'Declaration
 
Public Property DefaultCalculateDistinctValues As Boolean

'Usage
 
Dim instance As DataGridCollectionViewSourceBase
Dim value As Boolean
 
instance.DefaultCalculateDistinctValues = value
 
value = instance.DefaultCalculateDistinctValues

public bool DefaultCalculateDistinctValues {get; set;}

Property Value

The value is true if distinct values are to be calculated; it is false otherwise. By default (if automatic filtering is enabled), it will be true.

If a Column does not need to support automatic filtering, it is recommended to set its corresponding DataGridItemPropertyBase's CalculateDistinctValues to false or set the DataGridCollectionViewSourceBase's DefaultCalculateDistinctValues properties to false & only set CalculateDistinctValues to true for the item properties that will support auto-filtering.
