System.Windows.Forms.DataSourceUpdateMode Enumeration

Specifies when a data source is updated when changes occur in the bound control.

Syntax

public enum DataSourceUpdateMode

Remarks

When a control is bound to a data source using a System.Windows.Forms.Binding object, you can specify when an update to the data source will occur using the System.Windows.Forms.DataSourceUpdateMode enumeration.

When the update mode is DataSourceUpdateMode.Never, you can force the data source to be updated by using the Binding.WriteValue method.

Note:

Even when the update mode is set to DataSourceUpdateMode.Never, the data source will be updated when the binding is first created, so at that least one update will always occur.
