@bind-Value when creating a loop of RadzenDropDown

Hello all,

I have a scenario I'm not sure how to solve while creating a loop of RadzenDropDown components. When trying to use @bind-Value with a loop, all of the drop downs get assigned the same variable and when you change selections in one drop down, it changes the others. Is there a way to solve this in a loop? Using the Change event would seem to be the next best option, but I don't understand how to pass the ValueProperty to that event.

@foreach (var dataFilter in DataFilterList)
        <div class="col-lg-2">
                Change="@(args => OnChange(args, dataFilter.FilterId))"

Attempting to use the method in the example:

void OnChange(object value, int FilterValueID)
        var str = value is IEnumerable<object> ? string.Join(", ", (IEnumerable<object>)value) : value;

        Log.Information($"Value changed to {str}");

Results in this output:


I'm sure I'm doing something incorrect, and any assistance would be greatly appreciated! Please let me know if you need any additional information!

You need to specify a separate property or field per dropdown e.g. by using an array.

The value argument that you receive should contain the right value property already. You can use the debugger to inspect what it is.
