It seems that adding an via "Insert Symbol" is not working.
We can reproduce this issue on the demo trial: I have downloaded the demo trial as a standalone-application, added the non-breaking space into toolsFile.xm and checked the behavior.
Please see this screencast for more details: https://www.screencast.com/t/J9aB5KdLr
We tried to create a custom ContentFilter that will replace the all zero width space characters to non-breaking space in the content. But that seems not to work as we don't have those zwsp charachters in the content withing the ContentFilter. Tried soluiton based on this post:https://www.telerik.com/forums/zwsp-inserted-into-html-in-chrome
Anyone had this issue before and found a solution?




Hello,
Is there any Math Symbols like WIRIS that could be integrated with RadEditor? I have searched the web for a week with no luck.
Or is the WIRIS fully supported?
Many thanks,
Zeyad.

Hello Telerik team,
I bound dblclick events on each tasks of my radgantt. This binding is made in the PageLoad function of the .aspx page which contains the radgantt.
This event allow the user to display a custom popup rather than the default one.
But I noticed that the execution don't go in my custom JavaScript code (and don't throw the dblclick event or anything else) as soon as I click on the expand/collapse button on a task.
I need that the execution go in my custom JavaScript code even if I click on the expand/collapse buttons.
Is it possible ?
Thanks in advance,

Hi,
I am working on a project where I am using RadTreeList as a
control(creating it programmatically from .cs file).
I am trying to implement excel like filtering on the column
headers but I couldn’t find a straight example/resource which guides me to do
so.
I found a link which has a similar usage in kendo MVC.
https://demos.telerik.com/aspnet-mvc/dialog/treelist-integration
Is there a way we could implement this or a similar excel
filter with RadTreeList?
I want to avoid using a separate control of RadFilter as
demo shows on the website.

Thanks in advance for the help,
