the control is loaded.  Without the UpdatePanel, I can do it two ways.  I can either put TextBox1.Focus(); in UC1's page load event, or I can register a startup javascript to find the textbox and use its focus() method. Either way works fine. See example code below.

Now introduce UpdatePanel. Enclose Button1 and PlaceHolder1 in the same UpdatePanel. The result, no focus to the textbox.  Move Button1 outside of the UpdatePanel, focus will work.  Fundamental question is - WHY?  Why does it matter where that button control is in relation to the Placeholder and UpdatePanel.  I've done a lot of searching on this topic and I've found lots of questions but not many answers.  Here's the code I'm using, to get focus to work correctly, move Button1 outside of the UpdatePanel:

Default.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<div>
<asp:UpdatePanel ID="up1" runat="server">
<ContentTemplate>
<asp:Button ID="Button1" runat="server" Text="Load UC1" OnClick="Button1_Click" />
<br />
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
Button1_Click Event:
protected void Button1_Click (object sender, EventArgs e)
{
Control ctrl = new Control();
this.PlaceHolder1.Controls.Clear();
ctrl = Page.LoadControl("uc1.ascx");
ctrl.ID = "DynamicCtrl";
this.PlaceHolder1.Controls.Add(ctrl);
}
uc1.ascx:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="uc1.ascx.cs" Inherits="uc1" %>
UserControl 1 <br />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
uc1.ascx.cs:
using System;
using System.Web.UI;
public partial class uc1 : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
//use either of these two lines in the example
//this.TextBox1.Focus();
ScriptManager.RegisterStartupScript(this, typeof(UserControl), "focus", "document.getElementById('DynamicCtrl_TextBox1').focus();", true);
}
}

AJAX :: TextBox Value Not Being Updated From Code-behind?
I have a webform that accepts a date range to generate PDF reports. I had to place a PostBackTrigger on the updatepanel and assign the button thaat generates the reports because the Response.ContentType is being set to "application/pdf".

The problem is I am updating the textbox value to the count of clients that are left out of the report generation in server side code, the count always come back as 0. I have tried multiple panels with no luck. The textbox is in the main updatepanel with the print button and that still does not work.
