    I have used RadComboBoxes inside a Grid in my WPF application as shown below.
    tk:RadComboBox Grid.Row="3" Grid.Column="3" Style="{StaticResource DropDown}"
                           x:Name="cmbColor" Height="25" Margin="5,5,5,5" DropDownOpened="cmbColor_DropDownOpened"
                           IsEditable="False" SelectedValue="{Binding PR_COLOR}" MaxWidth="250"
                           ItemTemplate="{StaticResource DropDownCodeMeaning}"  />

    I am binding the data to the combo box when the user clicked on the combo box to select an item from it.
    I have used the  event
    "DropDownOpened" to bind data to this combo box. Below shown is the code behind.

    // set the dropdown list for a combobox to all entities for a business object
           private void SetDropDown<BusObj, BusEntity>(RadComboBox cmb, ref BusObj busobj)
               where BusObj : BusinessObject<BusEntity>, new()
               where BusEntity : BusinessEntity, new()
               if (busobj == null)
                   busobj = new BusObj();
               if (cmb.ItemsSource == null)
                   var RecordList = busobj.GetAllEntities();
                   if (RecordList.Count > 0)
                       RecordList.ApplySort("SortKey", ListSortDirection.Ascending);
                   cmb.ItemsSource = RecordList;
    After sets the Items Source for the combo box, the memory increases rapidly. Anyone knows why this happens?
    Please help me. I am using the telerik version 2010.1.603.35.

    Thanks in advance,
