关于SelectAll的问题 [英] Question on SelectAll

问题描述

在几个文本框的GotFocus事件中，我包含了诸如

" txtMyTxtBox.SelectAll"之类的代码。当我从文本框切换到文本框时，获得焦点的

文本框中的文本被按预期选中但如果我使用鼠标来点击文本框，则文本不是选择。我怀疑这有什么东西

与各种事件发生的命令有关？在VB6中这很有用。


有没有人对这里发生的事情有任何建议和/或

当鼠标用于鼠标时获取文本的方法改变焦点？


Wayne

In the GotFocus event for several text boxes I include code such as
"txtMyTxtBox.SelectAll". When I tab from textbox to textbox the text in the
textbox that got focus is selected as expected but if I use the mouse to
click on the textbox the text is not selected. I suspect this has something
to do with the order in which the various events fire? In VB6 this worked.

Does anyone have any suggestions regarding what is happening here and/or
ways to get the text selected when a mouse is used for changing focus?

推荐答案

你应该使用''enter''事件 - 而不是gotfocus活动

我甚至都不知道。让我试试你的建议。 BTW，是LostFocus

离开物体时仍然是最好用的（我想重置背景

颜色）

我试过使用你建议的输入事件（我确实看到有一个

对应的Leave事件）但是虽然事件触发并且文本框的背景颜色发生了变化，它仍然没有选择文本。在下面的代码

中，SetBackground子只是更改文本框的背景颜色 -

，以帮助用户查看哪些对象具有焦点。如果我浏览代码我可以

看到SelectAll正在执行但是文本没有结束

被选中 - 我会做一些挖掘输入事件。


Private Sub txtAssocContactLastName_Enter（ByVal sender As Object，ByVal e As

System.EventArgs）处理txtAssocContactLastName.Enter


SetBackground（）


txtAssocContactLastName.SelectAll（）


结束子

Hal;

I tried using the enter event as you suggested (and I do see that there is a
corresponding Leave event) but although the event fires and the background
color of the textbox changes, it still does not select the text. In the code
below, the SetBackground sub simply changes the textbox''s background color -
to help the user see what object has focus. If I walk through the code I can
see that the SelectAll is being executed but the text does not end up
selected - I''ll do some digging about the enter event.

Private Sub txtAssocContactLastName_Enter(ByVal sender As Object, ByVal e As
System.EventArgs) Handles txtAssocContactLastName.Enter

SetBackground()

txtAssocContactLastName.SelectAll()

End Sub
