Namespace Syncfusion.GridCommon.ScrollAxis

Classes

CornerSide Corner side enumeration.

DefaultLineSizeChangedEventArgs Provides data for the DefaultLineSizeChanged event.

DefaultLineSizeChangedEventHandler Delegate for handling the DefaultLineSizeChanged event.

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 determine 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.

EmptyLineSizeCollection An empty LineSizeCollection.

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

HiddenRangeChangedEventArgs Provides data for the LineHiddenChanged event.

HiddenRangeChangedEventHandler Delegate for the LineHiddenChanged event.

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 Provides data for the LinesInserted event.

LinesInsertedEventHandler Delegate that handles the LinesInserted event.

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.

LinesRemovedEventArgs Provides data for the LinesRemoved event.

LinesRemovedEventHandler Delegate that handles the LinesRemoved event.

PixelScrollAxis PixelScrollAxis implements scrolling logic for both horizontal and vertical scrolling in a Distances. Logical units in the ScrollAxisBase are called "Lines". With the Distances a line represents rows in a grid and with Distances a line represents columns in a grid. PixelScrollAxis supports pixel scrolling and calculates the total height or width of all lines.

RangeChangedEventArgs Provides data for the LineSizeChanged event.

RangeChangedEventHandler Delegate that handles the LineSizeChanged event.

RangeValuePair<T> Holds a range together with a value assigned to the range.

RowColumnIndex Holds the coordinates for a cell.

ScrollAxisBase ScrollAxisBase is an abstract base class and implements scrolling logic for both horizontal and vertical scrolling in a Distances. Logical units in the ScrollAxisBase are called "Lines". With the Syncfusion.GridCommon.ScrollAxis.PixelScrollAxis.distances a line represents rows in a grid and with Distances a line represents columns in a grid. 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.

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

ScrollChangedAction Defines the various constants for the scroll changed action.

ScrollChangedEventArgs Provides data for the Changed event.

ScrollChangedEventHandler Delegate that handles the Changed event.

ScrollInfo Provides all properties to configure a scrollbar.

ValueChangingEventArgs Provides data for the ValueChanging event.

ValueChangingEventHandler Delegate that handles the ValueChanging event.

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

VisibleLinesCollection A strong-typed collection of VisibleLineInfo items.

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 determine 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 An object that implements the PaddingDistance property and DeferRefresh() method.

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