ObjectDataSourc e UpdateMethod question

I have a FormView that shows details of a specific record on a table. The
SelecMethod returns a DataSet that includes all the fields from my Event
table and other read-only fields from linked tables. My FormView has
controls that are bound to the fiuelds on the dataset table. I am now
changing the FormView's Default Mode to Edit but I am having problems with
the related fields.

My ObjectDataSourc e is defined as:

<asp:ObjectData Source ID="ObjectDataS ourceEventDetai ls"
runat="server" OldValuesParame terFormatString ="original_{ 0}"
SelectMethod="S electEventDetai ls" TypeName="Event Data"
DataObjectTypeN ame="System.Dat a.DataSet" UpdateMethod="U pdateEventDetai ls">
<SelectParamete rs>
<asp:ControlPar ameter ControlID="Grid ViewEvents"
Name="eventID" PropertyName="S electedValue"
Type="Int64" />
</SelectParameter s>
</asp:ObjectDataS ource>
The EventData.Selec EventDetails performs a join with related tables and
returns a single table in a dataset with both the Event fields and the
related fields.

The EventData.Updat eEventDetails funcion takes as parameters the
original_EventI D and only the editable fields that belong to the Event

public void UpdateEventDeta ils(long original_EventI D, byte SendState,
string EntryNotes)
I added a button to save changes and when the button is pressed I called:
FormView1.Updat eItem(true);
When UpdateItem is called I receive the following exception:

Could not find a property named 'ImageIndex' on the type specified by the
DataObjectTypeN ame property in ObjectDataSourc e
'ObjectDataSour ceEventDetails' .

ImageIndex is a field found on a related table which is not updated by
UpdateEventDeta ils.

I am not sure if I should limit the SelectMethod to return the table and
do the databinding for the read only fields a different way.

Hi Jeronimo,

Thank you for your post!

ObjectDataSourc e.DataObjectTyp eName is used to get or set the name of a
class that the ObjectDataSourc e control uses for a parameter in an update,
insert, or delete data operation, instead of passing individual values from
the data-bound control.

Since your UpdateMethod of ObjectDataSourc e is passing individual values,
you should remove 'DataObjectType Name="System.Da ta.DataSet"' part from your
ObjectDataSourc e declaration.

For more information, see MSDN documentation on this property:
asource.dataobj ecttypename(d=i de).aspx

Hope this helps. If anything is unclear, please feel free to post here.

I'm having some trouble using the ObjectDataSource in ASP.NET 2.0. I have a wrapper that contains the static methods for Select and Update. The Update-method takes the business object as parameter. When the Update-method is invoked by the ObjectDataSource, the object referenced is not the same object returned by the Select-method, but a new object with only the values from the Edit-template. So basically I get a reference to a useless...

I don't want to use the "built-in" way to do it because I am using business layer methods for updating and deleteing and I don't want to have my parameter names in those methods have to be "original_Parametername" or even if I change the OldValuesParameterFormatString to get rid of the "original" I would still have just "Parametername".
