    When there is no item in RadComboBox i did't want check all option.

    <telerik:RadComboBox ID="RadComboBoxSites" runat="server"  OnClientItemChecking="OnClientItemChecking"  CheckBoxes="true"  EnableCheckAllItemsCheckBox="true" DataTextField="SiteName" DataValueField="SiteUid" AppendDataBoundItems="true" OnItemDataBound="RadComboBoxSites_ItemDataBound" DropDownWidth="250px"OnClientDropDownOpening="disableComboBoxSeparator;disableCheckall" EmptyMessage="Please select a site..." MaxHeight="192px">

    Hi Jackson,

    You can use the following approach to achieve this requirement:
    protected void RadComboBox1_DataBound(object sender, EventArgs e)
        RadComboBox combo = sender as RadComboBox;
        combo.EnableCheckAllItemsCheckBox = combo.Items.Count > 0;

    Hope this helps.
