Doncho,

FYI, As best I can tell I can tell, i am NOT using lightweight render mode.  Here is my Combo Box .aspx definition:

<telerik:RadComboBox ID="RadComboBox1" runat="server" DataTextField="FolderName" Width="95%" CausesValidation="false" DataValueField="FolderId" 
        EmptyMessage="Select a Folder" AllowCustomText="false" EnableScreenBoundaryDetection="false" BorderColor="Black" BorderWidth="1px" 
        style="border-radius:5px;" ZIndex="100000">
        <Items>
            <telerik:RadComboBoxItem/>
        </Items>
        <ItemTemplate>
            <telerik:RadTreeView ID="rtFolders" EnableNodeTextHtmlEncoding="true" ShowLineImages="false"
                runat="server"
                CausesValidation="false"
                Style="min-height: 200px; overflow: hidden;"
                AppendDataBoundItems="True"
                OnClientNodeClicking="nodeFolderClicking" />
        </ItemTemplate>
    </telerik:RadComboBox>

This is the first combobox that is shown in my video, (not the second that was in a modal popup window).  

I was ONLY able to fix the issue when I added the standard ComboBox css to the page.  The fix did NOT work for me when I added the lightweight version.

Thank you for the detailed video, Mark!

Yes, it is the same problem as the one originally reported in this thread.

Until our next release, I would recommend using the workarounds suggested in my previous comment.

The issue is only replicable in Lightweight render mode but not in Classic. Based on the ComboBox appearance in the provided screencast it seems that the Combo is in Lightweight render mode in your case as well. You can find more about the RenderModes here:

By using the StyleSheetReference you shared, the ComboBox Bootstrap styles for Classic RenderMode are loaded on the page. This might be partially fixing the look of the control, but these styles are designed to be used with the Classic mode rendering hence this could lead to some other appearance issues.

Kind regards,
Doncho

This issue affects both the bootstrap lightweight and normal bootstrap skins.  

 

this is fixing the issue for me currently. i put this in my master page.

 

    <telerik:RadStyleSheetManager runat="server" ID="radStyleSheetManager1" EnableStyleSheetCombine="true" >
        <StyleSheets>
                <telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.Bootstrap.ComboBox.Bootstrap.css" Assembly="Telerik.Web.UI.Skins" />
        </StyleSheets>
    </telerik:RadStyleSheetManager>

Hi,

The stylesheet holding the RadComboBox styles for Bootstrap skin in Lightweight RenderMode is not loaded due to a wrong file name.

As a temporary workaround you can load the needed stylesheet manually on the page:

Option 1

Use RadStyleSheetManager to load the correct stylesheet from Telerik.Web.UI.Skins assembly, as per the instructions in Skin registration with RadStyleSheetManager:

<telerik:RadStyleSheetManager runat="server" ID="RadStyleSheetManager">
    <StyleSheets>
            <telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.BootstrapLite.ComboBOx.Bootstrap.css" Assembly="Telerik.Web.UI.Skins" />
    </StyleSheets>
</telerik:RadStyleSheetManager>

Option 2

Link the correct stylesheet manually on the page in one of the following ways:

Kind regards,
Doncho
