Error Message: Specified cast is not valid.

System.InvalidC astException: Specified cast is not valid.

I am using C# and backend is Oracle9i. I am using
ODP.NET for data access provider.

As ODP says.. it converts Oracle NUMBER type to
System.Decimal and I dont know if this has something to
do with the error.

The error occurs on: MyDataGrid.Data Bind(); line

DataSet ds = new DataSet();
oWS = new Workspace();
oWS.getHighligh t(ref ds, WEDList.Selecte dItem.Value,
ProjectList.Sel ectedItem.Value , "Highlights ");
MyDataGrid.Data Source=ds.Table s["Highlights "].DefaultView;
MyDataGrid.Data Bind();

The data itself is fine and the package procedure is
working fine.

procedure getHighlight
(p_WED_PK in Int, p_Project_PK in Int, ReturnCursor
out retcur)
as
BEGIN
OPEN ReturnCursor FOR
Select Highlight_PK, Summary, DateRecorded,
Assigned_FK, User_FK, WED_FK, Category, Category_FK
From Highlights, Category
Where WED_FK = p_WED_PK and
Assigned_FK=p_P roject_PK
and Category_FK(+)= Category_PK;
END getHighlight;

I cant figure out what the problem is.

Any ideas?
