Forms Data Controls :: DetailsView Delete Method Passing Null Values To Objectdatasource Underlying Object Delete Method

Apr 12, 2010

I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below

Forms Data Controls :: DetailsView's ObjectDataSource Update Method Fails?

Jan 15, 2011

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:

DataSource Controls :: ObjectDataSource - Update Method To Pass Entity To The Method In BLL Class?

Oct 18, 2010

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?

DataSource Controls :: Getting Returnvalue From Objectdatasource Delete Method?

Jul 13, 2010

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.

DataSource Controls :: Benefits Of Using ObjectDataSource Over Normal Method Calls?

Jul 6, 2010

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();

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.

C# - ObjectDataSource Could Not Find A Non-generic Method?

Dec 20, 2010

I have this ASP.NET code:

<asp:DropDownList
ID="ddlBrokers"
runat="server"
AutoPostBack="true"
DataSourceID="srcBrokers"
DataTextField="broker"
DataValueField="brokerId"
/>
<asp:ObjectDataSource
id="srcBrokers"
TypeName="DatabaseComponent.DBUtil"
SelectMethod="GetBrokers"
runat="server">
</asp:ObjectDataSource>

My DAL code:

public DataTable GetBrokers(bool? hasImport=null)
{
SqlCommand cmd = new SqlCommand("usp_GetBrokers");
if (hasImport.HasValue)
cmd.Parameters.AddWithValue("@hasImport", hasImport);
return FillDataTable(cmd, "brokers");
}

When the form loads I get this error:

ObjectDataSource 'srcBrokers' could not find a non-generic method 'GetBrokers' that has no parameters.

Is it my optional parameter that is causing the problem? How can I workaround this? Is it possible to have optional parameters with declarative ASP.NET code?
