C#

protected virtual Task<bool> OnUpdateAsync(
	IRGDataContext context,
	TEntity dataRec,
	RGClientParam param,
	RGUIMessages messages
)

Parameters

context IRGDataContext: The context.
dataRec TEntity: The data record.

Example

C#

protected override async Task<bool> OnUpdateRecAsync(RecroTrack tracking, Person dataRec, RGClientParam arg, RGUIMessages messages)
{
    if (arg.IsNewEntity)
    {
        //New data entry with custom modifications
    }
    else
    {
        //Modify data entry with custom modifications
    }

    //Invoke IRecroGridUpdate
    if (!await base.OnUpdateRecAsync(tracking, dataRec, arg, messages))
    {
        return false;
    }

    if (string.IsNullOrEmpty(dataRec.FirstName))
    {
        //Error message associated with a field from the RecroDict dictionary
        messages.AddError(RecroDict.Get(RecroGridContext.HttpContext, "Person.Validation", "FirstName"), Alias2ClientName("FirstName"));
    }
    if (!ExternalValidation(dataRec))
    {
        messages.AddError("Custom error message!");
    }
    return messages.ErrorCount == 0;
}
