Hi all,
I'm writing a custom textblock control thats populate hyperlinks and raises event when clicked to hyperlink.
I wrote this code but I got stucked.
My code is :
Imports System.Text.RegularExpressions
Public Class CustomTextBlock
Inherits TextBlock
Public Event Klik As EventHandler(Of EventArgs)
Public ReadOnly InlineCollectionProperty As DependencyProperty = DependencyProperty.Register("InlineCollection", GetType(String), GetType(CustomTextBlock), New PropertyMetadata(New PropertyChangedCallback(AddressOf CustomTextBlock.InlineChanged)))
Private Shared Sub InlineChanged(ByVal sender As DependencyObject, ByVal e As DependencyPropertyChangedEventArgs)
DirectCast(sender, CustomTextBlock).Inlines.Clear()
Dim kelimeler = Split(e.NewValue, " ")
For i = 0 To kelimeler.Length - 1
If Regex.Match(kelimeler(i), "(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?").Success Then
Dim x = New Hyperlink(New Run(kelimeler(i)))
x.AddHandler(Hyperlink.ClickEvent, New RoutedEventHandler(AddressOf t_Click))
x.ToolTip = kelimeler(i)
x.Tag = kelimeler(i)
DirectCast(sender, CustomTextBlock).Inlines.Add(x)
If Not i = kelimeler.Length Then DirectCast(sender, CustomTextBlock).Inlines.Add(" ")
Else
DirectCast(sender, CustomTextBlock).Inlines.Add(kelimeler(i))
If Not i = kelimeler.Length Then DirectCast(sender, CustomTextBlock).Inlines.Add(" ")
End If
''//Console.WriteLine(kelime(i).ToString.StartsWith("@"))
Next
kelimeler = Nothing
End Sub
Public Property InlineCollection As String
Get
Return DirectCast(GetValue(InlineCollectionProperty), String)
End Get
Set(ByVal value As String)
SetValue(InlineCollectionProperty, value)
End Set
End Property
Private Shared Sub t_Click(ByVal sender As Hyperlink, ByVal e As System.Windows.RoutedEventArgs)
e.Handled = True
RaiseEvent Klik(sender, EventArgs.Empty)
End Sub
End Class
This code gives error at RaiseEvent Klik(sender, EventArgs.Empty)
Error is : Cannot refer to an instance member of a class from within a shared method or shared member initializer without an expliticit instance of the class.
Thanks for your answers,
Alper
