# Documentation: GroupImport Views

## 1. Purpose

This module provides the WPF view components for a Group Import wizard workflow. It contains three views—`GroupImportImportView`, `GroupImportOptionsView`, and `GroupImportPreviewView`—that implement interfaces from `DTS.Common.Interface.Groups` and handle user interaction for importing groups from files. The views serve as the UI layer, delegating business logic to `GroupImportViewModel` and validating user input before allowing progression through the wizard steps.

## 2. Public Interface

### GroupImportImportView

**Signature:** `public partial class GroupImportImportView : IGroupImportImportView`

| Member | Description |
|--------|-------------|
| `GroupImportImportView()` | Constructor. Calls `InitializeComponent()` to load the XAML-defined UI. |

---

### GroupImportOptionsView

**Signature:** `public partial class GroupImportOptionsView : IGroupImportOptionsView`

| Member | Description |
|--------|-------------|
| `GroupImportOptionsView()` | Constructor. Calls `InitializeComponent()` to load the XAML-defined UI. |
| `bool Validate(out List<string> errors, out List<string> warnings)` | Validates whether the user can proceed to the preview step. Returns `true` if at least one file is selected (`vm.SourceFiles.Length >= 1`); otherwise, adds `StringResources.Preview_NoFilesSelected` to errors and returns `false`. |

---

### GroupImportPreviewView

**Signature:** `public partial class GroupImportPreviewView : IGroupImportPreviewView`

| Member | Description |
|--------|-------------|
| `GroupImportPreviewView()` | Constructor. Calls `InitializeComponent()` to load the XAML-defined UI. |
| `void GroupName_Changed(object sender, TextChangedEventArgs e)` | Private event handler. Updates `group.GroupName` from the TextBox, calls `ch.GroupNameInvalidate()` on all channels, and invokes `vm.CheckGroupName()`. |
| `void GroupTags_Changed(object sender, TextChangedEventArgs e)` | Private event handler. Updates `group.GroupTags` from the TextBox. |
| `void IncludedChecked(object sender, RoutedEventArgs e)` | Private event handler. Calls `vm.InvalidateChannels()` when a group's included checkbox is checked. |
| `void IncludedUnchecked(object sender, RoutedEventArgs e)` | Private event handler. Calls `vm.InvalidateChannels()` when a group's included checkbox is unchecked. |
| `bool Validate(bool userIsAdmin, out List<string> errors, out List<string> warnings)` | Public validation method. Checks group and channel validity for import. Returns `true` if valid to proceed. See detailed behavior below
