Re: Trying to Bind DropDownList to enum within a FormView

Hi ericjvanpyrz,

Based on your last post, it seems you have solved original issue. If you want to convert enum to index, you could write a function to convert enum to int32 array.

I created the sample for you, code shown below:

public static Int32[] ConvertEnumToIndex<K>()
{
    if (typeof(K).BaseType != typeof(Enum))
    {
throw new InvalidCastException();
    }
    return Enum.GetValues(typeof(K)).Cast<Int32>().ToArray();
}

protected void FormView1_DataBound(object sender, EventArgs e)
{
    DropDownList DDL = (DropDownList)FormView1.FindControl("DDL1");
    DDL.DataSource = ConvertEnumToIndex<ListingStatus>();
    DDL.DataBind();
}

public enum ListingStatus { Negative = -1, Zero = 0, Positive = 1 };

Like below:

Best Regards,
