Issues during Version Upgrade to R1 2020 (2020.1.114)

[Nallan Krishnan]

Hi,

 

We are currently using Telerik UI ASP .NET AJAX version 2011.1.519 Utlimate suite. Now, We have downloaded & upgraded to is R1 2020 (2020.1.114). 

we are having the following issues.
1. In a page, we have fields (textboxes, dropdown, etc) and "Add" button and a grid. When we fill the data in the fields and click on Add button, the row gets inserted in the grid. But, after that, we are not able to click on any controls in the page. We are getting the following error.
Uncaught DOMException: Failed to execute 'insertRule' on 'CSSStyleSheet': Failed to parse the rule '

        /*.RadGrid_Default .rgHeader {
            color: #333;
        }'.

2. We are opening multiple modal windows as Parent and Child combinations. In this version, when we open the Window A and then, it is supposed to open Window B. But, Window B gets opened behind Window A.

Please let me know the fix for this.

Hi Nallan,

The first error is discussed in the following help article: https://docs.telerik.com/devtools/aspnet-ajax/controls/ajaxmanager/troubleshooting/known-reasons-for-error-messages.

I am not aware of the second issue and we will need a reproduction project.
