Hello Dear;
    I am starting my development with DevForce. I am getting well along with it but I have come accross ascenario I would like guidance from any person having experience with DevForce.
 
I have a form with controls bould to a BindingSource which i then bound BindableList of entities. I can Adding and Editing without problems. However when I try to Delete Items with my Binding Navigator they still appear on the form.
 
I use something like this

(contractBindingSource.Current as Contract).Delete(); for a Contract which contains Facilities ( Entities in my System) and to delete a facility I call something like this (Using XtraGrid)

private void OnKeyDown(object sender, KeyEventArgs e)

{

if (e.KeyCode == Keys.Delete)

{

(facilitiesBindingSource.Current as ContractFacility).Delete();

}

}

Please can anybody help me with this.

Please consider this.. pseudocode of sorts...


if (e.KeyCode == Keys.Delete)

Entity myentity = gridView1.GetFocusedRow() as Entity;
if myentity != null && !EntityAspect.isnullentity

DialogResult result = xtramessagebox.show(etc etc etc)

if result == dialogresult.yes
myentity.EntityAspect.Delete();
bindingsource.RemoveCurrent();


where bindingsource is a private System.Windows.Forms.BindingSource

Thank you very much;
  I tried that before and it actually it worked but I was not sure if that is the way it is supposed to be done.
And I have tested. It is OK.
Thanks again.
