Hi Sankar,

To populate RadComboBox from a collection, you need to set the control's ItemsSource property. To specify which is the initially selected item in RadComboBox you need to set SelectedIndex or SelectedItem properties. I am not sure that I understand the question correctly, please, let me know if my answer does not provide a solution for your problem.

Kindly let us know how to set Key & Value for the Drop down list similar to ASP.NET

Hello Sankar,

The Silverlight controls do not provide the ability to set Key/Value for their items. Instead, it the control is databound you could directly access the data item of the selected RadComboBoxItem:

List<Product> products = new List<Product>();
products.Add(new Product() { ID = 1, Name = "Product1", Description = "Short description 1" });
products.Add(new Product() { ID = 2, Name = "Product2", Description = "Short description 2" });
products.Add(new Product() { ID = 3, Name = "Product3", Description = "Short description 3" });
// You could populate the products list from a service instead
// but the code, related to RadComboBox will be the same
RadComboBox1.ItemsSource = products;
...
private void RadComboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    Product selectedProduct = RadComboBox1.SelectedItem as Product;
    //You can access all properties of the actual Product object that is bound to
    // currently selected RadComboBoxItem
    ...
}

I hope this helps.

All the best,
