I've been implementing multi-column headers in grid and I've found out that I can't change type of columns that are part of
this "multi-column headers". Here is the demo that reproduces it: https://dojo.telerik.com/UbAJeYUJ.
I've taken it from https://demos.telerik.com/kendo-ui/grid/multicolumnheaders.
In this demo I've changed "Company name" column to date and it works. However I've also changed "Country"
column type to date. This column is part of "Location" column and changing "Country" type doesn't seem to work.
Is it the problem of wrong configuration?

Hello Namysław,

 

Thank you for writing us.

You can achieve this requirement by using the schema.model of the DataSource instance in order to define the field types:https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/configuration/schema#schemamodel
I've modified the provided sample to apply the solution:
https://dojo.telerik.com/UbAJeYUJ/8

It works properly on my side. Feel free to give it a try and let me know if it works correctly on your side, too.

Hello Eyup,

Thanks for response! I've changed the configuration and added schema to dataSource and it appears to be working now!
However is it intended to work that way? I mean, I can change the type of column that is standalone (not a part of multi-header)
when specyfing column configuration (title, field, width, etc.). Why then isn't it possible in case of multi-header column config?
I've found it a bit misleading.

Hello Namysław,

 

Yes, I think generally, this can be considered as a bug. And I will log it in our system.

Thank you for bringing it to our attention. I have updated your Telerik Points as a token of gratitude.
