Project created through VS2022's "Blazor Web App" template and I've installed MudBlazor.

I've copied this filterable Table example from the MudBlazor docs almost exactly:

Still can't get the filter event to trigger on key presses in the text field, event is only raised on page refresh. Starting to suspect it could be related to the render mode? The pagination isn't working either.

@page "/"
@rendermode InteractiveServer
@inject StockService StockService
@using StockSim.API.Models
@using StockSim.API.Services

<MudTable Items="@Stocks" Dense="true" Hover="true" Striped="true" Filter="new Func<Stock,bool>(FilterFunc1)">
    <ToolBarContent>
        <MudText Typo="Typo.h6">Stocks</MudText>
        <MudSpacer />
        <MudTextField @bind-Value="searchString1" Placeholder="Search" Adornment="Adornment.Start" AdornmentIcon="@Icons.Material.Filled.Search" IconSize="Size.Medium" Class="mt-0"></MudTextField>
    </ToolBarContent>
    <HeaderContent>
        <MudTh>Symbol</MudTh>

    </RowTemplate>
    <PagerContent>
        <MudTablePager />
    </PagerContent>
</MudTable>


@code {
    private string searchString1 = "";
    private IEnumerable<Stock> Stocks = new List<Stock>();

    protected override async Task OnInitializedAsync()
    {
        Stocks = await StockService.GetStocksAsync();
    }

    private bool FilterFunc1(Stock Stock) => FilterFunc(Stock, searchString1);

    private bool FilterFunc(Stock Stock, string searchString)
    {
        if (string.IsNullOrWhiteSpace(searchString))
            return true;
        if (Stock.Symbol.Contains(searchString, StringComparison.OrdinalIgnoreCase))
            return true;
        if (Stock.Name.Contains(searchString, StringComparison.OrdinalIgnoreCase))
            return true;
        return false;
    }
}

• I've answered but If that doesn't work then my follow up question is what options did you choose when you used the MudBlazor template to create the project. – RBee Commented Feb 23 at 17:42
• @RBee Thanks, just reviewed my options and realized I had to adjust the Routes element in App.razor to <Routes @rendermode="InteractiveServer" />. Working now. – SoroushAU Commented Feb 24 at 4:16

I reviewed the docs (https://learn.microsoft/en-us/aspnet/core/blazor/components/render-modes?view=aspnetcore-9.0#apply-a-render-mode-to-the-entire-app) and apparently had to add @rendermode="InteractiveServer" to the Routes and HeadOutlet elements in App.razor. I'm not entirely sure why this fixed it since my .razor was already using @rendermode InteractiveServer locally. Perhaps the rendermode needed to be set globally like that to support MudBlazor's components too? Not sure.
