DataGrid LoadingRow with DataGridRowEventArgs

I've got a problem with the DataPager when I used LoadingRow.

        public void LoadFund(Object sender, DataGridRowEventArgs e)
        {
            MyBalance prod = e.Row.DataContext as MyBalance;
            prod.Balance = 90;
        }

If I use this DataGridRowEventArgs my DataPager won't work anymore. Why Please?

Hi! In xaml odes are follows;

<Grid x:Name="LayoutRoot" Background="White">

                <TextBox Text="{Binding Path=SelectedRecord.Purpose, Mode=TwoWay}"></TextBox>
                <TextBox x:Name="MyText"></TextBox>
            </StackPanel>
        </ScrollViewer>

    </Grid>

while on xaml.cs codes are as follows;
        public void LoadFund(Object sender, DataGridRowEventArgs e)
        {
            MyBalance prod = e.Row.DataContext as MyBalance;
            if (prod.A_In > 0)
            {
                e.Row.Background = new SolidColorBrush(Color.FromArgb(255, 100, 100, 100));
                prod.Balance = 90;
            }
            else
            {
                e.Row.Background = new SolidColorBrush(Color.FromArgb(255, 200, 200, 200));
            }
        }

at the time that i use "prod.Balance = 90;" the pager will not work, but if I will not use that everything is working...
Meir RivkinFull stack Software EngineerCommented:
so the only problem is with this line:   prod.Balance = 90; ???
try this:
comment the following line in your xaml:
    <sdk:DataGridTextColumn Binding="{Binding Balance, StringFormat=#\,##0.00}" Header="Balance" Foreground="Blue" Width="75"/>

now run your app with prod.Balance = 90;
does the pager works now>?

public void LoadFund(Object sender, DataGridRowEventArgs e)
        {
            MyBalance prod = e.Row.DataContext as MyBalance;
            prod.Balance = 90;
            BalanceGrid.DataContext = prod;
        }

Is the setter on prod.Balance throwing an exception?
