Is there any way to implement more complex filtering with a customer GridFilterCell (https://www.telerik.com/kendo-react-ui/components/grid/api/GridFilterCell/) component?

Currently it fires an OnChange event to the column but can only pass one operation and value to the column, which I presume then translates that to a FilterDescriptor. But is there a way (or a plan on the roadmap) to just pass a FilterDescriptor instead, so one could create a custom FilterCell that returns rules of the type "this value OR this value".

The FilterDescriptor objects are quite flexible and powerful, but the GridFilterCell has no way to tap into that flexibility that I can currently see.

Examples would be things like making a GridFilterCell with a Toggle between MondayWednesdayFriday and TuesdayThursday for a field showing day of the week, or other different groups of values in an enum column. But currently You can only pass a single operation of Equals or Contains or Greater than, so you could pick an individual weekday, but not something more complicated like a "Hide Weekends" button.

Hi, is there a way to achieve a Grid line the below link?

 

https://www.w3.org/WAI/tutorials/tables/multi-level/

 

I know we have a similar case, https://www.telerik.com/kendo-react-ui/components/grid/columns/headers/ but I am more interested in achieving the multi-level headers.

 

Please advice.

Grid toODataString method is encoding special character. I don't want grid to do that that encoding; In fact i want my api to take encoding responsibility.

Can i stop grid to encode special characters. Is there any configuration for that.

I've noticed what I think is a bug with the dropdown. If you bind a dropdown to a value (controlled in component state), you can have the value be undefined to start, and you get a dropdown with no selection. However, if you then manually select one of the entries, and programmatically set the value back to undefined, it does NOT clear the selection, even though the value (correctly) is undefined.

Is there some trick to this? For comparison, I used a vanilla textbox and the value does correctly clear, so I am pretty sure this is a Kendo issue.

Hi,

I was checking your HOC withState grid and can you give an example when this approach could be used? https://www.telerik.com/kendo-react-ui/components/grid/data-operations/local-operations/

Because it is possible to achieve the same behavior without the HOC like this https://stackblitz.com/edit/react-sn578k and I am just interested if there is any reason do it with HOC.

So I don't know if this is by design/mistake/overlooked but it seems multiselects do not apply the id or name property i manually set them when being rendered. 

 

see example project here: 

https://stackblitz.com/edit/react-kjdntt

 

 

 

It would appear your numeric textbox control does honour these settings but i can only assume at this stage that all the dropdown based ones do not honour it. 

(see attached image for console output)

This is causing me some problems with a generic form validation component that I am creating where it will display the name of the control(s) that is/are invalid when the form is being submitted for not only your input controls but also standard html controls. 

 

Am I overlooking something here or is there a design decision why this is being done in this way?
