用户标签或单击其他文本框时检查输入 [英] Check input when user tab or click other textbox

问题描述

大家好，

当用户按下Tab键或单击其他文本框时，我想用来检查文本框的事件是什么?我已经有了代码，但是我不知道事件.它只是在用户想要创建新帐户时检查确认密码.有人可以告诉我吗?

Hi all,

What is the events for textbox which I want to use to check when user press Tab key or click other textbox? I already have the code, but I don''t know the events. It just check the confirmation password when user want to create new account..Could someone tell me?

推荐答案

您可以在文本框中使用onblur事件，这基本上意味着焦点从控件中移出

you can use the onblur event in a textbox which basically means that the focus is moved from the control

尝试针对失焦事件使用以下代码

try following code for lost focus event

Private Sub TextBox1_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBox1.Validating
    Dim est As Decimal
    If TextBox1.Text.Length = 0 then Exit Sub   '' optional
    If Not Decimal.TryParse(TextBox1.Text.Trim, est) Then
        e.Cancel = True
        TextBox1.SelectAll()
    Else
        TextBox1.Text = est.ToString("N0")
    End If
End Sub
