Question

我几天来一直在努力解决这个困难。我已经阅读了http://www.ironpython.info/并预订了Michael和Christian的'IronPython In Action'，以及https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview(v=vs.110).aspx上的DataGridView类，但我仍然缺乏一些知识和技能。我的问题是如何从一键按下获得价值，但没有按下'Enter'并移动到下一个单元格，这意味着当我在键盘上按一个数字但没有按下'Enter'时，数字将被传递到第一个单元格，如3，然后下一个单元格是活动的。序列是曲折的，如第1行第1列 - >第1行第2行 - ＆gt; ... - ＆gt;第1行第12行 - ＆gt;第2行第12行 - ＆gt;第2行第11行。我尝试过很多DataGridView事件，比如'CellEnter'和'KeyPress'，但都失败了。如果你能给出一些提示，我会非常感激。以下是我的代码：

Answer 1

我终于自己解决了这个问题。使用KeyPress事件并将ReadOnly属性设置为true。

Answer 2

我发现EditingControlShowing唤起一个事件，而self.dgv.CurrentCell = self.dgv.Rows [currentRow] .Cells [currentCol + 1]移动单元格。但是，我无法获取输入数字，表格为无。我的这部分代码如下。

android:fillViewport="true

Answer 3

我找到了一种方法：首先通过“self.dgv.EditingControlShowing + = self.keyPress”唤起EditingControlShowing事件;然后唤起KeyPress def keyPress（self，sender，event）： event.Control.KeyPress + = self.move 现在我可以通过“self.dgv.CurrentCell.Value = event.KeyChar”获得价值。但是，单元格值和移动并不总是正确的，需要解决。
