HeaderCheckBoxEventFiring Property

Returns or sets a value which determines whether the ValueChanged event fires for each cell whose value changes as a result of changes in the header checkbox value, or only once after all cell values have been changed.

Public Property HeaderCheckBoxEventFiring As HeaderCheckBoxEventFiring
public HeaderCheckBoxEventFiring HeaderCheckBoxEventFiring {get; set;}
Remarks

When a column header's CheckBoxVisibility property is set to a value which causes a checkbox to appear on the header, and that checkbox is clicked, the value of each cell in that column may be changed, subsequently causing the control's ValueChanged event to fire. This can affect performance in cases where the control has a relatively large number of rows. Setting this property to 'OnHeaderCheckboxValueChange' improves performance by deferring the firing of the ValueChanged event until after each cell's value has been changed.
