hi ,
can i show in the calendar control (monthview) the week number , and if i click on the week that the whole days for this week are selected (like http://demos.devexpress.com/ASPxSchedulerDemos/Miscellaneous/DateNavigator.aspx(click on the right on the weeknumber)or like (http://demos.devexpress.com/ASPxSchedulerDemos/Miscellaneous/DateNavigator.aspx)so i can build queries on a week or week days
The NetAdvantage ASP.NET AJAX control that is comparable to what you want is our WebMonthCalendar.
I show a picture (attached) with the WebMonthCalendar, which lets you click its week numbers to select weeks (including Shift- and Ctrl- key multi-selection of non-contiguous weeks and date ranges).
A direct link to this sample,http://samples.infragistics.com/2010.1/WebFeatureBrowser/WebMonthCalendar/WebCalendar_MultiSelection.aspx
Cheers,
