Set Selected Tab From ViewModel | Infragistics Forums

Thanks again for the quick response. Allow me to briefly describe what I'm trying to do. I have a tabgrouppane in a user control with 6 tabs(let's call this my wizard control). A user entering the app goes to the first tab and enters data (companyname and companydesc) and then clicks "Next". If the validation for the fields passes, the tab to the right of the current active tab should become focused. I have a validator class for each tab because each tab corresponds to a separate viewmodel. Each viewmodel has an instance of its validator and vice versa. The validator also has access to the wizard control via a wizardviewmodel. I am able to set the ActiveTab property form the validator below, but that change isn't reflected in the tabgrouppane. Here is the validator code:

    public class CompanyValidator
    {
        private CompanyViewModel companyViewModel { get; set; }
        private WizardViewModel wizardViewModel { get; set; }

        public CompanyValidator(CompanyViewModel cvm)
        {
            this.companyViewModel = cvm;
        }

        #region Public Methods

        public void Validate()
        {
            ObservableCollection<ValidationFailure> localValidationErrors =
                new ObservableCollection<ValidationFailure>();

            #region Validate Company

            if (companyViewModel.Name == String.Empty)
            {
                localValidationErrors.Add(new ValidationFailure("CompanyName",
                    Properties.Resources.EmptyCompanyNameString));
            }

            if (companyViewModel.Description == String.Empty)
            {
                localValidationErrors.Add(new ValidationFailure("CompanyDesc",
                    Properties.Resources.EmptyCompanyDescString));
            }

            #endregion

            companyViewModel.ValidationErrors = localValidationErrors;

            if (localValidationErrors.Count > 0)
            {
                StringBuilder sb = new StringBuilder();
                foreach (var error in localValidationErrors)
                {
                    sb.AppendLine(error.Description);
                }

                MessageBox.Show(sb.ToString());
            }
            else
            {
                // Save the company.
                companyViewModel.Save();
                wizardViewModel.SetActiveTab(1); // Hard-coded to the next tab for a test.
            }
        }
