Infinite Scrolling Image Gallery Design

Example MudBlazor Image Search page implementing a searchable grid gallery with MudTabs navigation and toggle actions; demonstrates MudGrid layout and basic infinite scroll.

## What's implemented - Top search bar (MudTextField) with adornment and avatar/app button group. - Primary navigation tabs via MudTabs/MudTabPanel. - Image gallery laid out with MudGrid and MudItem using MudImage cards. - Hover overlay with MudToggleIconButton actions for like/select. - Grouping of images by date labels (Today/Yesterday/Month Year). - Infinite scroll trigger with loading indicators (MudProgressCircular). ## Key components - MudContainer, MudPaper, MudTextField, MudTabs, MudTabPanel - MudGrid, MudItem, MudImage, MudText, MudDivider - MudToggleIconButton, MudIconButton, MudAvatar, MudProgressCircular - MudScrollToTop and local ImageViewModel class ## How it works - Two-way binding is used for UI state: @bind-Value on MudTextField for the search query and @bind-ActivePanelIndex on MudTabs for the active tab. - Image item state uses @bind-Toggled on MudToggleIconButton for IsLiked and IsSelected booleans on ImageViewModel. - Images are generated in GenerateImageData and stored in _allImages; GroupImages groups them by date string for display. - Infinite scroll is handled by OnScroll receiving ScrollEventArgs from MudScrollToTop and calling LoadImages when near the bottom. - Loading state toggles _isLoading and shows MudProgressCircular while fake network latency (Task.Delay) simulates retrieval. ## Styling - Uses MudBlazor components and utility classes (d-flex, pa-4, mx-*, typographic helpers). - Custom CSS in GoogleImageSearch.razor.css implements .image-gallery-container scrolling height, .image-card positioning, hover .image-overlay opacity transition, and overlay button styles. - Theme tokens appear (var(--mud-palette-lines-default), var(--mud-default-borderradius)). - Responsive grid behavior relies on MudGrid/MudItem breakpoints (xs, sm, md, lg) provided in the markup. ## Reuse steps 1. Add MudBlazor NuGet and call builder.Services.AddMudServices() in Program.cs; import MudBlazor namespace in _Imports.razor. 2. Include MudBlazor CSS and any theme setup in index.html/_Host.cshtml. 3. Copy the .razor and .razor.css files and the ImageViewModel class into the project. 4. Replace GenerateImageData with real API calls and map responses to ImageViewModel; remove Task.Delay used for demo. 5. Optionally add JS interop to compute accurate container clientHeight or use MudVirtualize for large lists. ## Limitations & next steps - Demo uses generated placeholder data and Task.Delay; no network/API wiring is included. - Scroll logic uses a fixed clientHeight value for the trigger; replace with JS interop or MudVirtualize for robust infinite scroll. - No persistence or server-side selection/like handling; state is local to the component. - Accessibility, keyboard navigation, image lazy-loading, and pagination controls are not implemented and should be added for production. - Authentication, rate limiting, and real image licensing checks are outside the sample scope.
