The datetimepicker filter is not properly persisted after saving and loading the state of the grid

[El Mehdi]

Hi,

I am facing an odd behavior with the kendo grid menu datetimepicker filter.

Replication (link https://dojo.telerik.com/aFOMARUq):
1- Filter the grid using the "Start" column (select any date or time).
2- Save grid state.
3- Load the grid state.
Check the "Start" column filter.

Observed behavior: the time picker is no longer displayed.

Is there something I am missing? any help or suggestions are much appreciated.

Hi Mehdi,

The JSON.stringify is not capable of serializing function references, so before applying the options you have to manually restore the reference to the filterable.ui setting.

e.g.

              if (options) {
                var parsedOptions = JSON.parse(options)
                console.log(parsedOptions)
                parsedOptions.columns[1].filterable.ui = dateTimePickerFilter;
               ...

Below you will find a modified version of the provided sample:

Hi Georgi,

That's exactly what I was looking for.

Much appreciated,
