Radmenu causing javascript error preventing showing children

I am getting the following javascript error when my radmenu loads : Error:Unable to get property 'addEventListener' of undefined or null reference

This causes some (not all) of the children menu items to not show up. Only 2 dropdowns (children) work and the rest do not drop down.

Is there any way to fix this? I have tried so many things but no luck.

Using IE 11 ASP.net 2.0 C# code.

thanks,

Radmenu.js file where should I define this and how?

In VS I am using Telerik.Webcontrols Assembly="Radmenu.Net2" which allows me to do this:

in the ascx file:
<%@Register TagPrefix="radm" Namespace="Telerik.WebControls" Assembly="RadMenu.Net2" %>

<radm:radmenu runat="server" id="mymenu" skinspath="~/app_themes/Normal" skin="Radmenu" width="100%" OnItemDataBound="mymenu_ItemDataBound" RadControlsDir="~/Public/RadControls/" />

Which I thought RadControlsDir leads me to Radmenu.js (in folder Public/RadControls/Menu/Scripts/4_4_6/RadMenu.js) but even when I rename this js file, it is still showing the menu. Am I not looking in the right place? In this folder "RadControls" there are these subfolders:
Ajax
Editor
Grid
Menu
Rotator

No matter what I remove it doesn't budge. I am thinking the referenced directory path is somewhere else. Can you tell me where????

thanks

Reset Page Index with RadDataPager

I have a RadListViewcontrol that I bind to data. I am also using two RadDataPager controls at top and bottom. The binding works and the paging works. However, when I rebind the list and the pager are set to a page outside of the results, the page disappears. I tried using fireCommand("Page", "First") and set_currentPageIndex(1) on the client before I bind, but they are not working. They error out in the jscript that the methods do not exists. I am using version 2010.2.929.40 of the DLLS. I am using NeedDataSource for binding. I cannot seem to find a server method to reset page number.

Cannot Find RadGrid when in a RadPanelBar

I am having difficulty with the Persistence Framework. My application has a master page and the RadGrid is in a content page. When the RadGrid is at the root of the page (i.e. just under asp:Content), I can save/load the grid settings with no issue whatsoever. But that's not where I want my RadGrid. I want it in a RadPanelBar. And when I have it there, the Persistence Framework says it cannot find the control.

Here is some simplified code. This first part works:

<telerik:RadPersistenceManagerProxy
        ID="m_PersistenceManagerProxy"
        UniqueKey="ClaimswebFinancialsPayables"
        runat="server">
        <PersistenceSettings>
            <telerik:PersistenceSetting ControlID="m_rgPayables" />
        </PersistenceSettings>
    </telerik:RadPersistenceManagerProxy>

<telerik:RadGrid
ID="m_rgPayables"
runat="server"

... et cetera. But when I put the RadGrid in a RadPanelBar, the Persistence Manager says that it cannot find the control. Specifically if I put the RadGrid inside the ContentTemplate of a RadPanelItem.

Any ideas? I feel like I'm so close.

Problems after 2017 Upgrade

Hi,

I recently upgraded my application from the 2016 controls to the 2017 R2 controls and now I'm having issues with the Combobox and how it displays on the screen.

My combobox is within an Editform / form template of a RadGrid. It is defined this way:

<code>

<telerik:RadComboBox ID="rddRouteInner" runat="server" DataTextField="route" DataValueField="route"
DropDownHeight="200px" DropDownWidth="350px" AllowCustomText="true" Font-Size="12px" >
</telerik:RadComboBox>

</code

Very simple - no CSS applied or anything else. I added the Font-Size="12 px" because the font in the input was different from the drop down since the upgrade - which seems kind of crazy - but not a big deal.

Attached is what the output looks like. The Input Box is taller than the surrounding drop down box - and I get multiple drop down boxes (at least started). I have no idea how to troubleshoot this - when I just put a combobox on a page by itself - it works correctly.

Help?

Thanks!!!

ComboBox Custom Skin is not working after 2017 Update

We recently upgraded to 2017 Telerik for a project which had 2014 before.

ComboBox has custom skin, and it is not displaying correctly after update. After following a response on a different thread, i applied lightweight render mode for only combobox in config, which fixed the layover of image. But, it is not picking up the custom skin after that fix. Please advise.

Images attached here.
