I need to display a popup dialog box when an Aspx page first loads. I do this inside of the page load method
with PageIsPostBack.
How can I prevent the popup from being displayed though when the user hits the refresh button or F5 button.
Or the back button?
if(!Page.IsPostBack)
{
// Dispaly popup here
}
This has been driving me nuts all day. I've seen this problem crop up here a few times, essentially I have a drop down list that populates a form below when it's changed - basic stuff. On first page load everything is fine, but when the dropdownlist is changed, it's entirely blank after postback and the SelectedIndexChanged event never fires. I believe it all points to a viewstate problem. Here's the code..
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="EditUser.ascx.cs" Inherits="Controls_EditUser" %>
<asp:DropDownList OnSelectedIndexChanged="SelectedIndexChanged" AutoPostBack="true" ID="UsersList" EnableViewState="true"
runat="server" DataTextField="EXTRANET_USER_EMAIL" DataValueField="EXTRANET_USER_ID">

I am a problem with Postback event.
I have a web page (aspx) which takes longer time to load the page. If this page is loading and if user requests same page by clicking menu link again, it is considered as not postback and page starts loading again (as soon as it finished first page load).
I want to prevent this from happening. When page is loading and user requests same page again, it should not process those requests and should be neglected.
This aspx page is requested from menu (which is designed on seperate master page).
I have 2 checkboxes (yes/no) that when selected cause the entire page to refresh during postback mode. How can I elimiate this?

I have a textbox that is set to readonly so users won't try to type something in it. It is then populated when a treenode is clicked. I want to validate what is in the box after it's populated from the treenode click but if i have it set to readonly, in the codebehind it shows up as an empty string. if i take the readonly off it shows up populated. what would you do about this?

when i click on add button to add second row the values from first row get vanished. So how i can maintain the viewstate for those controls
I've got some textboxes in a panel, that I want to disable client-side upon radio button selection. I've got it basically working - but I discovered that javascript's control.disabled = true still allows the user to type in the textbox. So I've moved on to control.readOnly (in addition to disabled) - that seems to give the result I want.
Problem is, setting readOnly at the panel level doesn't seem to propagate down to the contained controls (the textboxes). I still have to call textbox.readOnly directly in order to get the no-typing-allowed result I need. And this makes the whole panel-concept useless for me in this instance.
Am I doing it wrong somehow, or is this just the way panels work (i.e., can only make textboxes readOnly by directly manipulating its property)?

How to get value for CalendarExtender from readonly textbox
I have a TextBox in my page
<asp:TextBox ID="TextBox1" runat="server" ReadOnly="true"></asp:TextBox>
I am not able to get the changed value ( I have attached a ajax calender with this textbox)
in code behind because it is readonly
I can do this using TextBox1.Attributes.Add("readonly", "readonly"); or I can get the correct last value using Request.Form[TextBox1.UniqueID]
Why value is available when we use code behind attribute add
"How to: Customize the ASP.NET CreateUserWizard Control" [URL]
In the final example, a wizard step, "CreateUserWizardStep0", is used to validate the username as unique before proceeding to the createwizardstep that collects the remainder of the user's registration information. In order to keep the user from changing this username on the next screen I have set the textbox for username to ReadOnly=true. However, this changes causes the registration to fail without ever executing the method "CreateUserWizard1_CreatedUser."
I have a frame with several radio buttons where the user is supposed to select the "Category" that his Occupation falls into and then unconditionally also specify his occupation.If the user selects "Retired", the requirement is to prefill "Retired" in the "Specify Occupation" text box and to disable it to prevent it from being changed. The Specify Occupation text box should also no longer be a tab stop. If the user selects a radio button other than Retired the Specify Occupation text box should be enabled and once again and the Specify Occupation text box should once again be in the normal tab sequence.
Originally, I was setting and clearing the disabled property on the Specify occupation textbox, then I found out that, upon submitting the form, disabled fields are excluded from the submit and the REQUIRED validator on the Specify Occupation textbox was being raised because the textbox was being blanked out.What is the best way to solve this? My approach below was to mimic a disabled text box by setting/resetting the readonly attribute on the text box and changing the background color to make it appear disabled. (I suppose I should be changing the forecolor instead of teh background color). Nevertheless, my code to make the textbox readonly and to reset it doesn't appear to be working.
function OccupationOnClick(sender) {
debugger;
var optOccupationRetired = document.getElementById("<%= optOccupationRetired.ClientId %>");
