Error when render tree with many levels on a dialog in IE8
posted

Hi all,

I have an issue with tree when use IE8. My tree has 3 levels. I created an example to test and result as below:

- Browser IE9-IE11, Chrome, FF: work fine with my tree on both: view & dialog

- IE8:

  • If I render my tree on normal view => this still works fine
  • If I render my tree on a ig-dialog with 2 levels => this still works fine
  • If I render my tree on a ig-dialog with 3 levels => I cannot continue to do anything due to there's an error pop-up prevents all. 

Have you any idea for this?

Thanks,

Ngan

    Hello Ngan ,

     

    Thank you for posting in our forum.

     

    I've looked into your sample and it appears IE8 cannot handle such a large amount of data being loaded at once in the tree. Since the scripts take longer time to process the whole data, Ie8  shows that message.

     

    One possible way to improve the performance would be to use the LoadOnDemand feature of the tree.

    You can find an online example of how it works and how it can be implemented here:

    For detailed information on the LoadOnDemand feature you can also refer to our documentation:

    http://help.infragistics.com/doc/jQuery/2014.1/CLR4.0/?page=igTree_Optimize_Performance.html

     

     

    Let me know if you have any questions.
