Methods

GetFormattedValue

protected override object GetFormattedValue(object value, int rowIndex, ref DataGridViewCellStyle cellStyle, System.ComponentModel.TypeConverter valueTypeConverter, System.ComponentModel.TypeConverter formattedValueTypeConverter, DataGridViewDataErrorContexts context)

Formats the cell's value for display, in the pattern and culture its column names.

The column's Format, CustomFormat and BinaryCultureInfo used to reach the editing control and nothing else, so every row that was not being edited showed its value as ToString() - a date with midnight after it, cut off in any column narrow enough to look right (HANDOVER 3av). A Format set on the cell's style still wins, as it does for any other cell.

InitializeEditingControl

public override void InitializeEditingControl(int rowIndex, object initialFormattedValue, DataGridViewCellStyle dataGridViewCellStyle)

Prepares the editing control that this cell hands to the grid, pushing the cell's own settings onto it before editing starts.

Paint

protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState, object value, object formattedValue, string errorText, DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts)

Paints this cell. The base implementation draws the standard cell; this override adds the parts specific to BinaryTreeListViewDatePickerCell.

With SpecialColumnCellsToDisplayEditingControlOnCellsAlways on, a row that is not being edited shows the picker's drop-down button beside its date: flat - a chevron, in a hairline box when the column's ShowBorderAlways is on - while DrawStyleIsFlat is on, and the classic themed push button otherwise (HANDOVER 3av).
