Enum as data parameter

[Dang]

Is it possible to pass an enum as the data to the DropDownList? While testing I'm receiving an error [ERROR TypeError: "this.data.slice is not a function"].

Hi Corey,

In general, the DropDownList supports binding to an array of values only. The list can consist of primitive values or complex objects. For more details please check the following article from our documentation:

Let me know if I can provide any further assistance.

I build a helper method that will convert my enum to an object. I was hoping to avoid using a helper method, but this solution works fine. This will filter out all values where the key is not a number and map the enum to an object with key and text properties.

public convertEnumToObject(e: any): Object[] {
    return Object.keys(e)
      .filter(key => !isNaN(key[0] as any))
      .map(key => ({ value: key, text: e[key] }));
}

Hi Corey,

Thank you for the provided code snippet.

I am glad to hear that you have managed to resolve the discussed issue. Indeed in this situation using such a helper method is the way to go, considering the type of object that the DropDownList supports.
