Good afternoon,
I have a very strange problem. When I execute the code below the
program throws an InvalidCastExce ption. When I debug the code I see
e.Item.DataItem is an object from the type OrganisatieOnde rdeel. When
you read the additional you can see the types are the same. How can I
solve this problem?
Kinds regards,
Lammert
Code:
protected void fvwContact_Item DataBound(objec t sender,
DataListItemEve ntArgs e)
{
ObjectDataSourc e ods = new ObjectDataSourc e();
ods.TypeName = "BusinessLogicL ayer.FunctieVer vulling";
ods.SelectMetho d = "GetFunctieVerv ullingenById";
// An exception of type 'System.Invalid CastException' occurred in this
this line:
OrganisatieOnde rdeel oo =
(OrganisatieOnd erdeel)e.Item.D ataItem;
ods.SelectParam eters.Add("id", TypeCode.Int32,
oo.Id.ToString( ));
DataList ds = (DataList)e.Ite m.FindControl(" dlPersonen");
ds.DataSource = ods;
ds.DataBind();
}
Message:
An exception of type 'System.Invalid CastException' occurred in
WebApp.DLL but was not handled in user code
Additional information: Unable to cast object of type
'BusinessLogicL ayer.Organisati eOnderdeel' to type
'BusinessLogicL ayer.Organisati eOnderdeel'.

Lammert,
You have to filter out all non-data items with something like this:
ListItemType itemType = e.Item.ItemType ;
if ((itemType == ListItemType.Pa ger) ||
(itemType == ListItemType.He ader) ||
(itemType == ListItemType.Fo oter))
{
return;
}

This doesn't work. When I cast an Object (OrganisatieOnd erdeel) to
OrganisatieOnde rdeel the program throws an InvalidCastExce ption. For
example e.Item.DataItem contains an Object of the type
OrganisatieOnde rdeel, but I can't cast this to OrganisatieOnde rdeel!!
Are there any solutions??

Did you check in the debugger that e.Item.DataItem indeed is an object of
the type
OrganisatieOnde rdeel?
