lerik.Web.UI.Orientation has already been registered.

[Brian Mains]

Hello,

I'm getting the following error in one of my pages:

Telerik.Web.UI.Orientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.

The page was working OK, but now all of a sudden, I'm getting this error.  I have this in a partial view:

<%= Html.RadControlCss<RadCalendar>() %>

<%= Html.RadControlScripts<RadCalendar>() %>

<%= Html.RadControlCss<RadDateInput>() %>

<%= Html.RadControlScripts<RadDateInput>() %>

<%= Html.RadControlCss<RadTimeView>() %>

<%= Html.RadControlScripts<RadTimeView>() %>

<%= Html.RadControlCss<RadTextBox>() %>

<%= Html.RadControlScripts<RadTextBox>() %>

<%= Html.RadControlCss<RadDatePicker>() %>

<%= Html.RadControlScripts<RadDatePicker>() %>

<%= Html.RadControlCss<RadTimePicker>() %>

<%= Html.RadControlScripts<RadTimePicker>() %>

<%= Html.RadControlScripts<RadDateTimePicker>() %>

<%= Html.RadControlCss<RadComboBox>() %>

<%= Html.RadControlScripts<RadComboBox>() %>

<%= Html.RenderRadDatePicker((rad) =>

{

rad.ID = "StartDate";

rad.SelectedDate = DateTime.Today;

 

}, "Forest") %>

<%= Html.RenderRadTimePicker((rad) =>

{

rad.ID = "StartTime";

rad.SelectedDate = DateTime.Now;

 

}, "Forest") %>

Is this the cause of anything?

Thanks.

It is legitimately being duplicated along with other scripts, and that is causing an issue...

Hi Brian,

I have answered to the support ticket open on the same matter. Here is a quote of the answer:

Hi Brian,

After I've reviewed your code snippet I noticed that you are registering scripts of the control first and then call
RenderRadDatePicker, which also registers the control's scripts. If you need to register scripts only once, remove script registration in the RenderRadDatePicker method. The other option is to rely on RenderRadDatePicker to register the scripts and avoid calling RadControlScripts on the page.

Please give a try and let me know how it goes. If the problem still persists I will ask you to send us a working test project, which reproduces the depicted issue.

Best wishes,

All the best,
