query-string-bindable

Blazor filters become bookmarkable by synchronizing filter model state with the URL query string via NavigationManager binding. This two-way mapping ensures search, pagination, and sort settings persist across navigation and reloads so views can be shared.

INotifyPropertyChanged integration detects filter model property changes and triggers reactive UI updates. When URL query parameters update the bound filter model, the property change notification automatically reloads the data grid with the new filtered results.

Applying debounce to text input filters prevents excessive API calls during URL query string binding. Debounce delays the API request and query parameter mapping until typing pauses, ensuring the data grid only reloads once the user finishes entering search criteria.

Blazor filter state maps directly to API query parameters for server-side paging, filtering, and sorting. The filter model properties translate into API-compatible query parameters, enabling the backend to process search, pagination, and status criteria efficiently.

Query string binding works for Blazor control panels by supporting multiple filter types simultaneously. Search text, pagination numbers, sorting columns, and status selections all map to distinct URL query parameters, restoring full panel state on navigation.

Filters reset because the filter state lacks URL query string synchronization. Without binding the filter model to the NavigationManager, Blazor cannot restore search, pagination, or sort settings from the URL during back, forward, or reload navigation scenarios.
