Protected Sub ChangedStatus(sender As Object, e As EventArgs)
If DirectCast(sender, DropDownList).SelectedItem.ToString = "ยื่นคำขอ" Then 'If selected ยื่นคำขอ --> Set ReqCalendarPopup1 not working
'Create object from usercontrol
Dim objTestControl As Controls_ctlCalendarSimple = DirectCast(Page.FindControl("Controls_ctlCalendarSimple"), Controls_ctlCalendarSimple)
'Create ReqCalendarPopup1 from object
Dim ReqCalendarPopup1 As RequiredFieldValidator = objTestControl.FindControl("ReqCalendarPopup1")
'Set ReqCalendarPopup1 to not working
ReqCalendarPopup1.Enabled = True
Else ' --> Set ReqCalendarPopup1 working
'Create object from usercontrol
Dim objTestControl As Controls_ctlCalendarSimple = DirectCast(Page.FindControl("Controls_ctlCalendarSimple"), Controls_ctlCalendarSimple)
'Create ReqCalendarPopup1 from object
Dim ReqCalendarPopup1 As RequiredFieldValidator = objTestControl.FindControl("ReqCalendarPopup1")
'Set ReqCalendarPopup1 to not working

b.ascx.Designer.vb
Code (VB.NET)
'Change Protected WithEvent to Public WithEvent (มีคำเตือนเล็กน้อยไม่ต้องสนใจ)
Public WithEvents ReqCalendarPopup1 As Global.System.Web.UI.WebControls.RequiredFieldValidator
a.aspx
Code (VB.NET)
Dim uctrl As Controls_ctlCalendarSimple = Me.FindControl("Controls_ctlCalendarSimple")
If uctrl isnot Nothing Then
uctrl.ReqCalendarPopup1.Sexybled = True
End If
ตรงนี้คือ Code หน้า user control ครับ ผมหาไฟล์ b.ascx.designer.vb ไม่เจอ ผมเลยสร้าง ฟังก์ชันด้านล่างให้ตัว ReqiuredFiealdValidator มันเป็น Public Code (b.ascx)
' Set property to ReqCalendarPopup1
Public WriteOnly Property ReqCtr() As Boolean
Set(ByVal value As Boolean)
ReqCalendarPopup1.Enabled = value
End Set
End Property
If DirectCast(sender, DropDownList).SelectedItem.ToString = "ยื่นคำขอ" Then
Dim uctrl As Controls_ctlCalendarSimple = Me.FindControl("Controls_ctlCalendarSimple")
uctrl.ReqCtr = False
Else
Dim uctrl As Controls_ctlCalendarSimple = Me.FindControl("Controls_ctlCalendarSimple")
uctrl.ReqCtr = True
End If
Protected Sub btnTest_Click(sender As Object, e As EventArgs) Handles btnTest.Click
Dim mc = Me.Master.FindControl("MainContent")
If mc IsNot Nothing Then
Dim uctrl = mc.FindControl("WebUserControl99")
If uctrl IsNot Nothing Then
Dim b As Button = uctrl.FindControl("btnSubmit")
If b IsNot Nothing Then
b.Enabled = False
b.Text = "Hello World"
End If
Dim rfv As RequiredFieldValidator = uctrl.FindControl("rfv99")
If rfv IsNot Nothing Then
rfv.Enabled = True
End If
Dim txtTest As TextBox = uctrl.FindControl("txtTest")
If txtTest IsNot Nothing Then
txtTest.Text = "Hello girl"
End If
End If
End If
End Sub
Protected Sub ChangedStatus(sender As Object, e As EventArgs)
If DirectCast(sender, DropDownList).SelectedItem.ToString = "ยื่นคำขอ" Then
Dim mc = Me.Master.FindControl("ContentPlaceHolder1")
If mc IsNot Nothing Then
Dim uctrl = mc.FindControl("dtpCOD")
If uctrl IsNot Nothing Then
Dim rfv As RequiredFieldValidator = uctrl.FindControl("ReqCalendarPopup1")
If rfv IsNot Nothing Then
rfv.Enabled = False
End If
End If
End If
Else
Dim mc = Me.Master.FindControl("ContentPlaceHolder1")
