    Hello,
    The performances of the treelist component are very bad if this component contains more than 1000 rows.
    To illustrate this problem, I created a small script: http://dojo.telerik.com/UGUXi

    This script loads a treelist with 2 columns and 8000 rows.
    var data = [{ name: "Jane Doe", age: 30 }, { name: "John Doe", age: 33 }...];
    var treeList = $("#treeList").data("kendoTreeList");
    treeList.dataSource.success(data);

    With Chrome, the rendering takes 1903 ms.
    But with Internet Explore 11, the same tree rendering takes 24160 ms.
    Why the treelist rendering is so slow with IE? 

    For information, I tested the same script with the very last version of Kendoui (2014.3.1125) but unsuccessfully.

    Any tips are welcome because this problem is quite critical for me.

    Thanks,
    Luc

    Today, I modified a little bit the test script: http://dojo.telerik.com/UGUXi/4
    Now I use the following method to fill the treelist:
    var data = [{ name: "Jane Doe", age: 30, parentId: null }, { name: "John Doe", age: 33, parentId: null }...];
    var treeList = $("#treeList").data("kendoTreeList");
    treeList.dataSource.data(data);

    But unfortunately, the rendering with IE is not faster....

    Cheers,
    Luc

    Hello Luc,

    As we already discussed the same issue in the other support thread that you created - currently there are not specific options or recommendations that you can use with the Kendo UI TreeList in order to increase the performance in IE. We are working on finding some optimization points that we can use and speed it up in IE, however I cannot give you any specific information or a release date.

    Hello Luc,

    Currently there are no updates regarding the performance of the TreeList widget in IE11. As soon as more information is available, it will be posted with a Kendo UI release.
