C# - How To Retain Password Field Value On PostBack
Aug 19, 2010
Right now I have an asp:Wizard with 3 Steps.
Create User
Form to Email
Summary of Fields
When the finish button is clicked on the third step I would like to Create the user and send the form. I have the logic for this written but the only problem I have is the when the next button is pressed on a wizard, a PostBack occurs and my password field:
<asp:TextBox ID="txtPassword" TextMode="Password" Width="70%" runat="server" />
Does not retain its value.

I have an IEnumerable< T> which is declared on the page like this:IEnumerable< Person> person;When the page postsback, the person list is null. How can I retain the values of person list without declaring it as static? Sr. devs in my company say that you should not declare the list as static.

We currently have a page with several user controls (8 of them) and when a control that is contained in an updatepanel initiates a postback the focus is not retained. In some cases, it looks like the focus is sent to the top of the page, and in other cases the focus looks like it is sent to the control with the TabIndex=1.
I have tried 3 different solutions and they all end up with the same result.
The first two were from article:
[URL]
Solution 1: At the end of the server event executed in postback, add:
[Code]....
The article says both of those solutions worked, but for us, neither of them did.[Code]....
ASPX.CS
[Code]....
[Code]....
In all 3 scenarios the control we want to have the focus gets the focus for a split second and then the focus is cleared (set to the top of page, or TabIndex=1).

I have a form that is used to add and edit data. Based on a dropdown selection, the form is either prepopulated or left blank so you can add new data.
I have a password field that is set to TextMode="Password" and works fine when adding new data, it displays ***** as you type..
Now if you select from the dropdown and there is already a record on file, it populates the form to allow you to edit the information.. Now i DONT want to display the password in plain text, but i want to populate the field so if they make any changes all field data is kept and table is updated with all of it.
I already debugged the page and my variable is being set with the password, but the textbox doesnt even show the ***** for the password value.

This is a problem I'm facing in a webapp I'm currently working on. So instead of cluttering the question with unrelated code, I recreated the problem in an isolated, simplified webapp that only demonstrates this issue.
I have a web user control with just this as its content:
<% if (ShowAlertScript)
{ %>
<script type="text/javascript">
function AlertMe()
{
alert('Hello World!');
}
</script>
<% } %>
<input type="button" onclick="AlertMe()" value="Say Hello" />
And its codebehind has nothing more than the boolean definition of ShowAlertScript. This represents a control I have in the big webapp that has two modes: input mode, and display mode. When in input mode, it has a large javascript block that is only useful then; it does some cool stuff to help the user input the info.The way this control is laid out in the big picture is as follows:
<asp:ScriptManager runat="server" />
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:MultiView ActiveViewIndex="0" runat="server" ID="mvw">
<asp:View runat="server">
<asp:Button runat="server" ID="btnSwitch"
OnClick="btnSwitch_Click" Text="Switch" />
</asp:View>
<asp:View runat="server">
<uc:MyInputControl runat="server" ID="micInput" ShowAlertScript="true" />
</asp:View>
</asp:MultiView>
</ContentTemplate>
</asp:UpdatePanel>
When you click btnSwitch, it simply switches to the second view with the user control. Notice how I have the ShowAlertScript already initialized to true. The potential output is that since I'm "showing the alert script" within the user control, the AlertMe() function will execute when you click the input-button element, because it's written out according to the inline if statement.
If you run this code I gave you so far as is, it will not work. The browser will say it can't see the AlertMe() function; it's undefined as far as it knows. But if you take out the UpdatePanel (or disable the ScriptManager's partial rendering), it will work just fine on a full postback when you click btnSwitch.
I want it to work on a partial postback, because this whole thing is a small piece compared to the rest of the page, and I don't want to do a full postback every time they switch views. Apparently, the ScriptManager doesn't even bother re-rendering the ascx file for possible changes. Either the ScriptManager is not smart enough, or there is an option I'm missing to let it render the <script> so I can invoke its methods on the client side. A potential answer someone might suggest is "why don't you take out the javascript, put it in its own .js file, and have the page reference it so it's available to the control?"
That won't really work with me, because the script block does some initialization and modification that pertain to that single control instance, not to all others on the page.
In turn, you might also be concerned that if I have more than one instance of the control, I end up with copies of the same script. Not really; there will only be ONE input mode of this control in a page at any given time, it's just that I have those two modes in two separate views and I let the user switch between them.

I have the example working but I added a Select Command to the Detail grid for the purpose of selecting a detail record which will redirect to another page. The problem is that when the Select command is clicked the expanded detail grid collapses as if I had clicked the minus. The page and codebehind are:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Search1.aspx.vb" Inherits="iDCA.Search1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

The graphic designer of a project I'm building a web site for chose jquery.tools [URL] for a tabs tool in the site. Unfortunately it seems that the tool doesn't behave properly on a postback in IE7 or IE8 (it does behave properly in FireFox, Chrome and Safari). Does anyone have experience using the jquery.tools with asp.net? and know how to retain the tab index on a postback? I've tried a lot of things and can't get it to work. The code i'm using now is as follows:
$("ul.tabsScenario").tabs("div.panes > div");
var tabIndex = $('#ctl00_ContentPlaceHolder1_EnInDeToekomst1_HiddenFieldTabIndex').val();
$("ul.tabsScenario").tabs('select', tabIndex);
where the tab index is stored in a hidden field (HiddenFieldTabIndex). The above code works fine in Firefox, Chrome and Safari, but not in IE7 or IE8. I am using a ScriptManager and UpdatePanels, but in an extremely simple website example I can't even get the jquery.tools tabs tool to work. There are some unanswered posts on the Jquery.Tools forum concerning this topic, but yeah, that doesn't help much. I've already determined that the jquery.ui tabs tool works well after a postback but that would cost a lot of refactoring in our project as far as html and css goes. I'd like to avoid that.

is there a way to safely keep the value of a password field during postbacks in ASP.NET?
I was thinking of the viewstate, but I don't want to print it clearly in the HTML code by setting the control value equals to the viewstate content at every postback.

I am looking to create a confirm password field using asp.net MVC2 that works on the client. All my other client validation is done with MicrosoftMvcValidation.js by just adding the Html.EnableClientValidation(); call.
Some of my considerations. Should the confirm password be part of the model object? Using that approach i have created server side validation by creating my own model binder.

I have an asp.net textbox like this:
<asp:TextBox ID="PINPad" runat="server" Columns="6" MaxLength="4"
CssClass="PINTextClass"></asp:TextBox>
It is, as you might have guessed, the text box from an on screen PIN pad. Javascript fills in the values. The page is posted back every five seconds (using an update panel if that matters) to update various other unrelated items on the screen. This works just fine. However, when I convert it to a password text box, like this:
<asp:TextBox ID="PINPad" runat="server" Columns="6" MaxLength="4"
CssClass="PINTextClass" TextMode="Password"></asp:TextBox>
Then whenever the page posts back, the text box is cleared out on the screen and the textbox is empty (though during the timer event, the value does make it back to the server.)

I'm trying to user ValidatorCalloutExtender on my login page but I'm having some trouble with it. I have two TextBoxes, two RequiredFieldValidators and two ValidatorCalloutExtenders. Here's my page's code:
[Code]....
So, my problem is quite simple, I guess. When the user press "ButtonLogin", the first ValidatorCallout is displayed requesting that the user enter his username. The validation text for the password field isn't displayed. If I enter the username and then try to post the form again, the validation text for the password isn't displayed at all. The text is displayed only after I click on TextBoxPassword. Is there any way to solve this? If I wasn't using ValidatorCalloutExtender, text for both validators would be displayed. So, I'm guessing that internally both validators actually trigger. The second isn't displayed because the first one is already been displayed. But even after entering text on the first textbox, the text doesn't come up. I believe it's still thinking that the first validator is been displayed.
