MVC :: Bug - Model Does Not Get Updated When Changed In Code ?

Feb 3, 2010

I have a page that shows the value of a property of my model. The value of that property is changed in the action-method of the controller (that recieves the model as a parameter). It turns out that this line of code:

<%= Html.TextBoxFor(m => m.Problem)%>

does not represent the value that it got in the action-method-code (just the value it got from the POST), but this does:

<input type="text" value="<%= string.IsNullOrEmpty(Model.Problem) ? "" : Html.Encode(Model.Problem) %>" />

Is this a bug or is some caching-mechanism working against me?

BTW, it is especially annoying when using HIDDENs, because the user can never change that value at all... That's how I found out...

I have a demo-project demonstrating the problem here for download. It is based on the default-application, so very small.

Installation :: Not Changed The Webconfig, Only Changed Pages' Content/code Behind?

Jan 13, 2010

After some code change I have published my AJAXised web application to the server and the application failes to work properly - something weird is going on, as all .aspx pages are displayed as an ASPX markup text (page declaration, html controls, etc.), rather than a page is being rendered as an html. I have not changed the webconfig, only changed my pages' content/code behind.

AJAX :: TextBox Value Not Being Updated From Code-behind?

Apr 21, 2010

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.

Hidden Field Not Retaining Value When Updated From Code Behind?

Feb 14, 2011

I'm using a hidden field to store a value in an page. Basically I set the value of the hidden field whenever a value on the form is changed i.e. first name, date etc. The field is on a webform that has a master page and is in the content section:

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<asp:HiddenField ID="hdnDirtyFlag" runat="server" Value='false' />

I change the value of the field in javascript by calling a function whenever an onchange event fires in other controls on the web form:

<asp:TextBox CssClass="niceInput" ID="tbFirstName" runat="server" MaxLength="40" Width="150" onchange='SetHiddenVariable();'></asp:TextBox>
<script type="text/javascript">
function SetHiddenVariable() {
// Set the value of the hidden variable so we know a field has been updated
var hiddenControl = '<%= hdnDirtyFlag.ClientID %>';
document.getElementById(hiddenControl).value = 'true';

So far so good. When the page loads the hidden field value is 'false', and if I don't change any values on the webform it remains false. Whenever I do change another control the javascript function gets called and the hidden field value gets updated to 'true'. Again this is all fine.

After I submit the form and update the database, I set the hidden field value back to 'false' in the code behind:

hdnDirtyFlag.Value = "false";

But when I click another button and do a postback, the hidden field value is still at 'true'.

Can anyone explain why this is? I stepped through the code behind and immediately after changing the value I can see the value is 'false'. There is an asp:UpdatePanel on the page but the hidden field is not part of this panel.


This is the code I use to check the value of the field in code behind in the second postback, after it has been set to false in the last step of the first postback. The value remains at true for some reason in the second postback, after it has been set to true in javascript on the client side then set back to false in code behind as shown above:

if (hdnDirtyFlag.Value == "true")

Combobox / Textbox Was Changed By The Code Or The User?

Apr 13, 2010

In a form control i have a listview and some textboxes and comboboxes.

When a list item is selected i add the data to the textboxes so the user can change them. non of it is databound. all the changes are made in the code.

I wanted to know the best way to find out if i the checkbox_SelectedIndexChanged event was triggered by the code behind or the user. is this possible through either the sender object or EventArgs. i didnt want to have to set bool values or something like that every time i change the values from the code. prefer a solution where i only have to add code to the checkbox_SelectedIndexChanged() method.

NB: the initial use for this is just to enable a save and cancel button (without having to remeber and compare values). There will be other uses for this later on as well.

Web Forms :: UserControl Value Is Not Changed When Written Through Code Behind?

May 3, 2010

i have one user control which has hiddenField name ='hdnShow' as runat='server'

my scenario is that i have a function in userControl name Show(MessageType);

void Show(MessageType msg)
case MessageType.Success:hdnShow.Value= "Success fully saved";


when i execute it and tries to get value of hiddenField thru javascript it still predicts the initial value.

Strange thing is that when i make a textbox in webusercontrol and then try to set its value thru this function.

even the textbox value don't change we can see it on aspx page that value is still the initial one.

some site has asserted that we can do that thru preRender event but it is not working.

may be it is happening coz it is in updatePanel??

yeah i have tried EnableViewstate true and false both condition.

Custom Server Controls :: Visible State Of The Div Is Changed In Client Code W/o A Postback?

Mar 11, 2011

In ASP .NET 2.0, I've created a user control which is meant to work as a dropdown or popup by using an <input type="button" id="btnTogglePopup" runat="server" style="display:inline"... /> and <div id="divPopup" runat="server" style="display:none" ... /> the rest of the controls are contained inside this div, and they do mantain their values between posts, etc. This button 'runs at server' but it's not intended to post back or submit.It just toggles the popup (div) visible/hidden using Javascript client code by setting the div's style display property to "none" or "block" The problem I'm having is that when a page containing this control posts back, the state visible/hidden of the div is not maintained. If the user had the popup open, after the postback, it will display closed.I've read a bunch by now about ViewState & ControlState, and have the save and load contol state methods working, but when I step thru them they load old values (setting the popup to hidden all the time),and the popup doesn't work! I've come to think that b/c when the button is clicked,the visible state of the div is changed in client code w/o a postback, maybe I have to maintain this state info in a hidden fiel or something like that?At the same time I don't want to have a hidden field if it's unnecessary,and I may just doing something wrong.

Html Literals In MVC3 Model Code?

Mar 24, 2011

I have a RegisterModel view model I use for my new account registration page. Depending on the status of a registration task, the model has a relevant text message to display for the user, e.g. "Waiting for email confirmation" etc.

I currently populate this string property in the manner below, but couldn't help wondering about mixing markup and content like I do with the <p> tags. Is there a better or more accepted way of doing this, besides having multiple partial views with actual HTML literals instead of model properties?

RegisterMessage = "<p>Please use the form below to create a new account.</p>";
RegisterMessage = string.Format("<p>Passwords are required to be a minimum of {0} characters in length.</p>", _membershipService.MinRequiredPasswordLength);

EDIT: I have just noticed that the <p> tags are rendering literally, but I doubt that issue falls under the same question.

SQL Server :: Row Not Found Or Changed - Only When Field Is Changed To Something Else Then 0

Sep 14, 2010

For our ASP.NET project for school we had to build a sport event management web application.

We provide the application in three languages (English, Dutch & French) which you can switch all the time. This has worked all the time for all users, well that's what we think anyway.

Yesterday I found out that switching from one to another language isn't working for 2 of our users. So I started testing a bit and I always got this error.

I'll try to explain what happens behind the doors when changing the language:

First of all the current language is saved in a session so we don't have to check the user row every time a page loads. Besides that we save the language in the users row in the database.

Users Table:

Id int
Email varchar(150)
