ToList () . Exists ( anyAcc => { return anyAcc . Name == Acc1 ; }) == false ) { Form acc = new Form (); acc . Name = Acc1 ; // this is the key! acc . Text = acc . Name ; acc . MdiParent = this ; acc . Show (); return ; } if ( MdiChildren . ToList () . Exists ( anyAcc => { return anyAcc . Name == Acc2 ; }) == false ) { Form acc = new Form (); acc . Name = Acc2 ; // this is the key! acc . Text = acc . Name ; acc . MdiParent = this ; acc . Show (); return ; } if ( MdiChildren . ToList () . Exists ( anyAcc => { return anyAcc . Name == Acc3 ; }) == false ) { Form acc = new Form (); acc . Name = Acc3 ; // this is the key! acc . Text = acc . Name ; acc . MdiParent = this ; acc . Show (); return ; } I have used MDI interface. By my opinion for using on the pannel the UserControls is better. ;-)
