عدم اجرای رویداد Web User Control
سلام
وقت بخیر
من یک Web User Control ساختم که یک DropDownList داره و آیتم هاش توی Web Form اضافه می شه:
Screenshot 2024-12-11 111832.png
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
With Me.ProjectType
.Items.Clear()
.Items.Add(New ListItem("Windows Forms", "Windows Forms"))
.Items.Add(New ListItem("Console Application", "Console Application"))
.Items.Add(New ListItem("Workflow Console Application", "Workflow Console Application"))
.Items.Add(New ListItem("Asp.Net Web Application", "Asp.Net Web Application"))
.Items.Add(New ListItem("Asp.Net MVC Application", "Asp.Net Web Application"))
End With
End Sub
و یک رویداد سفارشی داره که همزمان با رویداد SelectedIndexChanged از DropDownList Raise می شه و در Web Form استفاده کردم ولی اجرا نمی شه....
Web User Controlo
Public Class DropDownField
Inherits System.Web.UI.UserControl
Public Event SelectedValueChanged(value As String)
Public Property FieldName() As String
Get
Return Me.Caption.Text
End Get
Set(ByVal value As String)
Me.Caption.Text = value
End Set
End Property
Public ReadOnly Property Items() As ListItemCollection
Get
Return Me.DropDownList1.Items
End Get
End Property
Private SelectedValueValue As String
Public Property SelectedValue() As String
Get
Return SelectedValueValue
End Get
Set(ByVal value As String)
SelectedValueValue = value
End Set
End Property
Public ReadOnly Property SelectedItem() As ListItem
Get
Return Me.DropDownList1.SelectedItem
End Get
End Property
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
Private Sub DropDownList1_SelectedIndexChanged(sender As Object, e As System.EventArgs) Handles DropDownList1.SelectedIndexChanged
Me.SelectedValue = Me.DropDownList1.SelectedItem.Value
RaiseEvent SelectedValueChanged(Me.DropDownList1.SelectedItem .Value)
End Sub
End Class
Web Form:
Private Sub ProjectType_SelectedValueChanged(value As String) Handles ProjectType.SelectedValueChanged
MsgBox(value)
End Sub
برای دریافت مقدار انتخاب شده باید از چه روشی استفاده کنم؟
