SQLDataSource Or SqlAdapter

Mar 12, 2007

Ok... this might seem stupid question but....

When to use each on ? I know SQLDataSource is pretty easy and straightforward, and its a pretty cool web control to use as Datasource for Grids and other web controls...

But everything can be done in SqlAdapter  can't it? If it can... Then i'd rather prefer to do everything manually even If im not taking full advantage os such new controls for 2.0, but its a bit "too automatic" for me, yeah.. guess its all on saving time and productivity.

 Anyway, can everything get done withouth the need of SQLDataSource? Say I want to create a Gridview that allows you to update rows, with a SQLDataSource  its pretty easy as you just stick in a parameter like ...

 UpdateCommand="UPDATE table SET name = @name" 

How could I do this with SqlAdapter and then apply to a Gridview... ?

 Thanx in advance!

SQLAdapter Update And Datetime

Mar 13, 2008

Hey,

I have a case where I fill a datatable with two column wich contain
datetime. Il filled them and everything seems alright in debug. Problem
is that when I update with the SQLAdapter, it says that it cannot
insert NULL into a datetime column, but the fact is that it is not NULL.

Here what it looks like:

SqlConnection conn = new SqlConnection(ConfigurationManager.AppSettings["BD"]);

conn.Open();



adapter.InsertCommand = new SqlCommand("Commun.SP__PeriodeEnregistrer", conn);
adapter.InsertCommand.CommandType = CommandType.StoredProcedure;
adapter.InsertCommand.Parameters.Add("@idperiode", SqlDbType.Int, 10, "IDPeriode");
adapter.InsertCommand.Parameters.Add("@nosemaine", SqlDbType.Int,10,"NoSemaine");
adapter.InsertCommand.Parameters.Add("@annee", SqlDbType.Int, 10, "Annee");
adapter.InsertCommand.Parameters.Add("@periode", SqlDbType.Int, 10, "Periode_no");
adapter.InsertCommand.Parameters.Add("@datedebut", SqlDbType.DateTime, 150, "Debut_date");
adapter.InsertCommand.Parameters.Add("@datefin", SqlDbType.DateTime, 150, "Fin_date");
adapter.Update(dtPeriode);

Thanks in advance

Count Records In Sqlcommand Or Sqladapter?

Apr 13, 2007

Hi everyone? I have a small problem here, I want to count the records found under the following method:  Public Function ValidateAssembly(ByVal assyno As String) As DataSet

Dim SQLConn As SqlConnection = New SqlConnection(Connstr)
Dim adapter As SqlDataAdapter = New SqlDataAdapter
Dim dsVendorInfo As DataSet = New DataSet("AssemblyHeader")

Dim cmd As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand

Dim BMItemno As New SqlParameter("@v_assyno", SqlDbType.VarChar, 10)

BMItemno.Value = GetBomAssyNo(assyno)

SQLConn.Open()
Try
With cmd
.CommandText = "SELECT * FROM dbo.cfn_bom_get_assy(@v_assyno)"
.Parameters.Add(BMItemno)
.Connection = SQLConn
.CommandType = CommandType.Text
End With

adapter.SelectCommand = cmd
adapter.Fill(dsVendorInfo)

Catch x As Exception

End Try

SQLConn.Close()

Return dsVendorInfo

End Function I want to see if this can be done and passed to the actual dataset? Is this possible? Or do I need to pass the found results from my query to a sqlreader? Also, Im I forced to put my colums together in a DataTable before actually binding to the DataSet? Thanks everyone!

SELECT A Single Row With One SqlDataSource, Then INSERT One Of The Fields Into Another SqlDataSource

What is the C# code I use to do this?
I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.

Sqldatasource

Jan 15, 2007

hi all,
in all my 2.0 learnings and books i keep coming across the page element <asp:sqldatasource>.
I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed.  Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data.  Can someone explain the benefits of using this data source?  Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular.
thanks in advance,

Using SQLDataSource

Feb 23, 2007

Hi, I am new to ASP.NET 2.0 and I am trying to use VWB to bind my web site to a SQL Express edition. I used SQLDataSource to specify the .mdf file so I can connect to my tables but when I click on the advanced button to generate the Insert, Update, Delete SQL I find it grayed out and it cannot be clicked. I looked into several tutorials online and I couldn't find the problem, can anyone explain what I am missing or doing wrong? Any suggestion is very appreciated. Thanks

Using An SQLDataSource For Than Once

Aug 21, 2007

Hi,
I'm trying to go through a checkbox list and inserting them into a database using a sqldatasource with the following code:For Each li As ListItem In Locations_Checkbox.Items
If li.Selected = True Then
 
Dim DataSource2 As SqlDataSource = CType(InsertProgrammeLocations, SqlDataSource) DataSource2.InsertParameters.Add("ProgrammeID", li.Value)
DataSource2.Insert()
 
 
End If
Next
When more than one checkbox is ticked, I'm getting the error 'The variable name '@ProgrammeID' has already been declared'. How do I close or reset my Datasource before I try and use it again?
Thanks for your help

What Is SqlDataSource

Oct 29, 2007

Hi, I want to know when to use an sqlDataSource object because I used to populate for example a listBox control in visual studio net 2003 from AQLK server database by using a connection object, command object, dataAdapter object and a DataSet object. I discovered if I use sqlDataSource object (using visual studio net 2005) ,all I need is to write the connection string and a Select statement as properties for that sqlDataSource, so why to use the above mentioned objects(connection,command,adapter,dataset) while I can access any database in sql server through the use of sqlDataSource?
I appreciate if you can explain to me the difference and when to use an sqlDataSource
thx

Do You Really Use SqlDataSource?

Dec 9, 2007

Hi,
I have an application w/ n-tier design so I've never used the SqlDataSource up to this point but having to do my own sorting for GridViews is not something I want to keep dealing with. I'd like to take advantage of some of the packaged features too.
My question is: are there any purists out there who opted to use SqlDataSource. If so, what do you think about it? It's nice that SqlDataSource makes things simple but having data classes and dealing w/ exceptions in those classes certainly make an application pretty robust. Should I entertain the idea of using SqlDataSource or stay as a purist and keep doing things the old fashioned way?

SQLDataSource && ADO.Net

Apr 16, 2008

Could someone help me with syntax?  Everything works until line 23.  At that point, I get a NullReferenceException.  When I examine the SqlDataSource object, everything inside reads "Object cannot be null" or "The pointer for this method was null."  The SQLDataSource looks ok, just before executing line 23.
Does anyone have a complete example of how to do this ADO operation?
Thank you. 1 Dim fv As FormView = Nothing
