I don't understand what setting or property of the menu or menuitems will cause ALL the dropdown menus to left-align.

My dropdowns always align under the top-level item.

I was able to acheive left alignment by doing this CSS hack. But this cant be the right way of doing this. My page is here:

http://kw.my.etghost.net

.Item1 .rmSlide
   {
       left: 0px !important;
   }
.Item2 .rmSlide
   {
       left: -170px !important;
   }
.Item3 .rmSlide
   {
       left: -340px !important;
   }

Problems with creating dynamic columns

I have a radgrid I am creating dynmically including an editcolumn but when I click on the edit Column button I get the following error?

"An error has occurred because a control with id 'dgCompGrid$ctl00$ctl04$EditButton' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error."

I have changed the grids viewstate = True but still get the same error?

        With dgCompGrid
            .Columns.Clear()
            .DataSource = Nothing
            .EnableViewState = True
            .DataSource = ippService.Select(ID)
        End With

        Dim oEditColumn As New GridEditCommandColumn
        With oEditColumn
            .ButtonType = GridButtonColumnType.ImageButton
            .UniqueName = "EditColumn"
            .CancelImageUrl = "~/Images/small/x_out.gif"
            .EditImageUrl = "~/Images/small/pencil.gif"
            .UpdateImageUrl = "~/Images/small/save_blue.gif"
            .ItemStyle.Wrap = False
        End With

dgCompGrid.MasterTableView.Columns.Add(oEditColumn)

If I comment out the buttontype were the column shows EDIT instead of an image button it have no problems?

I use the Needdatasource to call a sub that loads the data.

Thanks in Advance.

How do I handle sliding session timeout with RadNotification

I am using the RadNotification control to notify the user of their session timeout due to inactivity. I am basically following the example from the demo on the site. But notification keeps showing even if there was ajax calls that keeps the session alive. I couldn't find any documentation on handling sliding session timeouts with radnotification control.

Selected Item is Displayed Blank on IE, but not Chrome

I'm using VS 2012 on Windows 8. Works fine on Chrome, but when I'm using IE it's blank every time I manually select it. If I set it programatically at the start then I can see it. Or if I set AutoPostback=true, then I can see it too.

I'm just using a dictionary to fill my combo box

<telerik:RadComboBox ID="rcbSeasonsFilt"

EmptyMessage="Change Season" DataTextField="Key"

runat="server" DataValueField="Value" />

EDIT, I'm using q1 2013 asp.net 4.5 v 2013.1.220.45

webresource references missing

I have deployed an ASP.Net app that uses ASP.Net Ajax controls to different servers in different environments and all is fine with the exception of one page within the site that the Telerik controls do not appear correctly.

I've examined the source for the page that works and the page that doesn't and the only difference is the fact the in the head section there are two <link> WebResource references missing on the page that does not work. For reference, the controls that do not display correctly are used on other pages in the site and they display correctly.

If have compared every file in the site (source, DLL, etc.) and they are all identical from server to server.

Any idea why certain WebResource references would not be generated on one server but would be on another?
