双击listview =单击按钮

标签： winforms powershell-v3.0 listviewitem double-click

我在Powershell中有一个带有2个按钮的Windows窗体和一个包含2个列“Nomducollège”（$ col1）和“Adresse IP”（$ col2）的列表视图。

列表视图由遍历$ MaListe的函数“AddData”填充。

如果我在列表视图中选择了一个lign并单击“连接器”（$ btnCo）按钮，则会出现第二个Windows窗体。

我正在寻找一种方法，当我双击listview的一行时，它会启动Connect按钮事件。

我自愿删除了Connect按钮事件，因为有许多行，但如果您希望我可以提供它。

这是我的代码：

您需要将FullRowSelect的{​​{1}}属性设置为ListView并处理true事件。将您想要拥有的逻辑放在函数的ItemActivate事件中，并将Click ItemActivate事件放在一个函数中。

<强> 实施例

在以下示例中，通过双击ListView的项目或选择和项目并单击ListView，消息框将显示所选项目的文本：
