Bypass read only cells in DataGridView when pressing TAB key

Question

Can anyone show me some code of how I could bypass read only cells in DatagridView when pressing TAB key?

Answer 1

When the cell is in edit mode, and you want to listen to keystroke events, you might try handling the DataGridView's EditingControlShowing event...

Private Sub myDvGrid_EditingControlShowing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles myDvGrid.EditingControlShowing
    Dim c As DataGridViewTextBoxEditingControl = DirectCast(e.Control, DataGridViewTextBoxEditingControl)

    RemoveHandler c.PreviewKeyDown, AddressOf edtctrlOn_PreviewKeyDown
    RemoveHandler c.TextChanged, AddressOf edtctrlOn_TextChanged

    AddHandler c.TextChanged, AddressOf edtctrlOn_TextChanged
    AddHandler c.PreviewKeyDown, AddressOf edtctrlOn_PreviewKeyDown

End Sub

Then, in the edtctrlOn_PreviewKeyDown event, you can bubble the arguments over to the original datagrid's PreviewKeyDown event handler.
