Can't access DataItem in FormView when updating

[Bresco]

I'm using ObjectDatasourc e in combination with a Formview. The
ObjectDatasourc e is connected to a FormView.

I have a business object property which I can't update through the normal
binding since it's a custom enum type. I managed to access the buinsess
object through the FormView.DataIt em property in the OnDataBinding event so
that I can fill a dropdownlist with the correct value by casting the enum
type to an int.

However,when trying to get the data OUT of the control into the business
object I can't seem to get access to the DataItem (i.e. the business object)
since it's null in the OnItemInserting and OnItemUpdating events. I tried
all kinds of things to get hold of the business object but nothing seems to
work.

Anyone know how to get the DataItem when saving?

Well, I 'solved' it, although I still find it very unintuitive that ASP.NET
does not make the DataItem available in the OnInserting, OnUpdating events.

Here's what I did:

protected void FormView1_ItemU pdating(object sender, FormViewUpdateE ventArgs
e)
{
DropDownList ddl = this.FormView1. FindControl("Dr opDownlist1") as
DropDownList;
e.NewValues.Add ("EnumTypePrope rty", ddl.SelectedInd ex.ToString());
}

For some reason, ASP.NET seems to automatically cast the string in the
EnumTypePropert y to EnumType before putting it in the property.

Note that to get the property into the DropDownList you have to handle the
DropDownList1_D ataBinding like:

protected void DropDownList1_D ataBinding(obje ct sender, EventArgs e)
{
MyBizObject bo = FormView1.DataI tem as BizObject;
DropDownList ddl = this.FormView1. FindControl("Dr opDownlist1") as
DropDownList;
ddl.SelectedInd ex = (int)bo.EnumTyp ePropererty;
}

you can't handle the FormView1_DataB inding since the DataItem will then be
NULL.
