JumpList GroupHeader format

[Oleg]

Hi,

i want to format group header in this way:

it is datetime, so regarding to http://www.telerik.com/community/forums/windows-phone/jumplist/groupformatstring-how.aspx#1655805

i've wrote 

public void GroupByDate(string s) {
    GenericGroupDescriptor<Program, DateTime> gd = new GenericGroupDescriptor<Program, DateTime>();

    gd.GroupFormatString = "{0:ddd MM MMM}";

    gd.KeySelector = (Program p) => {
        return p.StartTime.Date;
    };

    this.PlanningList.GroupDescriptors.Add(gd);
}

I need to set this date only in en-US locale. How can i implement it?

In case of normal datetime, i use this:

DateTime.Now.ToUniversalTime().ToString(format, new CultureInfo("en-US"))

Thank you!

Hi Oleg,

Thanks for writing and for your question.

The format strings are always in the context of the current culture on the phone. You cannot explicitly define the culture in the format string itself.

A possible way to implement this is to define a new property on your business object which is of type string, assign the already formatted group key to it and group by this property.

I hope this helps.
