Hi Daniel,
I assume you are using DatePicker control. In order to get the selected date, you have to use the Date property. Here are all properties described for the DatPicker Selection https://docs.telerik.com/devtools/maui/controls/datepicker/datepicker-selection The property is bindable property.

Here is a sample code:
<telerikInput:RadDatePicker Date="{Binding Date, Mode=TwoWay}"/>
ViewModel:
public class ViewModel : INotifyPropertyChanged
{
private DateTime? date;
public ViewModel()
{
this.Date = DateTime.Now;
}
public DateTime? Date
{
get
{
return date;
}
set
{
if (date != value)
{
date = value;
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("Date"));
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
}
General Data Binding information:
More details about data bindings can be found in the official .NET MAUI documentation: https://docs.microsoft.com/en-us/dotnet/maui/xaml/fundamentals/data-binding-basics
I suggest you review all articles inside the Fundamentals section of the .NET MAUI documentation.
