Page Performance Issue when using Flexmonster

Re-Open
Ravi Kumar asked on June 18, 2021

Hi,
 
We have Integrated Flexmonster with Angular, and after setting data to Flexmonster then webpage responsiveness is decreasing gradually.
Tried without Flexmonster and the page supporting good. We tried setting data to Flexmonster twice then automatically page is lagging so much.
Please suggest any solution how to achieve better performance.
 
Regards,
Ravi

Hi Milena,
Thanks for the reply. Please check the below implemented code from our project.
Please check and provide any solution.

Hi, Ravi,
 
Thank you for providing the code from your project.
Our team has carefully checked it and found the possible cause of the issue. Please see detailed info below.
 
In the <fm-pivot> component, the beforetoolbarcreated event is handled by fmBeforeToolbarCreated function. Please note that the beforetoolbarcreated event should be used exclusively for the Toolbar customization. We noticed that the fmBeforeToolbarCreated function is used for other purposes.
Therefore, we suggest:

  1. removing the createFlexmonsterObject() function and the following line of code:
    this.flexMonsterGrid.flexmonster = this.createFlexmonsterObject();

    In the createFlexmonsterObject function, new instance of Flexmonster is created. When you use Flexmonster integration with Angular, the instance of component is created via <fm-pivot> tag. Thus there is no need to create Flexmonster instance once again.

  2. handling cellClick outside of fmBeforeToolbarCreated function.

We also prepared some links that can be useful for your case:

 
Please let us know if our answer helped.
 
Kind regards,
Milena

Hi Illia,
Thanks for following up.
 
We didn’t get much time to change the existing implementation to your suggested one.
Quite busy with Project deployment and other things.
Definitely will contact you if any help/suggestions required.
 
Regards,
Ravi
