Xamarin ValueMember for UIPickerView?
When working with combo boxes for windows forms application, you can have a DisplayMember (which is what is shown) and a ValueMember (which is the value that the user doesn't see but the code uses for other processes)
I was wondering if there is a similar sort of function for UIPickerViews in Xamarin

yeah, I did it a different way though by having different public variables in the view model and by using a list as well

Yes! you can implement it in UIPickerView.
string DisplayMembers = new string "January", "February", "March",...,"December" ;
int ValueMembers = new int 1,2,3,...,12 ;
And in the method of Delegate
public override nint GetRowsInComponent(UIPickerView pickerView, nint component)
return DisplayMembers.Length;
public override string GetTitle(UIPickerView pickerView, nint row, nint component)
if (component == 0)
return DisplayMembers[row];
else
return row.ToString();
public override void Selected(UIPickerView pickerView, nint row, nint component)
//...
var valueMember=ValueMembers[row].ToString();
// do something you want about valueMember
