RadzenDropDown with Enum Cast not valid

Keep receiving the following error Cast not valid when switching values
OrderStyle is an enum with 3 values
public enum OrderStyle {Simple,Fast,Slow}

What's the correct approach for a drop down with enums, that you want associated to the new object (i.e. if you were creating a new order)

Hi @iamthemarkus,

This demo shows a working usage of DropDowns and enums: https://blazor.radzen.com/styling-chart

The code is mostly like this:

<RadzenDropDown Data="@colorSchemes" @bind-Value="@colorScheme" />
@code {
    IEnumerable<ColorScheme> colorSchemes =  Enum.GetValues(typeof(ColorScheme)).Cast<ColorScheme>();
    ColorScheme colorScheme = ColorScheme.Palette;
}

I can see that this works in general and I've managed to correct my case.

One perhaps not expected behavior was that because my enum values have numbers associated to them
the method suggested will cause the number to be displayed in the drop, then rendered as the name representation once selected.

Bumping thread as I have the same issue.

When binding to an enum and the drop down list shows the Value instead of the Name of the enum.

I tried copying the example provided by @korchev and it shows the Values as well.

My enum...
protected Grid.Modes SelectedMode = Grid.Modes.Small;
protected IEnumerable<Grid.Modes> GameModes = Enum.GetValues(typeof(Grid.Modes)).Cast<Grid.Modes>();
public enum Modes { Small, Medium, Large }
<RadzenDropDown Data="GameModes" @bind-Value="SelectedMode" Style="margin-bottom: 20px" Change="GameModeChanged" />

Another note is that I am running in WASM and not Server Hosted.

I guess Enum.GetValues works differently in server-side blazor and returns string values. Frankly I am not sure this is related to Radzen. What happens when you use a regular <select>?
