What I did was created a new getter in the original object

In the CellExitedEditmode I am refreshing the datagrid

Do you think there would be any performance issues using either approach?

Hi, 

If your properties are generated, then that approach won't work. 

You could just listen to the CellExitedEdit mode event then, and update the 2nd field your self via the Row data property off of the cell. 

YourData data = e.Cell.Row.Data;

data.otherProperty = newCalculatedValue;

I created a partial class and am adding code with the same field name as gerenated by metadata.cs

public decimal Field1
        {
            set
            {
               
                if (this._field1 != 0)
                {
                    this._field1 = System.Convert.ToDouble(value);

                    this.OnPropertyChanged("Field1");
                    this.OnPropertyChanged("Field2");
                }
            }
        }

But i get error that the 'xxx.web.classname' already contains definition for property Field1

I am a newbie

Can you explain where will this code reside

Hi, 

Then you can simply raise the PropertyChanged event for your other property. 

For example: 

Prop1 and Prop2. 

When i change Prop1, i want Prop2 to be updated as well, so in the Setter of Prop1

public obj Prop1
{
         set
         {
                if(this._prop1 != value)
                {

                    this._prop1 = value;
                    this.OnPropertyChanged("Prop1");
                    this.OnPropertyChanged("Prop2");

                }
         }
}
