objectdatasource.update() fires System.InvalidOperationException

hello,
we have a strange error message here:

I've written a small detail sample page, where I can update one reocrd with
an objectdatasource control and the detailsview control.
the objectdatasource.confictdetection is set to 'CompareAllValues'. The
Updatemethod is UpdateXY and I've set two updateparameters classX and
original_callsX.

when I use the update link provided by the detailsview control, everything
works as expected.

The problem comes now:
I added a button on the page and labeled it 'Update'. In the clicked event I
added the code objectdatasource1.Update().
Here the following exception is fired immediatelly:
You have specified that your update method compares all values on
ObjectDataSource 'odsCommodity', but the dictionary passed in for oldValues
is empty. Pass in a valid dictionary for update or change your mode to
OverwriteChanges.

Hi Markus,

Welcome to ASPNET newsgroup.
Regarding on the ObjectDatasource.Update method throw exception problem,
based on my understanding, it is because when you manually call the
ObjectDataSource.Update method, it hasn't be supplied the required
inputParameters. When we use the DetailsView or GridView's "update" button,
those parameters will be retrieved from the detailsview or GridView's
current edit item....

So for your scenario, we'd suggest you consider the following means to do
update(for the current edit row) in our own submit button"

1. Instead of calling ObjectDataSource.Update method, we call
DetailsView.UpdateItem method, this method will update the current Item(in
edit mode).. And it'll help retreive the required parameters from the
DetailsView, just as when we click the "update" button generated by
DetailsView.....   e.g:

protected void btnUpdate_Click(object sender, EventArgs e)
    {
        if (DetailsView1.CurrentMode == DetailsViewMode.Edit)
        {
            DetailsView1.UpdateItem(true);
         }

    }

2. Also, we can use the ObjectDataSource.Update method, however, we need
also intercept the event through the ObjectDatasource's "Updating" event,
at there we can manually supply all the parameters required or updating.
e.g:

protected void btnUpdate_Click(object sender, EventArgs e)
    {
        if (DetailsView1.CurrentMode == DetailsViewMode.Edit)
        {
                 ObjectDataSource1.Update();
        }

    }

protected void ObjectDataSource1_Updating(object sender,
ObjectDataSourceMethodEventArgs e)
    {
        Response.Write("<br>Count: " + e.InputParameters.Count);
        foreach (System.Collections.DictionaryEntry param in
e.InputParameters)
        {
            Response.Write("<br>" + param.Key + " " + param.Value);
        }

    }

#I just print out all the required parameters ... You need to assign the
correct value in each entry (since they're all empty when we manually call
ObjectDataSource.Update....)

Hope helps. Thanks,

Steven Cheng
