为什么我必须在按钮上单击两次 [英] Why do I have to click twice on the button

问题描述

我添加了两个DateTimePicker表单（从/到）。一键。一个标签。单击按钮时，Datagridview会过滤。但您必须单击两次才能显示标签中的总数。我问谷歌翻译。 :)



我尝试了什么：



我试过按钮点击事件。但它没有。

解决方案

通常情况下，Button没有DoubleClick事件。

但是对自定义按钮进行了一些更改这是可能的。

看看这个：

I've added two DateTimePicker form (from / to). One button. One label. Datagridview filters when I click on the Buttons. But you have to click twice to show the total in the label. I'm asking with Google translation. :)

What I have tried:

I tried button click event. But it did not.

解决方案

Normally a Button doesn't have a DoubleClick-Event.
But with some changes to a customized Button it is possible.
