I using radComboBoxs in my application. When ever the number of items increasing, it is not showing the drop down. I am using the "Default" skin for this. Even the combo border is also missing.

<telerik:RadComboBox ID="RadComboBox2" Skin="Default" EnableEmbeddedSkins="False"
        runat="server">
        <Items>
            <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1" />

        </Items>
        <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
    </telerik:RadComboBox>

Please help me out in fixing this issue.
Asp.net DropDownList is showing the dropdown whenevr the number of items increasing.
I believe it is because of EnableEmbeddedSkins="False". I need to set this as false always and bring the dropdown for the combo. 

Thanks in advance
Raj

Hi Raj,

Does it work when EnableEmbeddedSkins is set to true? Why do you need to disable embedded skins? Have you registered the required skin css as expected?

Hi Albert ,

Thanks for the reply.

It is working now. The scroll bar properties were missed in the CSS files I copied to my Project and I added those section, it is working fine now.

Thanks.
