Hi!

Is there any way to add dynamic default values? When I push the "Add row" button a new row with a new default value (max value + 1) for count column should be added.

Example:

.ToolBar(toolbar => {
toolbar.Create().Text("Add row");
})
...
.Model(model => {
model.Id(n => n.ID);
model.Field(c => c.count).DefaultValue(<this value needs to be max value + 1>);
model.Field(c => c.count).Editable(false);
})

I have tried to adding an event on .Events( e => e.Change("MyFunction")) but the row adding is done after MyFunction event is fired.

Inline Editing in Grid Model is Null When in Window

I have a grid that display details of some items. The grid has a custom command to open a window to display sub details of the selected item. The grid that is displayed in the window that opens has inline editing turned on. When I try to perform an update / create / delete, the Action is properly called, but the passed in model is null.

@(Html.Kendo().Grid<Carrier>()

.Name("grid")

.Columns(columns =>

columns.Bound(p => p.Name).Groupable(false).Width(125);

columns.Bound(p => p.AuthorityReceived)

.Title("A")

.Filterable(false)

.Width(40)

.ClientTemplate("<input type='checkbox' disabled='disabled' #= AuthorityReceived ? checked='checked':'' # />");

columns.Bound(p => p.W9Received)

}

catch (DbException ex)

}

If I move the Grid out of the window, the model that is passed to my Controller's actions is no longer null. Any idea why this would be?

BUG REPORT - Grid Custom Editor Template JavaScript comments would throw error

How to reproduce.

Have a Grid setup,

Use Template like this.

.Editable(e => e.Mode(GridEditMode.PopUp).TemplateName("Example"))

Inside Example Template

Get something like this to the bottom of the page other than your normal input:

<script>

$(document).ready(function () {

setTimeout(function () {

// comments that will cause problem

if ($("#hideClassId").val() > 0) {

$("#tClassId").hide();

$("#tClass").show();

}

});

// comments that can cause problem

$("input#IsActive").on('change', function () {

$('#ActiveWaiting').prop('checked', false);

});

// comments that can cause problem

$('#ActiveWaiting').on('change', function () {

$("input#IsActive").prop('checked', false);

});

</script>

Then the popup would freeze.

This is what the error would look like in the console.

Filtering grid with data from resource file

I have table in database which contains events of a system and these events have severity code and event code. These codes have to be localized, it means the text for the severity and event codes should be taken from resource files.

Here is how we construct data for the grid:

public ActionResult GetEvents([DataSourceRequest] DataSourceRequest request)

{

IQueryable<SystemEventGridModel> data = SystemEvent.GetSystemEventFromDatabase().Select(systemEvent =>

new SystemEventGridModel

{

Id = systemEvent.Id,

EventCode = systemEvent.EventCode,

SeverityCode = systemEvent.SeverityCode,

Date = systemEvent.Date,

Node = systemEvent.Node,

IsActive = systemEvent.IsActive

});

DataSourceResult dataSourceResult = data.ToDataSourceResult(request);

foreach (SystemEventGridModel gridModel in dataSourceResult.Data)

{

gridModel.EventText = Language.ResourceManager.GetString($"EventText{gridModel.EventCode}");

gridModel.SeverityText = Language.ResourceManager.GetString($"SeverityText{gridModel.SeverityCode}");

}

return Json(dataSourceResult);

}

Then in the grid we show the localized text but not the codes:

@(Html.Kendo().Grid<SystemEventGridModel>()

.Name("SystemEventGrid")

.Columns(columns =>

{

columns.Bound(x => x.Node).Title(Language.SystemEventGridModelTitleNode);

columns.Bound(x => x.SeverityCode).Title(Language.SystemEventGridModelTitleSeverityText).ClientTemplate("#=SeverityText#").Filterable(x => x.Multi(true).CheckAll(false).ItemTemplate("function(e){return columnFirtalableItemTemplate('SeverityCode', 'SeverityText')}"));

columns.Bound(x => x.EventCode).Title(Language.SystemEventGridModelTitleEventText).ClientTemplate("#=EventText#");

columns.Bound(x => x.Date).Title(Language.SystemEventGridModelTitleDate);

columns.Bound(x => x.IsActive).Title(Language.SystemEventGridModelTitleIsActive);

})

.DataSource(binding => binding.Ajax().Read("GetEvents", "Home", null))

.Sortable()

.Filterable()

.Pageable(x => x.Refresh(true)))

The problem is that we can't use the standard filtering for the columns (e.g. EventText) which do not existing in database and are taken from different places:

http://imgur.com/a/bcV7i

Is there a way to apply the filtering for the text and search by code from database?

P.S. I attached only the source files (models, views and controllers) for the example code.

Empty a div if no records are returned by kendo grid on filtering

I have a kendo grid which is defined as below

$('#BrowseSchool').kendoGrid({

columns: [{

title: 'Name',

headerAttributes: { "data-field": 'Name', "data-title": 'Name' },

field: 'Name',

encoded: true

}, {

title: 'City',

headerAttributes: { "data-field": 'City', "data-title": 'City' },

field: 'City',

encoded: true

}, {

title: 'State',

headerAttributes: { "data-field": 'State', "data-title": 'State' },

field: 'State',

encoded: true

}, {

title: 'Zip',

headerAttributes: { "data-field": 'Zip', "data-title": 'Zip' },

field: 'Zip',

encoded: true

}],

pageable: {

buttonCount: 10

},

sortable: true,

selectable: 'Single, Row',

filterable: true,

scrollable: {

height: '200px'

},

messages: {

noRecords: 'No records available.'

},

dataSource: {

type: (function() {

if (kendo.data.transports['aspnetmvc-ajax']) {

return 'aspnetmvc-ajax';

} else {

throw new Error('The kendo.aspnetmvc.min.js script is not included.');

}

})(),

transport: {

read: {

url: '/Student/Student_Read'

},

prefix: ''

},

pageSize: 10,

page: 1,

total: 0,

serverPaging: true,

serverSorting: true,

serverFiltering: true,

serverGrouping: true,

serverAggregates: true,

filter: [],

schema: {

data: 'Data',

total: 'Total',

errors: 'Errors',

model: {

fields: {

Address1: { type: 'string' },

Name: { type: 'string' },

City: { type: 'string' },

State: { type: 'string' },

Zip: { type: 'string' }

}

});

I have a div tag defined as below in my view, where the grid is loaded.

<div id="BrowseSchool" class="browse"></div>

Now I want that if there are no records returned by the Kendo grid when a filter is applied, I want to hide my div inside which kendo grid loads and show a different div.
I have tried adding databound event to my grid like below:

databound: function (e) {

alert("No Data");

//var grid = $("#BrowseSchool").data("kendoGrid");

//if (grid.dataSource.total() == 0) {

// alert("No Data");

// $("#BrowseSchool").hide();

//}

},

But, this doesn't seem to be working, as I didn't get the alert box.
My question is, how can I hide a div if there are no records returned by the kendo grid when a filter is applied?

Thanks in advance!

Change button color/style

Is there any classes I can add to a button to change the styling similar to bootstrap's "btn-danger"?

For buttons that do potentially dangerous things, I would like to add special styling to them but not have to worry about if the text color will be correct. Currently there is the "Primary" attribute, but it'd be great if there were other categories.

I understand adding features like that isn't easy to do quickly, but if there are any classes I can add to a normal kendo button to change color and style that's be great!
