How to save the Grid State in a WASM project? How to save the Grid State in a WebAssembly through a controller? How to save the Grid State in a WebAssembly from the browser's LocalStorage?

## Solution

The [sample app in GitHub](https://github.com/telerik/blazor-ui/tree/master/grid/save-state-in-wasm-through-controller) shows two ways to store the `GridState`:

* Through a custom controller;
* Through a custom service that calls the browser's `LocalStorage`.
