Hello,

 

I have a grid like the following:

$("#grid").kendoGrid({
        dataSource: {
            batch: true,
            data: [
                {id: 1, statusId: 1, label: 'item1'},
                {id: 2, statusId: 1, label: 'item2'},
                {id: 3, statusId: 2, label: 'item3'},
                {id: 4, statusId: null, label: 'item4'}
            ],
            model: {
                id: 'id',
                fields: {
                    id: {type:'number', editable: false},
                    statusId: {type:'number', editable: true},
                    label: {type:'string', editable: true}
                }
            }
        },
        columns : [
                   { field: 'statusId', values: [ {value:1, text:'Status1'}, {value:2, text:'Status2'} ] },
                   { field: 'label'}
        ],
        editable: true
    }).data("kendoGrid");​

 

statusId column contains an identifier according to the linked values dictionary. When I double click a statusId cell I get a dropDownList with Status1 and Status2 options.

 

Then if I click a statusId cell having non empty value (e.g. row 1), change statusId to another value, click on another row - statusId text is properly updated.

But if I click a statusId cell having an empty value ( row 4), change statusId to​ any non empty value, click on another row - statusId text is not updated in the row 4 statusId cell.

Could you help to solve this issue?

The ideas is to have nullable statusId , linked to a dictionary, where null value is missing. Everything works fine if I try to ​change not empty value. But doesn't work what I try change empty value to not empty.

Hi Vitaliy,

Basically the editor need to have "valuePrimitive" option set to true when the initial value might be null. This option can be set using custom editor as seen in the following demo:
