Hello Support,

​We are experiencing very sluggish rendering behavior when using Rad Editor Control in Rad Window when browsed from IE browser.
Please find few image screenshots to explain the issue.

Test environment:
Telerik version: 2015.1.401.45
Chrome: 44.0.2403.130
IE: 11.0.9600.17905

It seems that page CSS files are being retrieved multiple times from the server in all browsers but in IE, files are retrieved twice or more than twice. Hence slows down the whole page in IE browser.

Brief information about existing application (I don’t think it is related to Kentico environment which we are using):

• user control (deployed as Kentico webpart) which is added to Kentico Page
• has RadGrid for listing items.
• editing item from the grid, pop-ups Rad Window.
• Rad Window has editable form fields along with 7 Rad Editors

Investigation so far:

• Remove rad Editors from the rad window – No duplication of the CSS files
• Specified “EditorCssFile” as well as “CssClasses” – Still retrieves CSS files

Need your help to fix the rendering/retrieving difference between browsers as well as any workaround to stop retrieving CSS files multiple times.

Please let me know if you need any other information.

Thanks.

Using the Telerik skin throughout our site but using the Black skin for our Tabstrips.  Have the requirement to change the color of non-selected tabs.  Is it possible to still utilize the skin but change just this one element?  In the image attached, need to lighten the background color of the "Dates" tab.

I am running an older version of the controls and have an issue where our internal intranet servers default IE behavior to run in Compatibility mode.

Telerik Version: 2012.3.1308.40 

This is breaking the alignment of my grids headers. The left most header has a empty column name. The rest of the columns headers are populated. 

 In the Screen shot you'll see how the "Plan" column header text is pushed to the left overlapping the top of my row headers. If I go into tools -> Compatibility View Settings and uncheck the option to run the browser in compatibility mode for all intranet sites the columns render just fine.

Any ideas on what this might be?

Hi

I have been searching all over for a solution to this problem and have not found a thing. I have a horizontal RadMenu that I am manipulating via the Telerik Client Side API. The RadMenu is created server side. This menu is dynamic so it can have however many items the user defines it to have.

 What I would like to do is, take X Rad Menu Items after the 6th item and add them under a parent RadMenu Item using the Telerik Client Side API. It is very easy to add an item to the menu, but I have not found a solution to add a child item to a parent item. Here is my code.

<script> 

function AddMenuItems() {

            var menu = $find("<%= testMenu.ClientID %>")
            menu.trackChanges();

            var parentItem = new Telerik.Web.UI.RadMenuItem();

            parentItem.set_text("More...");
            menu.get_items().add(parentItem);

            var childItem = new Telerik.Web.UI.RadMenuItem();
            childItem.set_text("child");
    menu.get_items().insert((menu.get_allItems().length), childItem);
            menu.commitChanges();
        }

    </script>
    
    <AxnMenus:AxnMenu ID="testMenu" runat="server" OnClientLoad="AddMenuItems">
    <Items>
        <AxnMenus:AxnMenuItem Text="item 1" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 2" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 3" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 4" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 5" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 6" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 7" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 8" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 9" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 10" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 11" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 12" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 13" runat="server"/>
    </Items>
    </AxnMenus:AxnMenu>

Hi

 I have been using the Client Side API and also looking all over the internets for a solution to this problem and have not seen a thing.

 I have a RadMenu that is created dynamically server side. This menu can have as many menu items as the user defines. I would like to add a child menu item to a parent menu item via Telerik's Client Side API. 

The Add and Insert functions both seem to add the item to the menu as a parent instead of adding the child item inside of the parent menu item. Is there a way I can add the child item to the parent item, so that it displays within the parent items drop down? Ultimately, I would like to create a multilevel drop down.

 Here is some test code I have written, to see if this is possible.Thanks!

<script> 

    function AddMenuItems() {
            var menu = $find("<%= testMenu.ClientID %>")
            menu.trackChanges();

            var parentItem = new Telerik.Web.UI.RadMenuItem();

            parentItem.set_text("More...");
            menu.get_items().add(parentItem);

            var childItem = new Telerik.Web.UI.RadMenuItem();
            childItem.set_text("child");
            menu.get_items().insert((menu.get_allItems().length), childItem); <== Adds the item after the parent item instead of inside. 
            menu.commitChanges();
        }

    </script>
    
    <AxnMenus:AxnMenu ID="testMenu" runat="server" OnClientLoad="AddMenuItems">
    <Items>
        <AxnMenus:AxnMenuItem Text="item 1" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 2" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 3" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 4" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 5" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 6" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 7" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 8" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 9" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 10" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 11" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 12" runat="server"/>
        <AxnMenus:AxnMenuItem Text="item 13" runat="server"/>
    </Items>
    </AxnMenus:AxnMenu>

Hello.

I'm currently experiencing issues with the Schedulers PDF-export function. It seems that i can not set the ShowHourColumn to invisible properly, making it render the hour column in the pdf export. I do not wish for it to do this. Also, the export creates some sort of mashed together rows at the top of every page (starting at page 2 and onwards). I'm attaching an image to better show the issues that I'm experiencing. 

#1 is the mashed-rows, they contain actual data that needs to be display.

#2 is the hour column, i want to hide it in the export.

 Here's the code for exporting it.
