    T value

    Clear()

    Clears out the dictionary. There are no "OnRemoveCell" notfications triggered.

    Declaration
    public void Clear()

    Clear(RowColumnIndex)

    Removes the cell from the dictionary. There is no "OnRemoveCell" callback triggered.

    Declaration
    public bool Clear(RowColumnIndex cell)
    Parameters
    Type Name Description
    RowColumnIndex cell
    Returns
    Type
    System.Boolean

    ContainsKey(RowColumnIndex)

    Determines whether a cell exists.

    Declaration
    public bool ContainsKey(RowColumnIndex cell)
    Parameters
    Type Name Description
    RowColumnIndex cell

    The cell.

    Returns
    Type Description
    System.Boolean

    true if the cell exists; otherwise, false.

    GetEnumerator()

    Returns an enumerator that iterates through the collection.

    Declaration
    public IEnumerator<KeyValuePair<RowColumnIndex, T>> GetEnumerator()
    Returns
    Type Description
    System.Collections.Generic.IEnumerator<System.Collections.Generic.KeyValuePair<RowColumnIndex, T>>

    A enumerator that can be used to iterate through the collection.

    InsertColumns(Int32, Int32, RowColumnIndexValueDictionary<T>)

    Inserts the columns and calls OnMovedCell(RowColumnIndex, T) callback for each moved cell. When you specify moveCells then these cells will be added beginning at the first insert column.

    Declaration
    public void InsertColumns(int insertAtColumnIndex, int count, RowColumnIndexValueDictionary<T> moveCells)
    Parameters
    Type Name Description
    System.Int32 insertAtColumnIndex

    Index of the insert at column.

    System.Int32 count

    The count.

    RowColumnIndexValueDictionary<T> moveCells

    The move cells.

    InsertRows(Int32, Int32, RowColumnIndexValueDictionary<T>)

    Inserts the rows and calls OnMovedCell(RowColumnIndex, T) callback for each moved cell. When you specify moveCells then these cells will be added beginning at the first insert row.

    Declaration
    public void InsertRows(int insertAtRowIndex, int count, RowColumnIndexValueDictionary<T> moveCells)
    Parameters
    Type Name Description
    System.Int32 insertAtRowIndex

    Index of the insert at row.

    System.Int32 count

    The count.

    RowColumnIndexValueDictionary<T> moveCells

    The move cells.

    OnMovedRow(KeyValuePair<Int32, IntegerValueCellsDictionary<T>>, Int32)

    Called when a row was moved. The default implementation of this method loops through all cells in the row and calls OnMovedCell(RowColumnIndex, T) for each cell.

    Declaration
    protected virtual void OnMovedRow(KeyValuePair<int, IntegerValueCellsDictionary<T>> rowEntry, int rowIndex)
    Parameters
    Type Name Description
    System.Collections.Generic.KeyValuePair<System.Int32, IntegerValueCellsDictionary<T>> rowEntry

    The row entry.

    System.Int32 rowIndex

    Index of the row.

    OnRemovedRow(KeyValuePair<Int32, IntegerValueCellsDictionary<T>>)

    Called when row was removed. The default implementation of this method loops through all cells in the row and calls OnRemoveCell(RowColumnIndex, T) for each cell.

    Declaration
    protected virtual void OnRemovedRow(KeyValuePair<int, IntegerValueCellsDictionary<T>> rowEntry)
    Parameters
    Type Name Description
    System.Collections.Generic.KeyValuePair<System.Int32, IntegerValueCellsDictionary<T>> rowEntry

    The row entry.

    Remove(GridRangeInfo)

    Removes the specified cell span and calls OnRemoveCell(RowColumnIndex, T) callback for each deleted cell.

    Declaration
    public void Remove(GridRangeInfo cellSpan)
    Parameters
    Type Name Description
    GridRangeInfo cellSpan

    The cell span.

    Remove(RowColumnIndex)

    Removes the cell from the dictionary and calls OnRemoveCell(RowColumnIndex, T) callback for the deleted cell.

    Declaration
    public bool Remove(RowColumnIndex cell)
    Parameters
    Type Name Description
    RowColumnIndex cell
    Returns
    Type
    System.Boolean

    RemoveAll()

    Removes all entries from the dictionary and calls OnRemoveCell(RowColumnIndex, T) callback for each deleted cell.

    Declaration
    public virtual void RemoveAll()

    RemoveColumns(Int32, Int32, RowColumnIndexValueDictionary<T>)

    Removes the columns and calls OnRemoveCell(RowColumnIndex, T) callback for each removed cell. When you specify moveCells the callback will not be called, instead the cells will be added to the moveCells dictionary. A subsequent InsertColumns call can then insert the columns at a different location.

    Declaration
    public void RemoveColumns(int removeAtColumnIndex, int count, RowColumnIndexValueDictionary<T> moveCells)
    Parameters
    Type Name Description
    System.Int32 removeAtColumnIndex

    Index of the remove at column.

    System.Int32 count

    The count.

    RowColumnIndexValueDictionary<T> moveCells

    The move cells.

    RemoveRows(Int32, Int32, RowColumnIndexValueDictionary<T>)

    Removes the rows and calls OnRemoveCell(RowColumnIndex, T) callback for each removed cell. When you specify moveCells the callback will not be called, instead the cells will be added to the moveCells dictionary. A subsequent InsertRows call can then insert the rows at a different location.

    Declaration
    public void RemoveRows(int removeAtRowIndex, int count, RowColumnIndexValueDictionary<T> moveCells)
    Parameters
    Type Name Description
    System.Int32 removeAtRowIndex

    Index of the remove at row.

    System.Int32 count

    The count.

    RowColumnIndexValueDictionary<T> moveCells

    The move cells.

    SetCallback(IRowColumnIndexValueDictionaryCallbacks<T>)

    Sets the callback.

    Declaration
    public void SetCallback(IRowColumnIndexValueDictionaryCallbacks<T> callback)
    Parameters
    Type Name Description
    IRowColumnIndexValueDictionaryCallbacks<T> callback

    The callback.

    TryGetValue(RowColumnIndex, out T)

    Tries to get the value if the cell exists.

    Declaration
    public bool TryGetValue(RowColumnIndex cell, out T value)
    Parameters
    Type Name Description
    RowColumnIndex cell

    The cell.

    T value

    The value.
