Public Methods

Method	Description
FwTextBoxCell ( ) : System	Initializes a new instance of the T:FwTextBoxCell class.
InitializeEditingControl ( int rowIndex, object initialFormattedValue, System.Windows.Forms.DataGridViewCellStyle dataGridViewCellStyle ) : void	Attaches and initializes the hosted editing control.
ParseFormattedValue ( object formattedValue, System.Windows.Forms.DataGridViewCellStyle cellStyle, TypeConverter formattedValueTypeConverter, TypeConverter valueTypeConverter ) : object	Get the ITsString Get the ITsString from the text box control rather than trying to parse/convert it from the string - there is no type converter that could do it and we would need to know the writing system etc. NOTE: formattedValue contains either the new value or the previous value (if the user cancels). This solution always returns the new value. However, this is currently not a problem because Cancel is handled by the dialog.

Protected Methods

Method	Description
GetFormattedValue ( object value, int rowIndex, System.Windows.Forms.DataGridViewCellStyle &cellStyle, TypeConverter valueTypeConverter, TypeConverter formattedValueTypeConverter, DataGridViewDataErrorContexts context ) : object	Gets the text value of the cell's TsString and uses it as the value to display.
Paint ( Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState, object val, object formattedValue, string errorText, System.Windows.Forms.DataGridViewCellStyle cellStyle, System.Windows.Forms.DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts ) : void	Paint this DataGridView cell. Overridden to allow RightToLeft display if needed.

Private Methods

Method	Description
DrawFwText ( Graphics graphics, Rectangle cellBounds, string text, System.Windows.Forms.DataGridViewCellStyle cellStyle, FwTextBoxColumn col ) : void	Draw the text using the FieldWorks IVwGraphicsWin32 interface.
GetLocationForText ( Rectangle cellBounds, bool fRightToLeft, IVwGraphicsWin32 vg, string text, int &x, int &y ) : void	Get the starting location for drawing the text.
GetRenderProps ( System.Windows.Forms.DataGridViewCellStyle cellStyle, FwTextBoxColumn col ) : LgCharRenderProps
InitializeTextBoxControl ( SIL.FieldWorks.Common.Widgets.FwTextBoxControl ctrl, int rowIndex ) : void	Initializes the text box control. rowIndex is usually the same as RowIndex, except in the case of a shared row (in which case RowIndex is always -1).

Method Details

FwTextBoxCell() public method

Initializes a new instance of the T:FwTextBoxCell class.

public FwTextBoxCell ( ) : System
return	System

GetFormattedValue() protected method

Gets the text value of the cell's TsString and uses it as the value to display.

Formatting failed and either there is no /// handler for the event /// of the control or the /// handler set the /// property to true. The exception object can typically be cast to type /// .

protected GetFormattedValue ( object value, int rowIndex, System.Windows.Forms.DataGridViewCellStyle &cellStyle, TypeConverter valueTypeConverter, TypeConverter formattedValueTypeConverter, DataGridViewDataErrorContexts context ) : object
value	object	The value to be formatted.
rowIndex	int	The index of the cell's parent row.
cellStyle	System.Windows.Forms.DataGridViewCellStyle	The /// in effect for the cell.
valueTypeConverter	System.ComponentModel.TypeConverter	A /// associated with the value type that provides custom conversion to the formatted value /// type, or null if no such custom conversion is needed.
formattedValueTypeConverter	System.ComponentModel.TypeConverter	A /// associated with the formatted value type that provides custom conversion from the value /// type, or null if no such custom conversion is needed.
context	DataGridViewDataErrorContexts	A bitwise combination of /// values describing /// the context in which the formatted value is needed.
return	object

InitializeEditingControl() public method

Attaches and initializes the hosted editing control.

public InitializeEditingControl ( int rowIndex, object initialFormattedValue, System.Windows.Forms.DataGridViewCellStyle dataGridViewCellStyle ) : void
rowIndex	int	The index of the row being edited.
initialFormattedValue	object	The initial value to be displayed in the /// control.
dataGridViewCellStyle	System.Windows.Forms.DataGridViewCellStyle	A cell style that is used to determine the /// appearance of the hosted control.
return	void

Paint() protected method

Paint this DataGridView cell. Overridden to allow RightToLeft display if needed.

protected Paint ( Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState, object val, object formattedValue, string errorText, System.Windows.Forms.DataGridViewCellStyle cellStyle, System.Windows.Forms.DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts ) : void
graphics	System.Drawing.Graphics
clipBounds	System.Drawing.Rectangle
cellBounds	System.Drawing.Rectangle
rowIndex	int
cellState	DataGridViewElementStates
val	object
formattedValue	object
errorText	string
cellStyle	System.Windows.Forms.DataGridViewCellStyle
advancedBorderStyle	System.Windows.Forms.DataGridViewAdvancedBorderStyle
paintParts	DataGridViewPaintParts
return	void

ParseFormattedValue() public method

Get the ITsString

Get the ITsString from the text box control rather than trying to parse/convert it from the string - there is no type converter that could do it and we would need to know the writing system etc. NOTE: formattedValue contains either the new value or the previous value (if the user cancels). This solution always returns the new value. However, this is currently not a problem because Cancel is handled by the dialog.

public ParseFormattedValue ( object formattedValue, System.Windows.Forms.DataGridViewCellStyle cellStyle, TypeConverter formattedValueTypeConverter, TypeConverter valueTypeConverter ) : object
formattedValue	object	The display value of the cell.
cellStyle	System.Windows.Forms.DataGridViewCellStyle	The /// in effect for the cell.
formattedValueTypeConverter	System.ComponentModel.TypeConverter	A /// for the display value type, or null to use the default converter.
valueTypeConverter	System.ComponentModel.TypeConverter	A /// for the cell value type, or null to use the default converter.
return	object
