C# - ObjectDataSource Could Not Find A Non-generic Method?
Dec 20, 2010I 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?

View 5 RepliesObjectDataSource Cannot Find Type When Deployed To SharePoint
May 1, 2010I'm receiving the following error when deploying a feature containing ASP.NET pages to our development SharePoint servers: System.InvalidOperationException: The type specified in the TypeName property of ObjectDataSource 'odsYears' could not be found. Our .dll is being deployed to the GAC and our pages are being deployed to the the respective Features directory in the 12 hive. We are not receiving this error on our Sandbox SharePoint server. I disassembled the .dll to be sure the class was being deployed and everything looked ok. why this would not work on one of our SharePoint environments?

Accessing BLL With ObjectDataSource - Could Not Find A Non-generic Method?
Nov 25, 2010I'm a starting C# programmer and I'm experiencing the following problem.I've created a dataset in Visual Studio With a table for persons making use of two table adapters, one for selecting all persons and one for selecting one person at a time filtered by the personID (Guid). This is a seperate project of my solution. After that I created a new project for the Business Logic Layer
private PersonenTableAdapter personenAdapter = null;
protected PersonenTableAdapter Adapter
{get....}
[System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, true)]
public DAL.Testdatabase.PersonenDataTable GetPersonen()
{...}
[System.ComponentModel.DataObjectMethodAttribute (System.ComponentModel.DataObjectMethodType.Select, false)]
public DAL.Testdatabase.PersonenDataTable GetPersonenByID(Guid ID)
{...}
[System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Update, true)]
public bool updatePersoon(string Voornaam, string Achternaam, string Geslacht, string Adres, string Huisnr, string Postcode, string Plaats, string Telnr, string GSM, string BSN, DateTime? CreateDate, string CreatedBy, DateTime? LastModifiedDate, string LastModifiedBy, bool? Actief, DateTime? DatumInactief, Guid ID)
{...}
When issueing the Update method using a detailsview with an Objectdatasource i get the following error.
ObjectDataSource 'ObjectDataSource1' could not find a non-generic method 'updatePersoon' that has parameters: Voornaam, Achternaam, Geslacht, Adres, HuisNr, Postcode, Plaats, Telnr, GSM, BSN, CreateDate, CreatedBy, LastModifiedDate, LastModifiedBy, Actief, DatumInactief, original_ID.

DataSource Controls :: ObjectDataSource - Update Method To Pass Entity To The Method In BLL Class?
Oct 18, 2010I 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?

How To Find The File Path From A Namespace.class Name
Aug 26, 2010I'm programatically looking ito a .aspx file and getting the file class name declared in its CodeBehind. For example, when analyzing myFile.aspx I read in its Page Directive and found its CodeBehind equals "myApplicationmyPage.aspx.vb". Then I use the code
below:
[Code]....
Now I want to read the BaseFile (class = myApplication.Forms.BasePage). However, to read in this file, I need I need to get its full path instead of its namespace.class hiearchy. In this case, the BasePage is wrapped in a different namespace declaration thus I cannot just change the '.' to '' in order to get the path.How can I get the path of BasePage so I can read it?
Connected Database - To Find Its TableAdapter Class?
Aug 19, 2010I can't see it nowhere in Visual Studio's Solution Explorer. The tutorial that I am following is using the Northwind database and hence the need to add the code line "using NorthWindTableAdatpter;" statement.So I thought I needed to add "using myDBTableAdapters" statement in my code which I did, but it's giving an error saying:
"The type or namespace name 'myDbTableAdapters' could not be found (are you missing a using directive or an assembly reference?)"
What's wrong? Where is the class for myDB's table adapter? I searched the .xsd file, but there's no mention of "myDBTableAdapters".It's not there in the Solution Explorer.
