DataGridColumnStyle.BeginUpdate Method ()
Suspends the painting of the column until the EndUpdate method is called.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When many changes are made to the appearance of a System.Windows.Forms.DataGrid control (whether the changes are in the attributes of the column or the data displayed by the control), you should invoke the method to temporarily freeze the drawing of the control. This results in less distraction to the user, and a performance gain. After all updates have been made, invoke the EndUpdate method to resume drawing of the control.
