Devxpress grid currency formatting - wpf

Question

I'm using Devxpress v13.1 and not allowed to upgrade it.
I am trying to render a devxpress grid from a dataset. I want $400.0000 to display as $400.00 and can't get it to work.
I have the following code:
public MainWindow{
DataSet TransactionList = GetDataFromXML();// Loads XML to DS
TransactionGrid.ItemsSource = TransactionList.Tables[0];
TransactionGrid.CustomColumnDisplayText += TransactionGrid_CustomColumnDisplayText;
}
void TransactionGrid_CustomColumnDisplayText(object sender, DevExpress.Xpf.Grid.CustomColumnDisplayTextEventArgs e)
{
if (e.Column.FieldName == "Amount1")
{
//e.Column.DisplayTemplate =
e.DisplayText = String.Format("{0:0.00}", e.Value);
}
}
xaml code:
<dxg:GridControl Name="TransactionGrid" HorizontalAlignment="Left" Height="Auto" Width="Auto" >
<dxg:GridControl.View >
<dxg:TableView AllowEditing="False"></dxg:TableView>
</dxg:GridControl.View>
<dxg:GridControl.Columns>
<dxg:GridColumn FieldName="Amount1" Header="Amount1" Width="80" >
</dxg:GridColumn>
</dxg:GridControl.Columns>
</dxg:GridControl
>

I used the TGrid_CustomColumnDisplayText event to achieve the results. Trying to implement StringFormat="c2" didnt work at the xaml level. I had to Call the statement below in the constructor of the xaml page.
TGrid.CustomColumnDisplayText += TGrid_CustomColumnDisplayText;
Event is as below-
void Tgrid_CustomColumnDisplayText(object sender,
DevExpress.Xpf.Grid.CustomColumnDisplayTextEventArgs e)
{
CultureInfo ciUsa = new CultureInfo("en-US");
if (e.Column.FieldName == "Amount")
{
e.DisplayText = String.IsNullOrEmpty(e.Value.ToString()) ? String.Empty : String.Format(ciUsa, "{0:c2}", Convert.ToDecimal(e.Value));
}
}
