Question

我有一个UltraGrid，其中包含几列，如下所示：

------------------------
| Name | Year | Audit  |
------------------------
| John | 2012 |[Button]|
------------------------
| Bill | 2013 |[Button]|
------------------------

我想在运行时使用键盘快捷键在所选行的审核列按钮上单击。那可能吗？像这样的东西（不存在）

myUltraGrid.ActiveRow.Cells("Audit").CellButton.PerformClick()

Answer 1

点击Button Style的单元格会触发事件ClickCellButton。此事件接收包含单击的单元格的CellEventArgs信息。您可以轻松地重构代码以分离在此事件中执行的操作，并使该操作可以从事件外部调用（无论何时需要执行操作）

' Your clickCellButton will be refactored to extract in a separate method '
' the action for every cell button'
Private Sub grd_ClickCellButton(sender as object, e as CellEventArgs)
    Try
        if e.Cell.Column.Key == "Audit" Then
            ActionForCellAudit(e.Cell.Row)
        elseif (e.Cell.Column.Key == "key2" Then
            ActionForCellButton1()
        elseif (e.Cell.Column.Key == "key3" Then
            ActionForCellButton1()
    Catch(a As Exception)
        MessageBox.Show(x.Message)
    End Try
End Sub

Private Sub ActionForCellAudit(row As UltraGridRow)
     ' The action required if clicking the Audit cell button is here'
End Sub
......

现在，当您需要在其他位置执行相同的操作时，您会提取有关ActiveRow的信息并调用ActionForCellAudit

Private Sub Form1_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) _
                          Handles Form1.KeyDown
    ' Supposing the CTRL+F5 is the shortcut defined to execute the ActionForCellAudit
    If e.KeyCode = Keys.F5 AndAlso e.Control = True then
        if grd.ActiveRow IsNot Nothing AndAlso grd.ActiveRow.IsDataRow Then
            ActionForCellAudit(grd.ActiveRow)
        End If
    End If
End Sub

以编程方式在超网格单元格中执行单击
