How Can i detect <Return> in datagrid Cell
-
Hi, Please I need help. I created a form that allows me searching customers by name. after display customers list in datagrid, i want allow user to select one customer by pressing key. for grid setup, i tried the following code : 'Configuration de la grille Private Sub DataGridSetup() Dim ts As New DataGridTableStyle() Dim cs As New DataGridTextBoxColumn() AddHandler cs.TextBox.KeyPress, AddressOf CellKeyPress DataGrid1.ContextMenu = ContextMenu1 DataGrid1.CaptionText = "Résultat" ts.MappingName = "mycli" cs.MappingName = "c_cli" cs.HeaderText = "Code" cs.Alignment = HorizontalAlignment.Center ts.GridColumnStyles.Add(cs) cs = New DataGridTextBoxColumn() cs.MappingName = "N_cli" cs.HeaderText = "Nom/Raison sociale" ts.GridColumnStyles.Add(cs) DataGrid1.TableStyles.Clear() DataGrid1.TableStyles.Add(ts) End Sub and i added handler to datagridtextboxcolumn, for detecting the keypress events as follows : 'Ajout d'un évènement aux cellules Public Sub CellKeyPress(ByVal Sender As Object, ByVal e As KeyPressEventArgs) Dim dt As DataTable = ds.Tables("mycli") Dim p As Integer CodeClient = Space(11) If e.KeyChar = Chr(13) Then p = Me.BindingContext(ds, "mycli").Position CodeClient = dt.Rows(p)("c_cli") Me.Close() End If End Sub So after writing this code, i can select one customer only after pressing SHIFT+RETURN. please can you explain me way i must first press SHIFT. Thank you very match. * * * * *

KeyDowninstead of the KeyPress event, then useKeyCodeinstead of the KeyChar. It should work then Notorious SMC
