Hello,
I have this snippet in a new NET8 Blazor Project (Interactive Server)
@page "/test"
@rendermode @(new InteractiveServerRenderMode(prerender: false))
<h3>Testdropdown: </h3>
<RadzenDropDown @bind-Value=multipleValues Data=@customers Change="@OnChange"
AllowFiltering="true" FilterCaseSensitivity="Radzen.FilterCaseSensitivity.CaseInsensitive"
Name="DropDownMultipleChips"
Multiple=true AllowClear=true Placeholder="Placeholder" AllowSelectAll="true"
TextProperty="Text" ValueProperty="Value"
Chips=true />
@code {
IEnumerable<DropDownItem> customers;
IEnumerable<string> multipleValues;
protected override void OnInitialized()
{
customers = new List<DropDownItem>() { new DropDownItem("A", "1"), new DropDownItem("B", "2") };
}
void OnChange(object value)
{
var str = value is IEnumerable<object> ? string.Join(", ", (IEnumerable<object>)value) : value;
Console.WriteLine($"Value changed to {str}");
}
}
The search and selection works fine if I search with keyboard and click the option with a mouse. But when I filter and try to select an option with the arrow keys + enter, following exception is thrown:

Any idea how I can fix this or if I'm using something wrong?
