HI,

You can do this by tracking the previous record in the viewmodel

Here is the binding for the XamDataGrid’s ActiveRecord property.

<igDP:XamDataGrid ExecutingCommand="xgrid1_ExecutingCommand" ActiveRecord="{Binding ActiveRecord, Mode=TwoWay}"
                          RecordActivated="xgrid1_RecordActivated"
                          Name="xgrid1" DataSource="{Binding People}">

Here is the property on the ViewModel:

Record activerecord;
public Record ActiveRecord
{
    get { return activerecord; }
    set {
        if (changeactive)
        {
            activerecord = value;
            prevrecord = activerecord;
            NotifyPropertyChanged("ActiveRecord");
        }
        else 
        {
            activerecord = prevrecord;
        // throw new Exception("cant change record");
        }
        
    }
          
}

Record prevrecord;
public Record PrevRecord
{
    get { return prevrecord; }
    set { prevrecord = value;
    NotifyPropertyChanged("PrevRecord");}
}

 When you run the sample, you can't change the XamDataGrid's ActiveRecord until you check the EnableActivation Checkbox.
