This is the first time I have been working on databases and I am trying to insert data using an object datasource but no data is being inserted and no exception is thrown. I'm not sure where I am going to wrong. I am putting user data into session variables and inserting the session variables into the dataacess class layer and have a try and exception but nothing being thrown. Any help would be really appreciated because I don't know even where to start looking with this or how I can get the error to be thrown. Please see some of my code below to give an idea of what I am doing

I am using a list of objects as a datasource and passing the object into a user control. I use the code outlined below
[code]...
When I try to access the object this way, it's null.
Funny thing, I can access the user control and all the control data in the user control, but the object (both in the gridview and passed to the user control) are null.

How do I accept an 'object' as a Datasource (IEnumerable or IList) and loop through the keys/values? I want to be able to pass anything that implements either IEnumerable or IList.
This same functionality exists on all of the .Net DataBound controls and I'm trying to figure out how it's done.

I have a need to add a new report to my page, the differnent parts of the page are all using a objectdatasource to populate the data. The new report because of all the data being returned i have started to use a repeater and a table in the ItemTemplate. Just binding the objectdatasource to the repeater works fine, but returns all the records and causes the page to be very long. I found this link for adding paging to repeater, but its setup different than what i have
[URL]
Is there any way to use what i have already and add paging to the repeater?

Traditionally with an Object Data Source, the wired up class will have its public properties available for binding (i.e. Gridview columns, etc.) which works well. But what if one of my wired up business objects has a property that is an object itself; can I drill down to a property on that object property and still use it?
So in additiona to the traditional:MyBusniessObject.OrderID...I want to use:MyBusniessObject.Customer.NameID
Your 1st response might be to just wire up the 'Customer' class, but I need properties both on 'MyBusinessObject'and 'Customer'. I do not think this can be done, as the ODS will not display properties on an object instance property. I have tried manually typing in the drilled down value as well, but that wasn't a success either.

I have a data object named Usertype. The Database table is also called Usertype. I need to have an enum representing Usertypes also. What would proper naming convention be for the Usertype Enum? It can't be Usertype. But I can't append an E or "Enum" to it anywhere. What would be the proper name for the Enum?

I have an object data source that is being used by an rdlc report, and the object data source uses a filter that is built from session variables passed to the page.
The report displays correctly, with the filter applied; however, I want to mark each of the rows as "printed" in a bit field in the database table.
In the table adapter, I have the following Update command that is used by the object data source:
UPDATE dbo.WorkOrder
SET boolWorkOrderPrinted = 'True'
WHERE (WorkOrderID = @Original_WorkOrderID)
And in the Page Load event, I run:
ObjectDataSource1.Update();
However, no records are updated.

When my page is first loaded i receive error message stating to the effect
cant find Email for GetInvoicesByVendor.
this refers to a function in another class file:
Public Shared Function GetInvoicesByVendor(ByVal Email As String, ByVal vendorid As Integer) _
As IEnumerable
yet i only want to execute this function during the button click event and not when page is first loaded with the following parameters:
vendorid.Text = 1
txtcustomerid.Text = test@yahoo.co.uk
My objectdatasource is declared as follows:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"

How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.
[code]....
I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
