Accessing An Object That Implements SelectMethod For ObjectDataSource?
Nov 8, 2010Is it possible to access an object that is used by ObjectDataSource to retrieve records? For example,
<asp:ObjectDataSource ID="MyDS" runat="server"
SelectMethod="getUsers"
TypeName="DataSources.UserDS"
SelectCountMethod = "getUserNum"/>... </asp:ObjectDataSource>
UserDS class has getUsers that returns DataTable and getUserNum that returns int, this part works as it's supposed. But I wonder if can access the instance of UserDS somehow (not underlying DataTable)?

C# - How To Use Global Variables In ObjectDataSource.SelectMethod
Sep 10, 2010I'm using ListView + DataPager + ObjectDataSource mix.
In the implementation of my SelectMethod of an ObjectDataSource I'd like to access a global variable set in the PageLoad() event (the method will return just the proper number of items per page). Although the variable is initialized in PageLoad() it appears to be null in SelectMethod. How can I change that?

View 2 RepliesDataSource Controls :: Passing Object To ObjectDataSource.SelectParameters Collection
Mar 30, 2010I'm trying to use an ObjectDataSource's SelectMethod() to retrieve a result set from a sql server database to populate a data table with various stored procs that have any given number of parameters. My approach is to pass an object which contains the stored proc name and information about its parameters into the SelectMethod(). My issue is that I don't know how to actually set the default value. Here is the code I have so far:
ObjectDataSource1.DataObjectTypeName = "WebApplication1.Children";
ObjectDataSource1.TypeName = "WebApplication1.Children";
ObjectDataSource1.SelectMethod = "Select";
Parameter odsParameter = new Parameter() { Name = "storedProc", Type = TypeCode.Object };
// How do you set the default value to reference an object?
ObjectDataSource1.SelectParameters.Add(odsParameter);
namespace WebApplication1
{
public class Children
{
public DataTable Select(object storedProc)
{
// do stuff here and get db values.
}
}
}
The default value of a Parameter object is a string type. Does anyone know how to set the default value with an object or how I can pass an object into the SelectMethod?

SelectMethod In ObjectDatasource Getting Called Multiple Times With Multiple Datapagerfield?
Oct 7, 2010so here is the setup. I am building a page that has a listview, a datapager, and 3 datapagerfield (2 x NextPreviousPagerField, 1 x NumericPagerField), and a objectdatasource to tide all of this together.
It was all working fine until I put a breakpoint into the SelectMethod specified in the objectdatsource control. It seems like that for each datapagerfield control, it is calling the selectmethod and selectcount method. Hence, whenever a user paged, it calls the database 6 times instead of 2 (I don't have caching turned on atm). If I remove one datapagerfield, it will remove 2 calls.
Now this is build in asp.net 3.5 SP1 in VS2008. When I copied the same code files to a asp.net 4.0 VS2010 solution, it duplicate call seems to be gone.
Is this a bug in asp.net 3.5 SP1?
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?

i would like to control my objectdatasource from the code behind based on the button you click.
here is what i have right now.. but if possible, can this source not be hardcoded like this and only built in the code behind?

How To Use A Viewstate'd Object As A Datasource For Controls On User Control
Dec 29, 2010I've got a listview on a control. Each row comprises a checkbox and another listview.
The outer listview is bound to a property on the control (via a method call, can't set a property as a SelectMethod on an ObjectDataSource it would appear) which is lazy loaded suchly:
[Code]....
The reason for the use of viewstate is this:
When an one of the checkboxes on one of the outer list view rows is checked or unchecked I want to modify the object that the ODS represents (for example I'll add a couple of Charge objects to the relevant Product object) and then rebind.
The problem I'm getting is that after every postback (specifically after checking or unchecking one of the rows' checkbox) my viewstate is empty. Thiss means that any changes I make to my viewstate'd object is lost.
Now, I've worked out (after much googling and reading, amongst many others, Scott Mitchel's excellent bit on ViewState) that during initial databinding IsTrackingViewState is set to false. That means, I think, that assigning the return from GetWebServiceProductLineChargeDetails() to the ViewState item in my Property Get during the initial databind won't work.
Mind you, even when the IsTrackingViewState is true and I call the Property Get, come the next postback, the viewstate is empty.
how I keep the object referenced by the ObjectDataSource in ViewState between postbacks and update it and get those changes to stay in ViewState?
