Telerik Upgradation issue

[Premcoumar]

Hi Team,

I am using Telerik version 2013.3.1114.45 in my Asp.net application. Now I have upgraded my version into 2017.1.228.45. After upgradation lot of telerik functionalities are not working. 

Some of the examples I have described what I have faced so far as follows.

Scenario 1:
I am having rad numeric textboxes in my page. I entered the numeric values into the text box and press enter button.
Actual result: value cleared in the textbox (This problem occurred after upgradation)
Expected result: value shouldn’t be cleared in the textbox.

Scenario 2 :
When I click the button the rad window needs to be displayed but it’s not opening after upgradation.

Scenario 3
Rad grid row selections, tab index for rad grid also not working. Design was collapsed in rad controls.

Note:
If I do any post back, the telerik controls are working good.

Queries
Whether we can upgrade telerik version directly from 2013.3.1114.45 to 2017.1.228.45?

Please provide your valuable solutions.
Thanks in Advance!!!
