Kendo Grid Select Method is working good if you have only one grid on a page, but if you have more than one grid on the page then its not working properly.
To check this issue please check the following code snippet

I also found solution for that, in select method of grid I saw that you guys are doing items=$(items) [Code Line # 25089 in kendo.all.js]
it has to be items = $(that.element).find(items)

I hope this change will be done in next release build.

Thanks,
