Grid Filter Memory

[junwoolee00]

Make a way to make ti so pages remember the grid filtering applied

[junwoolee00]

Made it store current filters applied on local storage and then apply it to the grid upon loading page

Need to refactor code, try to minimize the amount needed to put into the page and make a component maybe for it

Formatted the code to remove most of it from the main page and moved it to a component

<SfGrid @ref="Grid">
    <GridEvents TValue="TItem"
                Filtering="FilteredHandler" Filtered="FilteredHandler" DataBound="DataBoundHandler" >
    </GridEvents>
</SfGrid>

<FilterPersistence @ref="filterPersistence" TItem="TItem" Grid="@Grid" pageURL="@pageURL"></FilterPersistence>

@code{
    private FilterPersistence<TItem> filterPersistence;
    public SfGrid<TItem> Grid;
    public string pageURL = "/Grid/URL/Example";

    public async Task DataBoundHandler()
    {
        await filterPersistence.SetFilter();
    }

    public void FilteredHandler(FilteredEventArgs args)
    {
        filterPersistence.SaveFilter();
    }

    public void FilterFields()
    {
        filterPersistence.SaveFilter();
    }
}
