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)

The following references to user controls give the error "Row not found or changed." However, when I remove any one of the references, the results are perfect and everything displays fine.

Row Cannot Be Found Or Changed?

Mar 19, 2011

When I try to Update or Delete a single selected item, it throws a "Row not found or changed." exception. Basically I only did a linq query and use most of the auto-generate function. I added LinqDataSource1_ContextCreated function,

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
AutoGenerateDeleteButton="True" AutoGenerateEditButton="True"
DataSourceID="LinqDataSource1" Width="100%"
<asp:BoundField DataField="JobId" HeaderText="JobId" ReadOnly="True" />
<asp:BoundField DataField="JobTitle" HeaderText="JobTitle" />
<asp:BoundField DataField="Summary" HeaderText="Summary"/>

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.

C# - System.Data.Linq.ChangeConflictException - Row Not Found Or Changed

Feb 2, 2010

I wasted the better part of the day on this and am no closer to a understanding the issue than what I was this morning.

I am looping through a set of objects and marking them for deletion. The 2nd one always causes the above exception. tb_invoice has a FK to tb_shipment.

As always, I am probably missing something very obvious, but I have stripped out so much from this code already that there is nothing left, and I am still getting this exception. This is a local SQL 2008 instance and there is of course nothing and nobody changing the invoice in between reading them and calling SubmitChanges().

myDataContext db = new myDataContext();
IQueryable<invoiceDetail> pendingInvoices
foreach (invoiceDetail id in pendingInvoices) {
tb_shipment s = db.GetShipmentById((Guid)id.shipment_id);
db.GetInvoiceById(s.tb_invoices.FirstOrDefault().id)); }
SubmitChanges(); // fails for the 2nd invoice

Ways To Detect Changed Account / No Account Found In C#?

Oct 15, 2010

I have an ASP.NET page where at the top of the page is a search box. There are 2 text boxes - one is an autocomplete extender for the Name on a database, and one is just inputting the ID.The page features DetailsViews and GridViews primarily, and even when no account has been searched for, these display blank data which is not ideal. I sort of fixed this by using if (IsPostBack), encasing the elements in a placeholder and setting it to visible only if the page ispostback. But this doesn't cover if the user types in an incorrect ID.

Also, some accounts have huge amounts of data inside the GridView's. I had an issue where because I have no way of detecting when a data source's rows has changed, I end up binding whenever the page loads (Page_Load method). I've come to realise this is simply very bad - there are lots of times when the user can click various things in the page and have the page postback, and it takes an eternity to load each time I click something for accounts with lots of data.Anyway, my question is essentially two-fold but I have a feeling the solution will be similar:1: How can I detect when there are no accounts returned when searching, and disable the Grids/Detailsviews and show an error message?2: How can I figure out when the user searches for another account and only rebind the grids after that has happened?

C# - SQL Server - Refreshing Cached DataTable With Only Records That Have Changed

Jan 20, 2010

I have a large DataTable cached in my web app that is the result of a complex query that returns a large data set. Whilst this data table is cached the query that runs to "refresh" this cache still takes a long time, largely due to the sheer amount of data being returned. In order to speed this up I am considering implementing a timestamp type approach to my tables in order to limit my query to only return rows which have changed.

I then intend to merge this smaller dataset with my cached datatable. Has anyone done anything similar to this, or is there anything out there that handles this already? I feel this could be a re-inventing the wheel situation if I dive straight in.

C# - Change Span Only When Sql Server Table Changed - Ajax 3.5 Jquery

Mar 27, 2011

I have asp.net label called NumberLabel.It is changed from codebehind(asp.net/c#) by calculating the number of rows in an sql server table called "MyTable". Every time a user open this page,the same code/stored procedure is executed to bring the number. Is there a way to to bring the same number for all users and change it only when there is an update in "MyTable".this will optimize a lot time,executions,(SQL server side and webserver side).Does asynchrounous c# exist?or doing that by ajax.

State Management :: Server-side Detection Of A Changed Form?

Mar 7, 2010

I've searched high and low for a efficient and reusable way to detect, on a postback/server-side, if any input controls on a form have been changed and I haven't found anything other than client-side solutions such as DirtyUpdatePanelExtender. I've come to the conclusion that it must be either really simple or really complicated.Ultimately what I want to do is to perform a database update, or not, depending on whether or not the user has changed any input controls on the form. The only thing I've come up with so far is to save the original values as Viewstate variables and then compare them with the Request values on a postback, but that seems far from ideal.

Web Forms :: Display Server Side Yes No Confirmation Box On DropDownList SelectedIndex Changed

Apr 29, 2014

 I am trying to use Yes No Confirmation Message Box but the code below here which i found here uses a button to raise the confirmation message box but what i would like to use is a DropDown.  How can i modify the code and i use drop-down box instead of using a button? here is the javascript code: 

<script type = "text/javascript">
function Confirm() {
var confirm_value = document.createElement("INPUT");
confirm_value.type = "hidden";
confirm_value.name = "confirm_value";


but here is what i would like to use is drop-down instead of the button:

<asp:DropDownList ID="ddl" Width="300px" runat="server" AppendDataBoundItems="true" OnSelectedIndexChanged="ddl_SelectedIndexChanged">
<asp:ListItem Text="test1" Value="test1"></asp:ListItem>
<asp:ListItem Text="test2" Value="test2"></asp:ListItem>

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.

SelectedIndex_ Changed Not Getting Fired?

Oct 22, 2010

SelectedIndex_Changed event occurs when selection changes, and selection is changed or not is decided by comparing dropdowns current selectedIndex and its value in viewstate.

When we changes dropdown's selected Item using Javascript, it does not change the viewstate's value (which is previously selectedIndex). Now if you change dropdown's selectedIndex to any new index it will work fine, but if you select the previously selectedIndex (which we reset using javascript), then postback will occur, but selectedIndex_changed function will not get fired because in viewstate of dropdown, selectedIndex is same as the Index we select after resetting it using javascript.

using asp.net you could create a listbox_valueChanged event and handle the user selection inside the event handler. How could i implement such a functionality using asp.net mvc? I guess that the best way could be to use ajax techniques in order to manage the user selection on the client side.
