Timecode Mask
posted

Hi Infragistics,


We have a need for an editable video timecode field in an application. We'd like to xamMaskedInput (v2014) but have hit a problem with some (optional) special characters.

 

The basic timecode is this...

 

HH:MM:SS:FF

 

Where...

 

HH = 00 - 99

MM = 00 - 59

SS = 00 - 59

FF = 00 - 24

 

And this mask works ok (with a PromptChar of "")...

 

{number:0-99}:{number:0-59}:{number:0-59}:{number:0-24}

 

But we would like some optional characters at the beginning and end, which the user will enter in certain situations. At the beginning we would like either a "+" or "-" and at the end a "*"

 

So...

 

[+ or -]HH:MM:SS:FF[*]

 

I've managed to add the "*" with the following mask at the end...

 

{char:1:*}

 

But I've tried to get "+" and "-" working and just can't seem to find a way using the standard masks...

 

http://es.infragistics.com/help/wpf/xaminputs_masks.html

 

The "-" and "+" masks already defined, don’t work for this situation.


Is it also possible to have the ":" literals in the above example only appear when the cursor has reached the correct position?


Using a PromptChar of "" the initial edit text looks like this...


::::


Which is not ideal. We've tried using a PromptChar of "0" but then the "*" mask looks odd.


It sounds like this is too custom for xamMaskedInput  and maybe we need a masked control using Regex support?


Any help would be much appreciated.

    Hello,

     

    Thank you for your post. I have been looking into it and it seems like that it is better to use regular expression than Mask in order to achieve the functionality you want. You can set a regular expression like this:

    <ig:XamMaskedInput  >
        <ig:XamMaskedInput.ValueConstraint>
            <ig:ValueConstraint RegexPattern="your regEx pattern"/>
        </ig:XamMaskedInput.ValueConstraint>
    </ig:XamMaskedInput>

     

    Please let me know if you have further questions on this matter.

     

    Looking forward for your reply.
