I am working on a windows.net application and having problem binding to a datagrid.  I believe it has something to do a child relationship, if so, how can I remove the relationship before binding?  

An unhandled exception of type 'System.ArgumentException' occurred in system.windows.forms.dll

Additional information: Cannot create a child list for field tblEquipmentInventory.

//Initalize dataset.
  this.ds.Clear();
  this.ds.AcceptChanges();
//Get data from tables tblEquipmentInventory, facility, customer...)                               
  this.ds = this.bizObj.FilterByScenario(this.dsCustomer, this.lbscenario.Text.ToString(), nchCustomerID.ToString());
  string expression = "EquipmentColA = 1";
  DataView dv = ds.Tables["tblEquipmentInventory"].DefaultView;
//Only get rows ColA = 1
  dv.RowFilter = expression;
  this.dgEquipment.DataSource = dv;
//Bind to datagrid
   this.dgEquipment.SetDataBinding(dv, "tblEquipmentInventory")

Hi there,

Try to remove this line:

//Bind to datagrid
   this.dgEquipment.SetDataBinding(dv, "tblEquipmentInventory");

Yes, you can, but the SetDataBinding arguments are (DataSource, DataMember). and tblEquipmentInventory is not a valid member of it's own default view.

You could have used:
//Bind to datagrid
   this.dgEquipment.SetDataBinding(dv, "");

I think.
