- 간단한 데이터 바인딩 방법
- BindingComplete 이벤트를 구현하여 바인딩 정보를 분석하여 바인딩 데이터를 가공하는 방법
- BindingComplete 이벤트의 호출 상황을 분석하여 바인딩이 실행되는 흐름을 파악하고, 효율적인 바인딩을 구현하는 방법
BindingComplete 이벤트 구현 예제
TRANSFORMERBindingSource.BindingComplete += new BindingCompleteEventHandler(TRANSFORMERBindingSource_BindingComplete); void TRANSFORMERBindingSource_BindingComplete ( object sender, BindingCompleteEventArgs e) { if ( e.BindingCompleteState == BindingCompleteState.Success && e.BindingCompleteContext == BindingCompleteContext.DataSourceUpdate ) { string columnname = e.Binding.BindingMemberInfo.BindingMember; TransformerDataSet.TRANSFORMERRow datasource = (TRANSFORMERBindingSource.Current as DataRowView).Row as TransformerDataSet.TRANSFORMERRow; string controlname = e.Binding.Control.Name; MessageBox.Show( controlname + "->" + "[" + columnname + " / " + datasource[columnname] + "]"); } if ( e.BindingCompleteState == BindingCompleteState.Success && e.BindingCompleteContext == BindingCompleteContext.ControlUpdate && e.Binding.Control == ConnectivityNodeNameEdit2 ) { string controlname = e.Binding.Control.Name; string columnname = e.Binding.BindingMemberInfo.BindingMember; BindingSource bindingsource = e.Binding.DataSource as BindingSource; if ( bindingsource != null && !(bindingsource.Position < 0) ) { TransformerDataSet.TRANSFORMERRow datasource = (bindingsource.Current as DataRowView).Row as TransformerDataSet.TRANSFORMERRow; MessageBox.Show("[" + columnname + "/" + datasource[columnname] + "] ->" + controlname); } else { MessageBox.Show("Invalid : " + columnname + "/" + controlname); } } if ( e.BindingCompleteState == BindingCompleteState.Success && e.BindingCompleteContext == BindingCompleteContext.ControlUpdate && e.Binding.Control == fK_CONNECTIVITYNODE2SpinEdit ) { string controlname = e.Binding.Control.Name; string columnname = e.Binding.BindingMemberInfo.BindingMember; BindingSource bindingsource = e.Binding.DataSource as BindingSource; if ( bindingsource != null && !(bindingsource.Position < 0) ) { TransformerDataSet.TRANSFORMERRow datasource = (bindingsource.Current as DataRowView).Row as TransformerDataSet.TRANSFORMERRow; MessageBox.Show("[" + columnname + "/" + datasource[columnname] + "] ->" + controlname); } else { MessageBox.Show("Invalid : " + columnname + "/" + controlname); } } if ( e.BindingCompleteState == BindingCompleteState.Success && e.BindingCompleteContext == BindingCompleteContext.ControlUpdate && e.Binding.Control == ConnectivityNodeNameEdit1 ) { string controlname = e.Binding.Control.Name; string columnname = e.Binding.BindingMemberInfo.BindingMember; BindingSource bindingsource = e.Binding.DataSource as BindingSource; if ( bindingsource != null && !(bindingsource.Position < 0) ) { TransformerDataSet.TRANSFORMERRow datasource = (bindingsource.Current as DataRowView).Row as TransformerDataSet.TRANSFORMERRow; MessageBox.Show("[" + columnname + "/" + datasource[columnname] + "] ->" + controlname); } else { MessageBox.Show("Invalid : " + columnname + "/" + controlname); } } if ( e.BindingCompleteState == BindingCompleteState.Success && e.BindingCompleteContext == BindingCompleteContext.ControlUpdate && e.Binding.Control == fK_CONNECTIVITYNODE1SpinEdit ) { string controlname = e.Binding.Control.Name; string columnname = e.Binding.BindingMemberInfo.BindingMember; BindingSource bindingsource = e.Binding.DataSource as BindingSource; if ( bindingsource != null && !(bindingsource.Position < 0) ) { TransformerDataSet.TRANSFORMERRow datasource = (bindingsource.Current as DataRowView).Row as TransformerDataSet.TRANSFORMERRow; MessageBox.Show("[" + columnname + "/" + datasource[columnname] + "] ->" + controlname); } else { MessageBox.Show("Invalid : " + columnname + "/" + controlname); } } }
