Hello salih,

As far as I understand - you are trying to use the CheckBoxes along with Load On Demand feature.
I am afraid that this is not a supported scenario - please find more details about this topic here.

I am suggesting you test the RadComboBox behaviour under different configurations at this online demo.

In the Project which can be reached by the link below, 
Comboboxes’ checked property values are made TRUE  and I embedded this code after the button;
http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx
Although radcombobox2’s items are chosen, the combobox.checkeditems count still seems “0(null)”.

private static void ShowCheckedItems(RadComboBox comboBox, Label label)
       {
           var sb = new StringBuilder();
           var collection = comboBox.CheckedItems; ----- count 0


           foreach (var item in collection)
               sb.Append(item.Text + "<br />");


           label.Text = sb.ToString();
       }


       protected void Button1_Click(object sender, EventArgs e)
       {
           ShowCheckedItems(RadComboBox2, itemsClientSide);
       }
