Hi, I've a problem with the visibility of items of a RadCombobox in a grid insert in a Notification.
When I press click on RadComboBox I see only items that exit from Notification (Attach File).

This is my Notification
<telerik:RadNotification ID="RadNotification1" runat="server" ContentIcon="../../Images/Notification/check_48.png"
        Position="Center" AutoCloseDelay="15000" Width="600" Height="250px" Pinned="true"
        EnableRoundedCorners="true" EnableShadow="true" KeepOnMouseOver="true" VisibleTitlebar="true"
        ShowCloseButton="true" Animation="Fade" AnimationDuration="200" Skin="Web20"
        TitleIcon="../../Images/Notification/check_16.png">
        <ContentTemplate>
            <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="false" OnItemDataBound="gvDesignazione_ItemDataBound">
                <MasterTableView>
                    <Columns>
                        <telerik:GridTemplateColumn>
                            <ItemTemplate>
                                <%# Eval("INFOBASE")%>
                            </ItemTemplate>
                        </telerik:GridTemplateColumn>
                        <telerik:GridTemplateColumn>
                            <ItemTemplate>
                                <telerik:RadComboBox ID="ddlDesignazione" runat="server" Skin="Office2010Blue" Width="180px"
                                    ZIndex="1000">
                                </telerik:RadComboBox>
                            </ItemTemplate>
                        </telerik:GridTemplateColumn>
                    </Columns>
                </MasterTableView>
            </telerik:RadGrid>
        </ContentTemplate>
    </telerik:RadNotification>

Hi Lupotana,

This happens because the dropdown of the RadComboBox is another popup element (with absolute positioning) on the page and thus the z-index rules apply to it. By default the RadNotification has a high z-index (10000) and this is the reason why the dropdown is behind it. A list with the default values and a proposed solution is shown in the following help article: http://www.telerik.com/help/aspnet-ajax/controlling-absolute-positioning-with-zindex.html.


Kind regards,
