Problem with DataTable, Insert and FillSchema

[ReneMarxis]

Hello all

first let me say i start getting an idea on how powerful data binding
is. You can hold your code as short as possible and also have a pretty
big flexibility.

Also thanks to this great community here, without you i bet many of us
would not succeed that fast.

So now to my problem :)

I use data binding to let the user add/delete/modify data. The user
has one DataGridView, where he only selects the the DataRow, and on
moving in the grid i display the bound data in Textboxes/Comboboxes.

I have one DataSet, one BindingSource and one DataView. All elements
are bound to the BindingSource.
Now on filling the Data i want to use FillSchema to have all those
nice information (Col-Names, max-length, nullable...) grabbed from the
database automatically. This works but my problem comes when adding a
new DataRow to the DataTable.
I do

//======
DataRow insertRow = ds.Tables[kdList.DSTableN ame].NewRow();
insertRow["angelegt_datum "] = DateTime.Now;
insertRow["angelegt_v on"] = Globals.user.id ;
insertRow["id_status"] = Globals.dbLists .GetStatusByNam e( "Initial" );

ds.Tables[kdList.DSTableN ame].Rows.InsertAt( insertRow, 0);
bsKunden.Positi on = 0;
//======

I get an error that some of the fields must not be null (AllowDBNull
of some Cols). I understand why this error occurs but i would like to
know if there is some way to overcome this?

I do not use strong typed DataSets nor do i want to build up the
DataTable by manually. I want to let FillSchema do that for me.

Many thanks in advance
