Hi All,

I am creating my custom control. In file mycustomcontrol.vb:

Partial Public Class MyCustomControl
Inherits Control
...
Public ReadOnly TitleProperty As DependencyProperty = DependencyProperty.Register("Title", GetType(String()), GetType(MyCustomControl()), Nothing)

Public Property Title() As String
Get
Return CType(GetValue(TitleProperty), String)
End Get
Set(ByVal value As String)
SetValue(TitleProperty, value)
End Set
End Property

What do you have in line 22 of Page.xaml?

Hi Jim,

sorry, I didn't tell, line 22 of page.xaml doesn't exist! It has only 16 lines. The one I posted is line 14:

 <dr:CustomEntryControl Title="blah"></dr:CustomEntryControl> 

it doesn't matter whatever I set the property, the error keeps showing. I guess it has something to do with my VB code, since Karen Corby's example works smooth (it is C#). But I cannot realize what, since the help doesn't help and the error cannot be found in Google. Quite strange.

Below is a screenshot:

Hi Dario,

I'm not very familiar with VB.Net. But I think the problem is with the way you have defined your DependencyProperty. Try changing it to this:

Public ReadOnly TitleProperty As DependencyProperty = DependencyProperty.Register("Title", GetType(String), GetType(MyCustomControl), Nothing)

Basically just remove the brackets that follow String and MyCustomControl.

hi ,

you might miss events which are declared in xaml but not in xaml.vb ,

or u might have a property which is not defined in your project or as in xaml control properties.

I think the problem is with dr content ..make sure you add correct namespace of  dr in your present xaml page..

Hi Jim, hi Hari,

thank you very much both for your help. This is the syntax I finally used:

Public ReadOnly TitleProperty As DependencyProperty = DependencyProperty.Register("Title", GetType(String), GetType(CustomEntryControl), Nothing)

Public Property Title() As String
Get
Return CType(GetValue(TitleProperty), String)
End Get
Set(ByVal value As String)
SetValue(TitleProperty, value)
End Set
End Property

Unfortunately the problem persisted, so I started randomly delving in the rest of the code in the hunt of the culprit, and surprise! Now it magically disappeared, and I cannot recall what did fix it! I someone encounters the same issue please let me know and I can send the entire code. I wish you a good day!

Best regards,
Dario Rossa

The age parse error cames up when u are not declaring an event in the code behind and it is in the xaml part... as i can see u have no declared event... try to remove de

XMLS:dr="" in your Usercontrol header... and the CustomEntrycontrol to checkout if that's the problem... if it is... then this event is missing in Entrycontrol.xaml...

Age parse error does not tell u that the error is in a clr u are calling but in the line where it is loaded...

Hope it help...
