Masked edit extender problem

Hi all

I am using latest version of ASP.NET Ajax in my C# web application. In my textbox, textmode is multiline. I am restricting the entry to textbox till 1000 chars.This works fine but supposingly if a user has entered few words and he/she wants to append to line, it overwrites it, doesn't allow append. How to fix this issue?
Here is my code:

Code:

<td valign="top">
                                    
                                    <asp:TextBox ID="txtProjects" runat="server" TextMode="MultiLine" CssClass="mtt" Width="40%" height="40px" />
                                   <cc1:FilteredTextBoxExtender ID="FilteredTextBoxExtender1" runat="server" TargetControlID="txtProjects" FilterMode="InvalidChars" InvalidChars="<>`~!@#$%^&*-_=+|{}[]"/>
                                    <cc1:MaskedEditExtender ID="MaskedEditExtender1" runat="server" Mask="?{1000}" TargetControlID="txtProjects" PromptCharacter="" />
                                    </td>
