Can't get a my DataGrid to work .. I'm busted or its busted

bob
I cannot seem to display any info with my Data Grid ... the online examples
I have seen 'appear' to say the same thing.
create a DataTable then simply call something like this myDataGrid.Source =
myDataTable. I'm missing something fundemental here cos I get big black
nothing.

here's some code snippets.

public class Form1 : System.Windows.Forms.Form
{
// declarations section

private System.Windows.Forms.DataGrid dataGrid1;
private DataTable myDataTable2;
private DataColumn myColumn2;
private DataRow myRowItem2;

private void Form1_Load(object sender, EventArgs e)
{// create an in memory database
myDataTable2 = new DataTable("Machine_Events2");
myColumn2 = new DataColumn("ID", System.Type.GetType("System.Int32"));
myDataTable2.Columns.Add( myColumn2 );
myColumn2 = new DataColumn("theTime", System.Type.GetType("System.String"));
myDataTable2.Columns.Add( myColumn2 );
myColumn2 = new DataColumn("machine_state",
System.Type.GetType("System.String"));
myDataTable2.Columns.Add( myColumn2 );

myRowItem2 = myDataTable2.NewRow();
myRowItem2["ID"] = 1;
myRowItem2["theTime"] = "Some time";
myRowItem2["machine_state"] = "Some_State";
myDataTable2.Rows.Add(myRowItem2);

myRowItem2 = myDataTable2.NewRow();
myRowItem2["ID"] = 2;
myRowItem2["theTime"] = "more time";
myRowItem2["machine_state"] = "Another_State";
myDataTable2.Rows.Add(myRowItem2);

myRowItem2 = myDataTable2.NewRow();
myRowItem2["ID"] = 3;
myRowItem2["theTime"] = "yet_more time";
myRowItem2["machine_state"] = "yet_Another_State";
myDataTable2.Rows.Add(myRowItem2);

dataGrid1 = new DataGrid();
dataGrid1.DataSource = myDataTable2;

Sorry bout the poor formatting ... when I debug and scroll through the
watch window it certainly appears that myDataTable2 exists and is populated
... datagrid1 doesn't seem to believe so. I dropped the datagrid in with
using VS2003 IDE .. so all the windows form designer code is untouched ...
and it certainly displays the blank DataGrid when I execute ... just not
populated.

regards and tnx for any guidance Bob.

OK ... so there are some trees there in that forest ... I'll take my foot
out of my mouth now.

I figured it out ... went bit mad declaring things ... redeclared the
datagrid1 control ...
