Hi,

You can simply load the CountryDto, then add new row to the StateProvince table. Here's an example:

CountryDto.StateProvinceRow spRow = (from reg in CountryDto.StateProvince
where reg.RowState != DataRowState.Deleted && 
String.Compare(reg.Name, name, StringComparison.CurrentCultureIgnoreCase) == 0
select reg).FirstOrDefault();
if (spRow == null)
{
spRow = CountryDto.StateProvince.NewStateProvinceRow();
spRow.CountryId = CountryId;
}

spRow.Name = name;
spRow.Ordering = Int32.Parse(e.Item[_GridOrderingString].ToString());
spRow.Visible = Boolean.Parse(e.Item[_GridVisibleString].ToString());

if (spRow.RowState == DataRowState.Detached)
CountryDto.StateProvince.Rows.Add(spRow);

CountryManager.Save(CountryDto);

Hi,

thank you for reply.

It helped partially. Although I used the code above, I had to update country Id for all existed stated and the next code was used before saving:

countryDto.EnforceConstraints = false;

if (countryDto.HasChanges())

{

if (countryDto.Country.Rows.Count > 0)

{

var countryId = countryDto.Country[0].CountryId;

foreach (CountryDto.StateProvinceRowstateProvinceRow1in countryDto.StateProvince.Rows)

{

stateProvinceRow1.CountryId = countryId;

}

}

}

countryDto.EnforceConstraints = true;
