    hello there

    I´m running into a strange kendo error when my code is updating the grid,  but it only happens sometimes

    but never after a refresh of the page only when data has been added once to the grid and then I´m getting a new datasource and adding it to the grid then this happens sometims


    the probelm lies in this function:

    _hideResizeHandle: function() {
                    this.resizeHandle && (this.resizeHandle.data("th").removeClass("k-column-active"),
                    this.lockedContent && !this._isMobile ? (this.resizeHandle.off(We).remove(),
                    this.resizeHandle = null ) : this.resizeHandle.hide())


    I´ve attached a picture of the error

    Hello Karl,

    The error can occur if the Kendo UI Grid is initialized more than once.


    If you need to refresh the Grid data manually, use the read method of the Grid's dataSource instance:


    If you need to recreate the Grid, then destroy it first, and empty its container <div>.


    If additional assistance is needed, please provide the following information:

    1) An isolated fully runnable example that reproduces the issue.
    2) Scenarios when the issue is reproduced.
