Syntax

public class GridModelFloatingCells : GridModelBound, IDisposable, ISerializable

Remarks

You access this class from a grid with the FloatingCells property of a GridModel instance.

Covered ranges are saved in two separate collections.

The first collection is GridRangeInfoList, which allows quick enumeration through all covered cell ranges in the grid. This is good when covered ranges need to be recalculated because rows or column have been inserted, moved, or removed.

The second collection is GridCoveredCellPool, which is optimized to look up if a specific cell is part of a covered range.

The QueryCoveredRange event in a GridModel lets you provide customized covered cells ranges at run-time. For example, you might want to have a pattern of covered ranges. This allows you to customize the grid's default behavior and manage covered ranges by your own code and not with the GridModelCoveredRanges class.

Constructors

GridModelFloatingCells(GridModel)

Initializes a new instances ofGridModelFloatingCells class and associates it with a GridModel.

Declaration

public GridModelFloatingCells(GridModel model)

Parameters

Type	Name	Description
GridModel	model	A reference to the parent GridModel.

GridModelFloatingCells(SerializationInfo, StreamingContext)

Initializes a new instances ofGridModelFloatingCells from a serialization stream.

Declaration

protected GridModelFloatingCells(SerializationInfo info, StreamingContext context)

Parameters

Type	Name	Description
System.Runtime.Serialization.SerializationInfo	info	An object that holds all the data needed to serialize or de-serialize this instance.
System.Runtime.Serialization.StreamingContext	context	Describes the source and destination of the serialized stream specified by info.

Methods

DelayFloatCells(GridRangeInfo)

Marks the specified range of cells to be re-evaluated at a later time if text is floating into neighboring cells.

Declaration

public void DelayFloatCells(GridRangeInfo range)

Parameters

Type	Name	Description
GridRangeInfo	range	The range to be re-evaluated.

Dispose(Boolean)

Disposes the unmanaged resources.

Declaration

protected override void Dispose(bool disposing)

Parameters

Type	Name	Description
System.Boolean	disposing

Overrides

GridModelBound.Dispose(Boolean)

EvaluateFloatingCells(GridRangeInfo)

Determines the specified range to see if any cells have been previously marked with DelayFloatCells(GridRangeInfo) to be re-evaluated.

Declaration

public bool EvaluateFloatingCells(GridRangeInfo range)

Parameters

Type	Name	Description
GridRangeInfo	range	The range to be re-evaluated.

Returns

Type	Description
System.Boolean	True if floating state for any cell in the given range was changed.

Find(Int32, Int32, out GridRangeInfo)

Determines a GridRangeInfo object that indicates the floating cell's range for the specified cell position or False if there is no floating cell's range for the given cell position.

Declaration

public bool Find(int rowIndex, int colIndex, out GridRangeInfo range)

Parameters

Type	Name	Description
System.Int32	rowIndex	The row index.
System.Int32	colIndex	The column index.
GridRangeInfo	range	The GridRangeInfo where the found floating cell's range is returned.

Returns

Type	Description
System.Boolean	True if a floating cell's range is at the specified cell position; False if not.

FindRange(Int32, Int32)

Returns a GridRangeInfo object that indicates the floating cell's range for the specified cell position or Empty if there is no floating cell's range for the given cell position.

Declaration

public GridRangeInfo FindRange(int rowIndex, int colIndex)

Parameters

Type	Name	Description
System.Int32	rowIndex	The row index.
System.Int32	colIndex	The column index.

Returns

Type	Description
GridRangeInfo	A reference to range if a floating cell's range is at the specified cell position or Empty if not.

LockEvaluate()

Determines whether temporarily stop evaluating floating cells.

Declaration

public bool LockEvaluate()

Returns

Type	Description
System.Boolean	returns True.

Merge(GridRangeInfo)

Combines all floating cell's ranges that intersect with a specified into one outer range that spans over all found ranges.

Declaration

public GridRangeInfo Merge(GridRangeInfo range)

Parameters

Type	Name	Description
GridRangeInfo	range	The original range.

Returns

Type	Description
GridRangeInfo	The GridRangeInfo with the outer range.

UnlockEvaluate()

Start evaluating floating cells again after LockEvaluate call.

Declaration

public void UnlockEvaluate()

Explicit Interface Implementations

ISerializable.GetObjectData(SerializationInfo, StreamingContext)

Implements the ISerializable interface and returns the data needed to serialize the GridModelFloatingCells.

Declaration

void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)

Parameters

Type	Name	Description
System.Runtime.Serialization.SerializationInfo	info	A SerializationInfo object containing the information required to serialize the object.
System.Runtime.Serialization.StreamingContext	context	A StreamingContext object containing the source and destination of the serialized stream.

Implements

System.IDisposable

System.Runtime.Serialization.ISerializable
