DatePicker with texts files

Question

Hi  

I am using date picker in my app for users to navigate back and forth to any content of the day they missed for them to catch up on it I have 365 text files in my folder for each day. The challenge am having is how to bind each 365 text files to each day of the year   Here is my code below  

xaml

<toolkit:datepicker x:name="pickerdt" margin="0,10,0,0" header="Select date" verticalalignment="Top" valuechanged="pickerdt_ValueChanged" xmlns:x="#unknown" xmlns:toolkit="#unknown" />  

xaml.cs

private void pickerdt_ValueChanged(object sender, DateTimeValueChangedEventArgs e) { var dayvalue = pickerdt.Value.Value.Day; }  

Kindly help
