C# Class Habanero.Faces.Win.EditableGridWin

Provides a grid on which the user can edit data and add new business objects directly.
IMPORTANT: This grid does not provide any buttons or menus for users to save the changes they have made, and all changes will be lost if the form is closed and changes are not saved programmatically. Either carry out a dirty check when the parent form is closed and take appropriate save action using SaveChanges(), or use an IEditableGridControl, which provides Save and Cancel buttons.

Inheritance: GridBaseWin, IEditableGrid

Méthodes publiques

Méthode	Description
CellClickHandler ( object sender, System.Windows.Forms.DataGridViewCellEventArgs e ) : void	Carries out additional actions when a cell is clicked. Specifically, if a combobox cell is clicked, the cell goes into edit mode immediately.
CheckIfComboBoxShouldSetToEditMode ( int columnIndex, int rowIndex ) : bool	Checks whether this is a comboboxcolumn and whether it should begin edit immediately (to circumvent the pain of having to click a cell multiple times to edit the value). This method is typically called by the cell click handler. This method was extracted from the handler in order to make testing possible, since calling BeginEdit at testing time causes an STA thread error.
CreateDataSetProvider ( IBusinessObjectCollection col ) : IDataSetProvider	Creates a dataset provider that is applicable to this grid. For example, a readonly grid would return a read only datasetprovider, while an editable grid would return an editable one.
DeleteKeyHandler ( ) : void	Carries out actions when the delete key on the keyboard is pressed
EditableGridWin ( ) : System	Constructs the EditableGridWin
RejectChanges ( ) : void	Restore the objects in the grid to their last saved state
SaveChanges ( ) : void	Saves the changes made to the data in the grid
