Syntax

public class PivotEditingManager

Constructors

PivotEditingManager(PivotGridControl)

Handles the event while editing the Pivot values.

Declaration

public PivotEditingManager(PivotGridControl pivotGrid)

Parameters

Type	Name	Description
PivotGridControl	pivotGrid	The PivotGrid control.

Properties

AllowEditingOfTotalCells

Gets or sets whether the user can edit total cells.

Declaration

public bool AllowEditingOfTotalCells { get; set; }

Property Value

Type	Description
System.Boolean

EditedCell

Gets or sets the edited cell row/column index.

Declaration

public RowColumnIndex EditedCell { get; set; }

Property Value

Type	Description
RowColumnIndex

HideExpanders

Gets or sets whether the expanders are visible.

Declaration

public bool HideExpanders { get; set; }

Property Value

Type	Description
System.Boolean

Methods

ChangeValue(Object, Object, Int32, Int32, PivotCellInfo)

Override this method to affect the change represented in the method arguments.

Declaration

protected virtual void ChangeValue(object oldValue, object newValue, int row1, int col1, PivotCellInfo pi)

Parameters

Type	Name	Description
System.Object	oldValue	The old value from the cell that was edited.
System.Object	newValue	The new value from the cell that was edited.
System.Int32	row1	Points to the row index of cell being adjusted. This cell may be different from the cell that was edited.
System.Int32	col1	Points to the column index of cell being adjusted. This cell may be different from the cell that was edited.
PivotCellInfo	pi	The PivotCellInfo for the cell being adjusted.

Remarks

The default implementation treats the adjustment as if the underlying calculation were a summation. This means the oldValue is subtracted from the cell being adjusted, and the new value is added. The adjustment is made by setting pi.Value and pi.FormattedText.

Examples

The following code shows the default implementation.

protected virtual void ChangeValue(object oldValue, object newValue, int row1, int col1, PivotCellInfo pi)
{
    double dNew = 0d;
    double dOld = 0d;
    double dExisting = 0d;
if (oldValue == null)
    oldValue = 0;
if (newValue == null)
    newValue = 0;
if (pi.Value == null)
    pi.Value = 0;

bool bNew = double.TryParse(newValue.ToString(), out dNew);
bool bOld = double.TryParse(oldValue.ToString(), out dOld);
bool bExisting = double.TryParse(pi.Value.ToString(), out dExisting);

if (bExisting)
{
    dExisting += (bNew ? dNew : 0) - (bOld ? dOld : 0);
}
else  
{
    dExisting = (bNew ? dNew : 0) - (bOld ? dOld : 0);
}
pi.Value = dExisting;
pi.FormattedText = string.Format("{0:" + pivotGrid.PivotEngine.PivotCalculations[col1 % pivotGrid.PivotEngine.PivotCalculations.Count].Format + "}", pi.Value);

}

Dispose()

Clears Undo/Redo lists and un-subscribes the events.

Declaration

public void Dispose()

GetRawItemsFor(Int32, Int32)

Gets a list of raw data items that go into computing the value, displayed in the given row and column.

Declaration

public List<object> GetRawItemsFor(int row, int col)

Parameters

Type	Name	Description
System.Int32	row	The row index.
System.Int32	col	The column index.

Returns

Type	Description
System.Collections.Generic.List<System.Object>	The list of data items associated with the given cell.

Remarks

If the row and column point to any cell other than a value cell, an list containing zero items is returned. If you are using a DataView as the underlying data source, the returned list contain DataRowView objects. If you are using an IList<object, then the return list will contain T objects."/>

GetRowColumnPivotValuesAt(Int32, Int32, out String)

Gets a list of row and column Pivot values at a specified index.

Declaration

public List<IComparable> GetRowColumnPivotValuesAt(int row, int column, out string calcFieldName)

Parameters

Type	Name	Description
System.Int32	row	The row index.
System.Int32	column	The column index.
System.String	calcFieldName	The name of the calculated field at the given row and column.

Returns

Type	Description
System.Collections.Generic.List<System.IComparable>	Returns a list of row and column Pivot values.

Remarks

The returned list is an ordered list of the Pivot values that determine the staring with the row Pivot values followed by the column Pivot values. There is a one to one correspondence between the number of items in PivotRows and then PivotColumns to this returned ordered list.

Redo()

Redoes the previously undone editing change.

Declaration

public void Redo()

Remarks

If a cell is actively being edited when this method is called, then the editing of that cell is cancelled. If there is no actively editing cell when this method is called, then the last undone editing action is restored.

SetCellValue(Int32, Int32, Object)

Sets the value of any specific cell dynamically from code behind. It will update the total cells automatically when the corresponding cell value is changing.

Declaration

public void SetCellValue(int row, int col, object newValue)

Parameters

Type	Name	Description
System.Int32	row	The row index.
System.Int32	col	The column index.
System.Object	newValue	The new value.

Undo()

Reverts the last editing change.

Declaration

public void Undo()

Remarks

If a cell is actively being edited when this method is called, then the editing of that cell is cancelled. If there is no actively editing cell when this method is called, then the last changed cell is reverted to its previous value.

Events

PivotValueEdited

Event raised as the user completes editing of a cell.

Declaration

public event PivotValueEditedEvent PivotValueEdited

Event Type

Type	Description
PivotValueEditedEvent
