Upgrade Issue RadGrid _updateFilterControlValue

Hi there,
After I upgrade my project from 2012.3.1016.40 to 2013.3.1114.40 I receive a javascript error.

JavaScript runtime error: Unable to get property 'getElementsByTagName' of undefined or null reference

This occurs with the call _updateFilterControlValue. Below is the code we use to filter the grid. It doesn't seem to matter if it's Firefox, IE, or Chrome. The error still occurs.

var filterExpression = new Telerik.Web.UI.GridFilterExpression();

var filterFunction = Telerik.Web.UI.GridFilterFunction.EqualTo;

filterExpression.set_fieldName("iExpertID");

filterExpression.set_fieldValue(iExpertID);

filterExpression.set_filterFunction(filterFunction);

filterExpression.set_columnUniqueName("iExpertID");

grid.get_masterTableView()._updateFilterControlValue(iExpertID, "iExpertID", filterFunction);

grid.get_masterTableView()._filterExpressions.clear();

grid.get_masterTableView()._filterExpressions.add(filterExpression);

grid.get_masterTableView().set_pageSize(10);

grid.get_masterTableView().rebind();

Html parsing issue

Does anyone have an idea why is this happening??

it happens so randomly and it seems to be related to the ListView control, used IE 9+ and Chrome latest version to test it and it happens on both browsers.

html parsing issue

What is happening here, for some reason the browser suddenly stopped parsing the html and displays the html code instead of the input elements, as you can notice, in the screen shoot, it stops "drawing" the fields and it does not throw any java script or code behind exceptions.

Hi, this is Tom

I have been struggling with raising issues with the demo on your website, which is My Portal dock panel.

You can test that: add two any docks and close those two docks. After that, add new a dock. then you will see the issue.
I do not know how to fix this problem, it takes me so long time to figure it out. Please let me know how to deal with it!!!!!!

To prevent replcement of every space with and to insert nonbreaking space by Ctrl+Shift+Space through RadEditor

Hi,

I want some solution that would handle all the three scenarios mentioned below.
Scenario 1:
I am using Content property of RadEditor to get values entered by the user in the RadEditor control. However, I see that every space in the value entered by user is getting converted to  . For example, if user has entered the value as - 'Hi Hello' in the editor, the value we get from RadEditor1.Content is - 'Hi Hello'. I don't want this to happen.

Scenario 2:
Also, my requirement is that in the same editor the user should be able to insert nonbreaking space by Ctrl+Shift+Space. For example, if the user types 'Hi(Ctrl+Shift+Space)Hello' we must get the value as 'Hi Hello'.

Scenario 3:
Also, if user manually types   in the editor, it should be retained as it is and should not get replaced with space.

I tried using Text property of RadEditor. But it handles only first scenario mentioned and considers Ctrl+Shift+Space as normal space and not as  

Answer through sample code would be helpful.

Thanks,
Prajna
