I am developing a web application in Visual Studio 2008 using ASP.NET with VB. I am using a ComboBox control from the AJAX Control ToolKit. The ComboBox gets populated from a database.On Page Load the focus is on the ComboBox control. The user can use the Down Arrow Key to drop the listed items, move up and down through it and on pressing Enter key on the highlighted item the other controls on the page (such as Text Box, DropDown List) get populated with data related with the selected item from the ComboBox on which the Enter key was pressed.What I want is that if somebody uses mouse on the ComboBox items and clicks any one item the data related to the clicked item should populate the other controls. This should also work on Lost Focus.So how do we write the Mouse Click and Lost Focus events for a ComboBox control from the AJAX Control TookKit.

Is there one simple test that a person can do that covers all options where there could be a null, or "" value. When I google, I see so many options. I see:
if txtBox1.text IsNot nothing
if txtBox1.text.toString isNot nothing
if txtBox1.text <> ""
if txtBox1.text.toString <> ""
if isNull(txtBox1)
Is there on test that can cover them all?

I have some code where I need two separate required field validators for one control, both in separate validation groups which are then validated by two separate buttons.This approach works well when the buttons are clicked but both validators show if I enter a value in the textbox and then remove it.
Is there a way to turn this"lost focus" validation off? I only need it to validate when the buttons are clicked.
EDIT,Unfortunately, if I set EnableClientScript=false then I dont have any client notifications. What I want is for the dynamic error message to show (effectivly in the OnClientClick event of the button) but not the "lost focus" of the textbox.Is there some way I can disable or "unhook" the lostfocus client event?
EDIT,A combination dDejan's answer and womp's answeer here sorted the problem perfectly.
My final code looks like this (for anyone else with a similar situation)...
Javascript...
<script type="text/javascript">
$(document).ready(function() { [code]....
So, now there is no validation until a user clicks either the "Get Email Confirmation Code" button or the "Register" button. If they click the "Get Email Confirmation Code" button all of the controls validate apart from the textbox where the user is to input the email validation code and we only see one validator message.
If they click the "Register" Button then all of the controls validate and we only see one validation message.If either button is pressed, the user goes back, adds and then removes some text then we only see one validator. Before this change you used to see both messages saying the same thing.
Does text box have "lost focus" event?For example, there are two text boxes, txtAccountNumber and txtName. Once user inputs account number into txtAccountNumber and move to txtName before inputting name, I want to fire a sub to verify this account number.

I've got an application that uses jquery ui datepicker on an asp.net textbox control.The control is working as intended, but I've noticed that when you postback from a server call (via submit button), the entered value gets lost in the application.Was wondering if you all have experienced this? And what measures that you have to do to prevent this?Here is my code:HTML:
<asp:TextBox runat="server" ID="txtCallsMadeFrom" class="field" EnableViewState="true">
JQuery:
var callsMadeFromId = '#<%=txtCallsMadeFrom.ClientID %>';
jQuery(callsMadeFromId).datepicker({ showOn: "button", buttonImage: "../images/calendar.gif", altFormat: 'dd/mm/yy', buttonImageOnly: true, onSelect: function () { } });
I have a search page with 3 TextBoxes that users can filter a search with.
I have put the focus on the TextBox that contains text. If more than one contains text just focus on last TextBox.
[code]...
After the code runs and a user searches, the focus comes to the beginning of the TextBox, not the end where it would be presumed. How to put insert marked at the end of that TextBox?
Its an strange issue for me. one of my textbox is not getting focus in IE6 and 7. i also try this one this.textbox1.focus();
