  This could be a great solution for my problem.
  Indeed the RadComboBox work fine putside a RadGrid,
  but i need it to be inside a RadGrid inside the FormTemplate
  (as i am using EditForms in the EditMode) 
  and here i am having two problems :
  1. The entries dont show the text : i open the RadCombo and all i see are empty CheckBoxes
  2. I cant access the CheckBoxes after i close the RadComboBox :
  i find the RadComboBox through the Update event handler but i cant seem to access the checkBoxes
  please i need this urgently

  i am using your "Checkbox RadGrid + Button + Listbox "example inside a RadGrid wich makes it pretty complicated.
  i managed to make the RadCombo and the CheckBox work and it looks great
  but i still cant make the Button and ListBox work, they are all inside a RadGrid, its hard to find them in a Button_click event handler
  please help!
  again this is urgent
  best wishes

  Is RadComboBox feature available in VS2008?

• Nick Nick

  Hello Amruta,
  
  Yes, you can use the DLL residing in the bin folder of the NET2 directory in the installation (zip) files. It should properly run under VS 2008.

  how can you add Load on demand along with Multi item select

  "how can you add Load on demand along with Multi item select"
  
  I have the same question.

• Simon Simon

  Hi BC,
  
  In order to have the CheckBoxes fully retaining their state when clicking on them and at the same time using Load-On-Demand you need to somehow store the state of each Item on the server.
  
  For example, each Item record in a database could have an additional column - Checked/Selected.
  
  Then by using RadAjaxManager (or another control or approach offering a similar functionality) you could do an AJAX request upon clicking of an Item's CheckBox and update the Checked/Selected state of the Item in the database.
  
  Finally, Load-On-Demand, CheckBoxes and multi-item selection would be functional at the same time.
  
  Kind regards,
  Simon

  I need a solution similar to this, and have downloaded the code to try to play around with this, but am receiving the following error:
  
  Could not load file or assembly 'RadComboBox.Net2' or one of its dependencies. The system cannot find the file specified
  
  How do I get the appropriate trial dll to reference this? We've already purchased some of Telerik's products and have a valid license to the Telerik.Web.UI assembly.
  
  Please help so I can run this code to see if it is a viable solution for us.
  
  Thanks!
