RadMaskedTextBox drops numbers when using browser back button

[Mark Perry]

When I load up the page and apply the appropriate mask to the textbox the data is displayed correctly.
If I then click another page and then use the browser's back button, the phone number is messed up and missing the last 4 digits while the other  6 are in random places within the mask?

<telerik:RadMaskedTextBox  ID="txtPhone" runat="server" Width="225px" MaxLength="10" DisplayMask="(###)###-####" Mask="##########" SelectionOnFocus="CaretToBeginning" />

The issue is in IE 8. We are using 2010.3.1317.35. The control is not wrapped in any AJAX.

Hello Mark,

There is indeed a problem with the RadMaskedTextBox control which I notified our developement team about. It seems the control persists the string from the display mask, instead of the value of the control. Our developers will investigate it further, confirm whether it is a bug and if so, fix it.

In the meantime, you could as a workaround use identical Mask and DisplayMask values, in this scenario there is no such problem.

Kind regards,
Tsvetina
