DataSet.OnRemoveTable Method

Occurs when a DataTable is removed from a DataSet.

Namespace: System.Data
Assembly: System.Data (in system.data.dll)

protected internal virtual void OnRemoveTable (
	DataTable table
)
protected void OnRemoveTable (
	DataTable table
)
protected internal function OnRemoveTable (
	table : DataTable
)

Parameters

table

The DataTable being removed.

This method can be overridden by subclasses to restrict tables from being removed.

The following example shows a class derived from the DataSet with the OnRemoveTable method overridden.


public static void DemonstrateOnRemoveTable()
{
    DerivedDataSet dataSet = CreateDataSet();
    if(dataSet.Tables.Count > 0)
        dataSet.Tables.RemoveAt(0);


public class DerivedDataSet: DataSet
{
    protected override void OnRemoveTable(DataTable table)
    {
        Console.WriteLine(
            "The '{0' DataTable has been removed from the DataSet", 
            table.TableName);
    


public static DerivedDataSet CreateDataSet()
{
    // Create a DataSet with one table containing two columns.
    DerivedDataSet derived = new DerivedDataSet();

    // Add table to DataSet.
    DataTable table = derived.Tables.Add("Items");

    // Add two columns.
    DataColumn column = table.Columns.Add("id", typeof(int));
    column.AutoIncrement = true;
    table.Columns.Add("item", typeof(int));

    // Set primary key.
    table.PrimaryKey = new DataColumn[] {table.Columns["id"];

    return derived;
