C# Infragistics - Delete Row - Add to Initialize Component

So, I want to add the below code to my winform.  However in order for it to fire I need to add it to the Initialize component.  Anyone know how to add it?

public void ultraGrid1_BeforeRowsDeleted(object sender, Infragistics.Win.UltraWinGrid.BeforeRowsDeletedEventArgs e)
{
}

Select all Open in new window

I've tried below but getting an error on ultraGrid1_BeforeRowsDeleted().  Says its missing BeforeRowsDeletedEventArgs.

this.ultraGrid1.InitializeRow += new Infragistics.Win.UltraWinGrid.InitializeRowEventHandler(this.ultraGrid1_BeforeRowsDeleted(this, ????));

Select all Open in new window
