Hi yin,
Thank you for contacting Syncfusion support.
Based on your provide details we have analysis the issue and we suspect that maybe you have missed to implement the INotifyPropertyChanged on your underline collection. “INotifyPropertyChanged” Which is helps to update the collection and property at runtime.
If you bound the complex property, the changes will not reflect in UI so we must to implement the NotificationObject to respective property to reflect the changes in view. For both implementation we have provided the codes in below code snippet please refer in it.
Please refer the sample, UG and code snippet,
Code snippet [C#]

public class OrderInfo : INotifyPropertyChanged
{
private int? orderID;
private CustomerInfo customersinfo;
//Complex Property
public event PropertyChangedEventHandler PropertyChanged;
private void RaisePropertyChanged(String Name)
{
if (PropertyChanged != null)
this.PropertyChanged(this, new PropertyChangedEventArgs(Name));
}
public int? OrderID
{
get { return orderID; }
set { this.orderID = value; RaisePropertyChanged("OrderID"); }
}
//Complex Property
public CustomerInfo CustomersInfo
{
get { return customersinfo; }
set
{
this.customersinfo = value;
RaisePropertyChanged("CustomersInfo");
this.CustomersInfo.PropertyChanged += CustomersInfo_PropertyChanged;
}
}
private void CustomersInfo_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
RaisePropertyChanged("CustomersInfo." + e.PropertyName);
}
public OrderInfo()
{
}
}
public class CustomerInfo : NotificationObject
{
private string firstName;
public string FirstName
{
get { return firstName; }
set
{
this.firstName = value;
RaisePropertyChanged("FirstName");
}
}
}
