Public Property Handled As Boolean

Property Value

Type	Description
Boolean	A value that specifies whether the event is handled and no default processing is required.

Remarks

Set this parameter to true to indicate that no default processing is required. In this instance, the Visible property specifies the row visibility. The row will be visible or hidden regardless of the tree list’s filter.

If this parameter is set to false the Visible property is ignored. The row will be visible if it matches the tree list’s criteria (see IsFitDefaultFilter), otherwise, the row will be hidden.
