Hi,
I use blazor wasm net core 6.
I have parent DataGrid where I used EditInLine and this main table is expandable.
I added child table for each Id of the main table. When I populate in the child table I have to change the page to update the child table. How to update the child table without changing the page? Thanks in advance

Hi @sblb

I have parent DataGrid where I used EditInLine and this main table is expandable.

From your description, it seems that you are using a third party DataGrid component, it is better to tell us which kind of DataGrid component you are using? Besides, since this issue relates third party DataGrid component, you could also ask for help from the third-party DataGrid component.

Hi I use Radzen components, RadzenDataGrid In razor page I tried to implement

 protected override async Task OnAfterRenderAsync(bool firstRender)
    {
        base.OnAfterRender(firstRender);
 
        if (firstRender)
        {
            await grid.ExpandRow(developers.FirstOrDefault());
        }
    }

I obtain this message

Blazor.webassembly.js:1  crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: Value cannot be null. (Parameter 'source')
System.ArgumentNullException: Value cannot be null. (Parameter 'source')
   at System.Linq.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)
   at System.Linq.Enumerable.TryGetFirst[SuiviBE](IEnumerable`1 source, Boolean& found)
   at System.Linq.Enumerable.FirstOrDefault[SuiviBE](IEnumerable`1 source)
   at ServiceDT.Client.Pages.Etude.OnAfterRenderAsync(Boolean firstRender) in C:\App\sbd\ServiceDT - Copie\ServiceDT\Client\Pages\Etude.razor:line 248

Have you an idea how I can update the page w/o action another page?
