Occurs after a DataGridRow is instantiated, so that you can customize it before it is used.
public:
event EventHandler<System::Windows::Controls::DataGridRowEventArgs ^> ^ LoadingRow;public event EventHandler<System.Windows.Controls.DataGridRowEventArgs> LoadingRow;member this.LoadingRow : EventHandler<System.Windows.Controls.DataGridRowEventArgs> Public Custom Event LoadingRow As EventHandler(Of DataGridRowEventArgs) Public Event LoadingRow As EventHandler(Of DataGridRowEventArgs) Event Type
Remarks
To improve performance, the EnableRowVirtualization property is set to true by default. When the EnableRowVirtualization property is set to true, the DataGrid does not instantiate a DataGridRow object for each data item in the bound data source. Instead, the DataGrid creates DataGridRow objects only when they are needed, and reuses them as much as it can. For example, the DataGrid 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 is used. To undo these customizations before a row is reused, handle the UnloadingRow event.
