Hi there,

 

I took the code from Kendo Dojo library and modified it to the following and I was wondering if it can be grouped by country.  I have a similar sample and it doesn't work.  TIA

Steve

Hello Steve,

 

In order to achieve the described functionality you could use the grouping configuration of the data source. For your convenience I updated the provided code snippet -  http://dojo.telerik.com/asitO

Hi Plamen,

 

Thanks for the solution, but when I added to my project, the items are now showing up as undefined..  Here is my actual trimmed down code.

var ds = []; // ds is being populated before entering the code below.

$("#grid").kendoGrid({
        dataSource: {
            data: ds,
            schema: {
                model: {
                    fields: {
                       ...
                        jobType: { type: "string", editable: true }
                    }
                }
            },
            pageSize: 10
        },
        editable: true,    
        navigatable: true,
        selectable: "inline",
        pageable: {
            input: true,
            numeric: false,
            refresh: true,                    
            buttonCount: 5,
            pageSize: 10,
            pageSizes: [10, 20, 30, 50]
        },
        columns: [
{ other fields...},
            { field: "Col1", title: "Type", width: "130px" },
            { field: "Col2", title: "Description", width: "300px" },
            {
                field: "jobType",
                title: "Create Option",
                width: "175px",
                template: "#=jobType#",                
                editor: TypeDDL
            }
        ]
    }).data("kendoGrid");

function TypeDDL(container, options) {
  var DDLData = [];
  
for (var i = 0; i < DDLArray.length; i++) {

for (var k = 0; k < DDLArray[i].Type1.length; k++) {
DDLData.push({ Id: DDLArray[i].Type1[k].Id, Description: DDLArray[i].Type1[k].Description, Code: "TYPE-A" });
}

for (var j = 0; j < DDLArray[i].Type2.length; j++) {
DDLData.push({ Id: DDLArray[i].Type2[j].Id, Description: DDLArray[i].Type2[j].Description, Code: "TYPE-B" });
}
break;
}


$('<input id="' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList({
optionLabel: ' ',
dataTextField: "Description",
dataValueField: "Id",
select: onSelect,
dataSource: {
data: ticketClassData, 
group: { field: "Code" }
},
group: "Code"
});
}

Hello Steve,

I see that in the provided code snippet ticketClassData is used as data source instead of DDLData. If this is intended make sure that it contains object/s with "Description" field and "Id" field, since these are specified for dataTextField and dataValueField. 

However in case you would like to use DDLData as dataSource replace ticketClassData.  Please keep in mind without having a simple project where the issue could be reproduced we are not able to say what is the exact reason for the observed behavior.
