Radzen Grid reload not working

Dear guys,

i am working with Grids. I have just a problem with "reloading" the grid after deleting one row. TableGrid.Reload() is just not working :frowning:

<RadzenGrid @ref="TableGrid" .....................

editing and saving are working fine!

What's the type of the collection bound to the DataGrid?

I hope you can decrypt it :slight_smile:

@if (Table == null)
{

Loading...


}
else
{
switch (EditTable)
{
    default:
        <h1 class="text-danger">Error</h1>
        <h2 class="text-danger">No Permission</h2>
        break;
    case 1:
        <RadzenGrid @ref="TableGrid" AllowFiltering="true" FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive" AllowPaging="true" PageSize="12" AllowSorting="true" Data="@TableData" Value="TableValue" TItem="Table">
            <Columns>
                <RadzenGridColumn TItem="Table" Property="as_req__priority" Title="Priority" Width="80px">
                    <EditTemplate Context="Priority">
                        <RadzenDropDown @bind-Value="TableValue.as_req__priority" TValue="int" Data="@TableData.Select(a=>a.as_req__priority).Append(10).Append(100).Distinct()" Style="margin-bottom: auto;width:100%" />
                    </EditTemplate>
                </RadzenGridColumn>
				
				
.................

    List<Table> Table;

Table is created from EFCore

You are using ToList() somewhere? Usually it is DbSet<>.

Yes exactly!

Dependency injection with a service to get the data

TableData = await service.Get();

Tableservice:

public async Task<List<Table'>> Get()

    {
        return await _DBContext.Table.ToListAsync();
    }

Table created with dbset

public class DBContext: DbContext
{
public DBContext(DbContextOptions options) : base(options)
{ }

    public DbSet<Table> Table { get; set; }

}

You may need to remove ToList() call and work directly with the DbSet.

If you’re using List<> you need additionally delete list row. List.Remove()
