Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The following code example illustrates how to handle this event for a DataGridView control in virtual mode. When the control is in edit mode, the rowInEdit variable holds the index of the row being edited, and the customerInEdit variable holds a reference to a Customer object corresponding to that row. When the user cancels out of edit mode, this object can be discarded. If the row the user was editing is the row for new records, however, the old Customer object is discarded and replaced with a new one so that the user can begin making edits again. This example is part of a larger example available in Walkthrough: Implementing Virtual Mode in the Windows Forms DataGridView Control.
Private Sub dataGridView1_CancelRowEdit(ByVal sender As Object, _ ByVal e As System.Windows.Forms.QuestionEventArgs) _ Handles dataGridView1.CancelRowEdit If Me.rowInEdit = Me.dataGridView1.Rows.Count - 2 AndAlso _ Me.rowInEdit = Me.customers.Count Then ' If the user has canceled the edit of a newly created row, ' replace the corresponding Customer object with a new, empty one. Me.customerInEdit = New Customer() Else ' If the user has canceled the edit of an existing row, ' release the corresponding Customer object. Me.customerInEdit = Nothing Me.rowInEdit = -1 End If End Sub
