Virtual Scrolling Not working as expected

[Platinum]

Hi,

I am using Telerik Asp.Net for Ajax version 2014.3.1024.40.

I have enabled virtual scrolling the drop down list as below. I am able to see only the Afghanistan, all the others are shown as blank value. However i disable the virtual scrolling, i am able to see all the entries. Please let me know whats the issue and how to fix it ?

<telerik:RadDropDownList ID="rdlCountry" DefaultMessage="---" EnableVirtualScrolling="true"  runat="server"  >
                                                            <Items>
                                                                <telerik:DropDownListItem Text="Afghanistan" />
                                                                <telerik:DropDownListItem Text="Albania"  />
                                                                <telerik:DropDownListItem Text="Algeria" />
                                                                <telerik:DropDownListItem Text="Andorra" />
                                                                <telerik:DropDownListItem Text="Angola" />
                                                                <telerik:DropDownListItem Text="Antigua & Deps" />
                                                                <telerik:DropDownListItem Text="Argentina" />                                                             
                                                            </Items>
                                                        </telerik:RadDropDownList>

Hello,

In order to achieve the proper behavior of the control, when the VirtualScrolling is enabled you need to set the DropDownHeigth of the RadDropDownList, so that the control could correctly calculate the portion of items to load. This is described in our help article below:
