What's the type of the collection bound to the DataGrid?
I hope you can decrypt it
@if (Table == null)
{
Loading...
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 youβre using List<> you need additionally delete list row. List.Remove()
Thank you !! Now it is working.
Hi @enchev
Question:
If I remove the ToList()
from the call, I will have an "invalid cast" error.
From the demo code:
@code {
RadzenDataGrid<Order> ordersGrid;
IList<Order> orders;
IEnumerable<Customer> customers;
IEnumerable<Employee> employees;
protected override void OnInitialized()
{
base.OnInitialized();
// For production
orders = dbContext.Orders.Include("Customer").Include("Employee"); // β invalid cast from DbSet<Order> to Generic.List<Order>
}
You cannot assign IEnumerable to IList, you should change the type of the orders
field if you do not want to call ToList()
your answer saved me, thank you very much!!
