Hi, I have a situation where the field in a grid column is an ID, we display a description using the template.  In this case, it's a grade level, and for example "0" is "Kindergarten".  We want to display Kindergarten instead of 0 if possible in the group header, it's clearer to our users.

Here is the current column definition.  I've tried different things using a function, haven't found the right code, if it's even possible.

{ field: "GradeLevelId", title: "Grade Level", width: 120, template: function (dataItem)
    {
    return dataItem.GradeLevel;
    }
    , aggregates: ["count"],
    groupHeaderTemplate: "Grade Level: #=value# - Count: #=count#"
},

What I would like it to have the GradeLevel field show somewhere in the GroupHeaderTemplate instead of/or even in addition to, the value that is the GradeLevelID.

Thanks for any help.

Lisa

Hi Lisa,

Please check the fields which can be used in the groupHeaderTemplate property of Kendo UI Grid:

http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#configuration-columns.groupHeaderTemplate
 
Although it is not possible to access row values within the groupHeaderTemplate directly, you could use the Grid's DataSource for getting reference to particular values. For your convenience here is a basic example:
