BindingManagerBase.EndCurrentEdit Method

Definition

When overridden in a derived class, ends the current edit.

C#
public abstract void EndCurrentEdit ();

Examples

The following code example demonstrates both the CancelCurrentEdit and the EndCurrentEdit methods. When you call the CancelCurrentEdit methods, changes made to the data are discarded. When you call the EndCurrentEdit method, the changes are kept.

C#
private void CancelEdit()
{
    // Gets the CurrencyManager which is returned when the
    // data source is a DataView.
    BindingManagerBase myMgr =
        (CurrencyManager) BindingContext[myDataView];

    // Gets the current row and changes a value. Then cancels the
    // edit and thereby discards the changes.
    DataRowView tempRowView = (DataRowView) myMgr.Current;
    Console.WriteLine("Original: {0}", tempRowView["myCol"]);
    tempRowView["myCol"] = "These changes will be discarded";
    Console.WriteLine("Edit: {0}", tempRowView["myCol"]);
    myMgr.CancelCurrentEdit();
    Console.WriteLine("After CanceCurrentlEdit: {0}",
        tempRowView["myCol"]);
}

private void EndEdit()
{
    // Gets the CurrencyManager which is returned when the
    // data source is a DataView.
    BindingManagerBase myMgr =
        (CurrencyManager) BindingContext[myDataView];

    // Gets the current row and changes a value. Then ends the
    // edit and thereby keeps the changes.
    DataRowView tempRowView = (DataRowView) myMgr.Current;
    Console.WriteLine("Original: {0}", tempRowView["myCol"]);
    tempRowView["myCol"] = "These changes will be kept";
    Console.WriteLine("Edit: {0}", tempRowView["myCol"]);
    myMgr.EndCurrentEdit();
    Console.WriteLine("After EndCurrentEdit: {0}",
        tempRowView["myCol"]);
}

Remarks

This method is supported only if the data source implements the IEditableObject interface. In that case, changes will be saved. If the object does not implement the IEditableObject interface, changes made to the data will not be saved.
