Try changing the declaration to this:
[highlight=vb]Private WithEvents comp As DigitalRune.Windows.TextEditor.TextEditorControl[/highlight]
And in Form1's load event, initialize the comp:
[highlight=vb]comp = Me.TabControl1.SelectedTab.Controls(0)[/highlight]
If the above line doesn't works, try casting:
[highlight=vb]Dim TxtEd As DigitalRune.Windows.TextEditor.TextEditorControl = Me.TabControl1.SelectedTab.Controls(0)[/highlight]
[highlight=vb]Private WithEvents comp As DigitalRune.Windows.TextEditor.TextEditorControl[/highlight]
And in Form1's load event, initialize the comp:
[highlight=vb]comp = Me.TabControl1.SelectedTab.Controls(0)[/highlight]
If the above line doesn't works, try casting:
[highlight=vb]Dim TxtEd As DigitalRune.Windows.TextEditor.TextEditorControl = Me.TabControl1.SelectedTab.Controls(0)[/highlight]
Initializing in the load event, well thank you master <3
No Prob ^^
Just to let you know why it didn't work is because the nested/child control did not exist when the comp object was initialized so the *********enceException was thrown.
