How to disable mask for MaskedTextBox

[Konrad]

Hi, i use RadMaskedTextBox in my aspx:

<telerik:RadMaskedTextBox ID="edtNumber" runat="server" CssClass="EditBox" Width="300px"

    Mask="## #### #### #### #### #### ####"
 EnableEmbeddedSkins="false"></telerik:RadMaskedTextBox>

But for some conditions I want to disable mask in codebehind. Is any way to do this, because this doesn't work:

edtNumber.Mask = null;
edtNumber.Mask = string.Empty;

Hello Konrad,

Try setting DisplayMask as shown below.
C#:

if(condition)
{
    edtNumber.DisplayMask=" ";
}

Thanks,
Shinu.

Mask is invisible to the moment when I click the input. I would like to disable mask completely.

Edited:
Nevermind, I have used second textbox ... -.-
