RowRemoved Event

Overview

Occurs when an observable table removes a row. Subscribe here if you must keep external caches (for example, a lookup dictionary) in sync with table contents.

Declaration

/// <summary>
/// RowsRemoved event
/// IObservableDataTable interface implementation
/// </summary>
public event EventHandler<RowsChangedEventArgs>? RowRemoved;

Namespace and Assembly

Namespace: PocoDataSet.ObservableData
Assembly: PocoDataSet.ObservableData.dll

Usage Example

// 1. Create observable data set
IObservableDataSet observableDataSet = new ObservableDataSet();

// 2. Subsribe to ObservableDataSet.RowRemoved event
observableDataSet.RowRemoved += ObservableDataSet_RowRemoved;

// 3. Add observable table to observable data set
IObservableDataTable department = observableDataSet.AddNewTable("Department");
department.AddColumn("Id", DataTypeNames.INT32, isPrimaryKey: true);
department.AddColumn("Name", DataTypeNames.STRING);

// 4. Add a new observable data row to observable data table
IObservableDataRow row = department.AddNewRow();

// 5. Remove row from observable data table and observe that RowRemoved event was raised and handled
department.RemoveRow(row);

static void ObservableDataSet_RowRemoved(object? sender, RowsChangedEventArgs e)
{
    Console.WriteLine($"Row removed from {e.TableName} at index {e.RowIndex}.");
}
