What do you mean by fill? Are you not able to assign values to this masked control as user input / programmatically?

MaskedTextBox is essentially an extender that attaches to a TextBox control to restrict the kind of text that can be entered. If you are referring to a AJAXControlToolkit MaskEditExtender control, then you have to set the TargetControlID pointing to the actual TextBox that you want to apply the mask. For example:

C#

<cc1:MaskedEditExtender ID="MaskedEditExtender1" runat="server" TargetControlID="TextBox1" .../>

You can then use the .Text property of TextBox1 to get the actual value being masked.

C#

string theValue = TextBox1.Text;
