I would like to locate the new record in a paged list after the record is inserted to the database. Say there are 10 pages of records. Each page is size of 20 records and sorted by last namez of people. I add a new record with last name Murray. Using MVC, how do I position to the page where Murray is after a post back? The controller's New action return to Index view, but it always return to the first page.
1. How do I make the Index method or some other method to go to page where newly inserted record is.?
2. How do I make the browser scroll to the row where the newly inserted record is in a NON-paged list?
I need to access a TextBox control inlistview. I have tried the following code behind but I don't retrieve the correct textbox. A snippet of the code is as follows:
I'm very new on VWD, but I got the hang of it for the past 2 weeks(thank you for all the videos posted here in ASP.NET),but I'm really weak on the coding part(vb & c#),except for all the sample shown on the tutorials. Anyways, I have a simple project that does insert, update & delete to SQL express using the details view. But to complete my project, I need to add a button that will create an event to restore the very last record inserted in SQL and display it back into the details view for minor modification and nserted again as the newest record with the mod. I'm doing this so user, doesn't need to re-key-in redundant information, like names, original date & time etc, and just make modification on the description of the last record.....
I use GridView & FormView to update a record. but when I click the "save" button, throw an except : FormView must be in the insert mode to insert a record. The record has been updated success, and I didn't change the mode of the FormView, how this error comes?
Conseptually what I'm doing is simple, and technically it may even be simple, but I'm still rusty. Here's what I'm trying to do:
I have a webform that allows the user to enter a new record, and in there I have also included a couple FileUpload controls. Upon clicking the "Save" button, I'm saving the details entered into one table (ITEMS), and also inserting the FileUpload details (path, id, upload_user) into another table ATTACHMNTS). Because one ITEM can have many attachments, I needed to split the tables up. So on save, I need to save the ITEM, save the ATTACHMENT, and then also put the ITEM_ID in the ATTACHMENT table. I'm second guessing myself because I think all I'd have to do is after I do the ITEM insert, do a SELECT MAX on the ITEM table and hold the newest (MAX) id in a variable and then use it in the ATTACHMENTS update. I'm not 100% on this because there IS a chance that someone else could save a few milliseconds later and I'll link the wrong ITEM. See my delima?
I have written a script to write several values to an Access Database Table, but I need to ammend i so it checks for two values (Asset and LName) to see if they match if they do it updates the record if not it writes a new record, my script so far is as follows :

I'm just stuck as I can't work out the best way to do it,
I have a dropdownlist that is populated with a staffID number depending on the staff members name that is selected from a second dropdownlist. The value from this dropdownlist is then inserted into a new record when the page is submit using the InsertQuery of an sqlDataSource.
I'm very new to this area and am using ASP.NET 3.5 with WMD 2008 Express Edition and VB code.

My website is a Rugby Club site and I've an SQL database of match fixtures which include TeamId(1XV, 2XV, etc.), Season(2008, 2009, etc) and match date.
I allow some users to update the fixture details but want to insert a series of new fixture records for the neext season which contain just TeamId Season and Match Dates. I therefore want to take the season and Team Id from label fields and then create match dates by adding seven days to a start date.
the problem is that it will insert a new record in a mysql table, I have already done the mapping of the mysql db and I have already done tests returning data and everything works. Now I read from a file, where there are queries written, I have them run me back and the result of true or false based on the final outcome of single query written to the file. Txt; I did this:
using (var w = new demotestEntities ()) ( foreach (var l listaqueri) ( var p = we.CreateQuery <category> (l); we.SaveChanges (); result = true; ) )
but it does not work, I sense that it returns no errors, but neither the result given written in the query. txt file is as follows: INSERT INTO category (id, name) VALUES (null, 'test2')
I want to check if the record is already exists before insert using Ajax ActionLink in Create View. I am getting error 'Object reference not set to an instance of an object.' Here is a code in View :
<div class="editor-label"> <%= Html.LabelFor(model => model.PolicyId) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.PolicyId) %> <%= Html.ValidationMessageFor(model => model.PolicyId) %> <em>can not be changed later.</em> //error occurs here <%= Ajax.ActionLink("Check", "CheckIfExists", "Life", new { PolicyId = Model.PolicyId }, null)%> </div>
And Controller action :
public JavaScriptResult CheckIfExists(string PolicyId) { if (lifeRepository.IsExists(PolicyId)) return JavaScript("alert(' Already Exists');"); else return JavaScript("alert(' Not Exists');"); }
I use the following code to insert recode to a sql 2008 table, the field ID of DBProgram is IDENTITY, so SQL 2008 SERVER will pass a value to it automatically. How can I get the ID value of the record I just insert ?
DBProgram dbProgram = new DBProgram(); db.DBPrograms.InsertOnSubmit(dbProgram); db.SubmitChanges();

I am designing a social networking site that has a "wall" feature like the others out there today. The database has an alerts table that stores some user action worthy of sharing with his friends. For example, when a user updates his status, all of his friends are notified. The below table shows two status updates from two unique users. The first (AlertId 689 and 690) is submitted by AccountId 53. Since he has one frinend - AccountId 57 - that row is added to the table so when this user logs on, he will see Account 53's update on his wall. In the same manner, the other user's status update has four rows because he has three friends.
[AlertId] [AccountId] [CreateDate] [Timestamp] [AlertTypeId] [IsHidden] [Body] 689 57 2010-08-10 0x0000000000018725 10 0 HTML 690 53 2010-08-10 0x0000000000018726 10 0 HTML 691 53 2010-08-10 0x000000000001872B 10 0 HTML 692 52 2010-08-10 0x000000000001872C 10 0 HTML 693 51 2010-08-10 0x000000000001872D 10 0 HTML 694 57 2010-08-10 0x000000000001872E 10 0 HTML
Now, a user can comment on any given item, in this case a statusupdate. When AddComment is submitted, we are using ObjectRecordId (which is the primary key of the alert being commented on) in order to identify which statusupdate is being commented on (fyi - the objectId tells us its a statusupdate):
public void AddComment(string comment) { if (_webContext != null) { var c = new Comment { Body = comment, CommentByAccountId = _webContext.CurrentUser.AccountId, CommentByUserName = _webContext.CurrentUser.UserName, CreateDate = DateTime.Now, SystemObjectId = _view.ObjectId, SystemObjectRecordId = _view.ObjectRecordId }; _commentRepository.SaveComment(c); } _view.ClearComments(); LoadComments(); }
Now, the problem is that when a user wants to comment on a friend's status update, he will be using the AlertId (or ObjectRecordId in the Comments table) corresponding to his account in the alerts table. The result is that comments are only viewable by the commenter and none of his friends:
Of course the solution to this is to do something similar to what I did in the alerts table - when somebody makes a comment, make a corresponding row for every friend in the comments table. But how do I access the AlertIds of all of my friend's status updates in the Alerts table and map them to the ObjectRecordId column in the comments table? Since I can only access the status updates corresponding to my account (and their corresponding alertids), I don't know what the alertids are for the same statusupdate in my friend's accounts.
I have a scenario in which the user can add a new option to appear in the list of available choices in a DDL contained in a detailsview when they select an option <Add New>. This displays an AJAX model popup which then allows the user to enter the new option text. Then they hit an Insert button which inserts that new option into the DDL's datasource and I call ddl.DataBind. Subsequently I want to close the modal popup and then display the newly created DDL option as selected.
When I step through the code, everything appears to be working as expected...i.e. the DDL's datasource now has 1 more record than before and the ddl.SelectedValue is the newly created record for its datasource. I can also query ddl.items(99) and see the new option is part of the ddl's items collection and the new record is Selected.
HOWEVER, once the screen comes back from the debugger, the DDL is now showing the newly created option, but still the prior selected option of "<Add New>". And if you pull the DDL down the newly created option is not in the list?
I cannot figure out how that happens...though I suspect it has something to do with the AJAX/Update panel. Here's some code:
