In This Topic
    DefaultCalculateDistinctValues Property (DataGridCollectionViewSourceBase)
    In This Topic
    Get or sets the default value of the CalculateDistinctValues property when a DataGridItemProperty has not explicitly set its value.
    Syntax
    '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

    true if distinct values are to be calculated; false otherwise. By default (if automatic filtering is enabled), true.
    Remarks
    If a column does not need to support automatic filtering, it is recommended to set its corresponding DataGridItemProperty's CalculateDistinctValues tofalse or set the DataGridCollectionViewSource or DataGridDetailDescription's DefaultCalculateDistinctValues properties to false and only set CalculateDistinctValues to true for the item properties that will support auto-filtering
