VbCrLf in a multiline text field appears only when .Trim () is called

Question

I have an ASP TextBox with TextMode installed in MultiLine. I'm having trouble saving vbCrLf characters when the user tries to put lines in text. When the button on the page is clicked, I take the text from the control by trimming it with String.Trim and assigning the String property for the object to this value (which, in turn, assigns it to the private String internal variable of the object). Then the object takes the value from the private internal variable and issues it to the database by calling the stored procedure (the SP parameter in which it is placed is nvarchar (4000)).

ASPX page:

<asp:UpdatePanel ID="UpdatePanel2" runat="server" RenderMode="Inline" UpdateMode="Conditional"
                ChildrenAsTriggers="true">
  <ContentTemplate>
    <!-- some other controls and things -->
    <asp:TextBox TextMode="MultiLine" runat="server" ID="txtComments" Width="100%" Height="60px" CssClass="TDTextArea" Style="border: 0px;" MaxLength="2000" />
    <!-- some other controls and things -->
  </ContentTemplate>
</asp:UpdatePanel>

code behind:

ProjectRequest.StatusComments = txtComments.Text.Trim

object property:

Protected mStatusComments As String = String.Empty
Property StatusComments() As String
  Get
    Return mStatusComments.Trim
  End Get
  Set(ByVal Value As String)
    mStatusComments = Value
  End Set
End Property

saved proc call:

  Common.RunSP(mDBConnStr, "ProjectStatusUpdate", _
    Common.MP("@UID", SqlDbType.NVarChar, 40, mUID), _
    Common.MP("@ProjID", SqlDbType.VarChar, 40, mID), _
    Common.MP("@StatusID", SqlDbType.Int, 8, mStatusID), _
    Common.MP("@Comments", SqlDbType.NVarChar, 4000, mStatusComments), _
    Common.MP("@PCTComp", SqlDbType.Int, 4, 0), _
    Common.MP("@Type", Common.TDSqlDbType.TinyInt, 1, EntryType))
