DataSource Controls :: Use An ObjectDataSource Update Method With A Table - Valued Parameter?
Oct 13, 2010
I'm trying to figure out if it's possible to use an ObjectDataSource Update method with a table-valued parameter. Here's my ODS:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
DataObjectTypeName="TestProject.MyTestDataTable"
SelectMethod="GetTestData" TypeName="TestProject.BLL.TestBLL"
OldValuesParameterFormatString="original_{0}"
UpdateMethod="UpdateTestData">
<SelectParameters>
<asp:Parameter DefaultValue="65" Name="testId" Type="Int32" />
</SelectParameters>
</asp:ObjectDataSource>
I bind this to a GridView but I'm not looking to edit row by row. Instead my GridView has a bunch of TemplateFields with textboxes. I also have a Button that when pressed, invokes the Update method of the ODS. So then the "UpdateTestData" function in my TestBLL is called. This looks like this:
public void UpdateTestData(MyTestDataTable dt)
{
QueriesTableAdapter qta = new QueriesTableAdapter();
qta.UpdateTestData(dt);
}
At run-time in debug, it seems like the object for the signature above is not populated with the data from my GridView.

I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):
Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating
Dim entity As New Login()
Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo)
entity = accountControl.Entity
e.InputParameters.Add("entity", entity)
End Sub
And here's the markup for the datasource:
<asp:ObjectDataSource ID="MasterDataSource" runat="server" EnableCaching="true" CacheDuration="10"
SelectMethod="SelectAll" UpdateMethod="Update" TypeName="Data.DAL.LoginDAL">
</asp:ObjectDataSource>
My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:
Public Overloads Function Update(ByVal entity As Login)
If entity Is Nothing Then
Throw New ArgumentNullException("entity")
End If
MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _
entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax)
End Function
When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the
last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?

If an ASP.NET web page uses an ObjectDataSource, can you configure it to use a stored procedure that uses table-value parameters?
User-defined type:
CREATE TYPE [dbo].[integer_list_tbltype] AS TABLE
(
[n] [int] NOT NULL,
PRIMARY KEY CLUSTERED
)
Stored procedure:
CREATE PROCEDURE [dbo].[GeneralReport]
@intList integer_list_tbltype READONLY
AS
BEGIN
SELECT * FROM ...
END
ASP.NET
<asp:ObjectDataSource ID="GeneralDataSource" runat="server"
SelectMethod="GetDataByRange"
TypeName="MyProject.GeneralDataSetTableAdapters.GeneralViewTableAdapter"
>
<SelectParameters>
<asp:Parameter Name="intList" />
</SelectParameters>
</asp:ObjectDataSource>
I've tried hooking into the ObjectDataSource's Selecting event like this:
[code]....
be set for UDT parameters." being thrown

Here is the "Update" method which is not updating.
It works if I remove "@original_UnitPrice" and "@original_OnHand" parameters from the "WHERE" clause.

This is my first attempt in using table valued parameters in my stored procedures. Please find the scripts down below. The idea is very simple. I'm trying to insert a new product into Products table and if the product has attributes, I'll insert them into ProductAttributes table which is where I use table-values parameters.
I was able to test the stored procedure manually. It's working fine. So the error must be in the C# code but there's not much to it.
Here's the DAL code in C# that calls the stored procedure:
[Code]....
Just in case you need it, here's what my Product object looks like:
[Code]....
And the ProductAttribute object is even simpler:
[Code]....
Here's the SQL scripts to create the tables, stored procedure and user defined table type:

I would like to know which one is better, table-valued function or View, in terms of perfomance.Earlier I have created view which is performing cross join (which takes time) and 2/3 Left outer join and it's taking time. To reduce execution time I have created table-valued function with parameter to reduce cross join execution time and it returns the same result as view.Just give me an idea about table-valued function and View, in terms of perfomance. Which one is better?

I am using a gridview to select a record and control that record using a details view. I am using a class based objectdatasource to link the data for select, update and delete. Sofar the select works but the update fails. Here is my error message:
ObjectDataSource 'odsDetailsView_1' could not find a non-generic method 'UpdateSet' that has parameters: setId, TYPE, iHPlayer, iAPlayer, iHRuns, iARuns, iH8Break, iA8Break, iHe8s8, iAe8s8, iH15BRn, iA15BRn, iHWins, iAWins, SET_ID, MATCH_FK, HOME_MEMBER_ID_FK, AWAY_MEMBER_ID_FK, HOME_TABLERUN, AWAY_TABLERUN, HOME_8BALLBREAK, AWAY_8BALLBREAK, HOME_E8S8, AWAY_E8S8, HOME_15BRN, AWAY_15BRN, HOME_TOTALWON, AWAY_TOTALWON, HOME_POINTS, AWAY_POINTS, LOCKED, GROUP_FK.
The first group of parameters have lower case letters and they come from my objectdatasources update method parameters. The second group of parameters are all capitalized and they are the fields in my SQL database table (and I don't know how they wound up in the error). This might be a clue.When executing the code my class method never gets the chance to execute because the error pops up before the code gets there.
Here is my objectdatasource:

Here is my detailsview:

I use an objectdatasource programmatically to use a parameterless method when SearchWord variable is empty and a Search method with one parameter when SearchWord is not empty, the event I use is objectdatasource selecting so that I can adjust parameters conveniently, I have a problem here: I can add a new parameter and set its value but I can't remove a previously added parameter from objectdatasource selectparameters and an error raises because of this, this is the selecting method:
[Code]....
Both adding and removing the search parameter takes place in this method while adding works removing the added one Not works.

How and where can I get the returnvalue from my "DeleteGuestById" method to show the right error message to my user?
I have this:
Protected Sub gvGuestlist_OnRowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles gvGuestlist.RowCommand
If e.CommandName = "DeleteGuest" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim data As DataKey = gvGuestlist.DataKeys(index)
Dim GuestId As Integer = data.Values("id")
odsGuestlist.DeleteParameters.Clear()
odsGuestlist.DeleteParameters.Add("id", GuestId)
odsGuestlist.Delete()
End If
End Sub
In my BLL:
<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Update, False)> Public Function DeleteGuestById(ByVal ID As Integer) As Integer
Dim returnval As Integer
GuestlistAdapter.DeleteGuestById(ID, returnval)
Return returnval
End Function
I think I have to be in the ObjectDatasources' "OnDeleted" method but I have no what code to place there.

In my application at some places we have used ObjectDataSource and at other normal method calls to retrieve data.My question is then what exactly are the benefits of using ObjectDataSource ?In the example below "CODE ONE" makes a call to the Business Layer and then Binds the results to the Grid abd "CODE TWO" is using ObjectDataSource to do the same.Then how is ObjectDataSource better?
SuitableApplicant sa = new SuitableApplicant();
IList<HD.Recruitment.SuitableApplicant> list = new List<HD.Recruitment.SuitableApplicant>();
list = HS.Recruitment.RecruitmentService.GetSuitableAppls();
GridView1.DataSource = list;

Hi,
I'm attempting to develop an n-tier web application that makes use of the ObjectDataSource on a page. The page shows the classic 'user details' page to allow create, read, update and delete actions for an object within the users collection. Let me explain
that again as I think it might be the root of my issue. I have a class named 'user', I also have a class named 'users' which exposes a list of 'user' objects. It's this 'users' class that is the source of my ObjectDataSource control.
What i'm hoping to have happen is that the page will display a 'user' object from the 'users' class (which it does) and that the end user can then amend the values in a formview before updating them (it kind of does this). The problem I'm running into is
that all the 'user' objects are getting updated with th ealtered values and not just the currently displayed object. I suspect that this has something to do with the web being stateless, but i'm going 'round in circles trying to figure out where i'm going
wrong.
I can post code if required, but what i'm looking for is a decent (read as: easy to follow/understand) site where I can get a better understanding of what i'm supposed to be doing.
My environment is VS2010, C#, .NET 2.0, but I don't think the environment is the issue, merly the chair-keyboard interface.
Thanks,
Mike
