I'm trying to load a grid control with data from a stored procedure using entity framework and I'm getting the following error: " The ObjectContext instance has been disposed and can no longer be used for operations that require a connection".    I had been using the commented out code below, which works, but wanted to use Entity Framework to call the stored procedure.  I've tried the code with and without the databind() without any difference.  the code for one of the stored procedures.  I have several other calls to stored proc's, which are called to Entity Framework that work fine, but they return distinct data values.  Any help appreciated.

Hi Telerik Team ,

I have been trying hard to save the data in Radgrid as word, excel, pdf formats.
I am successful in doing that using the radgrid - Exporting method.
But along with save, it also exports due to which we get the popup asking to save or open the file.
We can use Response.Redirect(Request.UrlReferrer.ToString()) to prevent the popup. But it doesnot seem handy in my situation.

My question is is there any workaround. Can I try it using telerik report viewer object ?
Can we make the use of report viewer exporting functionality to achieve what I need to ?
Any solution to my problem would be appreciated.

Thanks in advance ,
Anurag

Anyone else get this warning in dev console for chrome 39

The specified value '11/24/2014' does not conform to the required format, 'yyyy-MM-dd'.

Also, the chart labels are now not aligned. This was never an issue in chrome 38.

See screenshot below.

I am using ASP:TabContainer with ASP:Panel and ran into problem with refresh.  I could not refresh just the tab, only the only page - I really need just a tab refresh. 

So, I though I would tryRadTabStrip.

<%@ Register Src="~/Admin/GroupBasics.ascx" TagName="GroupBasicsCS" TagPrefix="uc" %>
<%@ Register Src="~/Admin/GroupForm.ascx" TagName="GroupFormCS" TagPrefix="uc" %>
<%@ Register Src="~/Admin/GroupMemberPage.ascx" TagName="GroupMembersPageCS" TagPrefix="uc" %>
<%@ Register Src="~/Admin/GroupMembers.ascx" TagName="GroupMembersCS" TagPrefix="uc" %>
...

    <telerik:RadTabStrip ID="GroupTabStrip" runat="server" OnClientTabSelecting="" AutoPostBack="false"  r Align="Justify" MultiPageID="GroupTabPV" SelectedIndex="0">
            <Tabs>
                <telerik:RadTab PageViewID="GroupBasicsPV"   Text="Group Basics"></telerik:RadTab>
                <telerik:RadTab PageViewID="GroupFormPV" Text="Group Form"></telerik:RadTab>
                <telerik:RadTab PageViewID="GroupMembersPagePV" Text="Group Members Page"></telerik:RadTab>
                <telerik:RadTab PageViewID="GroupMembersPV" Text="Group Members"></telerik:RadTab>
            </Tabs>
    </telerik:RadTabStrip>
      <telerik:RadMultiPage runat="server" ID="GroupTabPV" SelectedIndex="0">
            <telerik:RadPageView runat="server" ID="GroupBasicsPV">
                GroupBasicsPV
                <div class="contentWrapper">
                    <uc:GroupBasicsCS runat="server" ID="GroupBasicsCS" />
                </div>
            </telerik:RadPageView>
            <telerik:RadPageView runat="server" ID="GroupFormPV">
                GroupFormPV
                <div class="contentWrapper">
                    <uc:GroupFormCS runat="server" ID="GroupFormCS" />
                </div>
            </telerik:RadPageView>
 
            <telerik:RadPageView runat="server" ID="GroupMembersPagePV">
                GroupMembersPagePV
                <div class="contentWrapper">
                    <uc:GroupMembersPageCS runat="server" ID="GroupMembersPageCS" />
                </div>
            </telerik:RadPageView>

            <telerik:RadPageView runat="server" ID="GroupMembersPV">
                GroupMembersPV
                <div class="contentWrapper">
                    <uc:GroupMembersCS runat="server" ID="GroupMembersCS"/>
                </div>
            </telerik:RadPageView>
       </telerik:RadMultiPage>

With this setup if I try to open a RadEditor in the window I get a document not defined error:

Type.registerNamespace("Telerik.Web.UI.Editor");
Uncaught TypeError: Cannot read property 'document' of null 
in some Telerik code:
(function(a,b,c){b.RestorePoint=function(e,d){this.Window=e;
this.Document=e.document;
this.container=(d)?d:this.Document.body;

AND

when a do a refresh it not only refreshes the whole page, but it also changes the tab back to the first one.  It is also annoying that all the pages in the tabs are called on page creation before their tabs are clicked, potentially a huge waste of resources. 

There is might be a way to work around all this but the examples and documentation completely lack using an ascx collection. I would have thought a rather normal use.  I am probably doing it all wrong but I could only find one example with ascx's, TabStrip - Render Selected Page Only .  I probably need to control the tab strip more directly which I would pursue but the Document not defined error kind of kills using the TabStrip at all. 

Hi Support,

I am using UI for ASP.NET AJAX Q3 2014.
When I place a slider in a table: <table><tr><td><telerik:RadSlider ... /></td></tr></table>
then the styles are not fully rendered.
Sometimes at page load but not when you press the browser's refresh button.
This problem occurs on IE 11 but not in Chrome.
Is telerik not cross browser compatible?
Is telerik generally not made for IE 11?
Do you have generally problems with including components in a table cell?

Thanks for a Feedback.

I'm using the RadSiteMap in the context of the sitefinity breadcrumb widget...

So I've overrode the widget itself and have tried everything I can think of to stop the script from loading, but nothing seems to work.

Basically I just need to render out flat markup I dont need any client features of the widget...


Is it possible?

Visual Studio 2013 throwing exception "Telerik VSExtension Error" during upgrade wizard of Asp.Net application. Please see attached image.
Any solution ?
