    Classes

    DefaultLineSizeChangedEventArgs
    DistanceCounterCollection

    A collection of entities for which distances need to be counted. The collection provides methods for mapping from a distance position to an entity and vice versa.

    For example, in a scrollable grid control you have rows with different heights. Use this collection to determine the total height for all rows in the grid, quickly detemine the row index for a given point and also quickly determine the point at which a row is displayed. This also allows a mapping between the scrollbars value and the rows or columns associated with that value.

    DistanceCounterSubset

    A collection of entities that is shared with a parent collection for which distances need to counted. The collection only is a subset for a specific range in the parent distance collection.

    When you change the size of an element in this collection the change will also be reflected in the parent collection and vice versa.

    DistanceRangeCounterCollection

    A collection of entities for which distances need to be counted. The collection provides methods for mapping from a distance position to an entity and vice versa.

    For example, in a scrollable grid control you have rows with different heights. Use this collection to determine the total height for all rows in the grid, quickly detemine the row index for a given point and also quickly determine the point at which a row is displayed. This also allows a mapping between the scrollbars value and the rows or columns associated with that value.

    EmptyLineSizeCollection

    An empty LineSizeCollection.

    EmptyLineSizeHost

    Implements the ILineSizeHost interface for an empty collection that cannot be modified.

    HiddenRangeChangedEventArgs

    Holds From and To integer properties.

    LineScrollAxis

    The LineScrollAxis implements scrolling only for whole lines. You can hide lines and LineScrollAxis provides a mapping mechanism between the index of the line and the scroll index and vice versa. Hidden lines are not be counted when the scroll index is determined for a line.

    The LineScrollAxis does not support scrolling in between lines (pixel scrolling). This can be of advantage if you have a large number of lines with varying line sizes. In such case the LineScrollAxis does not need to maintain a collection that tracks line sizes whereas the PixelScrollAxis does need to.

    LinesInsertedEventArgs

    Holds InsertAt and Count integer properties.

    LineSizeCollection

    A collection that manages lines with varying height and hidden state. It has properties for header and footer lines, total line count, default size of a line and also lets you add nested collections.

    LineSizeUtil
    LinesRemovedEventArgs

    Holds RemoveAt and Count integer properties.

    PixelScrollAxis

    PixelScrollAxis implements scrolling logic for both horizontal and vertical scrolling in a ScrollAxisBase. Logical units in the ScrollAxisBase are called "Lines".

    PixelScrollAxis supports pixel scrolling and calculates the total height or width of all lines.

    RangeChangedEventArgs

    Holds From and To integer properties.

    RangeValuePair<T>

    Holds a range together with a value assigned to the range.

    ScrollAxisBase

    ScrollAxisBase is an abstract base class and implements scrolling logic for both horizontal and vertical scrolling in a ScrollAxisBase. Logical units in the ScrollAxisBase are called "Lines".

    ScrollAxisBase has support for frozen header and footer lines, maintaining a scroll position and updating and listening to scrollbars. It also maintains a collection of VisibleLineInfo items for all the lines that are visible in the viewing area. ScrollAxisBase wires itself with a ScrollLinesHost and reacts to changes in line count, line sizes, hidden state and default line size.

    ScrollChangedEventArgs
    ScrollInfo

    Provides all properties to configure a scrollbar.

    SortedRangeValueList<T>

    A sorted list with RangeValuePair<T> ordered by the start index of the ranges. SortedRangeValueList ensures that ranges of the elements inside the list do not overlap and it also ensures that there are no empty gaps meaning that the subsequent range will always have the Start position be set to the End position of the previous range plus one.

    ValueChangingEventArgs

    Holds NewValue and OldValue properties.

    VisibleLineInfo

    Contains information about a visible line (can also be a row or column).

    VisibleLinesCollection

    A strong-typed collection of VisibleLineInfo items.

    Structs

    RowColumnIndex

    Holds the coordinates for a cell.

    Interfaces

    IDistanceCounterCollection

    A collection of entities for which distances need to counted. The collection provides methods for mapping from a distance position to an entity and vice versa.

    For example, in a scrollable grid control you have rows with different heights. Use this collection to determine the total height for all rows in the grid, quickly detemine the row index for a given point and also quickly determine the point at which a row is displayed. This also allows a mapping between the scrollbars value and the rows or columns associated with that value.

    IDistancesHost

    An object that implements the Distances property.

    IEditableLineSizeHost

    A collection that manages lines with varying height and hidden state. It has properties for header and footer lines, total line count, default size of a line and also lets you add nested collections. Methods are provided for changing the values and getting the total extent.

    ILineSizeHost

    A collection that manages lines with varying height and hidden state. It has properties for header and footer lines, total line count, default size of a line and also lets you add nested collections.

    INestedDistancesHost

    An object that implements the GetDistances(Int32) method.

    IPaddedEditableLineSizeHost
    IScrollBar

    Defines an interface that provides all properties to configure a scrollbar.

    Enums

    CornerSide

    Corner side enumeration.

    ScrollAxisRegion

    A scroll axis has three regions: Header, Body and Footer.

    ScrollChangedAction

    Delegates
