DataSource Controls :: Update Only Changed Or Insert New Rows In Datatable?
Mar 4, 2010
Existing records can be updatedNew records can be insertedAll existing records can be deleted & new ones can be insertedExisting records have a primary key field
New ones are just blank inserts
All this detail is stored in a data table. On form update I only want to update existing (only modified rows) & insert new rows. I have gone about loading the changed records in a new data table
DataTable changedRecordsTable = dataTable_old.GetChanges();
How do I compare it with all the records in the old datatable and pass them to the save query ?

I am using untyped database bind to gridview in an edit form. Now user makes some changes to that datatable (update, delete, insert). How do I detect which rows he changes and which rows he deleted (so I drop them from DB). I know it can be done easily via table adapters but I am supporting a previously built app using untyped datatables/datasets.

I'm trying to add new rows to a data table and then use the sqldataadapter update method bu fund some problems. First, I written this code:
[Code]....
Excuse me but the most part of variable are in italian, however I think it is possible to understand how does it work. If I execute this code I obtain this error:
System.InvalidOperationException: Update requires a valid InsertCommand when passed DataRow collection with new rows.
After this I added these lines of code just above the last line:
SqlCommandBuilder cb = new SqlCommandBuilder(adapter);
adapter.InsertCommand = cb.GetInsertCommand;
and I obtained this error:
Cannot convert method group 'GetInsertCommand' to non-delegate type 'System.Data.SqlClient.SqlCommand'. Did you intend to invoke the method?

I have created a datatable with three fields namely TimeTask, TaskItem and Count (count of user) eg; {"12:30AM-01:00AM" , T1 , 3}.
dataTable.Columns.Add("Task Time", typeof(string));
dataTable.Columns.Add("Task", typeof(string));
dataTable.Columns.Add("Count", typeof(int));
dataTable.Rows.Add("12:00AM-12:15AM", "T1", 6);
dataTable.Rows.Add("12:45AM-01:00AM", "T1", 5);
dataTable.Rows.Add("01:00AM-01:15AM", "T1", 1);
dataTable.Rows.Add("01:15AM-01:30AM", "T2", 4);
dataTable.Rows.Add("01:30AM-01:45AM", "T2", 9);
GridView1.DataSource = dataTable;
GridView1.DataBind();
In this there is no task for the TimeTask "12:15AM-12:30AM" and "12:30AM-12:45AM" yet the TimeTask should be inserted as,
TimeTask TaskItem Count
12:00AM-12:15AM T1 6
12:15AM-12:30AM - -
12:30AM-12:45AM - -
12:45AM-01:00AM T1 5
01:00AM-01:15AM T1 1
01:15AM-01:30AM T2 4
01:30AM-01:45AM T2 9

I have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).
What is the best and fast way to do it?
I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?
I'm also looking for example in code how to select/delete rows from DataTable.

Here a samplescreenshot:

I know how to bind the columns to a grid and its no problem to create such a dropdown list with the content for me, too. But i dont know how to sort the complete datatabl after changing one value of one dropdown listbox.
So, how can i resort the values of a datatable column based on a given value and the datarow id?

I've got a GridView in which all rows are set to Edit by default.
I want to be able to save the rows only where changes have been made. At present, my code will only update the first row from my GridView to my database. I've had a look on the internet, and think that the Getchanges might be able to help me, but I'm struggling to work our how exactly to implement it in my scenario.

Maybe this could be a simple questino, but for me it's difficult to do this action: I have a table in sql server 2005 with some records stored, for example 10 records. The primary key of this table, let's call it "Employee", it's a number field with an autoincrement constraint. I want to store more data into the table by using a OdbcDataTable object and OdbcDataAdapter and adding new rows to the datatable and afeter that use the "Update" method from the OdbcDataAdapter object.
The big deal is this: let's suppose that I want a add a new record to the datatable object, using any method or code sequence that you want. if I have 10 records stored on the data base table, when I retrieve this table schema by using the OdbcDataAdapter "Fill" method, I have a copy of the data base table schema in the DataTable object, right?. if I add a new row on the datatable object, it's suppose that the primary key column of that table must AUTO-INCREMENT the value of the key, I mean if the last value that I store on the table was the number 10 on the PK field, when I add a new row on the datatable object, the PK value on the datatable object must be the number 11 if the autoincrement constraint is present into the DataTable object, but in my case, it doesn't work
So, How can I define the conditions or set the c# data objects properties to wor in that way???. In this moment the PK column on the odbcDataTable doesn't auto-increment its value when I add a new row on it.
Please helpe with this.
PD: I have another question about the DataTable object, how many records can store this object?? I have some problems with this because sometimes when I use the Fill() method to get data into the DataTable or a DataSet object there's no problem if the Fill() method retrieves about 142000 records, but when I retrieve over the 145000 records, when I inspect the DataSet or DataTable object by using the debuging mode, they have null value. Any of you can tell me why this situation ocurrs??

I have one problem with my shopping cart that I really can't figure out all by myself.I want, if a item already exist in the datatable, the quantity to be updated for that item with the new number instead of creating the same item again.I have done a foreach loop because I think that is where I should start.Notes: MyRow[3] is the column holding the quantity.Code:

I am using 1 textbox with a Ajax Calendar extender to allow my user's to select a date graphically (exp: 12/15/2009). I have another textbox for the hour and minutes in military time(exp: 15:30). I think i have the code to grab the data from the 2 textbox's and combine them to be inserted into the field (exp: 12/15/2009 15:30). Here is my insert code for the Field:
[Code]....
However unless I make all the fields Nullable the insert fails, on top of that none of the other field that I have selected on the Detailsview Insert or Edit are inserted into there fields. Half of my fields have to be non-null values. So how do I fix this?
I can supply additional vb code and the aspx code if needed.
This is the error I'm getting: Cannot insert the value NULL into column 'Operation_type', table '/GAOSDB.MDF.dbo.BC_Perf_Log'; column does not allow nulls. INSERT fails. The statement has been terminated.'
This is the first non-null column.
I need to get this figured out because I have 30 other web pages that will be utilizing the same approach.

I want to delete the rows present in the DataTable by using LINQ (with out looping)
The deleted rows will be come from a LINQ as below
IEnumerable<DataRow> MobileQuery = (from d in dtBillDetail.AsEnumerable()
where (String.Compare(d.Field<string>("Destination"), "MOBILE", StringComparison.InvariantCultureIgnoreCase) == 0) select d );
The DataRows present in the "MobileQuery" should be deleted in the DataTable "dtBillDetail"

I'm trying to figure out how to update multiple rows in my Directory table, when a user changes their Street Number or Street Name in their profile. They can add multiple users to a directory and each user they add to the directory has this primary users UserId in it. So if the primary user changes their address, I want it to update the address for all the users they listed in the directory as well. I'm adding this to the On_Click in the Code Behind, so when they click to update their profile, it fires this function as well. This code may be way off, but here's what I have right now:

I wrote in subject "Is there any way to UPDATE multiple rows WHERE UserID = @UserID_ArrayList" For example I have an Arraylist like this:
Dim UserID_ArrayList As New ArrayList
UserID_ArrayList.add("100")
UserID_ArrayList.add("150"
UserID_ArrayList.add("200")
Now I have to UPDATE some columns inside those 3 records WHERE UserID = @UserID_ArrayList I'm sure it can be done somehow?

I used to ADO.NET+DataSet many years ago, but now, I need it again. So what I need is to add related rows with tableAdapter.Update method.Here is my code: [Code]....
but I get the "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Question_Project". The conflict occurred in database "QTracker", table "dbo.Project", column 'ID'. The statement has been terminated." exception at the "qTA.Update(ds);" row. I have seen many examples that do the same, but my code still throws the exception.

Not sure where I went wrong with this one, but I can't figure it out now... I've got a DetailsView in an UpdatePanel. A dropdownlist controls which person's details are displayed in the DetailsView. I have the DataSource set to an ObjectDataSource, which has select, insert and update methods defined. I also have a method for the ItemCommand, ItemInserting, ItemUpdating and DataBound events of the DetailsView specified.
When I click "New" or "Edit" on the DetailsView I get the open form with either the details for the current person, or a blank form, exactly as I would expect. But when I click the "Update" or "Insert" buttons it does absolutely nothing. I have it running in debug, and have put breakpoints in the ItemCommand, ItemInserting and ItemUpdating methods, right at the top, and it never goes there. The form remains open, and nothing happens. If I click "Cancel", it posts back and goes back to ReadOnly mode.
A couple more minor details that may be important: This page is using a Master page, which is where the ScriptManager is. I'm actually using the ScriptManager from the AjaxControlToolkit. I also have a GridView in this same UpdatePanel, and that has a FileUpload control in it. Because the FileUpload control doesn't work properly without some tweaking, I have to call a RegsiterPostbackTrigger method on page load to link it back to the Master page's scriptmanager. Not sure if that's causing any issues...?
I had this working fine, but then as the page got more complex and I had to change some of the code, at some point it just stopped working and now I can't figure out how to get this working again... I'm happy to post code if necessary, just thought I'd try this first to see if anyone has a quick idea for what to check.

I have a web project with more than 100 input boxes , so in every INSERT and UPDATE to sql server in front of sql statement I must put the golden N word, so it will be in UNICODE mode. Do we have some alternative of this? How can i make it in EVERY UPDATE and INSERT to sql server in data layer level- make it like u insert UNICODE (without N word) How can you get MSSQL server to accept Unicode data by default into a VARCHAR or NVARCHAR column?
I know that you can do it by placing a N in front of the string to be placed in the field but to by quite honest this seems a bit archaic in 2008 and particuarily with using SQL Server 2005. Example:
cmd = New SqlCommand(sql, ConnectionFromEnum(whichDatabase))
cmd.Connection.Open()
i = cmd.ExecuteNonQuery()
so....
the question is : Am I suppose to make something with SQLCOMMAND to set- "enter evthng like it is UNICODE, with N auto"? or i must specify UNICODE by default in somewhere else? just to indicate that i already set in web.config
<globalization requestEncoding="utf-8" responseEncoding="utf-8" fileEncoding="utf-8" responseHeaderEncoding="UTF-8" culture="en-GB"/>
So global questions HOW TO MAKE INSERT AND UPDATE Unicode by default in every insert and update methods, without placing N word in front of literal string?

Is there a way to create a contact form that takes the name. address and other info for the master record; Then, somehow, on the same page, allow the user to enter multiple contact info as chid records (i.e. phone, email, etc.)
All this using the Objec DataSource or SQL DataSource (which ever is easy) and doesn't require writing too much code.
