在这里，看看在此：在ASP.NET中创建用户控件 [ ^ ]

Here, have a look at this: Creating User Controls in ASP.NET[^]

步骤1： - 在您的usercontrol中将此文件用于触发的textchange事件

Step1:-do this in your your usercontrol for fired textchange event

'declare the delegate
Public Delegate Sub TextChangedHandler(ByVal sender As Object, ByVal e As System.EventArgs)
    
    'Public Event TxtChang As TextChangedHandler
    Public Event TxtChanged As TextChangedHandler
 Protected Sub TextDatepicker_TextChanged(sender As Object, e As EventArgs) Handles TextDatepicker.TextChanged
        ' RaiseEvent TxtChang(sender, e)
        RaiseEvent TxtChanged(sender, e)

step2： - 这是在您的代码页上

step2:- do this is on your code page

 Public Sub dtJSCalendarControlLoc_TxtChanged(sender As Object, e As EventArgs) Handles dtJSCalendarControlShift.TxtChanged
        Try
           ' btn_showCal(sender, e)
'put here your method or logic code
        Catch ex As Exception

        End Try

    End Sub
