winforms - Need to have a grid Grouped into logical groups based on date -


i'm dealing situation need group devexpress grid on basis of date column. issue is, need groups called: past, current, , future. here linq:

gridjobsummary.datasource = luke in dbcontext.jobbookings             luke.locumid == locumid             orderby luke.job.jobdate descending             select new {                 luke.jobid,                 luke.job.jobdate,                 clientid = luke.job.branch.clientid,                 clientname = string.format("{0} ({1})", luke.job.branch.client.name, luke.job.branch.client.number),                 branchid = luke.job.branchid,                 branchname = string.format("{0} ({1})", luke.job.branch.number, luke.job.branch.number),                 jobbookingstatusname = luke.jobbookingstatus.name             };  gridjobsummaryview.columns["jobid"].visible = false; gridjobsummaryview.columns["clientid"].visible = false; gridjobsummaryview.columns["branchid"].visible = false;  gridjobsummaryview.columns["jobdate"].displayformat.formattype = formattype.datetime; gridjobsummaryview.columns["jobdate"].displayformat.formatstring = "ddd, dd-mmm-yyyy"; gridjobsummaryview.columns["jobdate"].sortorder = columnsortorder.ascending;

now,

if [job date < today], goes past group.

if [job date >= today and <= (today + 1 month)], it's current.

if [job date > (today + 1 month)], it's future.

how can have grid grouped virtual group? regards.

add property "groupname" selected objects:

select new {                 luke.jobid,                 luke.job.jobdate,                 clientid = luke.job.branch.clientid,                 clientname = string.format("{0} ({1})", luke.job.branch.client.name, luke.job.branch.client.number),                 branchid = luke.job.branchid,                 branchname = string.format("{0} ({1})", luke.job.branch.number, luke.job.branch.number),                 jobbookingstatusname = luke.jobbookingstatus.name,                 groupname = getgroupnamebydate(luke.job.jobdate)             };  // ..... string getgroupnamebydate(datetime date) {     var today = datetime.today;     if ( date < today ) { return "past"; }     else if ( date >= today && date <= today.addmonths( 1 ) ) { return "current"; }     else { return "future"; } }
