When using MaskedEditExtender Masktype time, how to override unwanted behavior?

The following two lines work fine if the input is correctly specified:

<asp:TextBox ID="MondayOpenTextBox" runat="server" MaxLength="5" /> <Ajax:MaskedEditExtender ID="MondayOpenMaskedEditExtender" runat="server" TargetControlID="MondayOpenTextBox" AcceptAMPM="false" MaskType="Time" Mask="99:99" />

If the user enters "12" and then moves on to the next field, the minutes are filled with the current minute. This is not desirable for this page. I would like to either display an error message or fill in "00" for the missing numbers.

It does not help:

 <asp:RegularExpressionValidator runat="server" ID="ValidateMondayOpenTextBox" ControlToValidate="MondayOpenTextBox" Display="Dynamic" ErrorMessage="X" ValidationExpression="\d\d:\d\d" />

since the field is apparently formatted by the time the validator gets its turn on it.

You can set the AutoComplete property of your MaskedEdit extender to false to prevent it from filling out empty masked characters with the current time:

 <Ajax:MaskedEditExtender ID="MondayOpenMaskedEditExtender" runat="server" TargetControlID="MondayOpenTextBox" AcceptAMPM="false" MaskType="Time" Mask="99:99" AutoComplete="False" />

Therefore, your validator should be able to do its job correctly.

To fill it: 00, you can set the AutoCompleteValue property to "99:00"
