Clone ( ) : object	Creates an exact copy of this cell.
DataGridViewAutoFilterMultiColumnHeaderCell ( ) : System	Initializes a new instance of the DataGridViewColumnHeaderCell class.
DataGridViewAutoFilterMultiColumnHeaderCell ( System.Windows.Forms.DataGridViewColumnHeaderCell oldHeaderCell ) : System	Initializes a new instance of the DataGridViewColumnHeaderCell class and sets its property values to the property values of the specified DataGridViewColumnHeaderCell.
GetFilterStatus ( System.Windows.Forms.DataGridView dataGridView ) : String	Gets a status string for the specified DataGridView indicating the number of visible rows in the bound, filtered BindingSource, or String.Empty if all rows are currently visible.
HideDropDownList ( ) : void	Hides the drop-down filter list.
RemoveFilter ( System.Windows.Forms.DataGridView dataGridView ) : void	Removes the filter from the BindingSource bound to the specified DataGridView.
ShowDropDownList ( ) : void	Displays the drop-down filter list.

메소드	설명
OnDataGridViewChanged ( ) : void	Called when the value of the DataGridView property changes in order to perform initialization that requires access to the owning control and column.
OnMouseDown ( System.Windows.Forms.DataGridViewCellMouseEventArgs e ) : void	Handles mouse clicks to the header cell, displaying the drop-down list or sorting the owning column as appropriate.
Paint ( Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState, object value, object formattedValue, string errorText, System.Windows.Forms.DataGridViewCellStyle cellStyle, System.Windows.Forms.DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts ) : void	Paints the column header cell, including the drop-down button.

비공개 메소드들

메소드	설명
AdjustPadding ( Int32 newDropDownButtonPaddingOffset ) : void	Adjusts the cell padding to widen the header by the drop-down button width.
CmdOk_Click ( object sender, EventArgs e ) : void
DataGridView_ColumnDisplayIndexChanged ( object sender, System.Windows.Forms.DataGridViewColumnEventArgs e ) : void	Invalidates the drop-down button bounds when the column display index changes.
DataGridView_ColumnHeadersHeightChanged ( object sender, EventArgs e ) : void	Invalidates the drop-down button bounds when the height of the column headers changes.
DataGridView_ColumnSortModeChanged ( object sender, System.Windows.Forms.DataGridViewColumnEventArgs e ) : void	Throws an exception when the column sort mode is changed to Automatic.
DataGridView_ColumnWidthChanged ( object sender, System.Windows.Forms.DataGridViewColumnEventArgs e ) : void	Invalidates the drop-down button bounds when a column width changes in the DataGridView control. A width change in any column of the control has the potential to affect the drop-down button location, depending on the current horizontal scrolling position and whether the changed column is to the left or right of the current column. It is easier to invalidate the button in all cases.
DataGridView_DataBindingComplete ( object sender, DataGridViewBindingCompleteEventArgs e ) : void	Invalidates the drop-down button bounds, hides the drop-down filter list, if it is showing, and resets the cached filter values if the filter has been removed.
DataGridView_DataSourceChanged ( object sender, EventArgs e ) : void	Verifies that the data source meets requirements, invalidates the drop-down button bounds, hides the drop-down filter list if it is showing, and resets the cached filter values if the filter has been removed.
DataGridView_Scroll ( object sender, ScrollEventArgs e ) : void	Invalidates the drop-down button bounds when the user scrolls horizontally.
DataGridView_SizeChanged ( object sender, EventArgs e ) : void	Invalidates the drop-down button bounds when the size of the DataGridView changes. This prevents a painting issue that occurs when the right edge of the control moves to the right and the control contents have previously been scrolled to the right.
DropDownListBox_KeyDown ( object sender, KeyEventArgs e ) : void	Handles the ENTER and ESC keys.
DropDownListBox_LostFocus ( object sender, EventArgs e ) : void	Hides the drop-down list when it loses focus.
HandleDataGridViewEvents ( ) : void	Add handlers to various DataGridView events, primarily to invalidate the drop-down button bounds, hide the drop-down list, and reset cached filter values when changes in the DataGridView require it.
HandleDropDownListBoxEvents ( ) : void	Adds handlers to ListBox events for handling mouse and keyboard input.
InvalidateDropDownButtonBounds ( ) : void	Sets dropDownButtonBoundsValue to Rectangle.Empty if it isn't already empty. This indicates that the button bounds should be recalculated.
PopulateFilters ( ) : void	Populates the filters dictionary with formatted and unformatted string representations of each unique value in the column, accounting for all filters except the current column's. Also adds special filter options.
RefreshDGV ( int currentRow ) : void	forces refreshing this tab
ResetDropDown ( ) : void	Invalidates the drop-down button bounds and hides the filter list if it is showing.
ResetFilter ( ) : void	Resets the cached filter values if the filter has been removed.
SetDropDownButtonBounds ( ) : void	Sets the position and size of dropDownButtonBoundsValue based on the current cell bounds and the preferred cell height for a single line of header text.
SetDropDownListBoxBounds ( ) : void	Sets the dropDownListBox.FilterListBox size and position based on the formatted values in the filters dictionary and the position of the drop-down button. Called only by ShowDropDownListBox.
SortByColumn ( ) : void	Sorts the DataGridView by the current column if AutomaticSortingEnabled is true.
UnhandleDropDownListBoxEvents ( ) : void	Removes the ListBox event handlers.
UpdateFilter ( ) : void	Updates the BindingSource.Filter value based on a user selection from the drop-down filter list.
VerifyDataSource ( ) : void	Confirms that the data source, if it has been set, is a BindingSource.
