Grid Edit Mode: Selecting Item from KendoComboBox does not display selected value.

Hello guys,

I have the following grid:

_grid.kendoGrid({

navigatable: true,

pageable: true,

editable: true,

toolbar: ["create", "save"],

columns: (_columns.length > 0) ? _columns : null,

dataSource: {

data: (_view.data > 0) ? _view.data : null,

pageSize: 100,

schema: {

model: {

id: "id",

fields: _spec

}

},

});

The columns for the grid, and the fields for the schema's model are generated as follows:

var _filter = null;

var _columns = new Array();

var _spec = new Array();

for (_field in _view.fields) {

if (typeof _view.fields[_field] == 'undefined') continue;

var _f = _view.fields[_field];

if (_f.type == 'DropDown') {

_filter = {

field: _f.key,

title: _f.title,

editor: setEditor(_f)

};

_spec[_f.key] = _f.key;

}

else {

_filter = {

field: _f.key,

title: _f.title

};

_spec[_f.key] = {

type: getKendoFieldType(_f),

//editable: true,

validation: {

required: ((_f.required) ? true : false)

//min: 1

}

};

}

_columns.push(_filter);

}

_command = {

command: 'destroy',

title: ' ',

width: 110

};

_columns.push(_command);

When I click an item in the grid that's supposed to be a DropDown, it calls the method "setEditor" as per the code above, it looks like this:

setEditor: function (_field) {

var _context = this;

return function (container, options) {

$.post('/api/',

{

method: 'GET',

api: context.api + _field.populateapi,

json: ''

},

function (data) {

if (!_context.valid(data, true)) return;

var _data = $.parseJSON(data);

$('<input data-bind="value:' + options.field + '" />')

.appendTo(container)

.kendoComboBox({

autobind: false,

dataValueField: 'id',

dataTextField: 'datatext',

dataSource: _data

});

}

},

The grid gets generated just fine. When I click on one of the fields that's supposed to be a drop-down field, it works fine too, the combo-box gets generated. When I selected something for the drop-down, it doesn't dissapear, it also doesn't put the selected text in the field on the grid. I looked at many examples, but I can't figure why this isn't working.

Any help would be appreciated. Thanks for your time!

Grid Aggregates question

I am completely new to KendoUI and am trying to understand the grid aggregates example. I have looked at the example code. Although the example code is very helpful, it doesn't always clarify what one can and cannot do with aggregated data in a grid.

Suppose I have data with fields a,b,c,d,e,f. I want to group the data on field a, but display in the groupheadertemplate only fields b & c and an aggregate based on field d . In the main grid, I want to display d, e, & f in columns, but nothing else. Is this feasible with the current kendo grid? (I assume that templates might be required to achieve this)

How can I select rows in a KendoUI Grid when the datakeys come from several fields?

I have a database table where the primary key is a combination of several fields:

Field1, Field2, Field3

If it was just one field (Field1) I could use

.DataSource(dataSource => dataSource
,Server()
.Model(model => model.Id(p => p.Field1))
)

but how do I set the datakeys/model id when there are several fields?

(If I set the grid to be .Selectable and if I don't set the model id, I get an error message saying that the DataKeys aren't set.)

Thanks.

Best way to handle no data in a DataSource

We are using a DataSource for a search result. When there are rows returned, we display a template in a ListView. When there is no data returned from the search we'd like to indicate 'No records to display' similar to the RadGrid setting.

What is the best way to do this? We can return 'No records to display' in the json response but it will not fit well into our template.
