Question

I don’t find a CanGrow property on the Textbox control. This is common in some other controls, and what it does is expand the control to acomodate more data. Anyway to get this feature in the TextBox?

Answer 1

Well, I came up with this:

Private Sub TextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox.TextChanged
        'check to see if textbox has text
        If (TextBox.TextLength > 0) Then
            'resize height of textbox by count of lines (plus add some padding)
            TextBox.ClientSize = New Size(TextBox.ClientSize.Width, Convert.ToInt32((TextBox.Lines.Length * TextBox.Font.Height) + (TextBox.Font.Height * 0.5)))
        Else
            'resize to one line height (plus padding)
            TextBox.ClientSize = New Size(TextBox.ClientSize.Width, Convert.ToInt32(TextBox.Font.Height + (TextBox.Font.Height * 0.5)))
        End If
End Sub

Note: it doesn’t work with word-warp.
