I´m sometimes getting this error: Ucaught TypeError: Cannot read property 'removeClass' of undefined

[Kalli Kaldi]

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.

http://docs.telerik.com/kendo-ui/intro/installation/jquery-initialization#duplicate-initialization

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

http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#fields-dataSource
 
http://docs.telerik.com/kendo-ui/api/javascript/data/datasource#methods-read

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

http://docs.telerik.com/kendo-ui/framework/widgets/destroy
 
https://api.jquery.com/empty/

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.
