The Grid:
the fields "_status", "_country_id", "_county_id" have integer values in database, but we want to show string values to the user. So we use the "values" parameter that is an array. In the case of _status for example we use:
Everything works fine...
The other two, however are arrays that are created from datasources that are populated from the server. That means the action is asynchronous. So if you try creating datasource->array->grid asynchronously the array might not be populated so the grid shows integer values instead.
If i have one such datasource i use the "change" event of the datasource to create the array and then the grid. For example:
This works just fine... But what should i do now that i have two (or maybe more) foreign keys that need integer->string modification?
Just to know, i have tried creating the second datasource inside the change event of the first and then creating the grid inside the change event of the second. Doesn't work! And is far from elegant solution. Any ideas telerik team and users?
$('#' + idGrid).kendoGrid({ dataSource: dataSource, height: 400, toolbar: [{name: "create", text:"Create County"}], columns: [ { field:"_id", title: "ID", width: "50px" }, { field: "_status", values: status, title:"Status", width: "100px", editor: status_dropdown }, { field: "_country_id", title: "Country", values: countries, width: "50px", editor: country_dropdown }, { field: "_county_id", title: "County", values: counties, width: "50px", editor: county_dropdown }, { field: "code", title: "Code", width: "150px" }, { field: "name", title: "Name", width: "150px"}, { field: "localname", title: "Localname", width: "150px"}, { command: ["edit", "destroy"], title: " ", width: "200px" }], editable: "popup", sortable: { mode: "multiple", allowUnsort: true }, filterable: true, resizable: true, groupable: true, pageable: { pageSize: 30, refresh: true }});the fields "_status", "_country_id", "_county_id" have integer values in database, but we want to show string values to the user.
