Avoid Save after validation fails.

Hi All,

I need to avoid the data saving once validation fails. I wrote a method in RowPersisting event. Validation message comes but data is going to save .So I need to return from the saving until validation sucess.

Here is my code.

protected void _(Events.RowPersisting<HMRCAPIConfigDetail> e)
        {
            HMRCAPIConfigDetail row = e.Row;
            if(row != null)
            {
                if(String.IsNullOrEmpty(row.Description))
                {
                    string msg = "Description Cannot be Empty";                    
                    WebDialogResult result = HMRCAPIConfigDetails.Ask(ActionsMessages.Warning, msg, MessageButtons.OK, MessageIcon.Warning, true);
                    return;
                }                
            }            
        }

Thanks
