Hi Andreas,

We don't have a setting exposed for the MaskedTextBox.PromptIndicatorType, but you can use a custom Style to set it. This should work:

xmlns:editors="http://schemas.actiprosoftware.com/winfx/xaml/editors"
xmlns:themes="http://schemas.actiprosoftware.com/winfx/xaml/themes"

<Style x:Key="{x:Static themes:EditorsCommonDictionary.MaskedTextBoxInlineStyleKey}" TargetType="editors:MaskedTextBox"
        BasedOn="{StaticResource {x:Static themes:EditorsCommonDictionary.MaskedTextBoxInlineStyleKey}}">
    <Setter Property="PromptIndicatorType" Value="Character" />
</Style>

You can set the PromptChar also, but it defaults to the underscorce character. You can also set the PromptBrush here, which is used to render the character or geometry.

Thanks very much. That's exactly what I wanted.

Hi,

With the above style, how would I specify the mask to display 2 characters for the hours and minutes for time display? No matter what mask I specify, it always only prompts for one character for the hour part.
eg ##:## # for hours, minutes and AM/PM

Thanks
Andreas

Hi Andreas,

Only 1 prompt is display because currently the user can enter 1 or 2 digits (since 1-9 are all valid hours). The DateTimeHourPart has a Mask property that you could change to "\d{2}", but you'd have to explicitly change it (i.e. it can't be changed using an implicit Style). You could probably do this via an attached behavior, which uses an inherited attached property that looks for DateTimeHourPart/DateTimeMinutePart types.

The problem is the user would still be able to enter a single digit, as the parts just use the MaskedTextBox to ensure only valid digits are entered and doesn't verify the "length" of the text.
