thanks lot, btw i'm beginning programmer, don't have lot of experience, have nice idea , want work out properly, please go easy on me.

you should set both displaydate="{binding registerdate}" , selecteddate="{binding registerdate}".

try :

xaml code :

<calendar x:name="mycalender" displaydate="{binding registerdate}" selecteddate="{binding registerdate}" /> <textbox x:name="txtvisitorid" /> <button name="btnbinddate" click="btnbinddate_onclick" content="setcurrentdate"/> 

cs code :

private void binddata(int visitorid) {     using (var context = samplecontext.getcontext())     {         var visitor = context.visitors.firstordefault(x => x.visitorid == visitorid);         mycalender.datacontext = visitor;     } }  private void btnbinddate_onclick(object sender, routedeventargs e) {     var id = int.parse(txtvisitorid.text);     binddata(id); } 

visitor class :

public class visitor {     [key]     public int visitorid { get; set; }     public string name { get; set; }     public datetime registerdate { get; set; } }
