DataGrid.UnloadingRow Event

Occurs when a DataGridRow object becomes available for reuse.

Namespace:  System.Windows.Controls
Assembly:  System.Windows.Controls.Data (in System.Windows.Controls.Data.dll)

Syntax

'Declaration
Public Event UnloadingRow As EventHandler(Of DataGridRowEventArgs)
public event EventHandler<DataGridRowEventArgs> UnloadingRow
<sdk:DataGrid UnloadingRow="eventhandler"/>

Remarks

To improve performance, the DataGrid control does not instantiate a DataGridRow object for each data item in the bound data source. Instead, the data grid creates DataGridRow objects only when they are needed, and reuses them as much as possible. For example, the data grid creates a DataGridRow object for each data item that is currently in view and recycles the row when it scrolls out of view.

This event enables you to make any necessary changes to a row before it can be reused. You will typically use this event to undo any changes that were made in a LoadingRow event handler.
