Grid Column Style. Commit(CurrencyManager, Int32) Method
When overridden in a derived class, initiates a request to complete an editing procedure.
protected public: abstract bool Commit(System::Windows::Forms::CurrencyManager ^ dataSource, int rowNum);
protected internal abstract bool Commit (System.Windows.Forms.CurrencyManager dataSource, int rowNum);
abstract member Commit : System.Windows.Forms.CurrencyManager * int -> bool
Protected Friend MustOverride Function Commit (dataSource As CurrencyManager, rowNum As Integer) As Boolean
The number of the row being edited.
true if the editing procedure committed successfully; otherwise,
The following code example shows a possible override of the Commit method. The code invokes the SetColumnValueAtRow method, and then sets a variable that allows other functions to determine whether the column is still in edit more. The code then calls the Invalidate method to redraw the control. Finally, the function returns
true to indicate the change has been committed.
Protected Overrides Function Commit(dataSource As System.Windows.Forms.CurrencyManager, rowNum As Integer) As Boolean SetColumnValueAtRow(dataSource, rowNum, currentValue) isEditing = False Invalidate Commit = True End Function
Notes to Implementers
The Commit(CurrencyManager, Int32) method should be used by classes derived from the DataGridColumnStyle class to reset their editing state, for example, to concede the focus if the DataGridColumnStyle hosts an editing control. See the ConcedeFocus() method.
The Commit(CurrencyManager, Int32) method is called by the public method OnMouseDown(MouseEventArgs) of the DataGrid control. The method is also called by other private methods, for example, when the current row is changed.
