Slow Performance when include RadRating Control in RadGrid

[ezequiel]

We have a RadGrid that include a column with RadRating control. 

Our problem is that Grid takes too much time to load in the browser (aprox 8 seconds). 

The ItemTemplate contains only a TextBlock and a RadRating Control.

When i remove the RadRating , the grid load normally (1 second).

The RadGrill run at server and use OnNeedDataSource. And the versión of dlls is 2014

Any suggestions?

 

Thank you,
kind regards

Hi Ezequiel,

My recommendations are:

• Pfollow the RadGrid optimization guidelines at Grid Performance Optimizations. Make sure that the debugging is disabled in the web.config:
  
  

    <system.web>
      <compilation debug="false" />
    </system.web>

• Switch to Lightweight rendering and test again. Set RenderMode="Lightweight" in the web.config globally for all Telerik AJAX components:
  
  Web.config:
  

  <appSettings>
      <add key="Telerik.Web.UI.RenderMode" value="lightweight" />
  </appSettings>

  
  
• Upgrade to the latest version 2019.2.817 (R3 2019) to ensure support for the modern browsers as well as benefit from better stability and performance improvements.
