Hi Oscar Zapata,

You can iterate all items from Items property.
foreach(object item in this.radComboBox1.Items)
{
   // Do something.
}

If you add RadComboBoxItem in the Items collection (your case) then you can cast item to RadComboBox or else item will be of the type you added in Items.

Let us know if you need more help.

I'm unable to access each item as a RadComboBoxItem, instead the type being returned is string.  I tried casting as you suggest but no luck.  

 

private void ddlFilterBy_Loaded(object sender, RoutedEventArgs e)
{
    foreach (RadComboBox item in ddlFilterBy.Items)
    {
        item.Foreground = new SolidColorBrush(Colors.MidnightBlue);
    }
}

 

This results in exception: can't convert System.string into telerik.RadComboBoxItem. 

Thanks for your help

Hello Mark,

This should be working as expected if you use static items. However if you are using an ItemsSource, for example List<string> then Items collection will return you items of type string. In such scenario you will be able to change just the Data object which is string in your sample.

If you want to change the background of the ComboboxItems you may need to use ItemTemplate as shown in this example.
