Using RadComboBoxData to Populate RadComboBox

[Amit]

Hi,

I have a RadComboBoxData object with all the data items. How can use it to populate RadComboBox?

[Amit]

I acheived the required result using the following code:

protected void rcbPerson_ItemsRequested(object sender, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)
       {
           RadComboBoxData d = PersonBO.GetPersons((RadComboBoxContext)e.Context);
           rcbPerson.DataSource = d.Items.AsEnumerable();
           rcbPerson.DataTextField = "Text";
           rcbPerson.DataValueField = "Value";
           rcbPerson.DataBind();
           e.Message = d.Message;
       }

Is there a better way of doing it?

Thanks for your reply Kalina. I don't want to use webservice because after deployment on server it was running too slow. I posted another thread for this problem (http://www.telerik.com/community/forums/aspnet-ajax/combobox/radcombobox-too-slow-when-deployed-to-server.aspx) but no one replied. So I replaced web service with the direct combobox population in code behind.

Hello Amit,

In general you can continue using the approach you've posted below, or you can simplify your code by implementing a Server-Side Load On Demand - as is demonstrated here.
