Methods

CloneCore(Cloneable)

Creates a deep copy of this group description by copying core properties including sort order and group comparer. This method ensures that cloned instances maintain their grouping and sorting configuration independently.

Declaration

cs-api-definition
protected override void CloneCore(Cloneable source)

Parameters

source

Cloneable

The source group description to clone from.

Overrides QueryableGroupDescription.CloneCore(Cloneable)

Remarks

Notes to Inheritors If you derive from Cloneable, you may need to override this method to copy all properties. It is essential that all implementations call the base implementation of this method (if you don't call base you should manually copy all needed properties including base properties).

CreateGroupKeyExpression(IEnumerable<Expression>)

Creates the group key expression.

Declaration

cs-api-definition
protected override Expression CreateGroupKeyExpression(IEnumerable<Expression> valueExpressions)

Parameters

valueExpressions

IEnumerable<Expression>

Value expressions used for generating group key.

Returns

Expression

Expression that creates group key for the given item.

Overrides QueryableGroupDescription.CreateGroupKeyExpression(IEnumerable<Expression>)

CreateGroupKeyValuesExpressions(ParameterExpression)

Creates value expressions for values that will be used for generating group key expression.

Declaration

cs-api-definition
protected override IEnumerable<Expression> CreateGroupKeyValuesExpressions(ParameterExpression itemExpression)

Parameters

itemExpression

ParameterExpression

The parameter expression, which will be used for grouping.

Returns

IEnumerable<Expression>

Value expressions.

Overrides QueryableGroupDescription.CreateGroupKeyValuesExpressions(ParameterExpression)

GetDisplayName()
