xsd.exe Typed DataSet generation

[Matthew Baskey]

Hello,

I am loading a DataSet from an xml file and binding it to a
hierarchical datagrid. I am trying to write some keys between the
elements in my xml file into the xsd file. When I write the keys as
elements it works and I get the

public QuestionRow FindByorder(short order) {
return ((MenuTitlesRow)(this.Rows.Find(new object[] {order})));
}

however when I change these to attributes I loose my this method when
running
xsd.exe test.xsd /d

I need my xml to be structured with attributes, is there anyway I can
do this without have to transform the final output.

There is curiously very little literature available on the web about
this and what is very basic.

Here is my xsd file....

<?xml version="1.0" standalone="yes"?>

I am trying to the following in the Update_click method of the
datagrid....
Test dst = (Test)Session("Test");
short order = Convert.ToInt16(HierarGrid1.DataKeys[e.Item.ItemIndex]);
Test.QuestionRow row =
(Test.QuestionRow)dst.Question.FindByorder(order);

also it appears DataKeys are empty...
Thanks for any light shed on this area,
Matt
