Templates in Column attributes no longer supported?

[Erik]

As recently as version 2022.3.1109, I could set a grid column attribute (e.g. class) to a template and easily get conditional formatting like different cell background colors depending on value:

    columns: [
                    { field: "OrderDate", title: "Order Date", format: "{0:MM/dd/yyyy}" },
                    { field: "Freight",  
                      attributes: { 
                                    class: "#: ClassFromFreight(data.Freight) #" 
                                  } 
                    }

Since 2023.1.117, this no longer seems to work. Was this an intentional change? Is there another way to do this now?

Hello Erik,

There are some changes to the kendo templates evaluation rendering and the attributes logic has changed. Here is how the new attributes setup shall happen:

I have modified the Dojo demo based on the shared server response and columns binding:

Dojo: https://dojo.telerik.com/OqInOluP

{ field: "Freight",  
  attributes: attributesHandler
 }
...
function attributesHandler(data) {
   return { class: `${ClassFromFreight(data.Freight)}` }
}

Please let me know if you have any questions.

Thank you! That works for me.
