Question

I have a combobox that is bound to an enum using the following code:

cmb.ItemsSource = Enum.GetValues(typeof(DATABASE_TYPES)).Cast<DATABASE_TYPES>();

where DATABASE_TYPES is:

public enum DATABASE_TYPES
        {
            JDataStore, Access, SQLServer, H2, PostGresSQL, MySQL
        };

I have some xml that matches one of the enum values:

<property name="Database.Main.Type"
        type="databaseType"
        default="JDataStore"
        permissions="superuser">
    </property>

I am trying to programmatically set the selected item of the combobox to the default value from the xml.

I have tried:

cmb.SelectedItem = propertyNode.Attributes["default"].Value;

but this doesn’t work.

Could someone please advise?

You need to convert the string to an enum instance:

cmb.SelectedItem = (DATABASE_TYPES)Enum.Parse(typeof(DATABASE_TYPES), propertyNode.Attributes["default"].Value);
