Question

我在Windows窗体中有一个DataGridView，当我按下右箭头键时，光标出现在下一个单元格上。但是当我按下TAB时，选择会改变，但光标不会出现在下一个单元格上，而我真正想要的是让这个光标以某种方式出现。我认为这将是一个解决方案，当用户在某些ComboBox / TextBox单元格中单击TAB时，可以使用TAB模拟右箭头单击。我在Windows窗体代码中实际拥有的一些Subs：

Private Sub DataGridView1_CellMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles DataGridView1.CellMouseClick
    sender.BeginEdit(True)
End Sub

Private Sub DataGridView1_SelectionChanged(sender As Object, e As EventArgs) Handles DataGridView1.SelectionChanged
    sender.BeginEdit(True)
End Sub

Private Sub DataGridView1EditingControlShowing(sender As Object, e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
    If IsComboBoxCell(DataGridView1.CurrentCell) Then
        Dim cb As ComboBox = TryCast(e.Control, ComboBox)
        If cb IsNot Nothing Then
            cb.DropDownStyle = ComboBoxStyle.DropDown
            cb.DropDownHeight = 200
            cb.AutoCompleteSource = Windows.Forms.AutoCompleteSource.ListItems
            cb.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.SuggestAppend
            RemoveHandler cb.Validated, AddressOf cb_Validated
            AddHandler cb.Validated, AddressOf cb_Validated
        End If
    End If
End Sub

Private Sub cb_Validated(sender As Object, e As EventArgs)
    Dim selectedItem = CType(sender, ComboBox).SelectedItem
    Dim col = CType(DataGridView1.Columns(DataGridView1.CurrentCell.ColumnIndex), DataGridViewComboBoxColumn)
    If String.IsNullOrEmpty(col.ValueMember) Then
        DataGridView1.CurrentCell.Value = selectedItem

    End If
End Sub

它适用于Enter但不适用于TAB。有可能吗？用户按下TAB，但它会像右箭头或其他解决方案一样触发？

检查您的＆＃34; StandardTab＆＃34;属性未设置为＆＃34; true＆＃34;

如果它不起作用（我不知道为什么）尝试处理密钥

 private void Data_KeyUp(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Tab)
            SendKeys.Send("{RIGHT}");
    }

对于c＃代码的sory，但我想你很容易在vb中写它

TAB单击移动到下一个datagridview单元格但不显示光标
