When you create a .NET web form in Advanced Mode you may have issues with date format stored in the form data XML file.

To have the simple mode behavior, in form data dataset, all the datetime cols must have the following attributes:

- `DataType=System.DateTime`
- `DateTimeMode=Utc`

**.NET sample:**

```auto
System.Data.DataTable dt = new DataTable();  
System.Data.DataColumn myDateTimeField = new   
 DataColumn("field1",typeof(System.DateTime));  
 dt.Columns.Add(myDateTimeField);  
 myDateTimeField.DateTimeMode = System.Data.DataSetDateTime.Utc;

```
