Thanks for your reply.
But i am getting an exception
cannot create a child list for field Table2
I used the following
string strSql=@"Select * from Table2";
da=new OleDbDataAdapter(strSql,constr);
ds.Clear();
da.Fill(ds,"Table2");
DataView dv=new DataView(ds.Tables["Table2"]);
dv.AllowNew=false;
this.dataGrid1.DataSource=dv;
this.dataGrid1.SetDataBinding(dv,"Table2");
Thanks
