I am using XAMDataGrid the source of which is bind to an observablecollection.

I have called the INotifyProperty changed event for "Value" property of class DataBlock in constructor as below:

this.CellData.PropertyChanged += (s, e) =>
{
if (e.PropertyName == nameof(Value))
this.OnPropertyChanged(nameof(Value));
};

I can see the field "value" is getting updated while debugging but I cannot see the updated value on XamDataGrid ,

the value on xamdatagrid is not getting changed while performing some operation. Only when I scroll up pr down I can sse the updated values.

Can you please suggest what is the issue in my code.

Below is my code:

The code behind code is :

public ObservableCollection<CalculationData> DataBlock
{
get
{
if (_DataBlock!= null)
return _DataBlock;

_AggregateDataBlocks = res;
return _AggregateDataBlocks;
}

private ObservableCollection<CalculationData> _DataBlock;}

public class CalculationData: INotifyPropertyChange
{

    public string name { get; private set; }

public object Value {
get {

        res = "abc";

        return res;
     }
   }

}

public event PropertyChangedEventHandler PropertyChanged;

private void OnPropertyChanged(string propName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propName));
}
}

and my XML code
